I've been using aspen shavings as a substrate for my newly acquired adult red tail boa, have had her almost two months now. She likes to go into her water bowl a lot and then the substrate ends up getting kind of soaked. That in conjunction with the humidity seems to keep the substrate pretty moist in certain areas of the enclosure. I have not noticed any mold in the substrate at all, but is it ok for the substrate to be consistently moist like this?
