UV Results from the community.

Check out the cutter strips. They have 2 channel UVB/C boards with two peaks, one at 310nm and one at 280. I will keep using my arcadias for a while as they really seem to bring the terpenes out and I already own them, but eventually plan on adding them to my grow.

I read a book by Mel Thomas where he talks about using facial tanner/ tanning equipment in his grows to effect the thc production of the plants
I see there are different UV bulbs for tanning, some are mostly uv-a some are mostly uv-b
He says during the peak hours of the day, the lights are turned on for 3 seperate 15 minute intervals. I forget what he said the THC increase was, but I mean three 15 minute intervals a day might not cost alot of electricity to get a more potent bud in the end. Interesting thread guys!

HTG is AgroMax. The PureUV bulb is 75% uvb and 25% uva.

i have been using that one since 2015 i think. they made a 100% uvb bulb at one point in time but stopped selling it due to complaints. i have to ask the old manager of my local store if he still has one or the packaging somewhere.

Well,... I used 285nm seoul viosys led 3 hours and a half maximun with 60 mw output.. But also I used all time when lights on 365,385 and 410nm leds about 30 watts per square meter at flowering time. I used UVB since Veg , but increasing slowly exposure to the maximun at flowering time.
