this will be my 4th harvest. i've grown two in a rubbermaid box with 8 23w, and the one i'm cutting today is looking SICK. i'm amazed at the fat dense buds i was able to get off of a few cfl lights.
I think I will end up going with 16 x 23w, rather than 8 x 42w. The reason being that this will mean that a much larger amount of the screen will be directly under a bulb, as opposed to the larger gaps between the 42w.
then again, maybe i'll try a harvest with the 42w that i already have, and see how that goes. after all, it's not like it will be my last harvest

plenty of time to experiment....
