To much humidity

[jeff68982]

Anyone recommend a substrate that doesn't hold humidity? My tubs in my rack have very high humidity have holes down both sides and still drenched inside currently using cypress mulch

Dry out the cypress mulch. I have a large tub I keep full of cypress mulch. I use Forest Floor which comes very damp. I put it in the large tub and stir it every few days to let it dry out.
