Hi Tranoble, nice-looking grow(s). How do you seal your room? Do you mean just applying silicone caulk wherever two walls/edges meet?
Also do you use CO2, and why do you use Growth Excel at lights-on (usually people foliar when the lights are about to go off, so the plants stay wet longer and won't burn from the lights). Did you say you apply it twice a day?

thanx

You can post reply's with any specific questions and I will answer them best I can. My pictures of my room are 1 week from cutting down. Based On A 4 Light Room. Pictures are of a 8 Light Room. I start by sealing my room as best I can. From there I start by building a 8ft by 8ft box with 2x6. Then I screw 2 sheets of OSB 4x8 sheets to the bottom (sort of like a water bed box). I line the inside with polly making Rating: 5
