I mix eco earth with reptibark and have a good hold on humidity issues because my house is at 15% humidity.
Gotta love upstate weather.
My Bee once swallowed a piece of repti bark but he passed it fine, scared the crap out of me though.
So, now i keep the bark away from the hides so it will help prevent any of that in the future.
I also put aspen in the hide to hold in heat and cushness.
