Ok I'll add a few more inches of substrate. And also the T is actually a little bit under 3 inchesI'd say no. This is a burrowing species, and needs the room to do so. How large is it? It looks to be about the same size as mine - 4" dls. My girl has 8" of substrate, and she's still dug to the very bottom. I'd offer her more if I could. Also remember that this species likes it a bit humid.

Alright, fair enough. Although I'd personally put it into a new home entirely, there's not much room in there. I'd expect that spider to easily dig down 5", most likely more. If you want a KK, then I'd just go with one of those large ones at the pet store. That will give more than enough burrowing room as well as room to grow, since your current setup will require a rehouse on the next molt.Ok I'll add a few more inches of substrate.
