U need a thermostat on the uth!! Three inches of aspen is way to much. I’m sure an expert will chime in but those fluctuations in temp and humidity is not good. I also don’t condone feeding ball pythons in a feeding tub. 100% unnecessary. Most people do it so they don’t get bit as a feeding response. But I’ve never been but by a ball python of my own. U learn to read them really quick
