compacted flourescent difinitely save u more power, and they are very sufficient for growing, but only when there are a bundle together. If you want better stonier plants, get a hps, hps develops the crystals better becuase of its red spectrum, and a mh is better for growth, cause of its white spectrum. if you want to combine the two, get an EYE HORTILUX for and hps ballast. for your small grow, u should look into bubbler buckets, they work great, and you can get all the supplies at a hardware store for cheap!
