What I have found out is that during the veg. i used the 42 watt cfls and the 23 watters. I used the larger cfls on top and used the smaller cfls for the lower branches. But for flower I used a large 200 watt cfl from lowes it cost me 17 bucks or so but i also bought more 42 watters so i could place the cfls in just the right spot.

But what I found out is that after a bought all of these bulbs, plug ins and a light fixture i could of bought a real cfl grow light on ebay for 100 bucks and i would of ben better off. dont get me wrong i bought what i could peace by peace and I had a single plant first grow and i grew 2 ounces of some goodnice.
