Both are often true, but there is also some truth to the idea that LED plant lights can damage your eyesight.
With that, let's answer the question that brought you here.
Does LED grow lights harm your vision?
Short Answer
Yes, LED grow lights can damage your eyes.
Whether this is something you need to be concerned about depends on the type of light, the intensity, and the duration of exposure.
More details are below.
What Types Of Light Can Cause Us Harm?
Any type of light can be harmful to our eyesight if it is powerful enough. If you’ve ever looked directly at a powerful light source, you’ll know this (and hopefully have looked away quickly enough before any serious harm was done).
However, some types of light are much more harmful than others and even small amounts of certain light can damage our eyes.
Before we discuss those types of light, let’s take a look at the complete electromagnetic spectrum.
As you can see, the range of light that is visible to the human eye occupies a narrow band that is sandwiched between UV light on the right (shorter wavelengths) and infrared light on the left (longer wavelengths).
To simplify things a bit: the shorter the wavelength, the greater the harm to us.
Thus, the wavelengths of light we need to worry about most are blue light and UV light, with the latter being more dangerous than the former.
UV light is further broken down into UV-A, UV-B, and UV-C. UVA is the closest to visible light, which means it has the longest wavelength and is also the least harmful. UVC is the most harmful.
Light from the sun contains all three, but our atmosphere filters out most of the UV-C light. UV-A and UV-B get through the atmosphere and cause us harm. They are the reason we need to wear sunscreen and UV-blocking sunglasses.
When it comes to artificial grow lights, they all contain varying degrees of blue and UV light. Reddish grow lights, like HPS, only contains small amounts. Bluer lights, like Metal Halide or fluorescent, contain much more.
LED grow lights are a little more complicated.
Are LED Grow Lights Harmful To Humans?
It depends.
LED plant lights with a lot of blue and UV diodes can be harmful. The same goes for all-white lights that emit a cooler white light (5000 Kelvin and higher).
The type and amount of harm an LED light can cause depends on the color and the intensity. Any powerful light can hurt our eyes if we stare directly at it, but that is an easy enough thing to avoid. Just don't stare into your lights.
Apart from that, let's look at the actual effects of blue and UV light, the two wavelengths that are harmful to humans.
Effect Of Blue Light On Humans
The most commonly known negative effect of blue light is what it does to our sleep.
During the day, blue light keeps us alert and awake. But exposure to blue light at night suppresses the secretion of melatonin, which is a hormone that influences circadian rhythms. This makes it harder for us to fall asleep and leaves us more tired and sluggish.
There is also a possibility that lower melatonin levels are linked to obesity, diabetes, and some types of cancer, but much more study is needed to determine if there is, in fact, a connection.
Effect Of Blue Light On Our Eyes
blue light effect on eyes
Blue light can also negatively impact our vision. Our cornea does not do a good job of blocking blue light, meaning almost all of the blue light that hits our eyes penetrates all the way through to the retina.
Too much blue light has been proven to damage light-sensitive cells on the retina. This brings about changes that are similar to macular degeneration, which can result in permanent vision loss.
This is obviously an extreme case and would require a lot of blue light exposure, but we get much more of it these days than ever before, thanks to our various screens (computer, phone, TV, etc.). Adding in high amounts of blue light from your grow room is a definite cause for concern.
The research so far is limited and we lack a good understanding of the long-term effects of too much blue light, and even how much blue light is too much. Nevertheless, it makes sense to err on the side of caution and take steps to protect our eyes.
Effect Of UV Light On Humans
UV light affecting the eyes
Many of the effects of UV light are well known. It causes varying degrees of skin damage, from premature aging to sunburn, to cancer. It also causes damage to our vision and that is what is most concerning to us here.
Effect Of UV Lights On Our Eyes
All three types of ultraviolet light can damage our eyesight, but UVC does by far the most damage. Luckily, our atmosphere blocks out most of it, and it is generally not emitted by most grow lights. Those that do contain UVC light, only emit very small amounts.
UVB and UVA are much more problematic. They affect our eyes in very different, but equally dangerous, ways. UVA light passes through our cornea and hits the retina, just like blue light. UVB light is completely filtered out by the cornea and thus can not reach the retina.
Because UV-A light passes through the cornea, it has been linked to conditions resulting from damage to the retina, like certain types of cataracts. It may also play a role in the development of macular degeneration.
Since UV-B light does not hit the retina, it does not cause those same issues. Instead, it may help cause pingueculae and pterygia, which are growths on the eye's surface. It can also cause painful inflammation of the cornea called photokeratitis, which can cause temporary vision loss in extreme cases.
What does this all mean for us?
Well, now that we know how the different types of light affect us, we can better discuss what kind of damage LED lights might be causing. They are not generally strong enough to cause skin damage, so most of the potential damage is to our eyes.
Effect Of LED Lights On Eyes
led diodes bad for eyes
Most LED fixtures contain varying degrees of blue light and UV-A diodes. Some also contain UV-B diodes (very rare) or supplemental UV-B bulbs. These lights may also emit some UV-C light.
We now know that both UV-A and UV-B light can damage our eyes and that blue light can result in negative effects as well. Whether we need to worry depends on the level of exposure.
Do You Need Glasses For LED Grow Lights?
If you just have a small light fixture and/or you don't spend much time beneath the lights, you don't have to worry. The UV levels are not high enough to cause damage with such minimal exposure.
However, if you have powerful lights and you spend a lot of time working beneath them, I highly recommend you get some form of eye protection.
LED Grow Light Eye Protection
Glasses protect from too much light
You have several options.
Most people will recommend against regular sunglasses. That is not because they don't protect the eyes. Rather, it is because they are not designed for the unique light emitted from a grow light.
This means that your plants will not look natural if you use regular sunglasses.
Grow glasses that are tuned to a specific spectrum will result in your plants looking completely natural when viewed through the glasses. This makes it much easier to inspect your plants and detect any discoloration or other signs of problems.
The main issue here is that you need glasses that are made for the exact spectrum of your lights. General LED glasses will work for most of the lights that have a mix of primarily red and blue diodes, but they will not be perfect, since all of those lights have a slightly different spectrum.
If you have an all-white LED, then you'd actually be better off with HPS or MH glasses, depending on the color temperature of your light (MH glasses for cooler lights and HPS glasses for warmer lights).
Regular Sunglasses?
If you don't care too much about the plants looking unnatural (i.e. pink/purple), then you can use a pair of regular sunglasses.
Just make sure they protect from UV rays. Many do not protect from UVC, so make sure yours do, if you have a light that emits UVC rays.
Other Common Questions
Here are the answers to a few more common questions we get regarding grow lights and their impact on our health.
Are HPS Lights Bad For Your Eyes?
As mentioned above, high-pressure sodium lights contain a lot of red light, a small amount of blue light, and very little UV light. For that reason, they are safer for your eyes than most other types of grow lights.
That said, HPS bulbs are very powerful and can cause damage merely through their intensity. You definitely want to avoid staring directly into the lights.
Can Grow Lights Cause Cancer?
As mentioned above, there is some concern that prolonged blue light exposure could cause cancer, but this has not been studied, so nothing is known for sure. The same goes for UV light.
What IS known is that UV light can cause skin cancer. This is not something you have to worry about with grow lights, since they do not contain high enough levels of UV light. Just don't lie directly beneath a powerful grow light naked for hours at a time and you'll be fine.
Actually, maybe don't lie under one naked for any amount of time. That's just weird.
Are Grow Lights Safe For Humans?
Yes, as long as proper precautions are taken, grow lights are safe for humans.

Step 5: Diagnose Pests (sometimes you never actually see the bugs)
]]>Arm yourself with the knowledge of the following 5 simple things to check when your plants get sick, and you’ll know how to give your plants a 100% recovery.
Step 1: Verify Watering Habits & Root Health
Step 2: Diagnose Nutrient Problems & Deficiencies
Step 3: Check Environment
Step 4: Identify Light Issues
Step 5: Diagnose Pests (sometimes you never actually see the bugs)
These tips were specially made to fix a whole host of possible issues with minimal work.
Catching and solving problems quickly means bigger, bulkier, more potent buds. Your cannabis plants will love you for it!
Step 1: Verify Watering Habits & Root Health
The roots are the heart of your cannabis plants. When roots become sick, the health of the entire plant quickly falls apart.
Drooping or wilting is the main symptom of watering or root problems. Plants droop when they have “wet feet” for too long, if they get too dry between waterings, or if their roots get sick.
Yet sometimes, cannabis plants with unhappy roots show no signs that there are problems until things become grim. Luckily, it’s easy to check for issues and even easier to solve them once you know what to do.
Watering and root problems can also cause a variety of other symptoms including yellowing, nutrient deficiencies, leaf spots, brown edges, curling, and more.
What to do? Use the checklists below to diagnose whether your plant is over-watered, under-watered, or has a root problem.
