As I mentioned earlier...spritzing it with water when you mist the enclosure is alright. But truly wet bedding...of any sort...will harbor/breed tons of bacteria and that bacteria can get under the snake's scales and cause infections. There are ways of keeping the humidity at the proper levels without restoring to wet bedding.
Someone might be able to get away with it for a time, but eventually, scale rot or other similar infection will rear its ugly head.
