One common issue faced by mushroom growers is side pinning, which can lead to an uneven and less productive yield. In this blog post, we'll discuss the causes of side pinning and share some effective strategies to prevent it.

Key Takeaways:

Side pinning: Mushrooms fruiting along container sides, causing uneven yield and difficult harvesting.

Causes: Low humidity and dry substrate surface, poor air exchange, light exposure on container walls.

Solutions:

• When initiating fruiting, heavily mist substrate surface and humidity dome to create ideal fruiting conditions from the start.

• If there is signs of heavy overlay on top of the substrate, consider the fork tek.

• Aim for consistent internal mist like that on a cold soda can on a warm day.

• Ensure proper air exchange through clean, unobstructed fresh air exchange patch and frequent opening (1-2 times per day) of the container to mist as needed.

• Maintain consistent moisture levels; avoid oversaturating substrate.

• If side pins occur, harvest as possible and adjust fruiting conditions for follow-on flushes.

• RyzaPods minimize side pinning with blackout label, injection port, and FAE filter patch.

Understanding Side Pinning

Side pinning occurs when mushrooms begin to fruit along the sides of the substrate container instead of on the substrate surface. This happens when the conditions along the sides of the container are more favorable for pinning than those on the top. Factors that contribute to side pinning include low humidity, poor air exchange, and the presence of light near the substrate.

Preventing Side Pinning with RyzaPods: Our RyzaPods are designed with features that help minimize the risk of side pinning. The included blackout label on the substrate jar prevents light from penetrating the sides, discouraging pinning in those areas. Additionally, the humidity filter patch allow for controlled air exchange, maintaining optimal conditions within the pod. Daily or more frequent opening of the dome also helps exchange air. But the primary factor is ensuring the top of the substrate is well-wetted when initiating fruiting, followed by a steady misting that prevents puddles from forming.

Proper Fruiting Conditions

To further prevent side pinning, it's crucial to create ideal fruiting conditions on the top of the substrate. This can be achieved by heavily misting the surface of the substrate and the inside of the humidity dome once the pod has fully colonized to kick things off. If there is significant overgrowth or overlay on the top of the substrate, use a sterile tool to lightly break up the surface (called the fork technique). Following this, maintain high humidity levels and misted top surface to encourage the mushrooms to fruit upwards, away from the sides of the container. Indirect lighting which gets to the top surface also can help signal to mycelium where best to pin.

Adequate Air Exchange

Ensuring proper air exchange is another key factor in preventing side pinning. The fresh air exchange patch on the humidity dome allows for sufficient air circulation, which helps regulate humidity and prevents stagnant air pockets that can trigger side pinning. Be sure to keep the patch clean and unobstructed for optimal performance.

Maintaining Proper Moisture Levels

Consistent moisture is essential for healthy mushroom growth and can help prevent side pinning. Regularly mist the inside of the humidity dome to maintain high humidity levels. However, be cautious not to oversaturate the substrate, as excessive moisture can lead to contamination and other issues. The internal surface and substrate should be consistently moist, like a cold soda can on a warm sunny day.

Patience and Observation

Mushroom fruiting requires some patience and attentive observation. Monitor your RyzaPods closely during the fruiting stage, and adjust the humidity and air exchange as needed. If you notice any signs of side pinning, gently redirect the growth towards the surface by creating more favorable conditions on top of the substrate.

Conclusion

Preventing side pinning is essential for achieving a robust and even mushroom harvest. While side pinning can be a nuisance, the mushrooms produced are just as good as the more aesthetically pleasing “canopies” that growers covet.

By understanding the causes of side pinning and implementing the right techniques, you can maximize your yields and enjoy a satisfying growing experience. Our RyzaPods are designed to make mushroom cultivation accessible and straightforward, with features that help minimize side pinning. Remember to create optimal fruiting conditions, maintain proper moisture levels, indirect light exposure and ensure adequate air exchange. With patience and care, you'll soon be enjoying a bountiful crop of beautiful mushrooms. Happy growing!
