Mushrooms are a type of fungus that grows from a network of thread-like roots called mycelium. When growing mushrooms, the pinning stage is a crucial step in the process. Mushroom pins are the precursors to mature mushrooms and are formed when the mycelium clumps together, creating tiny bumps on the surface of the mycelium covering the mushroom substrate. These bumps develop into matchstick-like structures called primordia, which are considered an earlier stage of fruiting. The time it takes for pins to develop into mature mushrooms varies depending on the species and environmental conditions, but it generally ranges from a few days to a couple of weeks. Optimal conditions for pinning include factors such as temperature, humidity, airflow, and light.
| Characteristics | Values |
|---|---|
| Definition | The first stage of mushroom pinning looks like tiny bumps forming on the surface of the mycelium covering the mushroom substrate. |
| Visual Appearance | Mushroom pins are elongated and no longer ball-shaped. They also start to develop a cap, although this can be unnoticeable in some mushroom species. |
| Primordia | The absolute first stage at which hyphae start to change and form a different structure that does not look like mycelium. These are the little balls that form in the substrate before pins start developing. |
| Pinning Initiation | Pinning initiation depends on climate conditions and seasons of the year. In temperate and continental climates, most mushrooms fruit during the cool, rainy spring and autumn. In tropical and subtropical climates, mushrooms fruit during the rainy season. |
| Environmental Requirements | Mushrooms require light, fresh air, high humidity, and specific temperature ranges for pinning. |
| Stalled Pin Growth Causes | Suboptimal environmental conditions, lack of nutrients, and fluctuations in temperature and humidity can cause stalled pin growth. |
| Side Pins | Side pins are a common problem for those growing magic mushrooms. They are mushrooms that grow on the side of the substrate due to the formation of a tiny space between the substrate and its container, creating a perfect microclimate for mushroom growth. |

The pinning process begins when mycelium clumps together to form hyphal knots, causing bumps on the substrate's surface
The pinning process is an important phase in the mushroom life cycle. It occurs when mycelium, composed of hair-like cells called hyphae, clumps together to form hyphal knots. These hyphal knots are the first visible sign of a mushroom's development to the naked eye. The clumping of mycelium causes small bumps to form on the surface of the substrate, indicating the beginning of the pinning process.
During the pinning process, mushrooms undergo cell division to form all the cells necessary for the production of mature mushrooms. These hyphal knots develop into primordia, also known as baby mushrooms or mushroom pins. The primordia often resemble pinheads, giving rise to the term "pins." While some mushrooms may start pinning as soon as they colonize the substrate, others may require more specific conditions, such as lower temperatures, high humidity, fresh air exchange, and controlled CO2 levels.
To initiate pinning, growers can simulate autumn-like conditions by lowering temperatures and increasing humidity. Light also plays a crucial role during the pinning stage, triggering the transition from vegetative growth to reproductive growth. However, excessive direct light should be avoided as it can increase substrate temperature and reduce humidity, potentially hindering pin development. Therefore, a balance between light exposure, temperature, and humidity is essential.
The pinning process typically takes about 7 to 14 days to complete. However, the time for primordia to develop into mature mushrooms can vary depending on the mushroom species and environmental conditions. Growers should be patient and provide optimal conditions to ensure successful pinning and subsequent mushroom growth.
Additionally, it is important to monitor environmental parameters such as temperature, humidity, air exchange, and substrate health. Stalled pin growth can occur due to suboptimal conditions or a lack of nutrients. By understanding the specific needs of the mushroom species and adjusting the environment accordingly, growers can optimize pinning success and overall yield.

Primordia are formed during the pinning process and develop into pins, which are longer and have caps
Mushroom pinning is a crucial stage in the mushroom cultivation process, marking the transition from vegetative growth to the formation of fruiting bodies. Primordia are formed during the pinning process and develop into pins, which are longer and have caps.
The pinning process begins when the mycelium clumps together to form hyphal knots, causing small bumps to form on the surface of the mycelium covering the mushroom substrate. These bumps or hyphal knots continue to grow and develop into tiny primordia, which are the first signs of mushroom pinning. Primordia are the very first stage of the formation of fungal fruiting bodies. They are small, dense, white masses that form around the openings of mushroom blocks. These masses then transform into oyster mushroom rudiments, or primordia.
Primordia and pins are almost the same, and some people use the terms interchangeably. However, they refer to slightly different stages of the early fruiting process. Pins are at a later stage and are usually more elongated and no longer ball-shaped. They also start to develop a cap, although this can be unnoticeable in some mushroom species. The time it takes for primordia to develop into fully grown fruiting bodies varies depending on the mushroom species and environmental conditions. Generally, it can take anywhere from a few days to a couple of weeks for the pins to develop into mature mushrooms.
To initiate pinning, it is important to create the optimal environmental conditions. For example, oyster mushrooms prefer higher humidity and more frequent air exchanges, while shiitake mushrooms require a drop in temperature. Maintaining high humidity during the pinning process can be achieved by misting the growing kit or blocks two to three times per day. It is also important to monitor and adjust key environmental parameters such as CO2 levels, lighting, humidity, and temperature during the fruiting stage.
By understanding the pinning process and optimizing the growing conditions, mushroom growers can influence the number of primordia formed and the number of pins that develop into mature mushrooms. This, in turn, can impact the size, quality, and yield of their crop.

