Ok I've read enough to know that most growers prefer HPS over cfl's for flowering. But with that said I still have a question.
I plan on doing a small grow (2-4 plants) in a 6 sq ft grow box. I will have a total of 16 cfl's for the grow and will have a minimum of 25,600 lumen for vegging and flowering (I may throw in some higher wattage bulbs if I have the money) . I plan on using daylight bulbs during vegging and replacing them with the appropriate kelvin rating for flowering.
With that said do the experts out there still think I would be better off going with HPS bulbs or will I have plenty of light using cfl's for such a small grow?
Thanks in advance for your help.

you may get nice big buds with cfl but an hps will make the buds more dense/heavier/bigger. you will always get better results the brighter the light..

they will work...but an hps will work alot better and much more efficiently...

Thanks for the reply. I found a Sun System HPS 150 Grow light fixture with a bulb for $70. It says it puts out 16,000 lumen. Using the CFL's I would have over 25,000 lumen. Would you still go with HPS? Thanks.
