2x200w cfl or 1x150w hps for flowering

[Roughrider]

Two big CFLs are going to generate plenty of heat. And a 200w CFL that puts out 10000 lumens is way inefficient...almost 30 percent less efficient than a 23w CFL that puts out 1600 lumens.

And I can tell you now...you're not going to get four decent sized plants in a 29â?� x 15â?� floor space. That's 3 square feet...enough for 3 pretty small plants. If I were you, I 'd definitely go for two plants in that type of space...you've got about 14â?� x 15â?� for each plant. That, or a SCROG or SOG grow.

Have you thought about using CFLs and T5 lights? You can get single bulb 24â?� T5s pretty cheap, and daisy chain 3-4 of them. That will add a lot to a CFL grow.
