I got my first ball python a couple weeks ago, and I have been having trouble keeping my temperature consistent. I don't want to do anything to hurt my new girl, so if anyone has any advice that would be fantastic. I have her in a 10g glass tank, with a uth plugged into a thermostat on the hot side and a heat lamp on the cool side. The reason I have a heat lamp on the cool side is that my room can get chilly, especially at night, and the temperature on that side is way too cold without it. I use cypress bark as a substrate. Even the hot side, which is plugged into a thermostat, fluctuates! I have two probe thermometers, one for each side, that I believe to be reliable.
