Update. Just shy of one month in use with animals and 2 months since completion and testing started and all is going great. I never need to mist. Every 3 to 4 days I take a few handfuls of water from the water bowls as I change it and splash it around the enclosure getting substrate, rocks and vines a bit. I then mix around the wet spots of substrate so they aren't wet spots and that's it. Humidity raises to about 75% and drops to around 55% in 4 or 5 days or so. Temps have been holding solid. No mildew or mold forming that I can see when checking and spot cleaning. So far so good. I am happy with the results.
