Building a Grow Cabinet using a Sterllite Shelf Cabinet. Need Help!

I have a sterllite cab that I'm about to assemble, and use as a grow cab, the dimensions are 2' x 1'.7 "x 3'. I have a Sunleaves lightwave CF meant for cfls http://www.sunleaves.com/detail.asp?sku=SLC190 that can use up to a 250 watt cfl, which I plan on using with a feliz 250 watt, and this fixture takes up most of the space, so I can really utilize it in this small space. Anyways the question is with that kind of cfl, and the space its in, how many plants could I grow in this space? I was gonna do 3 maybe with lst, also the pots are 2.5 gallon, and 12" tall. Also the dimensions for the light wave are 1' and 7.75" x 1 ' and 1.75 " x 6.5". Need help as I am needing to start this grow immediately. Thanks!

why not go with a 150 or 250 watt hps? that is a very small space ever thought of trying a scrog set up? 1 plant properly trained can produce just as much as 3 smaller plants. would also suggest looking in to airpots (air pruning for roots) depending on the veg. time 1 pot can be used from start to harvest.

Well lst would be better for me, I know that technique pretty well, and I haven't done a scrog yet. I plan on using solo cups, and then to its final pot. I've also considered an hps but I was a little intimidated on the heat issues, but I do have an computer exhaust fan, that pushs out 110 cfm, and my intake is at 72 cfm. It's really not as small in person ,just on paper or writing... its pretty decent size for a nice little grow. If needed I can just do two pots instead of 3. But I'd like to hear some peoples opinions about if I could do at least three.

Got any pics?
