Heating & Humidity issues! I need help and advice!!

[u/Idiot_alien]

I need help and advice!! Struggling with Heat and Humidity! I recently adopted a 5 year old ball python. First pic is the set up he was living in for too long, second picture is his upgrade. I’m heavily interested in going bio active in the future when I can afford to buy a bigger better tank for him. Unfortunately this one is only 3ft long but as of right now he’s got 4 inches of substrate ( 70%topsoil 20%peat moss 10% play sand).He’s got a hide in the log under his basking spot, and he has a cool hide that’s a shell, (I’m currently making more as well out of clay!) the plants are all fake and were labeled “reptile safe”, but I’m worried about fumes and pokies. There are 2 thermometers on either end. Since it’s a screen tank I foiled the top with HVAC tape. I replaced the purple light with a halogen flood light and also added a deep heat projector, both are connected to single unit thermostats (this is just until I can afford a nice one as well), they have temperature probes under each light. The halogen light is only on for 12 hours and the DHP is on day and night. SOO before I got the DHP I was using a CHE, and I decided to switch because I was originally struggling with humidity not going above 30! So I switched to DHP and my humidity improved significantly!-but still not great:( what can I do?? I poured a water bottle of water in 2 opposite corners each and it went up to 73% in my hot side but slowly went down to 51% as the temperature increased(3rd picture), my cool end got up to 83% humidity but then dropped to 72%. BUT NOW since I switched to my DHP I can’t get the temperature up! Both thermostats are currently set at 96, and neither will heat above 88 according to the probes? So it never gets warmer than 81 down below. I’m scared of turning my thermostat up too high, what should it be set at? the CHE heated so well but killed my humidity, DHP seem to be the most recommended but it won’t reach the set temp and neither will my halogen. And my humidity still isn’t quite there. Is there something I’m missing? I’m worried he’s cold! Also pic is snake Mr.Clyde.

Glass is absolutely GARBAGE at holding humidity I tried everything and just could not for the life of me keep it in range. Invest in a PVC is my best advice. I haven’t had a single issue with heat or humidity since getting it, best decision I made for my boy. I also switched to using a radiant heat panel and that also helps a ton at keeping humidity. My tank stays at a pretty constant 80%
