I just set up my new tank for my 2 year old, 2 foot long Ball Python, Slithers. However, I live in a naturally humid area, where the interior humidity rests around 50%. When I raised the temperature in my plastic tank to 75, the humidity inside the tank shot up to 80-90%. I used the soldering iron trick to make 1/8 inch holes every 2 inches on the length of the tank, but I'm guessing it doesn't let enough of the humidity out.

I'm worried about making more holes in the enclosure, because the interior of my house is around 68 degrees, and the tank does not seem like that good of insulator. I have a larger water dish that is big enough for the snake to soak in, and keep it around an inch deep.

Any suggestions on regulating the moisture content?
