Everyone is talking about moist hides (I call it a shed box) and whatnot, so here are my instructions for making one (copied from another of my posts on shedding):
1. Find a suitable container, with a lid. The size should be just like hide. It should be not to large for your corn, but not too small. Making it too large will make it feel less "safe" to a corn, and making it too small will be uncomfortable or hard for the corn to use. I would suggest using a translucent or opaque container to make the snake fell secure. If you have a perfect clear container, then I would suggest covering it up with substrate to block some light. Also, using any material like cardboard, paper or anything of the like will absorb water and is not much of a good idea. I don't see paper like material being bad if you need something disposable for the week that your corn is shedding, but I like to keep the shed box and re-use it. The lid is necessary to hold in the humidity. If you find the perfect container, but don't have a lid, you can probably make one.
2. Find a suitable interior "substrate" for use in the shed box. I use cut-to-fit (not shredded) paper towels, as they are cheap, and i always have them, but I have heard of spaghnum moss being useful as well. Using a substrate like aspen isn't going to do you any good, it will lock in the moisture you give it, but will not let it out in any useful way.
3. Cut a hole in the side of the shed box big enough to easily allow the corn to enter and exit, yet not too big, as it will let out excess humidity. Also, if you are working with plasic, beware of sharp edges from the cuts.
4. Fill the shed box with your substrate of choice, and put the lid on.
Congrats, you have a shed box. I would suggest making two, placing one on the warm side and one on the cold side of you tank. The first shed I had with my corn was horrible. The shed was not anywhere near complete, and had to be manually removed in some places. The next shed I put two shed boxes in and what do you know, my corn had his first perfect shed.
Hope I helped,
