yep i've been reading this thread for day's now but for a newbie I think i'm doing very well with my show so far, i'd like to post you some pics but I don't have a digi cam right now. I'd say after the first round or so i'll try to invest in a co2 system but u know how it is when u first start out, how tall would u recommend I veg them before flipping 12/12?
