We just recently added a baby Red Footed Tortoise to our family. The enclosure we made for it, is made out of a 30 gallon Rubbermaid tub, with about 2 inches of substrate made of Eco Earth compressed coconut fiber, and Repti Bark fir bark. We've been told it's best for a baby to have about 80 % of humidity in the enclosure, but our gauge in our enclosure is reading 60%. Should we be raising the humidity level? And if so, what are some good ways of raising it?
