Today's indoor agriculture and cultivation grow rooms require industrial grade HVAC systems to ensure the right climate conditions are available to the plants at the right time. Temperature, humidity, and CO2 must be maintained despite constantly changing conditions inside and outside of the grow room to ensure a healthy crop.

Pathogens, pollen and mildew must be continually removed from recirculated and fresh air to comply with states' ever tightening regulations. These mechanical systems must be controllable, both at the unit and remotely via the web, for scalable multi-room and multi-location operation. Sierra, a Mestex brand, has assembled a line of state-of-the-art mechanical systems that are controlling the climates of award-winning indoor agriculture grow rooms and green houses nationwide.
