With an increase in the legal use of medical marijuana throughout the United States, large scale production greenhouses and grow room facilities are coming online across the country. While it is relatively easy to grow cannabis in these conditions, air ventilation and circulation is critical for both the quality of the product as well as the prevention of specific types of molds and diseases on the plants.
Unlike some plants that do well in high humidity, low airflow, cannabis plants thrive when there are specific levels of grow room ventilation. At the same time, keeping the air moving without a substantial breeze the makes it difficult to control temperature and humidity at the different growth stages of the plants has always been a challenge.
The Destratification Fan Option
Rather than using traditional types of HVAC systems or large industrial fans that create a significant breeze in small spaces and not enough volume of air in large grow areas, growers are increasingly turning to destratification fans as effective grow room ventilation.
These fans are ceiling mounted and required no special ductwork or costly installations. Unlike traditional types of fans, they are not designed to create significant air movement, but rather to create air circulation to even out temperature and humidity. This provides a more uniform temperature and humidity level, while also keeping the air circulating.
Without the correct type of grow room ventilation, CO2 levels can build up around the plants. By using destratification fans as grow room ventilation systems, the is also eliminated, and when combined with temperature and humidity control, it leads to greater growth, better quality, and less risk of disease problems with the crop.
The added benefit of destratification fans over large HVAC systems solutions is the cost factor. These fans are inexpensive to buy and install, and the best quality fans use less electricity than a 40 watt light bulb.
