You could, or you guys save yourself $50 and get a tub

Ball pythons don't need a TON of humidity. Misting systems are used more for amphibians, chameleons, and other animals that require high (90+%) humidity or moving water to drink.

Ball pythons really only need 50-70% humidity which is easily accomplished with a daily spray. If you use a heat lamp with your tank you will notice a huge drop in humidity, so if you don't need one don't use one. Cover your screen top with something that will act as a moisture barrier. I like to use pieces of acrylic because I can still see through it Just leave some sort of gap for ventilation.
