It's ground english walnut shell.
Thanks for the info but I'm happy with my substrate and have not had any issues with it to date.
Don't be afraid to listen to an experienced keeper like Jim (tricksterpup). I would never use ground walnut shell for substrate. Having no issues to date doesn't mean much. I drove with bald tires for months without incident, but replacing them was a good idea. I hope you never feed a snake on that stuff...
