My hygrotherm currently reads the humidity in my pyxie's exo terra is 90%, it's programmed to maintain it at 80%. I know 90% is the max humidity these frogs can stand, so how do I lower it a bit? Days temps are low 80s, and night temps mid to high 70s (following Lija/Colleen's advice, that I've recently discovered). The humidity tends to reach higher levels at night obviously from the lower temps. Ventilation is NOT restricted in any way, substrate is fresh, replaced a couple of days ago, I don't even mist the cage anymore as the fogger takes care of the humidity on its own.

Only thing I can think to do is wait until the substrate starts to dry a little (by then it could be time for a another substrate change, which I do monthly) and the humidity therefore lower itself.
