Hey man, cfls (compact florescents) are really easy to grow with and they don`t put off a lot of heat so you can hang them right over the tops of the plants. You won`t have the plants stretching for the light. Go to Home Dumpo and buy some cheap shop lights that use 40 watt cool white bulbs. You`re plants will love it. Also make sure you have a timer connected to them, the fan etc.. I hope this helps, take care. Chili
