I would first say read the Ball Python care sheet as this will answer most of your questions.

The temps should be 82-83 on the cool side, 92-93 on the warm..your humidity should be 60%. The hides should be enclosed and small and tight...that is how they like it. You can just get plastic bowls or etc. cut a hole and burn the edges so they are not sharp. You will need 2 one on the cool side and one on the warm side. The screen top is going to be difficult to keep in the humidity. You can get a piece of plexi-glass to cover it up or you can use aluminum foil. Otherwise you are going to loose all of your humidity. The heating pad....please be sure it is an under the tank heater...needs to be on a thermostat to control it otherwise it could get too hot. You should also have 2 thermometers...with probes...one for each side. (you can get these at wally world) also you need a hygrometer to measure your humidity. If your under the tank heater works enough then you should not need your light. BP's do not really need a light cycle....and the light will further hurt the humidity. If the UTH is not working to capacity I would get a bigger one....but again it will need to be controlled with a thermostat.

Also I don't think I read what you are using for susbstrate (stuff on the bottom of the cage)....please see the care sheet as it will list what you can and cannot use.

Once all is set up make sure that you leave your snake in there for about one week....with no touching. (trust me this is the hardest thing to do) but it will help her adjust and to get acustom to her new digs.

Congrats and enjoy your new snake.....care it becomes an addiction so quickly. By the way welcome to the forum....you will find that everyone is awesome on here and really really help so much!!
