I've always been told, that you want the lights as close as you can get them, w/o increasing temps at the canopy. A good lazer type temp tester is cool for canopy temps, but I was told a good rule of thumb is, if you put your hand over the canopy and it doesn't burn you, it won't burn your plants. Light intensity decreases DRAMATICALLY the farther from the plant it is, so as close as you can w/o causing stress!

:yeahthat: Lower your lights as close as possible, as long as you can hold your hand right above the plant comfortably it's not going to burn your plants.
