Mushrooms require a constant supply of fresh air to maintain their metabolic processes. A proper ventilation system is essential for cultivating mushrooms, as it ensures optimal air circulation and prevents carbon dioxide buildup, excessive humidity, and poor mushroom formation. One of the key components of a mushroom ventilation system is the fan, which helps control air circulation and maintain a stable microclimate. The fan's speed and placement can be adjusted to influence the activity and growth of the mushrooms. Upgrading to a more efficient fan or incorporating additional components, such as ducting, humidifiers, and exhaust fans, can further enhance the mushroom growing environment.

Fan placement
When placing an exhaust fan in a mushroom growing room, it is recommended to install the fan near the ceiling. This placement ensures optimal airflow and CO2 removal. The airflow from the nozzles hits the floor and rises between the mushroom blocks, effectively picking up CO2 and removing it through the exhaust. Placing the exhaust fan near the floor is less effective, as the airflow does not adequately capture the CO2 around the growing clusters.
In a mushroom closet grow setup, the fan should be placed near the ceiling to facilitate the exit of stale air through ducting. This setup ensures an even spread of high-quality air throughout the room, benefiting mushrooms at various shelf heights. Proper ducting and vents are essential to distribute fresh air evenly and prevent stagnant pockets of air that can hinder mushroom growth.
The FAE fan, designed for floor placement, should be connected to the port located at the bottom of the BoomRoom tent. The on-unit controller allows for easy adjustment of fan speed, and the extra-long cord provides flexibility in fruiting chamber placement.
Fan settings and speed are also important considerations. During periods of high activity, such as mycelium growth and the first flush, a higher fan setting is required. The higher the fan position and speed, the more circulation is provided, resulting in increased cooling. Later in the cultivation process, after the second or third flush, the fan setting should be gradually reduced at regular intervals to allow for more control over mushroom growth.

Fan speed
The fan speed in a climate control computer can be set based on factors such as compost temperature or the position of the fresh air inlet. Adjusting the fan speed has a direct impact on other factors in the growing room. For example, increasing the fan speed with the same fresh air inlet position results in a higher intake of outdoor air. Similarly, a higher fan speed with the same cooling valve position leads to reduced cooling, while a higher fan speed with the same heating valve position results in decreased heating.
It is important to monitor the conditions in the growing rooms in the morning and evening to ensure that the fan speed is set appropriately. Additionally, the fan speed can be adjusted to influence the activity level of the mushrooms. Activity, which is the difference between compost temperature and air temperature, is the main energy source for mushroom growth. By increasing the fan speed, there is more circulation in the growing room, providing additional cooling. This higher fan setting is particularly beneficial during mycelium growth and the first flush, when there is typically more activity.
To prevent issues with fan speed fluctuation, it is recommended to use a proper speed controller suitable for the type of motor in use. For an AC motor, a variable frequency drive is the appropriate method for controlling fan speed. This helps to protect the motor and ensure its longevity. Additionally, ensuring a constant supply of fresh air is critical for mushroom growth and fruiting. A Fresh Air Exchange (FAE) fan can be used to control CO2 levels, promote airflow, and maintain a stable environment for mushroom cultivation.

Waterproof fan and ducting
For optimal mushroom growth, it is important to ensure a constant supply of fresh air to maintain metabolic processes. A waterproof fan and ducting system can help achieve this by facilitating air circulation and preventing stagnant pockets of air.
A waterproof fan is connected to a water reservoir through ducting. Cool air passes over the water, collecting moisture in the form of mist, and is then mixed with the air in the room. This helps maintain the desired humidity levels for mushroom growth. The ducting allows for the even distribution of air, ensuring that mushrooms at both the bottom and top of the shelves receive a quality atmosphere.
When choosing a waterproof fan, it is important to consider factors such as air flow, rotational speed, noise level, energy consumption, and ease of installation and maintenance. There are various manufacturers that offer waterproof fans, including PLYMOVENT, Fandis, Dantherm, and Honguan. The Honguan PowerDual P3, for example, is a 3-inch inline duct booster fan that operates at 9000 RPM with low noise and energy consumption. It is made from durable, corrosion-resistant plastic and features speed control for customising airflow and noise.
In addition to the fan, proper ducting is crucial for effective air distribution. Ducts and vents should be properly sized to ensure adequate circulation and prevent stagnant air pockets. Duct clamps and "S" rings may be required for installation, depending on the specific fan model. Regular maintenance of the ducting system is also important, including cleaning filters and checking for blockages or wear and tear.

