Hey Benny
I'm not in a 4x4 but i run 1200w in a very tight space. less than 3 feet of width. 2.8 x 6". I have branches less than 6 inches away from the bulbs at times... but I make it work. Using a vertical light mover, scrog'n to the walls, and not growing in the summer all help me to get thru it. I bet you can do it in a 4x4, but it will definitely take some work. My space works out to approx 70wpsf, and the buds are much much better than what I was getting with 800w.
I probably fried less than a dozen fan leaves this grow, lol
