This affordable and highly effective humidistat is perfect for regulating and automating the relative humidity in your mushroom growroom or greenhouse. Simply hook your humidifier to it and set it to whatever relative humidity you want it to turn the unit on and off at. For example, you can have it turn on your humidifier at 85% RH then have it turn off your humidifier at 95%, the unit will then turn your humidifer back on again once the RH drops back down to 85%. Besides complete automation, another key advantage of using a humidistat is that it allows you to control the humidity differential. This means that this unit will allow for the evaporation of humidity before kicking your humidifer back on again. This is extremely important because evaporation is an important pinning trigger. You will need to have some basic knowledge of wiring to hook this unit up properly, as it requires you to hard-wire your control devices to the unit.
