Too humid?

Hiya! I am new here! I had crabbies as a child but recently purchased them in October of 2019. Over the past few months with them, I have finally got their tank to where it is in pretty great condition. Only thing is, their humidity is always above 90%. I don't spray often. I do have large water dishes though, but am I hurting them? Over the past months, I've spent several hundreds of dollars on all of their supplies to ensure I'm doing my best for them, but I am stuck here. Help!

Have you calibrated your hygrometer?

Otherwise, 90% RH and above is perfectly safe. Mold grows more easily but the hermit crabs will be fine.

Yes, it's calibrated. And I have more eco earth than most people have in their tanks but I also have springtails for some cleanup crew! Haven't had any mold issues so far! Hoping it stays that way haha

My humidity almost always runs at 90 (right now in winter it's so dry on the Canadian prairies) and above. I haven't had huge problems with mold. There really isn't any such thing as 'too humid', it's fine for the crabs.
