Temperature Guidelines for Mushroom Growth Stages
Understanding the temperature requirements for each mushroom growth stage is essential for ensuring healthy and productive mushroom cultivation. Let’s delve into the temperature guidelines for the spawn run stage, pinning stage, and fruiting stage:
Spawn Run Stage
The spawn run stage is the initial phase of mushroom cultivation after inoculating the substrate with mushroom spawn. During this stage, mycelium growth occurs, and establishing the right temperature conditions is crucial for successful colonization. The ideal temperature range for the spawn run stage varies depending on the mushroom species being cultivated.
For button mushrooms and oyster mushrooms, temperatures between 55°F to 60°F (12°C to 16°C) are recommended. Shiitake mushrooms prefer slightly higher temperatures, between 75°F and 81°F (24°C to 27°C). Lion’s mane mushrooms also thrive in a temperature range of 65°F to 70°F (18°C to 21°C) during the spawn run stage.
If the temperature is too high or too low during the spawn run stage, it can negatively affect mycelial growth and lead to poor colonization. Suboptimal temperatures can result in slow growth, increased susceptibility to contamination, and overall lower yields.
Pinning Stage
The pinning stage is when the first signs of mushroom formation, known as pins, become visible. Controlled temperature settings are critical during this stage to promote the development of healthy and abundant fruiting bodies.
The optimum temperature range for the pinning stage varies depending on the mushroom species being cultivated. For button mushrooms and oyster mushrooms, maintaining temperatures between 55°F and 65°F (12°C to 18°C) is ideal. Shiitake mushrooms prefer slightly higher temperatures, between 59°F and 68°F (15°C to 20°C). Lion’s mane mushrooms, on the other hand, can tolerate temperatures in the range of 55°F to 65°F (12°C to 18°C).
Extreme temperature fluctuations or temperatures outside the recommended range can delay or inhibit fruiting body formation during the pinning stage. It’s important to provide stable and appropriate temperature conditions to ensure successful initiation of mushroom growth.
Fruiting Stage
The fruiting stage is when mushrooms reach maturity and are ready for harvest. To achieve the best yields and quality, maintaining the proper temperature range is crucial during this stage.
For button mushrooms, shiitake mushrooms, oyster mushrooms, and portobello mushrooms, a recommended temperature range of 55°F to 65°F (12°C to 18°C) promotes optimal fruiting body formation and growth. Lion’s mane mushrooms prefer slightly cooler temperatures, between 55°F and 65°F (12°C to 18°C), while reishi mushrooms thrive in temperatures between 70°F and 80°F (21°C to 27°C). Enoki mushrooms prefer cooler temperatures between 46°F and 55°F (8°C to 13°C) during the fruiting stage.
Deviation from the recommended temperature range during the fruiting stage can lead to stunted or malformed mushrooms, reduced yields, or complete failure to fruit. Maintaining consistent temperature conditions is crucial for a successful harvest.