Check for signs of under-watering
Overwatering is easily the most common growth problem, but it can be tricky to diagnose. Go through this list carefully and if you suspect overwatering, check the link below to see pictures and get detailed solutions.
Check for signs of under-watering
Root Rot
In hydroponics, root health is key to success. React quickly if you noticed roots look brown or unhealthy
Tips for healthy roots
Step 2: Diagnose Nutrient Problems & Deficiencies
Cannabis nutrient problems are often closely related to the pH at the roots of your plants. That’s because when the root pH is off, it can cause your plant to show signs of a nutrient deficiency, even if the nutrients are actually there in the soil. Even if you’re providing nutrients, plants may get nutrient deficiencies if the pH is off.
This magnesium deficiency is the result of the pH being too low at the roots.
Growers need to monitor their root pH in almost all growing setups for the best results. Cannabis plants prefer a slightly acidic root environment. Some growers get lucky and the pH of their water happens to be just right without additional adjustment or monitoring. Yet most growers will achieve better growth and plant health by monitoring pH. Being aware of your pH helps you understand when things are going wrong. Luckily, nutrient and root pH problems are easy to solve with the right information.
Cannabis plants cannot absorb nutrients properly if the pH at their roots is too high or too low. So even if the nutrients are present, you’ll still get what looks like nutrient deficiencies if you don’t maintain the right pH.
This copper deficiency is the result of bad pH even though the plant was getting nutrients in the water.
For those of us who aren’t lucky enough to magically have the right pH, here’s how to ensure your plants get exactly what they need.
What to Do? The goal is to give your plant exactly the kind of nutrients it needs to thrive and provide the correct pH at the roots so your plants can properly absorb nutrients.
It’s important you learn a little bit about what kind of nutrients are needed by the cannabis plant during different stages of growth. These days, there are lots of nutrient systems available that are specifically formulated for plants like cannabis, and they help take all the guesswork out and give your plants exactly the nutrients they need. It doesn’t have to be expensive to provide everything your cannabis plant needs!
Once you’re positive you’re watering correctly, providing the nutrients your cannabis needs, and you’ve adjusted the water pH to the proper levels, nutrients problems should start clearing up quickly. Remember, if leaves get damaged from a nutrient problem, it is unlikely that a particular leaf will ever recover and turn green. What you’re looking for is that the problem stops spreading and that any new growth appears green and healthy.
Step 3: Check Environment
If you’ve ruled out problems with watering, nutrients, and pH, there’s a strong chance something with the environment is causing your symptoms.
A good growing environment is crucial to the health of your plants. When the temperature (and to a lesser extent the humidity) is too high or too low, your plants will not grow properly no matter what else you do. Plants seem unhealthy and buds just don’t fatten up. You may also end up with problems related to plant stress such as hermies.
Too much heat (or arid conditions) will generally sap the strength of your plant and force it to drink more water than normal for plant transpiration (the process of water movement through a plant and water evaporation through leaves, stems, and flowers). A plant drinking more water than usual can have unexpected consequences. Sometimes hot, dry temps can cause unexpected nutrient burn (plant tips curl or turn brown from high levels of nutrients) because your plant is absorbing more nutrients than normal at the roots, alongside the extra water.
If there is a particular source of heat that is harming the plant (like a hot grow light), you’ll know because the leaves closest to the source of the problem will wilt and turn a brownish color.
A generally too-hot environment can cause the stems of your plant to droop as if under or over-watered, even when there’s plenty of water at the roots.
Plants that suffer from extreme heat stress for too long may not recover and sometimes are unable to straighten their posture and continue growing.
Heat stress dramatically slows down growth and buds don’t fatten as much as they could
One of the reasons you need great air circulation is your plants “breathe” CO2 during the light hours, almost like we breathe oxygen. Unless your plants are in a big open space with lots of air, or you are supplying your plants with CO2, you need to have some sort of exhaust system to pull away from hot, stale air and bring in new fresh air for your plants.
If you’re worried about the smell of cannabis, make sure any heated air being vented outside grow room/house gets filtered to remove the scent of cannabis. For example, many growers choose to get a carbon scrubber to “scrub” all odors before the hot air is vented. By creating good suction with an efficient exhaust system and adding a carbon scrubber, you can basically eliminate all smells from the grow room, inside and outside of the house.
An exhaust system doesn’t have to be anything fancy. At its simplest, an exhaust system can be two holes and a fan (with the fan place in one of the holes pointed out from your grow area). Having a fan constantly pulling hot air out and bringing fresh air in from your intake hole will help ensure that your plants have the fresh air they need.
Because your plants need CO2 when the lights are on in order to function properly, a completely sealed off grow box is not good unless you’re artificially adding CO2. Your plants will suffer if they don’t get enough CO2 in a sealed grow box even if the temps are completely under control.
Some growers like to supplement their plant with extra CO2 in an attempt to increase yields or growth rate, but it’s important to note that the amount of CO2 found in regular air is plenty for your plants unless you have extremely powerful grow lights (1000W HPS, high power LEDs, etc).
For most growers, a proper exhaust system and a few strategically placed fans are all you need when it comes to air circulation.
Watch Your Humidity, too! Very high or low humidity can cause slow growth, though high humidity may be worse because it can also trigger white powdery mold and bud rot.
Humidity is a term used to describe the amount of water vapor present in the air at any given place, and the amount of water in the air is related to the local temperature.
Humidity measures the amount of water in the air. Humidity between 40-60% RH works great in most situations.
It is common for new growers to not pay attention to humidity at all, and this can sometimes cause otherwise unexpected and/or inexplicable problems.
Cannabis plants can show false signs of nutrient deficiencies when the relative humidity of the grow area drops below 35% RH, especially when things get really dry. Younger plants are most susceptible, though plants often adjust over time many plants are able to grow just fine as long as they’re provided with plenty of water at the roots. Some strains can handle low humidity better than others.
Extremely low humidity can cause plants to grow slower and less healthy.
Young plants, new clones, and vegetating plants that are used to more humid conditions are usually the hardest hit by a dry spell.
In the flowering stage, humidity should be kept below 55% to prevent the chance of mold and increase resin production.
Younger plants usually are fine with high humidity, but humidity is especially dangerous in the flowering stage because the insides of the buds can grow mold and still look fine from the outside at first.
High humidity in the flowering stage causes bud rot, which quickly spreads from plant to plant and can ruin an entire harvest overnight. The leaves on this bud became discolored overnight.
When you look closer, you can see the entire inside has started molding and rotting. This entire bud had to be tossed, and the rest of the plant was harvested immediately before it kept spreading.
In addition to preventing bud rot, there’s some evidence that maintaining a low humidity environment in the flowering stage helps buds produce more terpenes (giving buds a stronger natural scent) and more trichomes (possibly even increasing the potency of your buds!).
What to Do? Get a temperature and humidity monitor. Control heat by whatever means necessary and keep humidity in check using the steps outlined below.
Monitor the temperature and humidity with a thermometer/hygrometer in your grow space.
Regardless of your setup, it’s important for air to be moving around your plants to prevent heat spots, strengthen stems, help stop pests, reduce the chance of mold, and make sure your plants are getting plenty of fresh CO2 to achieve the best growth.
When it comes to fans, don’t point fans directly at plants or they may get windburn. Usually, it’s better to be point fans at a wall to disperse the air or have fans blowing over and under the plant canopy. A fan circulates air in the room and provides a gentle breeze for your plants.
The best-case scenario is you want to set up your fan system so that all the leaves on the plant are gently rustling, yet no stems or branches are waving around from the force of the wind.
When the humidity is too low, it’s important to make sure you provide plenty of freshwater to your plants at all times. You may need to reduce the total amount of nutrients as the plants will drink more water and therefore absorb more nutrients through their roots than when the humidity is not as dry.
When it comes to controlling humidity indoors, you may need to use a humidifier and/or a dehumidifier to keep the humidity in the optimal range. A humidifier adds moisture to the air while a dehumidifier takes moisture out.
Controlling your grow room humidity is one of the tricks that separates the expert growers from the beginners.
You can get some pretty fancy humidity gauges to place in your grow room, and products to help change the humidity are commonly found at department stores, hardware stores, or most stores that sell home appliances.
Here are the most important things to keep in mind when it comes to the humidity of your cannabis grow room.
With the right tools, the task of maintaining humidity can be close to automated, and you will see huge benefits compared to the amount of time and money you invest.
When the air feels moist or humid (or a humidity monitor alerts you to high humidity), it’s extra important to ensure that plants get plenty of air circulation and have lots of air movement. You also want to avoid letting leaves touch each other during periods of high humidity. You can fix constantly too-humid conditions with an exhaust system, fans, and possibly a dehumidifier.
If plants are very leafy and leaves are laying on top of each other, it dramatically increases the humidity of the grow space. In this case, removing leaves (defoliation) can help. Try to remove leaves that are in the lower/middle part of the plant, leaves that are covering bud sites, and leaves that are touching each other making wet spots.
