How many watts?

[ddkm82]

Hello all. I am working on putting together my new grow box and am working out some of the last details. I have a mother room that I plan on keeping two mothers going. The room is to be about 20 in wide x 30 in deep x 48 in tall. I was planning on using cfl's to keep them going. What size bulbs should I be looking for? How many should I use? Plus I will have a smaller room for clones. About 24 in wide x 30 in deep x 12 tall. Same question there. How many and what wattage? Thanks for the help.
