Set-up Questions

[CALM Pythons]

i got my first ball python almost a week ago. i feel like i'm doing this wrong, so here goes.

using a large (too large - looking to transfer to a smaller one) tub filled with plenty of stuff for a baby bp.

warm side:
- hot spot temp is 92 degrees. the thermometer is measuring underneath the substrate
thermostat is set to 106. heat pad is on the outside. thermostat probe is in between the heat pad and the tub.
- one hide

cool side:
- ambient temp is 75 degrees. the thermometer is measuring the air.
thermostat is set to 104. heat pad is on the outside. thermostat probe is in between the heat pad and the tub.
- one hide
- water dish

in the center there are some plant decorations to fill up the space.
humidity is currently at 72% (my bp is going to shed soon)

i need help. i don't know what the most efficient way to correct the temperatures for this. where to put the thermometer probe, whether the temp is ambient temp or hot spot temp, why i need to set the thermostat up so high to get a temp so low, etc. i followed some guides on here but it feels like it is not working out for me. help would be appreciated. thanks a bunch.

pictures will be posted if necessary asap

If im understanding this, your running 2 UTH's? One is on the Hot side and its 92 and the other is on the cool side and the ambiant temp is 75? Is this what your saying? If so, the UTH on the cool side is much warmer on the Floor than the Ambient temp of 75 so there goes your cool side as its almost the same as your hotside Belly heat...
When we are talking about a ambiant temp its usually done with a RHP or a Ceramic heat bulb or heat lamp. Your snake really doesnt have a cool side unless he is hanging from a branch as the Belly heat is hot on both sides....use one Heat Lamp or Ceramic for ambiant and one UTH for hot basking.
(Unless I read this all wrong which is possible, if so im sorry im tired)
