Maintaining Humidity

Because of the other recent topics bouncing around the forums right now, I've decided to post about methods to deal with LOW humidity?

I've heard of using damp paper towels to help keep things humid. I myself use a spray bottle to keep things damp to raise humidity levels. As well as putting heat lamps over water bowls and such.

Any other interesting or clever tips anyone uses to help keep things nice and comfy for their snakes?

Simplest one I can think of is to avoid using the screen lids that were originally designed for rodents when housing reptiles. Your always going to be fighting a losing battle with that much screening.

1) Large-wide water dish: wide surface area promotes greater evaporation
2) Water dish over the heat source: also promotes evaporation
3) If you have a screen top: You can cover 90% of the screen with a damp towel, tin foil, or plexiglass
4) Use a substrate that retains moisture: Coco-husk or Cypress mulch
5) Stop using heat lamps. They destroy humidity and make things very dry.

Instead of fixing the entire enclosure, just provide your animal with a "Humid Hide".
Get a tupperware container with a lid and cut an entrance hole into it. Place damp paper towel or damp moss inside. This creates a humid micro-climate that the snake can choose to enter when it needs humidity.
