I own a jungle carpet python, 12X12X18in. I moved to Colorado, which has a lot less humidity than my snakes and I are used too. In her enclosure, I currently use forest floor substrate, a small water dish, and an imagitarium humidity gauge. I mist twice a week but can't seem to get the humidity gauge to read over 40. I did cover the screen top with tin foil as shown below and it helped but not as much as I hoped. Should I buy a larger water dish or is there something else I should do? I have read that JCP needs a humidity range from around 40 to 60, but from what my gauge shows that I am rarely not below 30. Any help would be appreciated.
