keeping humidity up

[LLinz]

This question gets asked a lot, I thought it would be good to have a thread for people to post their ways of keeping humidity up.

I have a glass tank with a screen top. I put a big water bowl above my UTH, and I covered most of the screen top with heavy plastic.
Also, I mist heavily and stir up his substrate daily. And I use coco husk and repti bark as a substrate, the coco husk holds humidity well.
When my BP is shedding, I put a fountain in his tank which he likes to play in and I find that it helps up the humidity.
Any other tips and tricks?
Of course a wooden enclosure is best, but a lot of people do use glass ranks.
