I'm going to guess that Skull is a
BP???
Any ways, it sounds like you are using a tank with a screeened lid, so I will give some tips for getting the humids up to 70-75% for them.
You can put the water bowl on the warm side.
Cover the screen top with a moist towel, making sure it won't become a fire hazard (too close to lights etc.)
Cover part of the screen top with plastic wrap or aluminum foil, which will raise the temps a little bit, but as long as you don't go over 95f, it will still be fine for a python.
Mist the tank several times a day, if possible.
It sounds like the reptile humidifier was doing fine, but too small of a water supply, any way to increase its' capacity?
