Hey Apostle,

I think 600w is too much for cuttings cuz they got no roots yet and they can't transpire. Try using Compact Fluorescents (CFLs) or even tube fluoros. For one thing, the light is like mellower and the plants don't have to work so hard. Plus fluoros are way cooler so you can keep them down close to the plants. I'm using strictly tube fluoros atm and I try to keep them 1 to 2 inches from the tops.[attachment=o76981][attachment=o76982]You just have to keep raising the lights, but the plants don't have to stretch up to the light. Just my opinion
