Cannabis & Grow Room Fans | Industrial Airflow for Indoor Grow Operations

Cannabis & Grow Rooms

Combat humidity, manage heat, boost plant strength.

Cultivate with Confidence

Proper ventilation is one of the most critical, and commonly underestimated, factors in cannabis cultivation. Without effective airflow, grow rooms can become breeding grounds for mold, mildew, and pests, putting your entire harvest at risk. That’s where Patterson Fan comes in.

Since 1989, we've been engineering industrial-grade fan systems that create ideal grow environments. Our cannabis-specific ventilation solutions deliver consistent airflow to regulate temperature, control humidity, and improve air quality, helping your plants thrive from seed to harvest.

Every cultivation facility is different, which is why we take a customized approach. Our team works with you to design a ventilation system that meets the unique demands of your space, whether you’re operating a compact indoor grow or a large-scale commercial operation.

Don’t let poor airflow hold your grow back. Partner with Patterson Fan for targeted, reliable solutions built to boost plant health, maximize yields, and keep your operation running strong.

Why Air Circulation is Key to Plant Growth:

Plants grown outdoors enjoy the mitigating effects of wind, sunshine, and precipitation. When indoors, grow lights and watering systems are substituted for daylight and rain. However, regularly disregarded is the need for wind or air circulation. There are many reasons to improve ventilation within your floriculture facility, fruit and vegetable greenhouse, indoor gardening operation, or cannabis grow room.

Control Climate

Cannabis grow lights produce significant radiant heat, and without proper ventilation, localized hotspots can stunt growth or stress plants. As plants transpire and ambient humidity rises, unchecked levels can inhibit nutrient uptake and promote mold or mildew. Targeted airflow and vapor control are critical for maintaining VPD balance, optimizing nutrient delivery, and maximizing yields.

Disease & Pest Prevention

Mold, mildew, and insects prosper in stagnant, humid conditions. Airflow from industrial fans creates a steady breeze, protecting against harmful mites, fungus, and diseases.

Strengthen Plant Growth

When grown outdoors, plants are subjected to the wind. As a result, their stalks become thicker and sturdier. Stouter plants grow better than weaker ones, which can break under the weight of their own yields. Airflow from industrial fans supports the necessary breeze for plant strengthening.

Increase Carbon Dioxide

Plants must absorb carbon dioxide throughout the day for nutrients. Poor ventilation decreases carbon dioxide levels, limiting growth capabilities. Industrial fans help move the stale air with ventilated, fresh air to improve air quality.
