you could totally penetrate the center using cfl's on splitters and in fact, I think you'd grow massive amounts of bud that way. Can't wait to see the pics man.
You may want to think about more of the bulbs you have - SeeMoreBuds recommends in his book roughly 2 -3 of the 42 watt CFL's (compact florescent light) for each plant. Keep them pretty close- about 3 inches - to you leaves.
