Im not exactly sure on how much you want to run... how many plants will you have? You can also get away with running less while theyre seedlings. I am currently doing 2 plants in a box. Both are seedlings at the moment (1 baby broke ground yesterday and 1 a few days before that). I am using 4 23W 5500k CFL's from home depot. Once they get a little bigger, I will be adding 4 40W 6500k CFL's as well. Once they get too big for the box (I set it up with the intention of growing only 1 plant), I will be moving one out and maybe building a new rig for it or something. But I will keep those 8 CFl's in that box for a single plant and I think that should be enough.
If other people's advice is different, they are likely right, as I am also a first time grower, but I believe my setup is fine. So hopefully that gives you something to go off of.
