Substrate for digging?

[SketchyMom]

I've been trying to figure out the best substrate for Sketchy to be able to dig. I thought I found it with walnut shells but just before buying a bag I read that thats a big no-no. I'm feeling like anything I put in her enclosure comes with a risk of impaction when I feed her Dubias or crickets. Looking for any suggestions on a diggable substrate just for a section of her cage around and under her hut. I'm keeping tile throughout the rest of the enclosure.

I’ve heard not to use sand because they eat it and it stays in their belly, eventually their belly will start feeling like a sandbag, I’ve also heard that it cans bind them up so they can’t poop. Just what I’ve heard from looking at a lot of different sites.

I looked into calcisand. It seems like everything you look at has a horror story attached to it. Its time for a check up anyway- we'll see what the vet thinks too.
What about egg laying boxes? I'll look into what people use in those.
