Hmm, of the given options I'd say under the leaves is "really damp." The top side of the leaf litter does dry out quickly, but it's never been dry underneath when I've checked. Also, I just took a temp & RH reading of the room the tank is in using the same Govee unit I have in the tank, and the readings are very close - maybe that's why I'm not seeing condensation?You've learned well .
@DontCallMeAToad : how does the substrate cell under the leaves? Is it dry, damp, really damp, fairly wet, or soaking wet? This is one way to tell how much moisture is in the tank.
In a top opening tank, with no ventilation at the bottom I would expect to see condensation on the glass of the humidity was in the 70-90% range (my only top opening tanks (for froglets) have condensation on the glass most of the time and I only mist then once a day, if not every second day).
