First off, I'm not a complete newbie to snakes.... just BP's I have my BP in a Sterilite tub, with a UTH and themostat hooked up. My infrared gun reads 90-94 on the hot basking spot, and low to mid 80's ambient for the hot side. The cold side is usually a few below that. My problem is, I can't get the ambients to go up any higher, and my old house gets cool at night so temps sometimes drop into the high 60's ambient in my room. The UTH and Thermo work just fine. I've messed with the quantity of air holes, and all it did was change my humidity.

What can I do to increase the ambient temps in there? Or are these numbers okay? I feel like they aren't. I don't want to raise my thermo too much higher, cause it'll get too hot for the snake to sit on.

I've only ever dealt with Corns so I'm new to this whole BP heating thing.
