I just bought a CHE today with a lamp and a stand (WHY ARE STANDS SO EXPENSIVE!) as my temps were too low after running the UTH for about 24 hours. also i was originally using newspaper for substrate, swapped to half eco earth and half reptibark and that helped my humidity alot. my humidity is sitting at a solid 60, i just need to get my temps up higher. For reference pre-CHE i was sitting at about 76 cool side and low 80s hot side. its too low. i'll see where everything is at after i get home from work with the CHE and see if its going to be enough of a difference or if i should return the glass and swap to tub.
i may also just throw my space heater in my room and call it a day, idk lmao
