Uv light cannabis

I’ve been working with UV over 27 years, with half of that being directly with cannabis growers, including some rather famous ones you’ve heard of and perhaps have bought a book or two from. We have a network of hundreds of growers, dozens of testers, and a couple of different labs we work from. I don’t know much, but I know UV.

I get on Facebook and other social media and I find that most people talking about UV simply have bad information. They just don’t understand it. Some of them are convinced they do, and a rare few think they are experts because they have a year’s experience with it. Most people just read bad information that keeps getting passed around as if it is gospel, when in fact, the information is false. This page is designed to bust some of those myths, from someone who actually is an expert on UV. I try to keep it light, and just deal with one issue at a time.

You only need UV light for the last 2/3/4 weeks of flowering

Not exactly. You can use UVB (UVA is much less helpful in this situation) only in the last few weeks and yes, it will be better than if you didn’t, but you are missing out on the true potential of UVA/B. In the wild, plants don’t get UV just in the last 2 to 4 weeks. In fact, they get much LESS UV during the last month of flowering than they do during veg simply because of the angle of the sun. Plants will absolutely produce more trichomes, more THC if you use a proper UVB bulb during the entire flowering season. In fact, most larger, successful growers will run them an hour a day during the last half of veg to harden them, and to kill off any risk of powdery mildew.

I don’t need UV, my LED system (or CMH or MH) already has it

Your LED has 365nm and higher, not UVB. Also, it has a very low amount of UVA at 365nm. I’m sure it is helpful, but 365nm will NOT increase trichome production. Only 280nm-320nm does that, and 280-290nm in particular. This is why our Flower Power does a better job than our Universal UV. The Universal is similar to other lamps on the market and does a good job but doesn’t produce 280-290nm. The Flower Power does product 280nm+ and smokes everything else because of it. So while your LEDs have a little UVA, they are missing out of the most important part of the UV spectrum; high frequency UVB, and THAT is where trichrome production is triggered.

I can’t run your UV bulbs, I’m using LED / HPS / MH / whatever

You can run Flower Power bulbs with any general lighting. They won’t interfere because they produce virtually zero visible light. They pick up where your general lighting leaves off, around 400nm. No matter what general lighting you use, they will work and do the same great job.

All you need is a reptile bulb

Technically, you don’t NEED anything, but a reptile bulb is pretty mild and won’t get dramatic results. The problem is that the majority of the output from a reptile bulb is actually NOT ultraviolet, but it is visible light. This doesn’t help you, and in fact, interferes with your color temperature if you run a tight setup. To compare, a Flower Power bulb is going to be about 20 times stronger in he UVB region. This is why you only use them for 2 hours a day, and why they work. To get the most of the plant, you have to hammer it for a short while, then let it rest for the bulk of the day. Otherwise, you aren’t really stressing it, and you won’t get the high trichome production.

All UVB lamps are pretty much the same

Very wrong for a variety of reasons. For starters, UVB isn’t a singular thing. It is a range of colors that span 280nm to 320nm. Virtually all UVB bulbs only produce only the lower energy portion of that spectrum, 300-320nm. The Flower Power is the exception, because it uses a patented glass. The higher bands from 280-290nm in particular are exponentially more powerful and where you get a real defense reaction from the plant.

As long as you give it some kind of UVB, you are going to get the same results

Basic plant biology says otherwise. The protein that tells cannabis (and other plants) that they are in a high UVB environment is called UVR8. Triggering this protein is what makes the plant go into overdrive and produce tons of extra trichomes. The only way this is triggered is by exposure to 280-290nm. The overwhelming majority of UVB lamps do not produce this range. The Flower Power does.

UV will damage the plants and give you cancer

I get this one every now and then. Plants evolved in the sun, where there is UV, so did humans. The key is using the right UV, for the right amount of time, and not overexposing the plants (or yourself). It’s simply not worth debating, the science is utterly clear that humans and plants both benefit from moderate amounts of UV.

UV will interfere with my lights

Any good, pure UV light (meaning it has zero visible phosphors) will not. This includes the Universal UV, the Super B and the Flower Power. They produce almost zero visible light. In fact, it’s kind of hard to tell if they are on unless you look at them directly. Since virtually all their energy is 400nm and below, they will not interfere with your visible light, which is 400nm to 700nm, and obviously they won’t interfere with any infrared you have. Lights that mix UV and visible light (reptile lights, for example), WILL change the color temperature in the room.

