@hightech316, thank you so much and admit-tingly I set it as high as possible. I always let my lights run as high as possible and let the plants grow into them. I don’t mind doing this due to the size of the grow my electricity doesn’t suffer too much. If you are concerned about maxing input into output for profit cocoforcannabis has par ratings for this light at different heights. You can use his review to get your height almost perfect.
