Start at 36"inches and work your way to 18" as the plant grows.

What would you say about my lighting based off the leaves of this auto? Too bright, too weak, or just fine?

Tent too hot?
I added two blurple lights - I'm not sure how much they're helping growth but they are definitely making the tent hotter - about 5 degrees F. I have a fan blowing at the bottom of the tent and at top over the lights but I'm worried that it might be too hot. Should I ditch them?