I tried reptile lights, but they didn’t kill powdery mildew, so UV won’t kill PM

Illogical leap of logic. Reptile lights are weak, on purpose. Flower Power bulbs are 20x stronger in the UVB region, and many times stronger in the UVA. Both high UVA and UVB help kill powdery mildew. We have hundreds of users that use them solely for that purpose. The key is adding UV before you have a huge problem. Used regularly, you will find PM is a thing of the past. The extreme intensity is why they work. For treating PM, you need to run two hours continuously per day, no breaking up the time. Hammer it hard and heavy and in all but the most messed up situations, it will kill it.

You don’t need UVB to grow great cannabis

True and false. Obviously you can grow great cannabis without adding UVB, underground growers have done it for years. But if you take that same grow situation and add the right amount of Flower Power, you are guaranteed to increase THC by at least 15% (for example, going from 17% to almost 20%) and many experienced growers are getting 25% (going from 22% to 29%) or even more. Some growers are reporting total THC of 30-35%. It is very difficult to achieve those numbers without very good UVB.

Adding UVB will reduce your yields

True and false. If you use Flower Power for two hours a day, you will find your yields are exactly the same as without them, except a larger ratio will be THC. If you work your plants up to 4 or 5 hours a day (most growers don’t try this), then yes, it start cutting yields by 5-15% but it boosts THC dramatically. For 99% of our customers, we recommend you stick with the 2 hours a day, get the same yields, get more THC, and keep it simple.

It’s too expensive

It isn’t free, but do the math: A $40 bulb will at LEAST 4 plants for 3 flowering seasons. That is a minimum. Lets keep the math simple: That means 4×3=12 plants will benefit from that bulb. Cost per plant is $3.33. If it increases just a MINIMUM of 15% more THC, you’ve paid for the bulb before the first harvest. If you get the average gain, 20% higher THC (really it is 25%, but let’s err on the safe side), and you get 12oz from each plant (a low minimum), that means the 144oz that you harvest will go from 20% THC to 24% THC. Or from 25% THC to 30% THC. Guaranteed. Is that worth $3.33 a plant? Plus, don’t forget, you’re also getting the mold and mildew suppression and insect suppression. In reality, Flower Power are very, very inexpensive. Not using them is expensive.

Any UVB is better than none

Actually, this one is true. Even a cheap UVB bulb is better than no UVB. That said, for a little more than a cheap UVB bulb, you can have the best UVB around, and since Flower Power last twice as long, they really aren’t more expensive. So use what you have, but make room to upgrade later if you really want top shelf results.

Cluster of female cannabis flowers You’ve probably found yourself here because you’ve heard that ultraviolet might increase the potency of cannabis. You might have also have heard some people say it isn’t true, and you are curious as to whether or not it really does. The purpose of this article is provide you some information, and some citations demonstrating the concept and why it really works and works extremely well if you do it right. The science behind the idea dates back to the 1980s and perhaps earlier, so this is a summary of that research. Much of this might be a bit of an oversimplification, but the goal is to give you an overview of why proper UV works, it isn’t to be a science class.

When we talk about ultraviolet and increased potency in cannabis, we are singularly talking about THC (Tetrahydrocannabinol) production. The effect of UV on the other 84+ cannabinoids isn’t fully known, nor has it been studied in detail. One would assume that if you increase the amount of THC, you are probably lowerin the amount of other cannabinoids (in particular, CBD or Cannabidiol), but this is just conjecture and the adecdotal evidence is conficting. Growers who are trying to produce marijuana that is moderate or low in THC but high in CBD would actually want to avoid ultraviolet, which explains why it is always grown in greenhouses (whose glass filters out all of the UVB and most of the UVA). Most growers, however, are wanting to grow cannabis that is high in THC, whether it is for medicinal use or recreational use. This article applies to them.

Understanding the plant

Most plants on the planet have both male and female flowers, making them hermaphrodites (monoecious). Cannabis is one of the rare plants that has individual genders, both male and female plants (dioecious [4] ), although some plants will have both male and female flowers. The female is the grower’s target, and growing largest and most potent flowers (buds) is the goal. To this end, all males are removed, to prevent the female from going to seed. The key is, no one has told the female that she will never be pollenated. As far as the female plant is concerned, her flowers/buds are the bed for her children (seeds) and she simply hasn’t been pollenated yet. Her seeds are the only way she can reproduce, and reproducing is the primary purpose of every plant. As such, she will protect that flower as if it has her children in it, even before it does. Like most plants, cannabis has built in protection mechanisms to guarantee the next generations, which takes us to THC.