Optimal pinning conditions vary by mushroom species, with some requiring lower temperatures and higher humidity
To ensure optimal pinning and growing conditions, it is recommended to use a mushroom fruiting chamber. Monotubs, shotgun fruiting chambers, and Martha grow tents are all low-cost DIY options for beginner mushroom growers. A well-designed fruiting chamber should include proper air circulation, temperature control, humidity control, and lighting. For example, oyster mushrooms require regular misting and increased air circulation, while shiitake mushrooms require the removal of the grow bag and misting of the colonized substrate.
The pinning stage impacts the final mushroom yields, and growers must simulate the mushroom's ideal natural conditions. The greater the number of mushroom pins, the higher the yield. However, mushrooms with fewer pins and less competition for nutrients can grow larger.
The pinning process begins with tiny bumps forming on the surface of the mycelium covering the mushroom substrate. These bumps, or hyphal knots, develop into matchstick-like primordia or mushroom pins. During pinning, mushrooms use cell division to form all the cells necessary for maturation. Once pinning is complete, they no longer rely on cell division for growth but instead flood existing cells with water and nutrients, allowing them to expand rapidly.
To initiate pinning, it is crucial to provide light and reduce CO2 levels. Additionally, simulating autumn-like conditions, including lower temperatures and higher humidity, signals to the mycelium that it is an appropriate environment for fruiting.

Pinning is initiated by introducing fresh air and specific environmental triggers, such as light and temperature changes
Pinning is a crucial stage in the mushroom cultivation process, marking the transition from vegetative growth to the formation of fruiting bodies. Mycelium pinning, also known as primordia formation, is when the mycelium differentiates and forms tiny, initial structures called pins. These pins eventually develop into mature fruiting bodies or mushrooms.
To initiate pinning, fresh air and specific environmental triggers, such as light and temperature changes, are introduced. Different mushroom species have varying pinning requirements and preferences. For instance, oyster mushrooms prefer higher humidity and more frequent air exchanges, achieved through regular misting and increased air circulation. On the other hand, shiitake mushrooms require a sudden drop in temperature, known as a "cold shock," to stimulate pinning. This temperature change is a critical factor, with most species requiring a decrease in temperature to initiate the process.
Light also plays a significant role during the pinning stage. While mycelium does not require light during the colonization phase, light becomes an important environmental trigger during pinning. It signals the mycelium to transition from vegetative growth to reproductive growth. However, excessive direct light should be avoided as it can increase substrate temperature and reduce humidity, potentially hindering pin development. Therefore, balancing light exposure with proper temperature and humidity management is crucial.
Additionally, maintaining optimal CO2 levels is essential for successful pinning. High CO2 levels can inhibit pin formation, while insufficient air exchange can result in poor pin development. Aiming for 3-5 air exchanges per hour helps maintain the ideal CO2 concentration for pinning. Proper humidity levels are also critical, as low humidity can cause pins to dry out, and high humidity can lead to mould and bacterial contamination.
Understanding and managing these environmental factors are key to optimising the pinning process and ensuring a successful mushroom cultivation experience.

Side Pins in Magic Mushrooms
To prevent side pins, it is important to maintain optimal environmental conditions and ensure uniform moisture in the substrate. Here are some strategies to achieve this:
- Misting the substrate surface when it is not moist enough can help prevent drying out and the formation of side crevices. Be generous with the mist, but avoid water pooling.
- Using a liner between the substrate and the tub can help maintain even humidity levels and reduce the formation of microclimates that lead to side pins. A simple black garbage bag or a clear bag can be used as a liner, covering all ends except the top.
- Adjusting air exchange rates can help manage humidity and temperature. Closing air holes by half or completely and flipping the lid of the tub can also create the desired microclimate balance.
- Keeping the substrate in complete darkness during the colonisation phase can help prevent premature pinning and reduce contamination risks.
- For shiitake mushrooms, spraying the blocks directly two to three times a day during the initial fruiting phase is recommended until the mushroom pins are thumbnail-sized.
By implementing these strategies, growers can reduce the occurrence of side pins and guide the mushrooms to fruit predominantly on the surface of the substrate, resulting in more accessible and aesthetically pleasing top-fruiting mushrooms.
