I was definitely wondering about mounting UVBs in each corner

just got myself a few 100 watt uv bulbs for reptile still to hot to use them but when it gets a bit cooler goint to put them on a timer to come on 10 minutes before lights out see if that boosts tric production :smoking:

I run the UVB on my California Lightworks throughout most of bloom. I'm not sure 15 minutes once a day would be the best way but that may just be due to the fact that sunlight is constantly emitting uvb rather then intermittent. I would be interested to hear how the 15 minutes faired for you =)

the reason for that time is ive read to much uv hurts the plants could stunt growth ive just started 2 Heisenberg specials I'm gonna try the uv lights on them I just hope the temps are down during flowering