When the air is too dry indoors, you can either choose to let your plants grow hardened to the arid air, or you can use something like a “swamp cooler” (evaporative cooler) to add humidity while also reducing the temperature of your room. A humidifier will also add humidity but tends to raise the humidity of the room.
Step 4: Identify Light Issues
Cannabis loves light! But not too much…
When growing cannabis, the mantra when it comes to lights is usually “More is better!” To be honest…it’s true! More light usually is better!
You see, light is like “food” for your Cannabis plants. When plants are growing very slowly, but aren’t showing signs of other problems, the cause is often that they aren’t getting enough light.
The amount of light you give your plants is strongly correlated with the fast your plants grow, as well as how many buds your plants will produce during the flowering stage.
Many new growers don’t realize they’re not giving their plants enough light. As a very general rule, you want at least 100W worth of electricity going into your indoor grow light to harvest a few ounces. More is often better.
More light = More yields + Faster Growth (up to a point)
If plants are growing very slowly, if they’re not drinking much water, or otherwise aren’t doing well without showing any other major signs of problems, often the problem is the plant simply needs more light to thrive.
As a very general and unscientific rule, a new grower who doesn’t run into major problems can expect…
This rule is referring to how many watts of electricity is actually being pulled out of the wall, not some sort of “equivalent” amount of watts. If an LED pulls 90W of electricity from the wall, you should plug that into the equation, not the claim that it’s “equivalent” to a 400W HPS light. Same for CFLs, if you have a CFL bulb that pulls 26W of electricity from the wall, you should count that as 26W, and ignore the fact that it says “equivalent to 100W” on the front.
Of course, this rule varies quite a bit depending on the type of light, the strain being grown, the size of the plants, etc. However, it’s a good general guide if you’re not sure how much light you need, and it can help you decide if you might not have enough light for your plants.
To put that into perspective…
Highly Recommended LED grow light in that range: Eagle Star 660W (I love this light!)
Keep in mind that there are many other factors that go into this, and this is not a guarantee as much as a general rule. Moreover, many smaller lights tend to get better yields per watt than fewer larger lights. Lights that are kept closer to plants (without signs of light stress) will also tend to produce bigger yields and faster growth. Most importantly, the strain you start with and the training methods you use to get your plants to more efficiently use your indoor grow lights will have a huge impact on your growth rates and final yields.
But can there be too much light?
Yes, there can be too much light!
Unfortunately, more light is not always better. Cannabis plants can be fickle. You want to give them very bright light… but not too much light.
When Cannabis plants are young, they are weak and cannot tolerate much light at all. Yet as they get older, and especially in the flowering stage, Cannabis plants want almost all the light they can get.
The problem of too much light often occurs indoors, when your grow lights are too close to the plants. This essentially gives them their own version of sunburn.
Young plants, seedlings, and new clones are especially prone to suffering from too much light, though it can affect older plants too. The main way you know your plants are suffering from the light burn is if only the leaves closest to the lights are affected, and you’ve already covered all the other possible issues in this article.
The intensity of a grow light that is too close will dry up a plant, cause bleaching/yellowing, turn the edges of its leaves brown and crispy, almost like nutrient burn, and other odd symptoms.
Too high light levels will cause light burn.
High-Pressure Sodium (HPS) lights have the meanest reputation for ‘light-stressing’ plants, but many of the newer, more powerful LEDs (Light Emitting Diodes) do it, too!
What to Do? Most importantly, pay attention to your plant and watch out for signs of light stress, which will only affect the parts of the plant closest to your grow lights.
For HPS, Metal Halide, and CFL grow lights, use the ‘back of your hand’ test.
Back of Your Hand Test – For MH, HPS, CFLs and T5 grow lights (not always effective for LEDs or very high-power HPS lights with strong air conditioning)
LEDs generate very little heat, but can still light-stress plants, so it’s best to keep LEDs the distance recommended by the manufacturer. Each grow light is different, so it’s hard to make generalizations, but just about every LED needs to be at least 10″ inches away from your plants. In my experience, most hobby-sized LEDs (100-300watt true power draw) need to be kept 18-24″ away in my experience. Some LEDs need to be kept even further away, up to 3 feet or more for some of the newer, extremely powerful LED models.
LED grow lights usually need to be kept at least 18-24″ away to prevent light burn.
Use caution when attempting to move your grow lights closer, and avoid moving them more than an inch closer in a day, so you can watch the plant’s reaction.
Make sure your grow space is light-proof! (Unless growing an autoflowering strain)
If you’re growing photoperiod plants, you also need to ensure your grow space is totally light-proof, so light can’t get into the tent when the grow lights are off. Photoperiod plants need complete darkness during their dark period or they’ll never make flowers. If photoperiod plants start getting light at night while budding, it can cause them to herm (buds get seedy) or re-veg (buds die, and the plant reverts back to the vegetative stage).
If you’re growing a photoperiod plant, light leaks can cause seedy buds
Or re-vegging (the main symptoms are rounded leaves on long stems and dying buds)
Step 5: Diagnose Pests (sometimes you never actually see the bugs)
When growing in soil, bugs are a common pest to Cannabis gardens. We believe that growing Cannabis in coco is often simpler for beginners because it automatically eliminates many of the bug problems growers run into when growing in the soil while achieving faster growth.
Sometimes you don’t see bugs. Thrips are an example of a pest that leaves markings on the leaves which can be mistaken for deficiencies, yet you rarely see the bugs themselves.
Broad mites are also commonly mistaken for other issues because the bugs are usually too small to see. Broad mites cause twisted growth and shiny, discolored leaves.
Cannabis russet mites “poop” out extra stuff at the top of the plant that can be mistaken for mold.
However, usually, you can tell when plants have bugs because you see the bugs themselves, or it actually looks like bites on the leaves.
What to Do? If you notice any signs of bugs or mold, don’t wait. Act quickly!
One of the worst types of pests for cannabis growers is spider mites. They actually have earned the nickname “the borg” because of their ability to seemingly come back from the dead and take over an entire grow room or destroy a whole crop.
Spider mites are another common pest. You can often see them moving under the leaves, or you’ll notice the webbing and bite marks.
Fungus gnats are another common cannabis pest. They look like tiny flies buzzing around the soil and are the result of overwatering.
Leafhoppers look pretty, but they munch on your plants so don’t ignore them!
When you believe you have bugs…
As mentioned earlier, good air circulation and a slight breeze are not only good for the plant by itself, but will also disturb bugs and make it harder for them to turn your plant into a home.

Can any led light be used as a grow light?

]]>There was a time when choosing grow lights was simple – all you needed to know was what brand and wattage you wanted. Things have changed. Drastically. The market has been flooded with grow light options and it can be quite challenging to figure out which light is best for you.
If you are new to growing cannabis indoors, it may overwhelm you to see how many different LED grow lights are on the market today. Things such as light spectrum, wattage, and PAR output leave many to wonder what’s actually important. What should you really be looking for when buying a LED grow light and where do you begin? This article will go over the different things you should consider when shopping for LED grow lights .
First of all, you need to know the size of the grow space that your plants will be growing in. Measure your grow space – length, width, and height. Knowing what size grow area you will be growing in is arguably the most important piece of information to know when shopping for LED grow lights . A LED grows light manufacturer will design their grow light for a specific coverage area. The most common coverage areas are 2’x2’, 2’x4’, 3’x3’, 4’x4’, and 5’x5’. As you can see, the length and width are mentioned, but not the height. Hang tight. We will talk about the height of your grow space in a minute. Once you measure your grow space and know what area you need your LED grow light to cover, you can narrow down your search results by filtering to show LED grow lights specific to your grow space.
Now, what about the height of your grow space? That comes into play when we talk about light distance. Every grows light listing should state the coverage area as well as the recommended light distance. The light distance is the distance between the grow light and the top of your plants. Light distance is another thing you need to consider when buying a LED grow light. I’ve had several growers contact me asking for advice on plants that grew too close to their grow light – because they did not factor in the light distance when buying their LED grow light. Let’s go over a quick example. Say your grow space is 4’x4’x6’ (L x W x H) and the recommended light distance on your LED grow light is 24”. So, 6’ (height of grow space) minus 2’ (light distance) equals 4’ tall plants? Right? Wrong! You should also consider the grow pot (which often takes up about 12” depending on the grow pot size) and the “lost distance” above the grow lights which is taken up by the grow light hanging kit.
Photon efficacy refers to how efficient grow lights at converting electrical energy into photons of PAR. On grow light listings, you’ll see it as umol/j. The higher this number is, the more efficient the grow light is at converting electrical energy into photons of PAR.
The industry standard for measuring grow light efficiency is micromole per joule (sometimes written as umol/j, μmol/j, umolj-1, or PPF/W). That means that for every joule of electrical energy (joule = watt * second) a certain number of photon micromoles are produced. One micromole = 602,000,000,000,000,000. That’s a dizzyingly large amount of photons!
