How should I increase humidity

[KMG]

My problem is that I have to use heat lamps in order to keep the tank at the right temperature but that drys out the humidity. That's why I was thinking a fogger might be good? If my room didn't get so cold I probably wouldn't have this issue. The heat pad I have doesn't warm up the tank much.

I like it cold at home. At night my A/C drops to 64. When I lived in an apartment and had snakes all over my Ball was in the living room. Because of how cold I kept it I needed a 100che and a 60watt bulb to give me good temps. With that I made that cutout I mentioned earlier and added moss to the hides. I would only mist when the snake started a shed and all was good. Since the snake stays in the hides most of the time the high humidity in there proved to be enough for me.
