I used to house all my snakes in separate bins scattered round my room. I used astro turf for a while but it got difficult to see when they peed on it. It was black turf. Then I switched to paper towels for the whiteness of them and the cheapness. They are working ok but I'm having a bit of a problem keeping humidity up in the bins. I have a rack system set up with 28 quart sterilite bins and back heat. I'm wondering if switching to cypress mulch will help hold humidity better than the paper. Or if any of you guys have other solutions I would be happy to take them into consideration as well. For right now I have been misting every other day or so which I'd fine but gets annoying after a while. If this is the only solution then I will have to live with it but I'm open to ideas. Thanks guys.