That THC is psychoactive is perhaps an accident. This quality hasn’t necessarily benefitted the plant, except those qualities has insured that man has cultivated the plant for thousands of years. THC has a biological role for the female plant that is critical for you to understand: THC has very high UVB absorption rates, meaning it is like sunblock for the plant. [1][2][3]

Ultraviolet

The ultraviolet spectrum is broken into three bands. They are actually “colors”, we just can’t see them. Like colors, there is a range within each color. This is how “pink” and “burgandy” are both types of red, just different parts of the red spectrum. The same for ultraviolet. If you look at a rainbow, you see the colors go from deep red (wavelength of 700nm) all the way to violet (400nm). The next color is UVA (320nm-400nm), then UVB (280nm-320nm) and finally UVC (10nm-280nm or 100nm-280nm, depending on who you ask). UVC is used for water purification and such because it kills organisms. It can also give you a flash burn in a few seconds, so fortunately, the atmosphere filters out almost all of it. When a plant is outside, they get a fair amount of UVA and UVB, typically in a ratio that is around 5% UVB and 95% UVA. They have evolved over millenia to adapt to this and survive. In the case of cannabis, the plant developed THC to protect the next generation. The more UV it is exposed to (to a point), the more THC it will produce.

When we moved growing cannabis to the indoors and in greenhouses, we did remove a lot of dangers to the plant: wind, soaking rains, animals, most insects and more. This increased the yield by 100% or more. The problem is that high pressure sodium (HPS) has zero UV of any kind. Metal halides have .5%, which is a negligible amount. The plants grow well, they are large, thick, robust and even potent, but they are far below their potential because we made their environment TOO perfect. Without the stress of UV, they have no need to shift resources into producing high amounts of THC. Instead, they produce a default amount, programmed by their DNA.

The process

In order to increase the THC, you need to understand that plants aren’t lazy. They spend all their time doing something: growing tall, growing buds, creating THC, moving nutrients around and such. When you introduce the proper spectrum of UV to the plant, you are forcing it to shift its resources into protecting itself. It will spend a little less time growing sun leaves, sugar leaves and even the buds will be more dense and just a hair smaller, but it will produce a lot more THC. Since THC is the ultimate goal, the market potential is significantly higher for plants grown with proper UV. It short, it makes you a LOT more money.

Using proper UV can cost you $5 to $10 per plant when you average out the cost of lights and fixtures. It is very cheap. Most people are able to get increases of 20% THC the first time they use it. Most experienced growers are getting over 30% more THC than with clones that aren’t getting UV. These aren’t guesses, our dispensory and grower customers report back to us with actual lab results, using actual control growing methods. Anyone who tells you they didn’t get more THC is probably using a reptile light or some similar underpowered UV source. Just as you can’t use regular screw in light bulbs to grow robust plants, you can’t expect high THC returns with weak UV sources. Ironically, the bad UV lights cost about the same as the good ones, it is just a matter of using the right lamps, the right way. And it is pretty easy IF you know how. With our standard 4 foot bulbs (Universal UV and the SG-1-40) you will use four bulbs for every 1000w (or equivalent) hood you have. Newer lamps such as those in the Flower Power series cut that in half, so you only need two lamps per hood. This means lower operating costs, even if the lamps are a little more expensive.

Proper usage

The key is giving the plants as much or more UV, in the right spectrum, than they would get if they were outdoors. In fact, you want to give them as much as they can take without being damaged. This means light on each and every bud, at least every other day. Typically, you would run the UV lights for your full light cycle, around 12 hours, as soon as you go into flowering mode or even earlier.

It takes more than just random UVB. We have found certain frequencies of UVB make the plant react more vigorously than others. We have reason to believe that UVA is also beneficial. While it doesn’t stimulate THC production, it penetrates much more deeply than UVB and may stimulated trichome production, which makes THC possible. This is why we have UVB lights with multiple “soft” peaks at the right frequencies, as well as strong UVA output in exactly the same part of the spectrum that the sun is strongest at. This gives you a sun-like glass tube that you control.

Conclusion

So does it work? Unquestionably it works as long as you use the right power level and right frequencies, and the pay off is often 100x the investment. This is huge. This is also why many growers are using our lamps, and why many growers don’t let anyone know that they are using our lamps: They don’t want anyone to know their secret, why they get the big bucks, why they have the best product. Of course, it still takes good light, good water and soil, good care and air, and proper technique, but UV light is just as important as those other things if you are after premium results.
