Bit confused about humidity

[DanDrobates]

It’s normal to have fluctuations in humidity. Remember it happens naturally so don’t sweat it too much. The humidity will increase after lights out and vice versa. Ambient conditions may also affect it as well unless your frog room is climate controlled. Hygrometers are not always accurate and tend to stress the hobbiest more than the frog. Frankly I don’t use them for that reason. Your set up sounds perfect. Sometimes restricting ventilation will help retain higher humidity if you are that concerned. I use plexiglass or glass over the screen top to accomplish this. Remember red eyes are nocturnal. So as long as there is a more humid period during lights out you should be fine.