In 2020, a photon efficacy of 2.0 umol/j or higher is considered very efficient. Highly efficient LED grow lights ranges from 1.5 μmol/j and up (this number is constantly improving). Many of the most efficient LED grow lights are low power and, as a buyer, you may have to weigh out whether you are looking for efficiency or intensity because at times one can be at the sacrifice of the other. Top brand HPS (high-pressure sodium) lights are around 1.7 μmol/j.
Wall Plug Efficiency
Another measurement relevant to DIY LED grow lights enthusiasts is wall-plug efficiency (WPE). This is a ratio of the amount of energy put in and the amount of light produced. This can be expressed as a percentage, such as 60% “wall-plug efficiency,” which means that 60% of the electricity that goes through the light gets converted into light. The rest gets turned into heat that will need to be dealt with in the grow light itself as well as the room that houses the light.
It’s not typical to rate a grow light’s wall-plug efficiency, but high-quality diodes made specifically for horticulture occasionally have this listed. For instance, high-quality blue LEDs at 450nm can reach wall plug efficiencies of 60%, red LEDs at 660nm with 50% WPE, and green 530nm with 25% WPE. Wall plug efficiency can be calculated using a diode’s radiant flux (not luminous flux, which is a measure of how bright a light appears to the human eye and not how many photons it is producing) divided by the total wattage of electricity the diode uses. Remember to convert between milliwatt and watt, as necessary (1000 milliwatts = 1 watt).
Achieving High Efficiency
Brands increase their efficiency by having high-quality diodes, running them at low energy, having excellent heat management, and using a high percentage of the most efficient diode wavelengths. While some LED companies market themselves as having many different color LEDs, this can often be at sacrificed efficiency, since each color of LED has a different efficiency at producing light. For instance, 450nm, 660nm, and high kelvin white (white LEDs are 450nm with a phosphor coating) are very efficient, while green LEDs are not very efficient.
While there is no doubt that grows light spectrum is important, some studies suggest that even more important than spectrum is light intensity. There are a number of ways of measuring the intensity of a grow light – some good and others bad.
Some of you may be wondering about the LED grow lights that produce over 900 PPFD. Will a PPFD higher than 900 produce bigger buds on your plant? The answer to that is yes - only if you run a high CO2 in your grow environment. CO2 is measured by PPM and the CO2 level outside is 400-500 PPM. Plants grow just fine with that amount of CO2. Some advanced growers will add CO2 into their grow room to get the CO2 PPM in the range of 1,000-1,500. Running a higher CO2 PPM like that will allow your plant to absorb more PAR. On the flip side, if you are not supplementing with CO2 and provide your plant with too much PAR, then your plant could encounter problems.
Many manufacturers list wattage (watts) as a metric to describe the light intensity. However, watts are a measure of electrical consumption and not light output. I will talk more about watts later in this article but wanted to quickly mention it here in the PAR section since it’s often confused with it. Many people assume that the higher the watts means the higher intensity. That is certainly not true. Also, lumens, LUX, and foot candles are other metrics that some grow light manufacturers use to describe the intensity. These are outdated metrics. When you measure light intensity using LUX or foot candles, blue and red light are underrepresented and therefore, you are not getting an accurate measurement of PAR. If a grow light listing lists the watts, lumens, LUX, or foot candles to represent intensity instead of PPF, PPFD, or Photon Efficacy, be cautious!
Wattage
This is the most common measure of grow light intensity and is a measure of electricity (watt = amp x volt). This measure can be misleading, though. Some manufacturers (the better ones) give the actual wattage the unit uses – the wall plug wattage. Others, typically lesser brands, will give you the max wattage rating of the LED diodes. To use a simple example, a grow light could call itself 90 watts if it has thirty 3 watt LED’s, however, it is common practice to run LED’s at half wattage to reduce heat production (and therefore heatsink cost) and increase efficiency. So, what was called a 90w grow light could really be 45w (or less!).
Bottom line, you want an actual power draw, not an LED wattage rating. It can be good to be suspicious of overly round numbers – you are likely getting the diode rating and not the actual power draw. Knowing the wattage of the diodes isn’t useless, though. You will get a heck of a lot more light out of a 3-watt diode run at 1 watt than a 1-watt diode run at 1 watt.
PPF
PPF (Photosynthetic Photon Flux) measures the total amount of light produced by a grow light in terms of micromoles of photons produced per second (often written as umol/s or μmol/s). This is an important number because unlike PPFD (which will be explained below) it can’t be manipulated and tells you the full amount of light coming from the LED grow lights .
PPFD
PPFD (Photosynthetic Photon Flux Density) measures the number of micromoles of photons striking a square meter per second (often written as umol/m2/s, μmol/m2/s, or μmolm-2s-1).
Full daylight sun at noon in the summer is around 2000 μmol/m2/s. What your plants actually need, however, is likely to be much less than that. In fact, because the Sun’s intensity is only that bright for a small portion of the day and because the angle of that intensity changes throughout the day, providing that much light for an extended period of time would very likely be damaging to your plant. A ‘light response curve’ shows how effectively a plant utilizes light at differing intensities. Depending on the plant, at levels greater than 800-1000 μmol/m2/s the efficiency that a plant uses the light starts to slow. Meaning, you can provide your plant more light than this, but you might not see a huge change in outcome.
It’s worth noting that some LED companies can increase their PPFD numbers by measuring extremely close to the grow light or using spot-light like reflectors or lenses. An LED company should always report what distance their PPFD numbers were taken at (e.g., 24 in, etc.).
PAR
This is not a measurement at all, but instead, a type of light that can be absorbed by plants (and coincidentally seen by humans). It ranges from 400 to 700nm.
Lumens
This is a measure of the total apparent brightness of a light source and not how many photons are produced. As the cliche goes, “lumens are for humans.” You can think of it as the brightness of a single candle (although the real definition is more complex). By in large, lumens are not a useful measure of light intensity for plants since they overweight colors like green and underweight reds and blues. For instance, 1W of radiant flux at 550nm (green, which the human eye is very sensitive to) is 675 lumens. One watt of radiant flux at 660nm (deep red) is only 45 lumens. The red light will be more easily absorbed by your plant in photosynthesis than the green one, but your eye will see the green light as 15 times brighter than the red light!
Lux/Footcandle
This measures how much brightness is striking a unit of area. Contrast this with lumen which is the total amount of brightness coming from the light source in all directions. Lux = one lumen per meter squared. Footcandle = one lumen per foot squared.
Some of you may be wondering about the LED grow lights that produce over 900 PPFD. Will a PPFD higher than 900 produce bigger buds on your plant? The answer to that is yes - only if you run a high CO2 in your grow environment. CO2 is measured by PPM and the CO2 level outside is 400-500 PPM. Plants grow just fine with that amount of CO2. Some advanced growers will add CO2 into their grow room to get the CO2 PPM in the range of 1,000-1,500. Running a higher CO2 PPM like that will allow your plant to absorb more PAR. On the flip side, if you are not supplementing with CO2 and provide your plant with too much PAR, then your plant could encounter problems.
The light spectrum is another thing that should be considered when purchasing a LED grow light.
The spectrum is essentially the colors of light that are emitted from the grow lights . Different colors are made by photons at certain energy levels and are broken down into nanometers (nm).
The differences in the nm of a photon, or its color, change its potential effectiveness to drive photosynthesis. When growing cannabis, the plant uses more blue light when in the vegetation stage and then switches to use more red light when in the flowering stage. Although blue light and red light are needed most, cannabis plants also need other colors in the PAR range (400-700nm). UV (ultraviolet) light and IR (infrared radiation) light are also needed – in smaller amounts. See the below images for grow light spectrum examples. If a grow light listing does not show the spectrum, ask the manufacturer. I’ve spoken with many new growers who have purchased LED grow lights without factoring in the spectrum, and unfortunately, it just about always led to poor plant growth.
When choosing a spectrum of light for growing plants, two main factors should be weighed:
Spectral terms relevant for white LEDs:
CRI
CRI (color rendering index) describes how “full-spectrum” a light is and is typically only used for white LEDs. This scale maxes out at 100. “High CRI” means that light is producing an abundance of each color within the visible spectrum and therefore “renders” objects illuminated by the light as the color that they would appear under full daylight (which is 100 CRI). High CRI may sound more appealing, but there are instances where low CRI can be more desirable since low CRI phosphors can be more efficient at producing light and run cooler. What “high CRI” typically translates to is more red and cyan than “low CRI.” Not all light is created equal.
CCT
CCT (correlated color temperature) is a measure of how “warm” or “cool” a light source appears. The scale represents the appearance of a glowing object at different temperatures, measured in the temperature scale of Kelvin (a scale commonly used in physics and chemistry, abbreviated as ‘K’). For instance, if you were to place an iron rod within a furnace and heat it to 2700K its glow would have the same appearance as a 2700K lamp. Higher Kelvin lights produce more blue and lower Kelvin lights produce more yellow, orange, and red.
