Hey everyone. I've had my ball python since mid summer and live in Wisconsin. The temperatures were fine at night up until now. At night the temperature has been dropping to as low as 64 degrees in the tank since we don't have our heat on at night. I have an under the tank heating pad, which the snake will curl up on top of on cold nights. But our winters can get really cold and harsh here. Do I need to get another source of heat?

I was thinking a ceramic heater on a timer that would turn on when my heatlamp turns off. But how do you place them in the enclosure if you have a top on it? And I want to keep the heat up at night in the most inexpensive way.

Any suggestions would be greatly appreciated! Thanks.
