600w = x auto's?

I am about to buy 5 auto La diva and 5 auto Diavolo (both fem) and i have 1 600w hps light in a nice size closet with mylar everywhere...wondering how many plants i could grow under that if im doing a 20/4 cycle..maybe 20/0 not sure yet, would like to do all 10 seeds if possible, trying to yeild as much as possible!!

noone at all?!

how much space do you have? you will need at LEAST 4x5x6 to grow 10 plants (it takes me 5x5x7 to grow 10). lighting shouldn't be an issue with 10 plants under 1 600 watt as long as your rotating them every 2-3 days..... space will bi your biggest issue i think, just make sure you have the room to fit their grow bags/pots in there