Humidity control
Water Reservoir with Fogger
A water reservoir with a fogger can be used to create a humid environment for mushrooms. The fogger releases a fine mist into the air, and the humidity level is controlled by a humidistat. When the humidity drops, the humidistat activates the fogger to release more mist, ensuring a continuous supply of moisture. Conversely, when the humidity rises, the fogger is shut off. This system helps maintain the ideal humidity levels for mushroom growth.
Mushroom Exhaust Fan
A mushroom exhaust fan is essential for humidity control. It facilitates the removal of excess humidity and carbon dioxide from the fruiting chamber, aiding in moisture level control. By adjusting the fan speed and settings, you can influence the activity and cooling in the growing room. Higher fan settings are recommended during periods of high activity, such as mycelium growth and the first flush. Gradually reducing the fan speed after subsequent flushes gives you more control over mushroom growth.
Martha Tent Humidifier
A Martha tent humidifier can be added to your mushroom growing setup to enhance humidity control. It helps maintain the balance of fresh air, humidity, and temperature, creating an optimal environment for mushroom growth and development. With the ability to accurately adjust humidity levels, you can cater to the specific needs of different mushroom varieties.
Automated Fanning and Humidity Kits
Automated fanning kits, such as the Gorilla Mushrooms™ Universal Automated Fanning Kit, eliminate the need for manual fanning. These kits provide automated ventilation, allowing you to set custom ON/OFF settings and timing. When paired with a humidity kit, such as the MycoMIST™ Humidifier Upgrade Kit, you can automatically reset humidity levels and promote larger mushroom yields without the need for manual spraying.
DIY Solutions
For a DIY approach, you can create a simple humidifier for your mushroom fruiting chamber. This can be achieved by attaching a mini-humidifier, which can be set on a timer or controlled with a humidity controller, to your setup. Additionally, spraying the sides of the chamber with a fine water mist once or twice a day can help increase humidity during dry months.

Airflow patterns
Exhaust Fan Placement: The location of the exhaust fan can impact airflow patterns and the effectiveness of CO₂ removal. Many growers believe that CO₂ accumulates at the bottom of the grow room. However, when the exhaust fan is installed near the ceiling, the airflow from the nozzles hits the floor and rises between the mushroom blocks, picking up CO₂ along the way. This airflow pattern ensures that the gas mixes with the moving air and is efficiently removed through the exhaust. Conversely, if the exhaust is located near the floor, the airflow may not effectively capture the CO₂ around the growing clusters, resulting in inadequate ventilation.
Continuous Airflow: Maintaining continuous airflow is essential for creating a stable microclimate and preventing CO₂ buildup, excessive humidity, and poor mushroom formation. The exhaust fan should always be running unless the system is in 100% recirculation mode. This continuous ventilation ensures a consistent supply of fresh air and helps maintain optimal conditions for mushroom growth.
Strategic Fan Placement: The strategic placement of fans is crucial for ensuring even air distribution throughout the cultivation area. It is important to consider the size and layout of the growing space and position fans accordingly. Smaller areas may benefit from smaller, low-speed fans, while larger spaces may require larger, high-capacity fans. Additionally, the use of nozzles in air ducts can create controlled air movement, further enhancing even airflow distribution.
Air Exchange: Proper air exchange is vital for successful mushroom growth. Mushrooms release CO₂ and consume oxygen during their growth process. In an enclosed space without sufficient air exchange, oxygen depletion can occur, impeding growth and potentially suffocating the mycelium. Fans play a critical role in ensuring adequate air exchange by expelling CO₂ and supplying fresh oxygen to the growing environment.
Temperature Regulation: Fans contribute to temperature regulation by distributing air evenly throughout the growing area. Consistent air movement helps maintain a stable microclimate with uniform temperature and humidity levels, creating favourable conditions for mushroom growth and fruiting.
By understanding and implementing these airflow patterns and strategies, growers can optimize their mushroom cultivation setup, promoting healthy mushroom growth and maximizing their harvest.
