This is all new to me!! I have a baby rosy boa who is supposed to have very low humidity and now a baby corn that is supposed to have humidity in his cage. they are both kept in the same room. HOW do I raise the humidity in the corns cage? It is a 20 gallon tank with aspen on top of a piece of indoor outdoor carpet. The hot end is about 85 degrees and the cool end 73 right now. I have a bowl of water in the cage, but the humidity gauge is regestering 0% humidity. What do I need to do? What percentage should the humidity be? Thanks SOOOOO much. connie, balboa (the rosy boa) and Stalker (the corn snake)
