Help with Himidity levels.

Hey all! I have a cute little ball name Monty. My problem is, her humidity levels in her enclosure. I think the reason for this is that her tank is too big. It is a 36x17x18. I know this is way too big for a ball but it is all I have for now. Everything else in the enclosure is perfect for her. I have an undertank heater with a thermostat. The hot side of the tank is perfect temp and the cold side is a perfect temp. She is about to shed and I am constantly having to spray to keep the humidity levels between 50-60% as I have read that this is prime himidity for a good shed. My question is. Are there any tricks that I dont know about that can help maintain these humidity levels without having to spray her tank all the time? All this spraying, I am worried, is stressful to her. Are there any types of devices that I can buy to put in here tank to measure and automatically keep the humidity perfect? I also forgot to mention that I have used Tin foil and and duct tape on the top of the tank. I read a DIY on this site from someone about using tin foil for keeping heat and humidity in. I have 2 6x6 holes cut out in the top for ventilation and when she goes through shed, I cover one of them with a towel to try to keep in as much as I can. Any pointers from anyone would be greatly appreciated. Thank you all in advance for your help. Have a wonderful day!

smaller enclosure first, bigger water bowl, moving water bowl towards warm side, less ventilation. certain substrates can help too

Yeah, I do need a smaller tank but I am looking for something that I can do for the tank I currently have. For now. I will make my air vents on top, smaller. Thanks for your input. :)

You've pretty much covered everything.

What substrate do you use?

I recently put cocohusk with one of my guys and it has too much humidity with the tin foil, and I'm in a reallllly dry place.

You could also try replacing all the tin foil with a damp towel.

I house my BP in a 30gal tank with a screen top, I had a major humidity issue too. What I did to fix it was cut out cardboard panels, covered them with tin foil and place them on top of the screen top. I cut them so they fit perfect on top, with a space for ventilation. Its nice because you can move it around as needed to raise or lower humidity.
I also use sphagnum moss and wet it, put it in a small glass dish on the warm side. This helps it evaporate and gives off humidity. I also have a big water bowl. When my BP is in shed I will moisten some moss and place it in the hide with him (not sopping wet, dont want any scale rot or anything). This has worked amazingly for me since I started doing it and I've had perfect sheds ever since!! Good luck!

Also, I've done this with two types of substrate, reptibark and on paper towels, worked great on both.

thanks for the info all! I will try all of the above :bow:
