I'd put damp moss in ALL her hides.
The bedding looks like coconut husk. To raise the humidity I dampen the top of the husk and then mix it all around the enclosure. Repeat the process if it's still too dry. That should bump up the humidity quite a bit.
With the digital thermometer/hygrometer you'll know your actual humidity.
