Lights...yes, I got me the right kind of grow lights, neon, and are specifically designed for plants...so no worry there...have always had a pretty decent green thumb...use miracle grow about once a week...got a fan blowing...use the light about 12 hours a day...sometimes 11 sometimes 13...but the plants are healthy, no yellow leaves...solid stalks...and the temps are about 75 degrees on the average...
