C.A.P. HUM-1 Humidity Controller 

The HUM-1 is perfect for orchid growers! 

The C.A.P. Humidity Controller is easy to use and ideal for indoor gardening. Simply set the dial at your plants' preferred humidity level and the HUM-1 controller turns your humidifier on or off as needed to maintain the set level.

Any equipment operating on 120 volts or less is compatible with the C.A.P. Humidity Controller. It carries a three-year warranty and is made in the USA.

Combined with the Sunleaves Hygro-Thermometer monitor, you'll not only control the humidity levels in your garden area, you'll also have a constant temperature and humidity readout on the Hygro-Thermometer monitor to fine-tune your growroom requirements.
