I recently bought a fogger for my pacman Squish. It works great! The only problem is once I turn it off, the humidity tanks back down to the lower 60's or high 50's.
When I have it on the lowest setting, it doesn't seem to overwhelm the terrarium with fog, just a light layer. Do you think it would be safe for Squish, the fogger, or the overall condition of my terrarium if I leave it on this low setting for a long period of time?
