is that an aerogarden? your going to want 200watt at the very least.but i would reccomend 300-400watts , so wats that 6-8 50watt cfls.or just go buy a 250 hps or u can buy 100watt cfls with a reflector on it from your local hydro store
Its similar to the aerogarden, minus the light fixture and the stupid timer system.
I have a 400w grow light that was used previously, But its to strong and large for the tent. If i was to go with the 200-300w light would i need any others?
