Hi everyone, I'm looking for advice and options for keeping the humidity up in my ball's tub enclosure! I've read some conflicting information - that humidity should be around 80%, but also that good airflow is needed and that soaked substrate can cause problems - and I'm not sure how exactly to achieve that. Proper ventilation seems to drop the humidity too fast, and misting/spraying isn't doing the trick.

Does anyone have any tricks or methods they like for keeping humidity where it should be?
