Storage Temperature: Optimal temperature range for refrigerating mycelium to maintain viability and growth potential
The optimal temperature range for refrigerating mycelium is crucial for maintaining its viability and growth potential. Mycelium, the vegetative part of a fungus, is sensitive to temperature fluctuations, and improper storage can lead to reduced growth rates or even death. The ideal temperature range for most mycelium species is between 35°F (1.6°C) and 40°F (4.4°C). This range mimics the natural environment of many fungi, which often thrive in cool, damp conditions.
When storing mycelium in the refrigerator, it's essential to avoid temperature extremes. Temperatures below 32°F (0°C) can cause the mycelium to freeze, leading to cell damage and reduced viability. On the other hand, temperatures above 45°F (7.2°C) can promote excessive growth, which may deplete the mycelium's energy reserves and lead to a decrease in overall health.
To ensure optimal storage conditions, it's recommended to place the mycelium in a sealed container or plastic bag to maintain humidity levels. The container should be labeled with the date and species of mycelium to keep track of storage duration and to prevent cross-contamination. It's also important to check the mycelium regularly for signs of growth or spoilage, as this can indicate that the storage conditions need to be adjusted.
In addition to temperature, other factors such as light exposure and air circulation can also impact the viability of stored mycelium. Mycelium should be stored in a dark place, as exposure to light can inhibit growth. Proper air circulation is also crucial, as stagnant air can lead to the buildup of ethylene gas, which can promote spoilage.
By following these guidelines, you can ensure that your mycelium remains healthy and viable during storage, ready for use in your next cultivation project.

Humidity Control: Maintaining proper humidity levels in the fridge to prevent drying out or mold growth on mycelium
Maintaining proper humidity levels in the fridge is crucial when storing mycelium to prevent it from drying out or developing mold. The ideal humidity range for mycelium storage is between 80% and 90%. If the humidity is too low, the mycelium can dry out, losing its viability. Conversely, if the humidity is too high, it can lead to mold growth, which can contaminate the mycelium and render it unusable.
To control humidity levels, you can use a few different methods. One effective approach is to place a humidifier inside the fridge. This will help maintain a consistent humidity level. Alternatively, you can place a container of water inside the fridge, which will slowly evaporate and increase the humidity. It's important to monitor the humidity levels regularly using a hygrometer to ensure they remain within the desired range.
Another method to prevent drying out is to store the mycelium in an airtight container. This will help retain moisture and prevent the mycelium from being exposed to dry air. Additionally, you can wrap the mycelium in a damp paper towel or cloth before placing it in the container. This will provide an extra layer of moisture protection.
It's also important to note that the temperature of the fridge can affect humidity levels. A colder fridge will have lower humidity levels, so it's essential to store the mycelium in a part of the fridge that is not too cold. Ideally, the temperature should be between 35°F and 45°F (2°C and 7°C).
In summary, maintaining proper humidity levels in the fridge is essential for storing mycelium. By using a humidifier, a container of water, or an airtight container with a damp paper towel, you can create an environment that will keep the mycelium healthy and viable. Regular monitoring of humidity levels and ensuring the fridge temperature is within the optimal range will also help in maintaining the quality of the mycelium.

Container Selection: Choosing suitable containers for storing mycelium in the fridge, ensuring minimal contamination risk
Selecting the right container for storing mycelium in the fridge is crucial to prevent contamination and ensure the mycelium remains healthy. The ideal container should be airtight to prevent the entry of contaminants and the escape of moisture. Glass jars with tight-fitting lids are a popular choice among mycologists. These jars can be easily sterilized and reused, making them a cost-effective option.
When choosing a container, it's important to consider the size. The container should be large enough to accommodate the mycelium without overcrowding it. Overcrowding can lead to increased competition for nutrients and space, which can stress the mycelium and make it more susceptible to contamination. On the other hand, a container that is too large can lead to excessive moisture buildup, which can also increase the risk of contamination.
Another factor to consider is the material of the container. While glass is a good option, plastic containers can also be used. However, it's important to choose a food-grade plastic that is free from BPA and other harmful chemicals. Metal containers should be avoided as they can react with the mycelium and cause it to degrade.
Before storing the mycelium in the fridge, it's important to clean and sterilize the container. This can be done by washing the container with soap and water, then soaking it in a solution of bleach and water for at least 10 minutes. After sterilizing the container, it should be rinsed thoroughly with clean water and allowed to dry completely before use.
In addition to choosing the right container, it's also important to store the mycelium properly in the fridge. The mycelium should be placed in the crisper drawer, which is designed to maintain a high level of humidity. This will help to prevent the mycelium from drying out and becoming stressed. It's also important to avoid storing the mycelium near strong-smelling foods, as it can absorb odors and flavors from its surroundings.
By following these guidelines for container selection and storage, you can help to ensure that your mycelium remains healthy and free from contamination. This will not only improve the quality of your mycelium but also help to prevent the spread of harmful pathogens.
