I was an active member here about 5 years ago. I was running a DIY UC system using 25 gal commercial trash bins, with tons of vertical lighting (checkerboard layout), in a warehouse. That to say, I'm not a newbie, but I am considering something new; only because everyone says using higher quantities, running them quickly through a scrog setup of some sort. Ok, I get it, I know how, but.. I like growing big trees damnit.. Should there be a huge difference; if everything goes accordingly? Or are we talking 10%? Your thoughts please.. I just built an 8x16, slammed full of soundproofing rockwool insulation (R15) - double layer 1/2 sheetrock wrapped in panda. I have a brand new 2 ton mini-split, 8 Phantom 2 digis, and a TON of carbon filters.. I bought air cooled hoods for setting up the scrog, but, as time draws near, I have to make a decision. I have the environment for bare bulbs, the heat is no problem. What is your opinion on the subject?
