Uv for thc

Is it true that UV bulbs will max THC and Tric production

I read different threads but havent gotten any straight answer..

I think its just one of those up in the air things. Most ppl just give their plant 2 straight days of darkness for more trics

Cannabis plants use trichomes filled with THC as protection from UV-B ratings. I've changed over to using CMH bulbs and one of the reasons why was the increased UV-B.

You can buy specific UV-B bulbs but you need to be EXTREMELY careful. Make sure the bulb is on its own switch and never, ever, work under it.

Although I don't believe in the two hours of darkness rule that is based around the idea that a dying plant will attempt to produce as much fruit or flower as possible so it has the greatest chance of spreading offspring. I think the 2 days of darkness is more of an old wive's tale than anything.

If the UV bulb is on durin the 12 dark hours , will the plant see it ?

of course. plants absorb most colors but the green spectrum. to humans we might not notice but plants do see it

Metal halide bulbs produce an abundance of light in the blue spectrum. This color of light promotes cannabis plant growth and is excellent for green leafy growth and keeping cannabis plants compact. It is the best type of light to be used as a primary light source

High pressure sodium bulbs emit an orange-red glow. This band of light triggers hormones in cannabis plants to increase flowering/budding in cannabis plants.They are the best lights available for secondary or supplemental lighting

Hope this helps

Mixing spectrum of lights always makes my stuff go crystally as hell. Even adding to the HPS with some BIG CFLs in a slightly different spectrum seems to help a lot.

I haven't been doing that lately but I think I am going to try it again.
