New White's Tree Frog Setup Question

For your humidity issues it just might be the gauge. Analog have a tendency to not be very accurate, and you can get a bad digital also, so I would replace your gauge and go from there. Can't see how your levels can be so low yet mold is growing.

I don't disagree with the analog hygrometers being off. However 4 to 6 hours of humidity per day in a 24 hour period is enough time to show a mycelium mass on a grapevine branch. All this mold needs is that time window for the spores to create the mycelium mass and then its a rapid growing problem as long as the humidity is above 45 percent. This particular mold will remain dormant on the wood pieces in humidity of 20 percent but as soon as she mists it will reproduce rapidly.
