Low heat and high humidity

[hermiesandrocks]

I’m trying to get my main tank stabilized, but I’m having difficulties with heat and humidity.
I’m concerned about mold growing before I even get the hermies in there. (Purple Pinchers)

The environment:
20 gal tank
7-8 inches 5:1 play sand/EE substrate with sandcastle consistency. (I’ve actually built a turtle just for fun, lol)
2 EMPTY bubbler pools (I haven’t added water yet, but the humidity is so high!)
I have a dry moss pit on the 2nd level
Ultratherm mat above the highest point of substrate and across the length of the back of the tank. I insulated it with Reflectix.
Fully sealed tank lid
Blanket folded on top
I use an Accurite digital thermometer/hygrometer.

I haven’t misted anything.

That’s everything that affects heat/humidity.

The current reading is 92% humidity and 77 degrees.

What, if anything, can I do to get the environmental conditions better?

That sounds pretty good. If you don’t want your humidity that high you may have to lift the lid once in a while to encourage air flow

And the humidity being that high without water will be ok? Thank you so much! It’s currently at 93% and 79 degrees.

It can never be too humid for crabs. My humidity levels in both of my tanks is usually 90%-99%. You may notice more mold growth on food or decor, but that isn't harmful to the crabs.

Good, I’m glad it won’t harm them. I guess I don’t mind a little hard work every now and then.