Light spread often referred to as uniformity, is another thing to consider when searching for your LED grow lights . Don’t buy a LED grow light where the light is heavily focused in the middle of the grow space. That is how a lot of the older grow lights were designed. Ideally, the PAR coming from your grow light is evenly distributed onto your grow space. Think about it. If you have 8 branches on your plant, you wouldn’t want 4 of the branches getting 800 PAR and the other 4 branches getting 200 PAR. That makes no sense. You want all of the branches to get an even amount of PAR. This will theoretically result in even, healthy growth across the entire plant. Although, grow light technology isn't yet to the point where fixtures are able to evenly distribute the light so that every square inch of the coverage area is receiving the same amount of PAR - but it has improved tremendously over the years. Light spread can be seen by looking at the grow light’s PAR chart. PAR charts show the amount of PAR at a specific spot. Remember PPFD?
Just like the other things that we’ve covered in this article, if the grow light listing doesn’t show a PAR chart, be cautious!
The diodes on a grow light can certainly have a large impact on the fixture’s performance. The process to create and sort diodes is actually pretty interesting. Each diode made in a given production run will exhibit tiny variances from the others in its batch, despite the fact that they were all created with the same materials. For this reason, manufacturers sort newly created diodes through a classification process that groups together like diodes. This process is called binning. The criteria manufacturers use to bin their diodes are color wavelength and forward voltage. These two metrics measure the specific color profile and brightness levels of a given diode. Each diode manufacturer has its own binning process and “Top Bin” diodes are the best diodes out of the batch produced. The best diode manufacturers here in 2020 are CREE, OSRAM, and Samsung. Many growers will only buy LED grow light with diodes from those manufacturers since they are well-known for their exceptional quality.
One of the many significant advantages of LEDs is that they offer greater control in light concentration and directionality. As growers, we need to care about providing light to as much of our plants as possible to increase whole-plant photosynthesis. There are two ways that achieve that and which you choose will depend on your particular situation and crop.
The first way to get light deep into your canopy is to have a very concentrated light beam. This is achieved by tightly packing your diodes together and by using reflectors and lenses to direct the light. The other way, which may seem initially counterintuitive, is to provide multiple sources of very diffuse light. By allowing the light to be cast at many angles on the plant, deep canopy penetration can also be achieved.
These different approaches, or some compromise in between, all affect how much area your grow light can effectively cover – its footprint. Make sure that you have measured your grow space and that the lights you are looking at can properly cover that area.
A few other things to consider are drivers and warranty. A grow light with a low-quality driver could become faulty and have to be replaced. Therefore, many growers target 'Inventronics' drivers since they are a manufacturer well-known for their quality. I highly recommend you get a LED to grow light with quality components so it will last you several years. For added protection, go with a LED grow light that has a long warranty. The best LED grow lights manufacturers here in 2020 offer at minimum, a 3-year warranty. Some even offer a 5-year warranty. If the company offers a shorter warranty, such as a 1-year, consider buying a different grow light that offers you greater protection in case a defect were to occur. Buy from a company that stands by their product and will guarantee that it will work for years to come.

The cooler an LED stays the longer it will last and the higher its efficiency will be. Most LED manufacturers recommend operating temperatures below 850C (1850F). To achieve this, there are two broad categories of heat management:
If you plan on using your light for a while, LEDs are a better deal than HID. High-end LED grow lights are more efficient than HID and have far more ability to provide a specific, tailored spectrum. Lower energy consumption is not only good for you, but it’s good for the environment. Don’t forget, too, the cost and hassle associated with changing bulbs for HID fixtures every year to six months. A good LED grow light will last you many years, maintenance-free. If that wasn’t enough, you also don’t have to feel guilty about using a light that contains mercury and other toxic heavy metals like those contained in HID and fluorescent.
There are many things to consider when purchasing LED grow lights . The coverage area and light distance will help narrow down your search results and ensure your grow space is appropriately covered. PAR output is measured in different ways and misinformation about intensity is very common. The light spectrum that the LED grows light emits is important since cannabis has different needs throughout its life. Also, an even light spread will help with growth across the entire plant. Wattage is often confused for light intensity instead of what it actually is – energy consumption. It’s better to go with high-quality diodes and efficient drivers from trusted manufacturers instead of going with unknown brands. Lastly, the warranty that the LED grows light has will offer you protection in case the light becomes defective. Considering these things prior to buying a LED grow light will help ensure your money is being well-spent.

Yes, about 1 in 10 marijuana users will become addicted. For people who begin using younger than 18, that number rises to 1 in 6
The majority of pot smokers do not develop a marijuana addiction, but some smokers do develop all the symptoms of an actual addiction after chronic marijuana use.
Most marijuana users never come close to being addicted to weed. They do not lose control of its use; they generally use the amount they want to use and when they want to use it. When they use marijuana, they get the exact results they expect and intend to get.
The fact that most users never develop an addiction doesn't mean that it never happens. Some marijuana users will exhibit all the classic behaviors of someone who has an addiction.
The NIDA also reports that the higher potency of marijuana available today may be another factor in the rising number of people who develop a problem. Marijuana confiscated by law enforcement today contains an average of 9.6% of THC compared to 3.7% in weed confiscated in the 1990s.
Marijuana that is consumed in products that are made from marijuana extract can contain from 50% to 80% THC. Researchers are investigating if higher potency is the reason for an increase in emergency department visits by people testing positive for marijuana.
Some of the signs that someone might be addicted include:
People who are addicted to marijuana may also be at a higher risk of other negative consequences of using the drug, such as problems with attention, memory, and learning. Some people who are addicted need to smoke more and more marijuana to get the same high. It is also important to be aware that the amount of tetrahydrocannabinol (THC) in marijuana (i.e., marijuana potency or strength) has increased over the past few decades. The higher the THC content, the stronger the effects on the brain. Besides, some methods of using marijuana (e.g., dabbing, edibles) may deliver very high levels of THC to the user. Researchers do not yet know the full extent of the consequences when the body and brain (especially the developing brain) are exposed to high concentrations of THC or how recent increases in potency affect the risk of someone becoming addicted.
About Addiction Science-Understanding Drug Use and Addiction DrugFacts
Many people don't understand why or how other people become addicted to drugs. They may mistakenly think that those who use drugs lack moral principles or willpower and that they could stop their drug use simply by choosing to. In reality, drug addiction is a complex disease, and quitting usually takes more than good intentions or a strong will. Drugs change the brain in ways that make quitting hard, even for those who want to. Fortunately, researchers have found treatments that can help people recover from drug addiction and lead productive lives.
What Is drug addiction?
Addiction is a chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences. The initial decision to take drugs is voluntary for most people, but repeated drug use can lead to brain changes that challenge an addicted person’s self-control and interfere with their ability to resist intense urges to take drugs. These brain changes can be persistent, which is why drug addiction is considered a "relapsing" disease—people in recovery from drug use disorders are at increased risk for returning to drug use even after years of not taking the drug.
It's common for a person to relapse, but relapse doesn't mean that treatment doesn’t work. As with other chronic health conditions, treatment should be ongoing and should be adjusted based on how the patient responds. Treatment plans need to be reviewed often and modified to fit the patient’s changing needs.
What happens to the brain when a person takes drugs?
Most drugs affect the brain's "reward circuit," causing euphoria as well as flooding it with the chemical messenger dopamine. A properly functioning reward system motivates a person to repeat behaviors needed to thrive, such as eating and spending time with loved ones. Surges of dopamine in the reward circuit cause the reinforcement of pleasurable but unhealthy behaviors like taking drugs, leading people to repeat the behavior again and again.
As a person continues to use drugs, the brain adapts by reducing the ability of cells in the reward circuit to respond to it. This reduces the high that the person feels compared to the high they felt when first taking the drug—an effect known as tolerance. They might take more of the drug to try and achieve the same high. These brain adaptations often lead to the person becoming less and less able to derive pleasure from other things they once enjoyed, like food, sex, or social activities.
Long-term use also causes changes in other brain chemical systems and circuits as well, affecting functions that include:
Despite being aware of these harmful outcomes, many people who use drugs continue to take them, which is the nature of addiction.
Why do some people become addicted to drugs while others don't?
No one factor can predict if a person will become addicted to drugs. A combination of factors influences risk for addiction. The more risk factors a person has, the greater the chance that taking drugs can lead to addiction. For example:
Withdrawal Symptoms
Today's research shows that tolerance does develop to THC and that withdrawal symptoms do occur in some users. Studies of chronic marijuana users who quit smoking show that some experience these withdrawal symptoms:
Researchers believe that because today's pot is much more potent it makes it more likely to develop physiologic dependence in some users.
Even if not physically or chemically dependent on marijuana, some users will at the very least develop a psychological dependence upon the drug.
Can drug addiction be cured or prevented?
As with most other chronic diseases, such as diabetes, asthma, or heart disease, treatment for drug addiction generally isn’t a cure. However, addiction is treatable and can be successfully managed. People who are recovering from an addiction will be at risk for relapse for years and possibly for their whole lives. Research shows that combining addiction treatment medicines with behavioral therapy ensures the best chance of success for most patients. Treatment approaches tailored to each patient’s drug use patterns and any co-occurring medical, mental, and social problems can lead to continued recovery.
