I had massive heat issues that killed 4 seedlings and damn near took two more....Never overlook heat, and heed the advice. I ran at max 30degrees lights on.

Anywhere from 82 to 92 where I'm at works fine. It never stays near the upper end of that spectrum for very long. Try to keep it between 82 and 85 at the canopy. My RH is 25% or less most of the time.
