Hey everyone. Im trying to find out how many bulbs would produce a great yeild using cfl's. Im starting with five clones of big budx widow and i want to get the most out of it. The problem is im limited space. My cab dimensions are basically 2.5'w x 3.5' l x 4' 7"h. I want to go with cfl's and maybe one 150 - 200 w hps. Any suggestions on how many bulbs would be needed and the draw?

[h=3]In a nutshell…[/h]Lumens per square foot:
Minimum amount of lighting needed is around 2000 lumens per square foot.
(Two – 23 watt CFL’s, per square foot*)

Mid range is around 5000 lumens per square foot.
(Three - 23 watt CFL’s, per square foot*)

Optimal is 7000-7500, or higher, lumens per square foot.
(Five – 23 watt CFL’s, per square foot*)
