Understanding Mycelium

Mycelium is the vegetative part of the fungus or fungal-like bacterial colonies, consisting of a mass of branching, thread-like hyphae.

Definition of Mycelium

Mycelium is the primary structure of a fungal organism. Similar to how plants have roots, fungi consist of mycelium. These structures are thread-like, and they form a vast network under the soil surface. Though individual threads (known as hyphae) are microscopic, the mycelium network can span enormous areas.

The role of Mycelium in Fungi Growth

In the lifecycle of fungi, the mycelium plays a significant role by acting as the nutrient and water collection mechanism for the organism. It grows within the substrate, extracting necessary nutrients for fungi growth. Mycelium networks do more than just absorb nutrients; they also enhance the soil’s water-holding capacity and support other beneficial microbial populations.

Benefits of Healthy Mycelium

Healthy mycelium helps in producing robust, well-nourished fungi. It ensures optimal nutrient and moisture absorption, leading to faster and healthier growth. Mycelium is also crucial for fungus integrity since it reproduces by releasing spores, contributing to new fungi clusters. Moreover, in the environmental context, healthy mycelium can improve the soil’s health, quality, and fertility through its symbiotic relationships with plants and other organisms.

Setting up a Monotub

Monotub, a highly popular technique used for cultivating mushrooms indoors, emphasizes simplicity and efficiency.

Choosing a Suitable Monotub

When picking a monotub for mycelium growth, ensure it has sufficient volume to hold the mycelium and the substrate. Plastic storage boxes often work well as monotubs. They’re relatively cheap, widely accessible, and come in various sizes to cater to different yield expectations.

Necessary Equipments for Monotub Setup

The typical list of equipment required for setting up a monotub includes: the tub itself, a drill to create ventilation holes, a heater if necessary, a thermometer/humidity gauge, polyfill or micropore tape for filling the holes, substrate, and spray bottles for misting.

Step-by-Step Guide on Monotub Setup

Setting up a monotub involves several steps. First, you prepare your tub by drilling holes on its sides for ventilation. Fill these holes lightly with polyfill or cover them with micropore tape. Next, fill the tub with a layer of your chosen substrate. Be aware of the required substrate depth for the specific mushroom species you’re cultivating. Once you add the substrate, sterilize it properly before inoculation.

The Importance of Sterility in Growing Mycelium

Sterility is essential in mycelium cultivation to protect it from contaminants, which can jeopardize the entire cultivation cycle.

Ways to Sterilize the Monotub

Cleaning and sterilizing the monotub before adding the substrate is crucial. Fill your tub with a bleach solution, let it soak for a few hours, then rinse out the tub are good practices. To sterilize the substrate, baking, boiling, or pressure cooking can be implemented according to the substrate type.

Handling Sterilized Instruments and Materials

When handling sterile equipment and materials, ensure your hands or gloves are clean to avoid introducing contaminants. Dispose of any unused substrate or media in a sanitary manner, and always work in a clean area.

Common Contaminants and How to Avoid Them

Common contaminants include bacteria and molds. These can be avoided with stringent cleanliness practices, sterilizing equipment, and proper storage and handling of substances. Paying attention to the tub’s temperature and humidity can also reduce the likelihood of contamination.

Preparing the Mycelium Substrate

The growth substrate is like food for your mycelium, providing the nutrients it needs to grow and flourish.

Different Types of Substrates

Substrates vary depending on the fungal species. Commonly used substrates include straw, wood chips, grain, and compost mixtures. Some species have specific substrate preferences, so ensure compatibility before preparation.

How to Prepare the Substrate at Home

To prepare a substrate at home, you need to combine the preferred materials according to the recommended proportions and then thoroughly sterilize it, through baking, boiling, or autoclaving, to eliminate potential contaminants.

Correct Method to Add Substrate in Monotub

When adding substrate to a monotub, spread it evenly throughout the tub, making sure to maintain an appropriate depth. The exact depth varies with the type of mushroom but generally falls within the one to three inch range.

Inoculating the Monotub

Inoculation introduces mycelium into the substrate, marking the commencement of the cultivation process.

What is Inoculation in Fungi Cultivation

Inoculation refers to the introduction of mycelial culture, usually in the form of spores or liquid culture, into the sterilized substrate.

Inoculation Methods Suitable for Mycelium

There are various suitable methods for inoculating mycelium, including spore syringes, agar cultures, and grain spawn. Spore syringes and liquid cultures are generally easier for beginners, while grain spawn provides faster colonization times for advanced cultivators.

Tips for successful Inoculation

For successful inoculation, maintain a sterilized environment and use only high-quality mycelium cultures or spore syringes. Also, the substrate should be cooled down to room temperature to prevent heat shock.

Conditioning the Monotub for Mycelium Growth

Creating a conducive environment for mycelium growth is fundamental for prosperous harvests.

Monitoring and Maintaining Temperature

Mycelium grows best within a certain temperature range. Regularly monitor and maintain the temperature within the optimal range, usually between 20 to 28 degrees Celsius.

Controlling and Sustaining Humidity

Humidity is crucial for mycelium growth. Keeping your monotub humid, usually between 75%-85%, supports mycelium in absorbing water to build necessary cellular structures.

Light Requirements for Mycelium

Despite being different from plants, mushrooms do need exposure to light, albeit less intense. Indirect sunlight or fluorescent light is typically sufficient.

Monitoring and Taking Care of the Growing Mycelium

Ensuring that your mycelium is growing well requires regular monitoring and care.

Signs of Healthy Mycelium Growth

Healthy mycelium typically looks white and fluffy or stringy, and it should gradually spread throughout the substrate. Bad odor, change in color or stagnant growth indicate potential issues.

Troubleshooting Common Problems

common problems include contamination, low humidity, or inappropriate temperature. Treating contamination as soon as possible, adjusting the temperature, and keeping an eye on your humidity levels are effective ways to troubleshoot these issues.

Save a Contaminated Monotub

If detected early, contamination can be mitigated by removing the affected area of the substrate. However, if the contamination persists or has spread significantly, it might be wiser to start over to avoid spore spreading.

Harvesting Mycelium from Monotub

When the mycelium has fully colonized the substrate, it’s time to start thinking about the harvest.

When and How to Harvest Mycelium

Harvesting usually takes place when the fruiting bodies or mushrooms reach their maturity. The exact timing varies depending on the species. Harvest by gently pulling or twisting the mushrooms, taking care not to damage the mycelium network.

The Harvesting Tools Needed

Harvesting tools include clean, sharp scissors or a blade and a container to collect your harvest. All tools should be sterilized to prevent contamination.
