It has now been four hours and it seems to be holding at 70 percent after moving the screen.

Lesson learned... don't monitor the humidity at the ventilation side. I'm sure my Whites are doing well since all are hunting, being vocal, and enjoying the three water spots that are provided.

I'm still thinking on the fogger since I plan to set up another viv and not sure if its doing to be darts or a pair of Red Eye Tree Frogs. This morning I'm heading out for a 18x18x18 enclosure and the bottom layers of substrate.
