If you want to seriously grow a few plants, buy a 400W HPS. The light is the most important thing, soil or hydro. Then comes nutrients. You can have the best nutrients, but if you don't have a big enough light, your plant will produce wispy, under-potent nugs.
he may not need an hps, but it is a lot easier than having 9 cfl's. but we both agree that he obviously needs more than that 1 cfl to grow a plant.
you can get 4 x 23 watt cfl's at walmart for 7 bucks.
6400 lumens for 7 bucks. add that to what you got now and you can flower. you won't yield a whole lot but enough to smoke.
