you should be able to still have good aiflow between plants....if the leaves cant blow around then to me its to packed and can create some probs.
i have a small grow (4sq ft) with a 600w...so i try not to pack it too much..6 2gals fit well but i can also fit 2 1galpots in there to, but it starts ot get crowded
cool, cool, that helps alot! idk what happened but somehow i had a bunch pop up right in the middle, about 4 in a inch space, should i let them grow n see wich ones take off?
