SexyHero, what I use in my viv is eco earth its compressed coconut fiber expandable substrate. Just mix with water ring out and place in the viv. Its damp but not wet using this would bring up the humitity greatly. It will dry out after 3 weeks, but then all you do is remove all plants and your snake from the viv clear out anything but the substrate, then add more water to make it damp again. Cornsnakes love it because they can burrow in it very easily. I get it for $10 for three bricks, I only have used 2 of the three so far. Its been at least 6 months since Ive changed the bedding. I swear by this stuff that it is perfect. It give a more jungle feel to the viv.
