For awhile now I have not been able to keep my ball python's tank at a decent level of humidity, and I have been using a humidity box. The humidity box works perfectly fine. I have never had problems with shed since I have started using it, but I know that most people believe that ball pythons should always be in a humid environment so I would like to finally figure out how to increase humidity.

My room tends to shift temperature a lot and often it gets too cold. I have a heat pad but it doesn't keep the tank warm enough, so I have to use two heat lamps. One on either side of the tank. The heat lamps of course dry out the tank plus the tank has a mesh lid.

I use eco earth with a little bit of repti bark as my substrate, and he has a water dish big enough for him to sit in.
I have tried misting the tank with a spray bottle but I'm not always around to do that. I've tried covering part of the mesh but because of the heat lamps it doesn't help much.

I was thinking that getting a fogger of some sort would maybe help, but I wanted to ask before buying one. I've heard that foggers can sometimes cause too much humidity for a ball python, but I was thinking that because of the situation that I'm In this would maybe be a good solution?
Thank you so much for your time and advice.
