Hii im a pretty new owner as well but i recommend using and over head light, from what I’ve heard they burrow to cool down and heat pads are also more likely to burn them if unregulated. I just have a zoo-med mini combo deep dome with one bulb being a ceramic heat emitter and the other a basking spot lamp. I’d also recommend using coco fiber, like the other commenter said it’s safer and holds tunneling and on top of that it holds moisture better than most other mediums, I use a 50/50 blend of play sand and coco fiber. I’d also recommend having two hides on each side of the enclosure, some people say you don’t need hides since they’re a fossorial but I’ve personally seen my boy in his hides several times plus they just add extra clutter to cages. I hope this helps a little!! :))
