Increasing humidity without misting/fogger?

[thefourthbronte]

Hello, I've been a long-time reader of this forum, but this is my first post as a member. Over the time that I've been lurking, I've been generally impressed by everyone's knowledge, expertise and enthusiasm to help others, which is why this forum was the first place I thought of to help solve my problem.

I live in NYC where humidity levels during the summer are high, so I never have to worry about having to increase the humidity levels in my snake's enclosure.

However, now that it's getting colder and humidity is dropping, it's definitely becoming an issue. My general method is to use a spray bottle and mist a few times a day, which works extremely well, but here is where my problem lies: I'm a full time university student, and I can't stand at my snake's enclosure all day misting away.

I'm looking for a way to increase the humidity levels without a) misting (can't be there all day to mist) and b) using a fogger (simply because I can't afford one.) I've thought about a few ways to do this: maybe place his water dish above the UTH or under the heat lamp so the water evaporates? placing a damp towel in the enclosure? No idea if these ideas would work.

Help me out?
