Ball Python Heating

[emilys_exotics]

Switching my ball pythons to 52 quart tubs and am having a hard time determining what wattage heatpad to get. It will be connected to a thermostat.
Any help would be appreciated. Thanks!

Its the size you want to worry about. Its usually recommended to have a uth that covers 1/3 of the cage floor. So whatever is 1/3 of that tub is what I would get.
