So I redid Ernie's enclosure again because I added some things, took other things out, and needed a way to keep humidity up on one side, and a way to keep my log hide from going moldy from moist substrate. I've been experimenting with a humid side/dry side and so far, so good! Ernie happily moves from one end to the other, in and out of his little tunnels =] He loves the addition of the new log hide, and climbs up and over it all day. I mixed the coir/sand on the dry side with some cypress mulch, and mist it lightly to keep it from being dusty. The humid side has strictly coir/sand mix, and is misted and water much more often to keep humid. I keep a lid on the humid side to help hold in moisture, and it has done a great job. Here are some pictures, let me know what you guys think.
