It's being heated by a RHP connected to a thermostat. The thermostat is set to 90 and the side below the RHP holds out between 88 and 90 day and night, but the cool side/ambient temp is staying at 86. So I need to go ahead with the ventilation holes, correct? I'm sorry if I'm confusing! I know I've confused the hell out of myself.
Edit: The snake won't be here until this week, so I have a few days to get everything sorted out. I don't want anyone thinking I'm cooking a snake while trying to get everything adjusted.
