ah good CFL's to grow with then...the higher the actual the farther it penetrates...3 of those should be PLENTY for 1 plant...you could probably do two as well no probs...just keep em within a couple inches and use the oscillating fan to increase stem strength and move the heat
Now those bulbs are best for the flowering stage as its around 2700k, yes you can use them for the veg stage, but they are not as effective. I would pickup two "Daylight" bulbs that should be in the 6500K range that you need for the veg cycle...use those two + one of your soft white's for veg, then swap out one of the daylights for a soft white for flowering. Its good to have a mixture of spectrum as the plant needs it all during all periods, it just uses more of the specific ranges during those specific stages.
