I am planning my grow room, and I am planning on having a 400W MH for my veg room and 2x600W HPS for my flower room (does this sound good? will a 400w MH be enough to keep mothers, clones and veggin plants happy?)
I searched the forums and found two great threads that contained a ton of info on lights and electricity. One of the threads said that a 600W light would cover a 5'x5' area, while the other thread said the same light would only cover a 3'x3' area.
My question is, which one is right? Should I just plan for a 4'x4' area?
Dunno if it helps, but I will be getting digital ballasts and each 600W will put out 95,000 lumens.
