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 29? x 15? 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 14? x 15? for each plant. That, or a SCROG or SOG grow.

Have you thought about using CFLs and T5 lights? You can get single bulb 24? T5s pretty cheap, and daisy chain 3-4 of them. That will add a lot to a CFL grow.
Roughrider Reviewed by Roughrider on . 2x200w cfl or 1x150w hps for flowering i am gonna be growing in a cabinet that is 29xlong,15,xdeep,60xhigh and need light edvice.I am not a begginer,i have alot of knowledge on growing and know alot its just im decideing on wether to go cfl or hps.The 150w hps puts out 16,000 and from what i heard thats good to grow about 3 plants but im really wanting to grow 4 with the best results.But if i was to get 2x200w cfl that put out 10,000 each in a vertical hanging position wouldnt i be doing better sense its more lumens and less Rating: 5
