Son getting ball python. Cage setup help please

[I<3Dreamsicles]

the flukers is sitting above the substrate

The acu rite box is on the right side of cage.. the probe is on the bottom glass above the UTH under the substrate

So the flukers one said 83 or what ever... Like I said just go with the Accurite. The temp probe is the temp you want to watch because they can burrow in the substrate and if its to hot on the glass they can get burnt. The substrate will be warm enough if the temp probe says the correct temp range.
