The ONLY REAL UVB artificial light source is flourecnt. You can get it from a 150 cmh from Endomaxx but it's supposed to be double jacketed and it's not. Plus I wouldn't buy a glass of water if I was stranded in the desert from that idiot.
Look at these guys www.solacure.com

so you averaged all the shit growers on youtube sounds to me..... What about growers like Growmua5 who regularly pulls 1.5 to 1.89 gpw DRY in case you thought you'd try that old saw again. You keep those 20% efficient T5s and 25-35% efficient HPS etc lights. This is the same old bs every LED troll tries to peddle. Your more than welcome to believe whatever you like, i know what I produce, and the quality.
And growshops are all controlled by middlemen who supply them their stock, and they are TOLD what lights they can sell, so of course they will pitch HPS. Funny though, Gavita dumped its HPS operation to go LED...........
And explain to me how Samsung chips got on a brdgelux strip???..............
Personally, I'd get my advice from the old lady growing flowers next door before I'd listen to 90% of growshop owners.

not exactly true. I have seen 2 honest LED growers here. of course they were criticized by the rest of the LED crowd. that being said I have used the bridgelux ED strips which use the same samsung 561 diodes and they are much more efficient than the older bridgelux diode and even most cobs. they do provide more uniform light distribution but will burn plants if placed closer than 15 inches away. plant do require more care to deal with the deficiencies that occur with LEDs and yield and quality was lower than test grows with a 150 watt hps.I'm a T5 PU MMJ closet growers but I like experimenting with other types of lights and from grows on you tube and test grows by green house supply companies my disappointing experience with LED is not uncommon. no hydro shop of garden center in my area carries LEDs and none recommend them. T5s are by far the most popular grow light with HPS holding a strong second place although cmh is a strong and upcoming challenger.the LED crowd is a very vocal minority. why do you let them upset you? or do you just enjoy arguing with them?on you tube the average yield is about 0.3 gpw for cheap multiband leds and 0.45 gpw for high end lights using cree or osram LEDs so when a small group of stoners claim that they can beat conventional grow light by an incredible margin using homemade grow lights most people who have done their homework just ignore them. I could claim 2 gpw if I weighed my buds after trimming but before drying

UVB contrary to popular belief, has NOT been proven to enhance THC. there are only a handful of studies, and they all contradict each other. When I see PROVEN scientific evidence, substantiated by peer review, Then I'll invest. In the meantime, everyone messing with UV needs to remember how dangerous it is. Is it really worth messing with even if it really gives 2% more THC?

Thanks. I have seen debates about whether UVA or UVB sources are more effective at triggering a defense response. What do the CMH bulbs give off?
@pop22 - the efficiency rate of LEDs over filament bulbs is ridiculous! People are slowly getting it. I guess if people have unlimited free electricity then they won't mind running fans and air conditioning to cool all of their HPS lights.

Most LED does not emit UV light. This is a feature, not a bug. I've grown some of the best quality product I've ever enjoyed under LED lighting, so the use of UV supplementation is strictly optional.
My advice is to use a T5 UV spectrum lamp. There are many available in 2' and 4' lengths. They're quite affordable. I suggest running them on a separate circuit than your main lighting, so you can shut them off while working in your garden. UV light is bad for people so I don't recommend working under them while they're lit.
UV LED does exist, but it's extremely expensive and doesn't last very long. T5 UV lights also need to be replaced every few months, see manufacturer's recommendations on specific lamps, but the price makes it an affordable expense.

It's important to harden plants off to UV lighting as its intensity is higher than anything in the visible spectrum. They can handle it but need a gradual ramp up- or add it in veg so they're ready when you flip.

I really don't think that any HID lights give off enough UV to make any difference, with two exceptions;
One, Mercury vapor type. These are not efficient and so they aren't a better solution than T5. T5 UV lamps are also available in a wide variety of UV outputs so they're effectively more tunable.
Two, broken lamps; if the jacket is missing, they'll produce a lot of UV. That is a far from prudent option, since that risks mercury exposure if the pit fails and scatters its contents throughout your grow space. It will also burn the shit out of you working under it and still needs to cold start. Bad idea.
T5 is just a better solution for UV supplementation all around.

"Lab tests prove that Solacure bulbs can increase THC production by 30% or more."
I have a hard time believing that statement......

And loads of space for the ballasts.....
I am using Arcadia T5 HO 12% UV bulbs. 6-8 hrs/day....

Im using some cheap plurple full spectrum chinese cobs which have both uv a and b as an experiment to control stretch/ and initate flower let you know my results. So far i started them week 2 of flower and it stopped stretch so well see if yeild is affected and anything else.

Blurple and full spectrum are all but mutually exclusive terms. Blurple excludes most of the spectrum, more or less by definition.

And yes they probably have no uv a/b in them just a test

And i personally have changed a 100000 bulbs and ballests in every fucking kind of hid light ever made. Screw hps and metal halide. Solid state lighting is just a much simpler longer lasting idea of producing light. I look at a qb and im like boy probably 10+years of same quality light sold forever.

They were sold as full spectrum look more pink then anything
