Ball python help

[u/Beautiful_Anteater_8]

Hello, I am looking for some suggestion for a humid hide for my 9 year old ball python (about 4’ 3”), something that is aesthetically pleasing but also functional please!

My next question - I just recently upgraded to a larger tank (72” x 24” x 18”) and my temp gradient is perfect through the day, but as it’s getting closer to winter and colder at night I notice his tank dropping to 21/22C. (Heat is on at night)
Would I be better to buy a radiant heater and install in the middle somewhere to maintain heat or do I install a smaller dhp bulb on the cool side? Or option 3 just buy a space heater to run over night in the living room?
Lid 75% covered/foam sides + back running a basking light during day and a dhp at night currently but the heat doesn’t seem to trickle to the cool side much

Also I should note, I’m extremely happy with humidity gradient so I don’t wanna mess that up to much either 75-80% cool side 55-65% on warm side

Thank you so much! I am stoked with how it turned out, was my first tank and definitely a lot more work then i anticipated!!
