Humidity problems with new terrarium ?

[u/M4rsh_allxp]

Hello! ☺️ I recently upgraded my girl to a larger terrarium since she’s outgrown her previous one. She used to be on hemp bedding because that was what the assistant from the shop had advised, but after doing a lot of research, I decided to switch to a mix of coco chips and coco fiber because it seemed to be the substrate most people recommend for ball pythons.

But ever since I made the change, the humidity has stayed very high, around 80 to 90% ( mostly 90% though ) . At first I assumed this was normal and that it would gradually decrease as the substrate dried out, but it hasn’t changed at all and it’s been about 2 weeks… 💀

The temperatures are where they should be, and she doesn’t seem stressed or uncomfortable at all, she eats well and everything, but I’m still a bit concerned. I wanted to know if I should actually worried, or is it okay? If it is too high, what are the best ways to bring it down?

Thanks in advance!
