My rule of thumb for CFL's
Minimum - 100(real)W CFL for 1 plant, and at least an additional 50(real)W for every extra plant.
I use a 3:1 ratio of lights for a fuller spectrum. Veg 3x6500K, and 1x3000K. Flower is the other way around (but I recommend HID).
Place the CFL's 2 - 3in above the canopy for best light penetration.
I use cheap assed vanity mirror light fixtures (cheaper/better than y-splitters, imo), and the reflector is a flattened piece of 8in vent pipe.
Good luck
