I'm going to try building a manual light mover in my flower room. I've got a 1000w hps air cooled. I'm going to use the upper rail from a hanging closet door,attach my light to a couple of the rollers and every evening move the light from one side to other for 24 hours. In a way it would be better than a motorized system because with motorized the center still gets most of the light. This way I can alternate the foot print
