There are so many variables that would make or break your grow, what size room are we talking about here? lights? I am using 1.5gallon and would like to think that works for me. I have seen three and 5 gallon containers being used and I wish i had that kind of space. basically cannabis root goes deeper then wide so that is one thing to think about, another would be why donnie and marie osmond are always on ET show, and yeah i mean every frigging day, it could be a clip about dying meerkats and they will cut to donnie's thoughts.... eeeck
