OK, well, heres how my set up is going to be. I have 3 400w ballasts. I am going to set two of them up next to eachother, to veg. my mothers and vegging clones. It's going to be aeroponics. I'm going to have at least 5, probably closer to 10 mothers. Around 40 (at least) clones vegging at a time. Want to do more, closer to 70 (a month). But how many plants could I flower under one 400 watt light? Will I have too many plants for my own good? Should I get another light for my flowering set up or could I flower over 40 plants a time under 1 400w light (in an aeroponic set up)?