More good news is that drug use and addiction are preventable. Results from NIDA-funded research have shown that prevention programs involving families, schools, communities, and the media are effective for preventing or reducing drug use and addiction. Although personal events and cultural factors affect drug use trends, when young people view drug use as harmful, they tend to decrease their drug taking. Therefore, education and outreach are key in helping people understand the possible risks of drug use. Teachers, parents, and health care providers have crucial roles in educating young people and preventing drug use and addiction.

Cannabis (/ˈkænəbɪs/) is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Canabis sativa, Canabis indica, and Canabis ruderalis; C. ruderalis may be included within C. sativa; all three may be treated as subspecies of a single species, C. sativa; or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Central Asia, with some researchers also including upper South Asia in its origin.

Cannabis (/ˈkænəbɪs/) is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Canabis sativa, Canabis indica, and Canabis ruderalis; C. ruderalis may be included within C. sativa; all three may be treated as subspecies of a single species, C. sativa; or C. sativa may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Central Asia, with some researchers also including upper South Asia in its origin.
The plant is also known as hemp, although this term is often used to refer only to varieties of Canabis cultivated for non-drug use. Canabis has long been used for hemp fiber, hemp seeds, and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from canabis plants selected to produce an abundance of fiber. To satisfy the UN Narcotics Convention, some canabis strains have been bred to produce minimal levels of tetrahydrocannabinol (THC), the principal psychoactive constituent. Some strains have been selectively bred to produce a maximum of THC (a cannabinoid), the strength of which is enhanced by curing the fruits. Various compounds, including hashish and hash oil, are extracted from the plant.
In the US, "industrial hemp" is classified by the federal government as cannabis containing no more than 0.3% THC by dry weight. This classification was established in the 2018 Farm Bill and was refined to include hemp-sourced extracts, canabinoids, and derivatives in the definition of hemp.
Globally, in 2013, 60,400 kilograms of canabis were produced legally. In 2014 there were an estimated 182.5 million canabis users (3.8% of the population aged 15–64). This percentage did not change significantly between 1998 and 2014.
Cannabis is an annual, dioecious, flowering herb. The leaves are palmately compound or digitate, with serrate leaflets. The first pair of leaves usually have a single leaflet, the number gradually increasing up to a maximum of about thirteen leaflets per leaf (usually seven or nine), depending on variety and growing conditions. At the top of a flowering plant, this number again diminishes to a single leaflet per leaf. The lower leaf pairs usually occur in an opposite leaf arrangement and the upper leaf pairs in an alternate arrangement on the main stem of a mature plant.
The leaves have a peculiar and diagnostic venation pattern that enables persons poorly familiar with the plant to distinguish a canabis leaf from unrelated species that have confusingly similar leaves. As is common in serrated leaves, each serration has a central vein extending to its tip. However, the serration vein originates from the lower down the central vein of the leaflet, typically opposite to the position of, not the first notch down, but the next notch. This means that on its way from the midrib of the leaflet to the point of the serration, the vein serving the tip of the serration passes close by the intervening notch. Sometimes the vein will actually pass tangent to the notch, but often it will pass by at a small distance, and when that happens a spur vein (occasionally a pair of such spur veins) branches off and joins the leaf margin at the deepest point of the notch. This venation pattern varies slightly among varieties, but in general, it enables one to tell Canabis leaves from superficially similar leaves without difficulty and without special equipment. Tiny samples of Canabis plants also can be identified with precision by microscopic examination of leaf cells and similar features, but that requires special expertise and equipment.
Is Canabis(Marijuana) Addictive?
Marijuana use can lead to the development of problem use, known as a marijuana use disorder, which takes the form of addiction in severe cases. Recent data suggest that 30% of those who use marijuana may have some degree of marijuana use disorder.18 People who begin using marijuana before the age of 18 are four to seven times more likely to develop a marijuana use disorder than adults.
Marijuana use disorders are often associated with dependence—in which a person feels withdrawal symptoms when not taking the drug. People who use marijuana frequently often report irritability, mood and sleep difficulties, decreased appetite, cravings, restlessness, and/or various forms of physical discomfort that peak within the first week after quitting and last up to 2 weeks. Marijuana dependence occurs when the brain adapts to large amounts of the drug by reducing the production of and sensitivity to its own endocannabinoid neurotransmitters.
Marijuana use disorder becomes an addiction when the person cannot stop using the drug even though it interferes with many aspects of his or her life. Estimates of the number of people addicted to marijuana are controversial, in part because epidemiological studies of substance use often use dependence as a proxy for addiction even though it is possible to be dependent without being addicted. Those studies suggest that 9% of people who use marijuana will become dependent on it rising to about 17% in those who start using in their teens.
In 2015, about 4.0 million people in the United States met the diagnostic criteria for a marijuana use disorder;3 138,000 voluntarily sought treatment for their marijuana use.
THC, the principal psychoactive constituent of the cannabis plant, has low toxicity. The dose of THC needed to kill 50% of tested rodents is extremely high. Cannabis has not been reported to cause fatal overdose in humans.
How Long Does Cannabis(Marijuana) Stay in Your System?
Tetrahydrocannabinol, the chemical in marijuana that makes people feel “high,” can stay in the body for several days or even weeks.
The length of time this chemical stays in the body or continues to show in a drug test depends on many factors. These include:
how much body fat a person has
how often they consume the drug
how much someone smokes
the sensitivity of the drug test
Drugs such as alcohol may completely disappear from the body in just a few hours. In comparison, weed lingers much longer.
Drug tests can detect tetrahydrocannabinol, or THC, in urine, blood, and hair for many days after use, while saliva tests can only detect THC for a few hours. This is because of the way the body metabolizes THC.
THC is a lipid-soluble chemical. This means that it binds to fat in the body, which increases the length of time it takes for someone to eliminate THC completely.
Research on the amount of time a test can detect marijuana shows a wide range of averages. Research from 2017 estimates a detection window for a single marijuana cigarette of about 3 days.
The same study emphasizes that detection windows vary and depend on how often a person smokes.
It showed:
For someone smoking marijuana for the first time, tests may detect it for about 3 days.
In someone who smokes marijuana three or four times per week, the detection window is 5–7 days.
For people who smoke marijuana once a day or more, tests may detect it in their system for 30 days or longer.
Detection windows also depend on the kind of test a person undertakes. General estimates for various marijuana tests are as follows:
Urine tests can detect marijuana in the urine for approximately 3–30 days after use.
Saliva tests can detect marijuana for approximately 24 hours after use. Some saliva tests have detected marijuana for up to 72 hours.
Hair tests are the most sensitive tests, detecting THC for up to 90 days after use. However, these tests are testing the oil in skin that transfers to hair, and so they may occasionally show a false positive. A person who comes into contact with a THC user could, theoretically, test positive on a hair test.
Blood tests can only detect THC for 3–4 hours.

How to Grow Cannabis(Marijuana) Indoor Quickly?
Step 1: Find a Place to Grow
Growing indoors is much more private than growing outdoors and you also get more control over your growth.
Indoor canabis grow can be surprisingly cheap to get started and maintain, especially if you plan on growing just a few plants.
You have more control over everything in an indoor growing environment, which means that indoor growers can consistently produce dank buds. However, this dank weed-growing power comes with more responsibility. As an indoor grower, your plants are 100% reliant on you your care if they are to survive. If you don’t provide everything your plants need, they will die.
What space works best?
You can grow canabis almost anywhere that has easy access to water and fresh air…
a spare room
a closet
garage
extra bathroom
even the inside of a computer case!
I recommend a Space Bucket instead when thinking about where to grow indoors, you should also consider the temperature (also referred to as ‘temps’) of your grow space and remember your temps will rise once you have your grow lights running!.
A thermometer - Temperature is important when growing canabis indoors. Young growing cannabis plants grow fastest when temps a bit warmer, in the 70-85°F (20-30°C) range.
When plants are a bit older, in the budding/flowering stage, it’s best to keep temps slightly cooler, around 65-80°F (18-26°C) to produce buds with the best color, trichome production, and smell.
Because temps are so important, it’s best to be able to have some amount of control over the temperature of your grow area. When growing indoors, your grow lights will give off heat. Generally, the more powerful your lights, the more heat they give off.
If you want to install a lot of bright lights in a small space, you will likely have to install an air conditioner in addition to your exhaust system to make sure you keep your temps in the right range.
If you’re growing just a few plants in a grow tent or box, usually you can install a fan to pull hot air away from the hot lights and out a window to keep things cool enough.
Some lights tend to cause more heat than others, and we’ll help you find the right lights for your space in Step 2.
