I have packing tape on the adults lid and saran wrap on the baby's lid.

It is cypres mulch and dries out over the course of 2-3 days, especially if I churn it once a day.

It only stays at 80% for a day and drops to 70% then 60% over the next 2 days. the bedding isn't wet when we use it, just damp. Like a rain forest floor.

We have used the bedding with the adult since June with no issues. Just noticed there was a bit of condensation from the dampness and heat in the tank in the baby's tank this time. It goes away within a day. Just wondering if the openings around the lights are enough for air flow.
