ok im new like you and i read and read and read the CFL Indoor GRowing forum, the thing i learned is lumens lumens lumens the more lumens the better you want enough lumens for at least 2200 per sq. ft. check out a few threads the have websites where you can order some for 23 bucks a bulb, but anywho check my grow thread "look what i stumbled upon" cause im using 6 cfls (1 42w (26L), 1x23w (16L), 2x27w (13L ea.), 2x26w (16L ea.) total of 10,000 lumens my space is 2ft x 2ft x 4ft, in three two to one bulbs sockets, 2 bulb to plug sockets, and one bulb extender with plugs on both sides set-up looks like an 2 pointed left, 2 pointed right and 2 pointed down all from the depot
also get you a light timer (wal-Mart 5 bucks or so) and a small fan (desk fan radio shack 4 bucks on sale) mylar for light to surround the plant or paint space flat white.
I hope that helps
