How would you go about lighting a system with the intention of growing fruiting plants as well as our tried and true leafy greens indoors?
For greens, 2x4 lamps with T5 high output fluorescent will work. You have to put lamps with an adjustable cord so you can adjust height as the plants grow. Keep the lamps 12" to 18" height from plants. Also, consider purchasing Black Diamond Perfect Sun LED lights, very expensive up front but longevity and electricity cost are minimum. These actually duplicate the sun's color spectrum.
