I use Eco Earth Expandable substrate. It is made out of coconut fiber, it looks like dirt, and the peices are tiny. Luke burrows through it all the time. I have moss on top of it in some of the enclosure, and I grew some organic oat grass in some parts too. He burrows through it all the time, and there are rocks around the water dish to keep him from dragging substrate into the water. I spray it down right before I feed him worms because it tends to stick alot less than when it is dry... the pieces are tiny, so I don't think there is much risk for impaction.

Im going to try growing other things, like violas, to give him some stronger plants to play around in.

Thanks for the info on the burrowing substrate! I'm going to try it in my emeperor scorpion's enclosure
