You want to be sure to have at least 2 hides, one for the cool side and one for the hot side so he or she can thermoregulate. Balls will often stay too hot or too cold if they only have one hide as they are pretty shy...that actually goes for a lot of snakes. I don’t set any of my bp thermostats over 90F for the hot side, I usually aim for a high of 88F. My thermostats shut off the electricity to my rhp when the temperature reaches my allowed high temp, cutting on when it drops back to my minimum setting (I set a 5-6 degree range). If your tank is regularly hitting 95F requiring you to manually turn the lamp on and off, I would try a lower wattage bulb and invest in a thermostat. The thermostat will help maintain the correct temperature range without risking overheating your pet. A heat lamp over the water bowl will actually help boost the humidity, you’ll just need to check it regularly. I’d personally look to rinse and refresh the water daily, no more than every other day if it’s large enough to hold water that long.
