This duct humidistat is a great solution to controlling the rH in your grow room. This humidistat features a 15–95% range with a 3–5% humidity differential. Simply set the humidistat to the desired humidity then this unit will take care of the rest by activating your humidifiers to maintain the selected moisture level. For best results, this unit should be mounted with the sensor unit in your air system's recirculation duct. This device performs most accurately at humidity levels over 70%.
