Hello , hope you can help on this matter. My plant is 7 inches tall and I just transplanted it 2 days ago and changed to HPS light. My question is do I leave the light on constantly 24 hours a day or should I go lights for 18 hours on and 6 hours turned off? Or maybe 20 hrs. on and 4 hrs. off? Any help you can give me will be appreciated. thanks, Farmer Bob
