Lighting issue

[arliss]

I have a stealth box, in the flowering chamber I have 2 T5 lights, 1 on each side and 1 Led center Kind LED L300. When using just the T5 lights the plant seems ok growing slowly. When I turn on the LED for any length the plant appears to start wilting. I have moved the LED to the highest position possible. Is this a heat issue I am wondering or is it too soon to use the LED? The plant started in soil and when it was about 8" high I transplanted it to the box following the instructions. I started with just 1 to get the hang of it.

AT 8" high it should be ready for some decent light. But if it is wilting you need to listen to the plant. It does sound like a heat issue. Back the LED off a bit. How far is it from the top of the plant? What sort of ventilation do you have in there? What are the max temps at the top if the plant?
