Ah, I should have clarified which probes. My bad. The probe in the tank is the thermometer probe. My set-up basically goes from the bottom: heat mat > thermostat probe > glass > thermometer probe> then substrate and hide. I've got that all worked out. Just trying to get things situated temp, humidity, and substrate-wise before getting the snake. I've had a change of plans though, and decided to order the snake online instead, so I'll have a little bit more time to set-up. I don't want to wait too long though, as the place I want to buy from won't ship if it gets too cold, and I live in Ohio, so I'll probably try for this week.
