try to get a small fan running while using the HPS, might help with the heat. and also get one of those squirt bottles and mist the plant a couple times a day.
slowmotion Reviewed by slowmotion on . Too Much Light? I'm growing 2 plants. Under fluoresecents they do fine, but when I put them under an HPS (high pressure sodium) light they seem to wilt and not grow well. The light is 2 feet above the plants. What is the problem? Rating: 5
