I'm picking up my ball in about a week so I thought it'd be good to start setting up the tank to make sure the heat/humidity levels are right when we bring her home. I couldn't get the belly temperature up high enough with aspen bedding, so I decided to try repti-carpet. The repti-carpet was warm enough, but I wanted to know if it's alright to keep it with just the repti-carpet or if I should invest in another heat source and add aspen on top of it?