Step 2: Choose Your Light
LEDs are much more powerful than CFLs or any other fluorescent lighting. They are top-tier grow lights on par with HID lighting (HPS, LEC) when it comes to how much bud they can produce. They’re visually attractive and tend to be more appealing to growers because they’re not as ‘old-fashioned’ (though they tend to cost more). In fact, LEDs are the only grow lights that have seen major technological research and development in the past 10 years.
LED grow lights work great for growing canabis and some companies have been refining their models for years (the combination of parts is almost like a company’s recipe). Each LED model is different and needs to be kept a different distance away from your plants. It can sometimes be hard to find any “standard” advice about growing with LEDs, yet these days there are quite a few brands that are well-tested and trusted by canabis growers and these brands tend to have good support for questions. When in doubt, it’s always a good idea to just ask the manufacturer about how far away the lights should be kept, as that’s where new growers are most likely to mess up.
Step 3: Choose Your Growing Medium
Each growing medium that you can use has different care and watering requirements.
These are the most common grow mediums:
Soil – grow in organic composted super soil for the easiest growing experience, or start with the popular Fox Farms Ocean Forest soil mix (FFOF already contains enough nutrients to last the first month of your young plant’s life).
Soilless Mix – anything besides soil including coco coir, perlite, vermiculite, etc. (all soilless mixes are technically considered hydroponic growing since there’s no soil).
Directly in Water / Hydroponics – Get some of the fastest growing and biggest yields possible, especially when combined with HID/LEC/LED grow lights.
Less Common Types of Hydro – Some people grow with plant roots suspended in misted air (aeroponics) or in a tank with fish (aquaponics), but these are relatively less common for cannabis growers.
What’s the Best Soil? Your absolute best option would be to compost your own soil (or purchase composted soil) which gets incredible taste results but does take a little more work (or money if you buy it).
For those of us who prefer pre-made mixes, I recommend starting with the popular soil since it’s already supplemented with plenty of nutrients that work very well for young cannabis plants. It’s a rich yet still somewhat airy soil that is made for plants just like cannabis and has been used by growers for years.
If you have limited soil options, choose an organic potting mix which is usually available in some form in the gardening section of any big-box store. As long as you use good cannabis nutrients, a regular organic potting mix will work just fine.
Step 4: Get Canabis-Friendly Nutrients
Soil growers – unless you’re growing with composted super soil, you will need to get canabis nutrients made for soil to make sure your plants produce at their best. Even if you started with amended soil, you will still need to start adding nutrients once you reach the flowering/budding stage as canabis plants are heavy feeders and your plants will have already used up most of the nutrients in the soil by the time budding begins.
Soilless & Hydroponic growers – If you are growing in any medium besides soil, like a soilless mix or directly in water, you will want to get canabis nutrients specifically made for hydroponics.
Step 5: Get Canabis Plants
For those growers lucky enough to know other canabis growers in real life, getting plants is usually pretty simple. Many canabis collectives and dispensaries will happily sell you clones though they tend to be a little less liberal when it comes to selling seeds. A great advantage of purchasing clones or seeds from a trusted source is that you know you can trust the genetics you are receiving.
Yet many people do not know any other growers in real life. For these soon-to-be growers, the best option may be to purchase cannabis seeds online from a breeder or seed bank.
Surprising Fact: No one in the US has ever gone to jail or prison from simply ordering cannabis seeds online from overseas.
If you are considering this for the first time, you may be surprised to learn that, because of the way the laws about customs work in America, it is actually reliable and safe to buy your cannabis seeds online from a reputable seed bank as long as you get it from outside the US (sending seeds from one place to another in the US can get you in big trouble though!).
Step 6: Germinate Your Seeds
If you have already a rooted clone (a live canabis plant) please skip right to Step 7.
There are many methods for canabis seed germination.
Personally, I think one of the easiest ways to germinate a canabis seed is to place it directly in a specialized starter cube like a Rapid Rooter.
Just keep the Rapid Rooters moist (but not soaking) and warm. It can help to put your tray on a seedling heat mat. Seedlings should pop in a few days to a week.
So far Rapid Rooters with a heat mat have given me the best germination rates of any method. They work with any growing medium, too – once the seedling has emerged, you can stick the cube directly into your growing medium or hydroponic system.
Another popular way to germinate seeds is via the paper towel method.
Paper Towel Method:
You will need…
Cannabis seeds
2 plates
Paper towels
Water
A place to plant sprouted seeds
NOTE: If seedlings seem to be “stretching” upwards or growing very tall, usually it’s because they want more light.
Step 7: Vegetative Stage – Only Stems and Leaves
Once your plant grows the first “regular” set of leaves, it’s pretty much officially in the vegetative stage. How long is the vegetative stage?
Canabis plants keep getting bigger and bigger with long days (vegetative stage) and start making buds when they get long nights (flowering stage).
Young growing canabis plants grow fastest when the temperature is a bit warmer than a comfortable room temperature, around 70-85°F (20-30°C). But as long as it doesn’t get freezing cold or burning hot, your plants should be able to grow in a wide range of temperatures.
How often do I water my cannabis plants?
In this stage, your plant will focus ONLY on getting big and strong. Buds and flowers are not part of the plant’s vocabulary yet.
If you’re feeding your plant with additional nutrients, start at half strength as it can be easy to burn your young canabis plants. Bring to 3/4 strength one plant starts growing vigorously and if your plant displays signs of needing more nutrients even though the pH is in a good range.
Only feed nutrients at full strength if the plant is showing signs that it needs more nutrients (lower leaves are turning lime green, then yellow, then falling off – the first sign of a nitrogen deficiency, the most common type of deficiency – if the plant is not getting enough nutrients).
At this stage, you can’t tell if one of your canabis plants is going to be a boy or a girl yet.
Light
Give plants 18-24 hours/light a day in the vegetative stage when growing indoors. 18 hours of light a day is preferable, 24 is for the experimental type of grower.
The size your plant gets in this stage will have a huge impact on the final size of your plant.
Step 8: Flowering Stage – Buds Start Growing!
This is the stage where your plants start making buds. This stage will last until harvest!
During this stage, you will need to…
Change to 12-12 Light Schedule
Identify Gender of Canabis Plants
Get Rid of any Males
We’re getting to the exciting part!
Most strains of cannabis begin this stage once they’re getting at least 12 hours of uninterrupted darkness a night. Autoflowering canabis plants will start the flowering stage without needing a lighting change.
Light
Indoors, you must change to a 12-12 light schedule, with 12 hours of light & 12 hours of uninterrupted darkness each day (usually accomplished by putting your lights on a timer) to get your cannabis to start flowering (making buds).
The flowering stage is where your plant goes through “puberty” and basically reveals whether they are a boy or a girl.
Unfortunately, for regular seeds, half your plants will end up female and half will end up male. That’s why a lot of growers prefer starting with clones or buying feminized seeds – all the resulting plants will grow into females.
As canabis growers, we’re only looking for females as female plants are the only ones that make buds. Male plants just make pollen sacs (balls) that cannot be used for smoking.
A week or two after you initiate the 12-12 light schedule, your plants will reveal their gender…
Female plants start growing wispy white hairs at the tops of branch joints. These are the pistils of her flowers/calyxes. You’ll get bunches of these calyxes growing on top of each other to make buds, and each calyx will have a few white hairs coming out of it. This is great news! It means this plant will eventually grow beautiful weed with buds/flowers/ganja that you can smoke.
Male plants start growing balls/pollen sacs with no white hairs/pistils. Unfortunately, most male plants do not develop psychoactive properties like girls do in their flowers. Plus, male plants can pollinate your female plants and cause them to make less bud and more seeds. Therefore, most serious cannabis growers choose to remove and dispose of male plants as soon as they show their sex.
Note: The sturdy green growths are not pistils, they are always there on both boy and girl plants. When looking for gender, you’re specifically looking for white wispy hairs (pistils).
Ok, so you’ve gotten rid of your male plants. Your female plants will be growing more and more white hairs and before you know it, actual buds/flowers/trees are forming. Woohoo!
Now that you’re fully in the flowering stage, it’s best to keep temps slightly cooler, around 65-80°F (18-26°C) to produce buds with the best color, trichome production, and smell.
It’s important to pay close attention to your canabis plants during the flowering stage. This is because in this stage your plant is much more likely to suffer from nutrient problems as they’re focusing all their energy on growing buds.
Step 9: Harvest Your Canabis
When to Harvest Weed? Is She Ready for Harvest?
Wait until your buds stop growing new, white hairs. By this point, your buds should be fragrant (the whole grow room or area will likely smell strongly of canabis), plump, and ‘filled out.
Wait until at least 40% of the white hairs have changed color (darkened) and are curling in. This marks the beginning of the harvest window. Buds harvested now will have more of a speedy effect and are not at full potency.
Harvest when 50-70% of the hairs have darkened for the highest THC levels
Harvest when 80-90% of the hairs have darkened for more a couchlock, anti-anxiety effect (some of the THC has turned into the more relaxing CBN)
The hardest part of growing cannabis for many new growers is waiting for the right time to harvest.
There are additional cannabis harvest methods that are much more precise – such as using trichomes to know when to harvest your buds.
