    6500k spectrum bulbs are ideal amongst CFLs for vegetative growth as they emulate daylight (plenty of blue spectrum).

    The main difference between those bulbs are the lumen output of each respective unit. You should figure out the lumen output you need based on the space you are using and the number of plants.

    So we know you are growing 3 plants, what are the dimensions of your grow space? Also, is it a cab grow? closet grow? More info the better.
     
  3. i am goingt be useing a grow box 2x3x4 feet...
     
  4. For only 3 plants in that small of a grow space, you may be overdoing it even with the 125w bulbs. If energy conservation is an issue with your project, you may want to dial down the wattage a little. 3-6 68w 6500k CFLs would do the trick for you in that case; maybe even less wattage.

    I have heard the metric of 100w/plant used before. But I think that highly depends on the quality of the bulb and the spectrum of light it emits. CFLs radiate so little heat though, you can bring whatever light structure you design right down on top of the plants practically.
