yeah hes such a science teacher!

That vid has extremely good information on trichcomes and their function.

uv light is supposed to help that but it is also dangerous to humans. thats why big lights dont have that or they have protectors/shields or something. some is needed but the only thing i can think of that use those lights are reptiles and coral.

Why reinvent the wheel?
Mercury vapor lights aren't practical indoors.
As it stands, your average home grower has 3 options: Flouro (with the selection to choose from, you should find SOMETHING you like!), MH, and HPS. Each has its place in a grow room.
Forget about trying to boost resin with crazygonuts lights and UV. Try molasses instead... low tech, high satisfaction, no skin cancer. I promise.

I just saw the scientific correlation of UVB and actual THC production in the gland itself. That was they crux of my query.

As for just googoo resin glands yeah the blackstrap is great.
Just wondered if people used these supplemental lights and if there was a actual increase. Of course we would need all kinds of equipment to actually test this. But I'm sure someone already has. Not to mention there is probably some kind of ceiling to how much could be produced anyway.
Hey I just search find something cool then bring it back.

The outer globe for a MH bulb is made to stop UV from exiting the bulb. BUT if the outer globe is broken you will cook the hell out of you plants. And if stupid enough to be in the same room when when one lights of. YOU will get to see the doctor after a few weeks, cause he will take the blind folds off you eyes.
Friend got to close to a uv lamp and " its like having sand in you eyes and you wife gets to drive you around.
merk lights are way off in the total specturm, cheap but worthless.

uvb seems to be a very hot topic for indoor growing these days...and i;ll admit, i jumped on the bandwagon!:stoned:

ive just added 1 reptisun 24w 10.0 uvb reptile bulb to my existing setup of 1 600w HPS + 2x 24" T5 blue lights, in a 5gal DWC bucket for my single, spoiled sweettooth mother.

this light is approved for use with pets, but i still turn it off when entering the grow space. after researching uvb abit, and watching that uvb and me video on youtube, im a believer that this technique is legit, when used correctly... but i will have to wait till harvest to show off how frosty my baby will be!:jointsmile:

Cool I would like to know your findings. Seems like it would only be a supplemental light anyway.
Good luck.

This guy has a pretty qualified-sounding explanation on the role of UVB in THC conversion

There's no UVB coming out of the other lights because most glass absorbs UVB.

You could just tend to your crop with sunglasses on. Plus you'll look cooler.