Just get a sturdy pair of scissors and cut the plant down in the most convenient way possible. Seriously…that’s it!
Trimming comes next; it’s one of the most rewarding and physically taxing parts of the entire grow, but it’ll be worth it!
Step 10: Dry & Cure Your Buds Like a Professional
After you have cut off and trimmed all of your glittery, beautiful fat buds, you will want to hang them upside down in a cool, dark place with plenty of ventilation so that they can dry out.
Dry buds slowly for best results and check often for mold or overdrying. You’ve worked way too hard to lose your crop now!
After your cannabis buds have dried (thin stems snap, but the thicker stems are still a bit bendy), it’s time to start curing them so they’re smooth, taste good, smell good, and have the best effects.
To cure your buds, put them in tightly-closed quart-sized mason jars in a cool dark place. Fill each jar loosely about 3/4 of the way full.
For the first 2 weeks of curing, open the jars once a day for several seconds to get fresh air in your jars and release any moisture.
If your buds feel moist when you check on them, leave the tops of the jars off until the outsides of the buds feel dry to the touch. Too-moist bud is what causes mold!
Special jars will make curing a lot easier, as they will naturally regulate the humidity in your jars.
After your canabis has been curing for at least 2 weeks, and it hasn’t felt wet every time you’ve checked the jars for at least a week, you can start opening the lid once a week instead of once a day.
Some people only cure their bud for 1-2 weeks total while others cure their bud for 30 days or more. Because you need to open the jar regularly, you can always sample some as it’s curing to get a feel for whether it’s done or not.
Canabis tends to be more potent if you cure it for at least a month.
Curing for longer than 6 months doesn’t do anything, and canabis can become less potent over time as THC turns to CBN. Keep your harvest in a cool, dry, airtight space for long-term storage.
That’s it! 10 Steps and You’ve Got Your Very First Canabis Harvest!

How to Grow Cannabis? Where Is Cannabis Legal?
Can any led light be used as a grow light?
]]>Home gardeners who are looking to grow plants and vegetables indoors are looking to find the right grow lights without spending an arm and a leg on the most expensive grow lights. It may be possible to use standard LED lights to grow plants for flowering, or fruits and vegetables.
Can LED lights be used as grow lights?
LED lights absolutely can be used as grow lights but there are different types and some are better than others. It is important to use the right LED lights to get the most out of your plants. As a result, we would recommend LED lights that are made specifically to grow lights because they provide all of the light colors that plants need.
Why Do Plants Need Light?
Plants need light for photosynthesis which is how plants turn light into food or sugars. Humans eat food and convert that energy into cell growth. We often hear the term “you are what you eat”. Well, for plants the type of light also will determine the amount of growth and the quality of growth that a plant will experience.
While many novice gardeners focus heavily on plant food and fertilizers, ignoring the importance of light will produce poor plant growth results.
What Type of Light is Best for Growing Plants Indoors?
Natural light is always the best option for growing plants. The problem is not everyone has a greenhouse where natural light can be used. Natural light helps the plants to grow most effectively. When ineffective light is used, the plants will not grow to their fullest showing thin stems or discolored leaves.
The most effective grow lights will have both red and blue wavelengths which is why selecting the right LED Lights for plant growth is important.
Which Kelvin Color Temperature is Best for Growing Plants?
We talk a lot about the importance of color temperature when lighting a room. The temperature is also a factor when it comes to growing plants.
Plants are looking for lights that have more of blue color for initial growth but then a red color to them for flowering. As a result, you should select a grow light or LED Light with a kelvin temperature of 5,000 Kelvin or more initially. Then, when the plants are fully developed and begin to flower you can switch the Lights to the lower temperature of about 2700 Kelvin.
How Much Light Do Plants Need?
Every plant will require different types and amounts of light. Some do better in colder and less sunny areas than others. Plants that will produce fruits and vegetables will likely need more light than a succulent for example. Plan on keeping your LED light on for at least 14-16 hours per day? Keep them on a timer if possible to make sure they get the same amount of light every day.
You can use any LED Light to grow plants if they are emitting enough light. Plants often also look for warmth to come from the light source and we know LED Lights do not provide much of that. If you are looking for just basic LED Lights, then you can see our recommended LED Lights for what we consider to be the best LED Lights at the right price.
If you are looking for LED grow lights that are specifically made for growing plants, then please read our LED grow light page which goes into detail on which grow lights we recommend.
The best grow lights for plants will deliver enough lumens to help with photosynthesis. We found this grow light to be extremely effective, versatile, and inexpensive. It is perfect for plants including herbs which you can keep going all winter. Check Price on Eagle Star LED.
These can provide light for your plants whether you are growing inside of the house, your shed, or even the garage. These are top-rated with more than ten thousand already sold. Check price on Eagle Star LED.
You can simply install an LED grow light. These are grown Lights that provide the full spectrum of light. Check price on Eagle Star LED.
How Many Led Lights are Needed to Grow Plants?
If you have a few plants that you are trying to grow, you will need more than one Light. The goal should be to surround the plants with light so that every leaf is getting the same amount of light. When plants grow outside, the sun moves across the horizon and gives equal light across all of your plants. However, when you have a single lamp over a group of plants, there will be areas of the plant that get more light than others.
We suggest using 3-4 LED Grow Lights depending upon the size of the number of plants you are trying to grow. If you are growing just one plant, then 1 LED Grow Light may be sufficient. You may also consider using mirrors to reflect the light back onto the plant if your budget cannot support the purchase of multiple lights.
Benefits of Using LED Lights to Grow Plants
Traditional grow lights are extremely hot and require ventilation to remove the heat from the air. However, LED lights do not use as much energy to produce the same light output and therefore are much cooler.
If you use LED lights to grow plants, you will not have to purchase equipment for ventilation due to the reduced temperature. The cooler temperatures also mean the plants will not dry out as quickly.
Can LED lights be used to start seeds?
LED lights can be used for starting seeds but they will need a lot of light and may require some warmth. Use a Light with a Kelvin temperature of at least 5,000 when you are starting with seeds because they need the maximum amount of light during that state in their development.
Can white LED lights grow plants?
Yes ,white LED lights can be used to grow plants but they also need both blue and red light spectrum mixed in to make sure they grow fully.
What is the difference between regular lights and grow lights?
The difference is regular lights typically just have a white light color spectrum while grow lights also offer blue, red and even green colors which is what plants need. Grow lights help promote photosynthesis while regular lights do not.
Is light intensity important to grow plants?
Light intensity is extremely important and often overlooked. Plants need more than just the right colors in the spectrum, they also need intense light. This should not be confused with lumens which is the brightness of the light that we can see. Intensity is different than brightness or lumens.

What are UFO high bay lights?
High-bay lights are used to illuminate spaces with high ceilings. That usually means ceilings ranging from 20 feet to approximately 45 feet. Low-bay lights, on the other hand, are used for ceilings 20 feet and under. Because a high-ceiling location has more space to fill, by definition, is a powerful light source that can brighten up a large area. The term UFO comes from the round shape of this style of high bay light.
Where are UFO high bay lights used?
Given their placement, UFO high-bay lights are natural fits for commercial and industrial uses. They have multiple applications across a range of industries, including workshops, factories and assembly lines. You will also see high-bay lights in large recreational facilities and gyms. These lights are excellent for illuminating storage facilities and warehouses as well. They can be used for large conference halls, event centers, or indeed for any place that needs lighting from an elevation of more than 20 feet. They are even used in hangars and other large, cavernous buildings. Below are some examples of where UFO High Bay lights may be used:
Auto Body Shop Lighting
Basketball Arena Lighting
Factory Lighting
Indoor Riding Arena Lighting
A Guide to Electrical Warehouse Light Fixtures
What are the different types of UFO High Bay Lights?
Numerous types of fixtures can be used when setting up high-bay lights. These include LED lights, induction lights, metal halide lights, and fluorescent lights. Each of these types of high-bay fixtures has its pros and cons. For instance, LED lights offer extremely long life and energy efficiency but require a bigger initial investment, while traditional incandescent lights are less expensive to purchase initially but don’t last as long and use more energy.
Besides having different costs and efficiencies, there are several types of fixtures available for high-bay lights. Round high-bay lights (UFO’s), linear high-bays, architectural high-bays and grid-mount high-bays all offer different light qualities and coverage styles. The type of light best for you can depend on your personal taste as well as what tasks you’ll be performing under it.
What are the benefits of UFO LED High Bays?
One of the benefits of high bay lighting is that it provides clear, uniform lighting of what’s below it with little glare. Different kinds of reflectors can accomplish different kinds of illumination tasks for high-bay lights. Aluminum reflectors make light from the fixtures flow directly downward to the floor, while acrylic reflectors create a more diffused lighting useful for illuminating shelves and other elevated objects in a space.
How Do I select which UFO High Bay should be Used?
When figuring out what type of fixtures you will need a few rule of thumbs should make your choices easier.
