I'm sure there is a thread addressing it somewhere but I looked for a little bit then got lazy and decided to start my own. I use Aspen right now and mist to keep humidity up, but it's still lower than I think it should be (about 50%) so I was going to switch and try the eco-earth bricks that you soak in water. I'm just a little concerned that it may be too moist. I've never used it so I really don't know, but it just looks that way. Anybody have any issues using it? I watched a feeding video one time and it looked like the snake was eating a lot of the substrate along with the mouse!
