Daylight are the best ones to use, because they have the broadest usable spectrum.
Some folks will say warm white are better for flowering, and in one way they are right. The plants prefer more red spectrum when flowering. But if you use ONLY CFL's, watt for watt, the daylight bulbs will give your plants more usable light.
All other factors being equal, more lux on the plant will give you better growth than more red spectrum from less lumens. Understand?
If you have two 25 watt bulbs, one warm and one daylight, the daylight bulb will give more light from the part of the spectrum the plant can use for growth, even though it would prefer more red in the spectrum.
