New ball python. Is my setup efficient?

[yagirldani]

So i just got my first ball python about 2 weeks ago. She is so sweet and eating well. 2 f/t fuzzy for the past two Wednesdays. She has not shed since i have had her though. She is around 3 to 4 months old.
Right now she is homed in a 20 gal tank with screen on top. I have foil and wet paper towels covering most. I have a lamp but do i need it? I also have a UTH on the basking side which is reading on average 93. Humidity is at 57 and cool side around 80 (pics with exact below). Is there anything im doing wrong or anything i can be doing better to make her more happy?

Also i call her a she but i dont know for sure what the sex is i unfortunately got it from a pet store even though she seems to be doing okay so i guess im lucky.

Thanks in advance for any help.

You have the right idea. Just need to check a few things. How is your heat pad regulated? Also, ditch the analog gauge. Depending on your ambient room temps you might not need the lamp.

Yea i dont use the analog one just came with the tank. I had my digital them. from my bearded dragon. My heat pad isn't regulated by anything. I read about using a thermostat but couldnt find one at any local store around here so im going to have to order one online. I keep it pretty cold in my house around 75.

Thermostats are ideal, but a lamp dimmer can be used with an infrared heat gun to modulate the uth temps. It can't go unregulated or you risk burning the snake.

75 isn't cold for room temps. Take the ambient tank temps with and without the lamp. As long as you are mid to high 70s ambient on cool side you're golden.
