We live in a climate with very dry and hot summers, so I have to manage humidity very closely. This gizmo is a Mist-O-Matic, it is the most simple humidity controller I could find. When the water on the screen evaporates it teeters up and a mercury switch activates automatic irrigation valves that run the mist system. It's very old technology, the greenhouse at my high school in the 70's had one. I'm just not very good with those high-tech humidity/CO2/irrigation/pasta makers that Hydro Farm and the "Grow Room" folks like to use.
