High Tiffany, glad to have ya with us. The more time you spen here the more you learn about your BP, anf how they are so different from each other.
When I first started with my BP, i used newspaper. But now I use Cypres Mulch for his substrate. It looks good, and it holds humidity in better than some of the other substrates.
Humid hides are a good idea if you can't keep their humidity in check. I do not use a humid hde, and have no problems with his shed. I try to keep his humidity at around 60 - 70% during the shed cycle.
Glad to have ya with us.
