What You'll Learn
Fanning frequency depends on humidity
The frequency of fanning mushroom cakes depends on several factors, including humidity, temperature, and the specific mushroom variety. While some growers recommend fanning multiple times a day, others suggest less frequent fanning with proper humidity control.
Fanning is essential to provide adequate air exchange and prevent the growth of contaminants that thrive in stagnant, humid environments. However, excessive fanning can lead to decreased humidity and dry cakes, negatively impacting mushroom growth. Therefore, it is crucial to maintain a balance between fanning and humidity control.
In general, mushroom cakes require high humidity levels, ideally between 95-100% relative humidity. The humidity level can be controlled by misting the cakes or using a humidifier. By maintaining high humidity, you can reduce the frequency of fanning while still providing the necessary air exchange.
Additionally, the temperature of the growing environment plays a role in determining the fanning frequency. In warmer conditions, evaporation occurs more rapidly, leading to decreased humidity. Therefore, more frequent fanning may be necessary to compensate for the faster evaporation rate.
Moreover, different mushroom varieties may have specific humidity and fanning requirements. Some mushrooms prefer higher humidity levels, while others can tolerate slightly lower humidity. It is essential to research the specific needs of the mushroom variety you are cultivating to determine the optimal fanning frequency.
In conclusion, the frequency of fanning mushroom cakes depends on various factors, with humidity being a critical component. By maintaining high humidity levels through misting or humidification, you can reduce the need for frequent fanning while still providing adequate air exchange. However, it is important to find a balance and avoid over-fanning, as it can lead to dry cakes and hinder mushroom growth.

Fanning and misting schedules
The frequency of fanning and misting your mushroom cakes depends on several factors, including the size of your setup, the humidity levels, and the growth stage of your mushrooms. Here are some detailed guidelines and tips to help you create an effective schedule:
Fanning Schedules
- It is generally recommended to fan your mushroom cakes at least once a day. Fanning helps provide fresh air and facilitates gas exchange, which is crucial for mushroom growth.
- Aim to fan multiple times a day, ideally between 3 to 5 times. Some growers fan up to 6 or 7 times a day. The more air exchange, the better, as long as humidity is maintained within an acceptable range.
- If you have a smaller setup, such as a shoebox-sized bin, you may only need to fan once a day. Larger setups may require more frequent fanning.
- You can fan by using the lid of your container. Simply remove the lid and gently fan the cakes for about 30 seconds a few times a day. This method is considered “proper” by some growers.
- Another method is to use a fan or a blow dryer set to the "cool" setting. Blow each cake individually and then the chamber as a whole for 2-5 minutes.
- In addition to manual fanning, you can also increase air exchange by drilling holes in the plastic lid of your container. This passive form of fanning will provide continuous air circulation.
- Some growers recommend leaving the lid off of your chamber for 10 minutes after each fanning session to further promote air exchange.
Misting Schedules
- Misting provides moisture to the mushroom cakes and helps maintain humidity. The frequency of misting depends on the humidity levels in your setup and the moisture needs of your mushrooms.
- Mist until the surface of the cakes looks like it is covered in dew. This technique will vary depending on the moisture levels in your cakes, so you'll need to develop a feel for it.
- Some growers recommend misting before fanning. Misting first helps replace the moisture that may be lost during fanning and ensures the cakes don't dry out too quickly.
- If your local humidity is regularly 40 or less, misting may be necessary more frequently to compensate for the drier conditions.
- Others suggest misting after fanning. This approach helps maintain humidity levels by replacing the moist air that was circulated out during fanning.
- If you are growing your mushrooms in a properly designed self-growing mushroom fruiting chamber (SGFC), fanning may not be necessary at all, and misting alone can provide adequate humidity.

Preventing over-fanning
Over-fanning can cause issues with mushroom growth, such as drying out the cakes too much and causing overgrown stems. To prevent over-fanning, it is important to maintain the right balance of humidity and air exchange. Here are some tips to avoid over-fanning:
Maintain Humidity
Keep the humidity levels high, especially if you are fanning multiple times a day. Misting the cakes with water can help maintain humidity. One user recommends misting the cakes directly until pins start to form, then misting the air above the cakes with the lid off and letting the mist settle before replacing the lid. Another user recommends misting until the surface looks dewy, while another suggests misting 3-4 times a day, depending on how dry or wet the environment is, to keep the cakes glistening with small beads of water. However, one user cautions that misting too much can waterlog the cakes.
Allow for Air Exchange
While humidity is important, adequate air exchange is also crucial to prevent stagnant air, which can lead to contamination. Drill holes in the plastic lid of your setup to allow for air exchange. One user recommends poking holes about an inch apart all over the lid. Another user suggests having an airstone and a small pump in a filter box running continuously to increase air exchange.
Fan at Regular Intervals
Fanning at regular intervals, rather than too frequently, can help prevent over-fanning. Most users recommend fanning at least once a day, with some recommending 2-3 times a day. One user suggests fanning at different times throughout the day, such as when you wake up, when you leave for classes or work, when you return, and before you go to bed. Another user recommends fanning for about 30 seconds using the lid a few times a day.
Monitor the Mushrooms
Pay attention to the appearance of your mushrooms to ensure you are not over-fanning. If you notice signs of over-fanning, such as dry cakes or overgrown stems, adjust your fanning frequency accordingly. One user recommends starting with one method, observing the mushrooms, and then researching their current state to make any necessary adjustments.
