i dont have any eperience with that many plants but i would go for 6 under each lamp....its my gut feeling so you 'd be better off askin a more experienced grower. but i think like you, with more space and easier access for TLC i think they would do great..........
thanks mate, and thanks for being upfront about your 'guess'
i just transplanted all my rooted clones to veg, i'm veggin all 18 (well, 19 actually since a roomie wanted to try a romulan) and i'll be keeping one of the nicest looking for a mother, and maybe the rommy too. going to base this first one off the 18 as i had originally intended... and if it gets too crazy i'll pull some out. but i doubt it would come down to that... maybe more like me wading through a jungle. either way, if its bad - next time i'll do a bit less and let them get that extra TLC and spacing for light. if you're interested follow my grow - i know im excited!
Oh man im almost at the bottom of the harvest jar and i just want to say after nearly a four month cure the bud that is still there is smelling gorgeous and tasting ****ing great. next time i might to try to cure for 2 months at least before smoking......hahahaha oh man who am i kidding
