100% Secure PaymentsTake Control of Your Growing Environment!
Many factors go into making the ideal grow room or horticulture space. Lighting, soil conditions, fertilizer, and many other factors all must be considered. But one of the most critical aspects to creating the perfect indoor growing space is generating air circulation. Air circulating fans are the perfect solution to replicating wind conditions plants would naturally experience in an outdoor environment.
Why are air circulating fans necessary for grow rooms?
Heat: Indoor grow rooms often make use of high-power lamps that mimic the sun. These lamps are necessary for photosynthesis. However, these lamps also give off an excessive amount of heat, leading to potentially oppressive conditions for humans and plants alike. Air circulating fans create a cooling affect that makes conditions much more comfortable and ideal for growing conditions.
Humidity: Plants give off moisture, increasing the humidity in indoor horticulture spaces. Just like how air circulation creates a cooling effect, air circulating fans also mitigate the effects of humidity.
Deter Pests: Airflow around your plants helps to deter harmful pests like gnats and mites, and control rot, powdery mildew, and mold.

Dust: In indoor growing environments, dust can easily settle on plants, blocking the pores on a plant’s leaves and making it difficult for the plant to respire. Air circulation in an indoor growing space will prevent dust from settling on leaves.
Plant Strength: In their natural, outdoor environment, plants are constantly being buffeted by the breeze. This leads to stronger, healthier stems, which in turn makes the plants more fit to bear weight as they grow. Air circulating fans replicate the workout your plants would receive from the breeze!
What fans are best for grow rooms and other indoor horticulture spaces? That depends on the size of the space.
Small to medium size grow rooms
For small to medium size grow rooms (the kind most people would have in their house), we recommend Jan Fan Industrial Air Circulators. Jan Fan started way back in 1958, and quickly grew in popularity in the automotive industry in Detroit. For that reason, you can trust that Jan Fans are durable as well as functional. Jan Fans are available in a variety of sizes and mounting options.

All Jan Fans are available in silver and safety yellow. Let’s go through some of the options that are best suited for indoor growing spaces.
Jan Fan Industrial Air Circulators can be mounted to the wall and pointed toward a specific area of your growing space.
