Trouble on the cool side

[George1994]

Okay. I was under the impression that I needed a temperature gradient, which is what I was aiming to provide. So would you suggest that I skip the ventilation holes and lower the thermostat to try and get the whole enclosure in the lower 80° range instead of having a warm/cool side?

You should have a temp gradient. Allowing the snake to thermoregulate is natural. Vent holes will lower your ambient temps. That is what I was assuming you meant to be honest.
