My hood is vented with a glass barrier on a light mover so it does not stay still above the plants for more than a few seconds. My therory is that this is why I can keep them as close as I do. I check them everyday during the lights on to make sure we have no burns and so far so good.

Thanks for the input.
Your lighting theory sounds valid to me. My lights aren't enclosed or vented.

Rusty always nails it. :thumbsup:
