Mr. Blue Seed: you might want to look at SeeMoreBuds CFL lighting set up in his book, "MARIJUANA BUDS FOR LESS." A couple of my friends that copied his design are very happy with it. If you have the room, you might also want to consider the use of 'aimed Mylar covered reflectors' to get the light down to the lower portions of your plants. That's what I did with my Aerogardens and it worked for me. HSA
