i agree with superman. 1 big one and some smaller ones. im using a 43w and 4 26w and they are doin fine. And ya im doin cfl all the way but when i get a bigger place and some more money ill be getting a 400w hps (about 200 $) for flowering. But just for veging cfl's are all you need.
It won't work for them up to that size, you will need some more. I have 2 105's and they were not enough once the plants get a bit bigger.
