Three Considerations for Successful Cannabis Grow Facilities

If you have a commercial cannabis facility, whether it be for medical or recreational purposes, it is vital that it is closely controlled and monitored to maintain optical growing conditions. Therefore, it is important your HVAC (heating, ventilation and air conditioning) system is tailored to the facility’s unique environment. Arpi’s North is a leader in HVAC systems for closed environment greenhouse cannabis production. In this blog, we share three points to consider for a successful operation.

Temperature and Humidity

Temperature and humidity are key components for cannabis grow facilities. By regulating temperature and humidity levels, HVAC systems help to create a stable environment in which plants can thrive. The system should be able to effectively remove heat and humidity from the air while maintaining a consistent temperature.

The ideal temperature for cannabis plants is between 70-85 degrees Fahrenheit (21-29 degrees Celsius). Too much heat can cause the plants to stop growing and even die, while too little heat can inhibit the growth of helpful bacteria and fungi. A properly designed HVAC system can also help remove any excess heat generated by lamps or other equipment, preventing the facility from becoming too hot and compromising the quality of the plants.

In terms of humidity, the ideal range is between 60-70 per cent. Cannabis grow facilities require a high level of humidity control to produce optimal yields. However, it’s a delicate balance; too much humidity can lead to problems such as mold and mildew, while too little humidity can cause the leaves to dry out and become curled.


Cannabis grow facilities typically have higher airflow requirements than other types of buildings, so it is important to choose an HVAC system that can meet these demands. Ventilation is also closely related to heat and humidity: by providing a steady supply of fresh air, ventilation helps to keep temperatures and humidity levels within the ideal range, allowing the plants to thrive. Proper ventilation also circulates air and keeps the grow facility clean and free of mold and mildew spores, which is important as mold and mildew can quickly spread and destroy an entire crop – and your investment. Ventilation also helps to remove carbon dioxide and other pollutants (and odours) from the air, providing the plants with clean air to breathe.

Unit Size and Quantity

When designing a cannabis grow facility, HVAC unit size and quantity are a critical component to a successful operation. The size and quantity of HVAC units are determined by the size of the facility and the type of growing operation. (A small indoor grow facility will require less ventilation than a large outdoor grow facility.) Additionally, the type of growing operation will affect the HVAC requirements, with hydroponic grow operations requiring more humidity control than soil-based grow operations. Once the size and type of grow operation have been determined, the HVAC system can be designed to meet the facility’s specific needs.

A properly designed HVAC system is essential for any cannabis grow facility to produce high-quality crops. By working with a professional HVAC contractor, you can select the perfect system for your cannabis grow facility and ensure your plants always have the ideal growing conditions.
