Humidity Question

[The Serpent Merchant]

I hope you are still monitoring this thread. I was thinking about getting the repti-fogger as well, but you suggest there are better/cheaper ways to increase humidity. I have a digital hygo on the way, to get a more accurate reading. However, what are those better/cheaper ways to increase humidity?

Changing heat sources

Changing cage types

Covering the screen top of a class cage

Changing substrate

Adding a humid hide to the cage

Getting a larger water dish (more surface area)
