Kelvins my man. For vegging you want really high kelvins like in the 6000's range. For flowering you want the light to imitate the late summer sun so get the CFL's with low Kelvins like in the 2000's....and always the more wattage the better...youll probably want around 250 watts for vegging and 400-600 for flowering.

6500k mostly with a couple 4500k for veg, for flower I would go heavy on the 2700k with a couple 4500k and a couple 6500k just to round out the spectrum. For a good flower you need around 20k lumens.
