I "stumbled" upon Aspen Bedding and have found out how great it is as well.

If I need to get the humidity up in the cage I place an old towel across 1/2 of the top and mist that instead, and that helps solve my problems.

Another thing I like about aspen, is the odor control, (at least with the T-rex Brand Snake Specific Aspen), even if Nero happens to soil his substrate pretty thoroughly, which he has done on occasion, the aspen tends to control the spread of the excrement, which helps during spot cleaning and reduces the disgusting odor. Just my experience with Aspen.
