go to home depo, or other hardware store, and look at the lighting center. you should see floresent(sp) tubes of all wattages and size. also they may have some outdoor lights that are high pressure sodium (HPS) bulbs and ballest in one. i would buy around 100w of tubes for one plant in the veg. state, and then buy around 200w hps for the flowering. that will be a good setup to start with.
