I use care fresh small animal paper bedding. It spots clean very well and absorbs moisture from urine good so I just have to pick up the spot and a little around it and either add what I took out or spread bedding from other parts back in. My humidity is perfect is all my setups. I don't use white bc I heard it has bleach in it but idk how true that is. Some people say it molds but I have never experienced that even with my one set up that has a misting system. I haven't used it with a rack but the breeder I got my super pastel uses it in some of his racks and recommended it to me so that's why I use it.
