You are correct about the GWS and the BM for vegging. I would use the 6500K spectrum CFL bulbs. The four was absolutly enough as far as heat goes. I had no ventilation besides opening the box every now and then but did have a little 8 inch fan in there with it. I also did change the lights out for the flowering stage I was using 6 CFL at the 2700K and 4 CFL's at the 6500K mark. They did just fine. But its weird cause every time I veg I try to exclusively use CFL's they give really, really tight internode placement which I think is key to nice tight monster buds. Thats another way to get my bushes besides topping them of course, over, and over. I am also only using 600 watt HPS for flowering because of the thick ass canopy's I am working with. I just dont see CFL's penetrating that well hell I have tried it and no light shines through all those leaves to the bottom.
