Required?

[Ratmosphere]

For tarantulas that require high humidity, is it required to have a substrate consisting more than coconut fiber and sphagnum moss? An example would be coconut fiber and sphagnum moss mixed with vermiculite.

I think the cocofiber and moss would be fine. I dont put moss in the cocofiber, I just glue it around for decoration and added humidity.
