Wow. What a difference. Especially in the summer time. During the winter it can take 2-3 weeks to fill the unit when set to 50% humidity. During the summer less than 48 hours. Huge amounts of water are removed. I was amazed.
Most of my darkroom work is done during our long winters. So during the summers I now store all of my cameras and equipment in the darkroom to keep everything dry and fresh. Can't afford to miss any of the short periods of nice weather we are barely allocated around here.
