There is a significant difference between allot and 4 or 5 low lumen CFL's. Start adding up the numbers of lumens/usable plant light, read up on some CFL grows and grow from there. Some people can pull a half LB from CFL's, but most don't. Some can pull off a LB from a 400W. You need to do the math and learn about the plants needs and life cycle.
Sorry I can't seem to help you much.
