Growing gourmet mushrooms involves creating the ideal environment for the mushrooms to thrive, selecting the right growing medium, maintaining the perfect temperature and humidity levels, and following specific instructions carefully. With the right techniques and a patient mindset, anyone can master the art of mushroom cultivation and achieve a successful harvest.
1. Media Preperation
To begin with, the first step in cultivating a successful crop involves the selection of an appropriate growing medium. Once the growing medium has been selected, it is important to add water to it, ensuring a hydration level of approximately 60%. This step is crucial, as it ensures the growing medium has enough moisture to support the growth of healthy plants.
Following the hydration step, the growing medium must be sterilized and pasteurized to eliminate any harmful microorganisms that may inhibit plant growth or cause disease. Sterilization and pasteurization involve subjecting the growing medium to high temperatures and/or chemicals to kill off any unwanted microorganisms while preserving the beneficial ones.
After sterilization and pasteurization, the growing medium is ready for inoculation.
2. Inoculation
The art of mushroom cultivation involves the process of inoculation, which is the introduction of spawn or mycelium into the treated substrate. Unlike traditional plant cultivation, mushroom producers use the term “spawn” instead of “seed” due to the unique lifecycle of mushrooms. Spawn refers to a substance that has mycelium growing in and around it. Once the spawn is placed into the treated substrate, the mycelium will propagate and spread throughout the substrate.
The process of inoculation varies depending on the substrate being used. For substrates such as logs, straw, and wood chips, inoculation can be done outdoors without the need for protective gear. However, for substrates such as agar, grain, or enriched sawdust, it is imperative to conduct the inoculation in a sterile laboratory with proper ventilation.
By carefully following the inoculation process, growers can cultivate healthy and abundant mushroom crops. From logs to sawdust, the possibilities for mushroom cultivation are endless, and the techniques used to inoculate the substrate are critical for the success of the entire cultivation process.
3. Spawn Run
My favourite step is the spawn run. Simply relax and let the mycelium do its thing. It’s fascinating to see mycelium spread across the substrate. Many times, a very vigorous growing edge may be seen investigating the freshly prepared substrate with a textural array of mycelial filaments. Mycelium grows quickly during the spawn run. Mycelium continues to develop as quickly as possible, occupying as much of the fresh substrate as feasible. It will continue to grow indefinitely until it runs out of food or encounters competition. When all of the substrate has been populated, the spawn run is complete.
4. Full Colinisation
The mycelial growth pattern changes after full colonization. Rather than expanding, the mycelium focuses on absorbing available resources and preparing to build a fruiting body. The mycelium begins to devour the food that is now available to it in the substrate that it now lives in, on, and around. Mycelium discharges metabolites into the food source and absorbs sugars and carbon back into its body to generate new cells and increase the food supply. The substrate is ready to fruit mushrooms after complete inhabitation!
5. Pinning
The pinning process is a critical stage in the cultivation of mushrooms, and it is an exciting time for growers as it signals the beginning of the fruiting stage. During this stage, tiny pins or primordia begin to emerge from the substrate, a clear indication that the mushroom is starting to grow.
As the pins continue to grow, they will eventually develop into fully mature mushrooms. The process is a remarkable one to witness, as the tiny pins gradually grow into magnificent fungi, bursting with flavour and nutrition.
For growers, the pinning process is a time of careful observation and nurturing, as the pins are delicate and can be easily damaged. Maintaining the proper temperature, humidity, and air circulation is crucial during this stage, as it ensures that the pins will develop into healthy and robust mushrooms.
As the mushrooms continue to grow, they will start to take on their unique shapes, sizes, and colours. From the delicate and intricate patterns of the oyster mushroom to the classic round cap of the button mushroom, each species has its unique beauty and charm.
The pinning process is a testament to the wonder and complexity of nature, and for growers, it is a rewarding experience that requires patience, skill, and dedication. By paying close attention to the nuances of the pinning process, growers can cultivate a bountiful harvest of healthy and delicious mushrooms that will delight the senses and nourish the body.
6. Fruiting
The fruiting stage of mushroom cultivation is a remarkable process that marks the culmination of the growing journey. It is a time of great excitement for growers, as the hard work and patience invested in the previous stages are rewarded with the emergence of beautiful and bountiful mushroom fruiting bodies.
During this stage, the tiny pins that emerged during the pinning stage will develop into mature fruiting bodies, each one unique in shape, size, and colour. It is a sight to behold, as clusters of mushrooms emerge from the substrate, creating a stunning display of natural beauty.
The fruiting stage is a time of careful monitoring and management, as growers must maintain the ideal environmental conditions to ensure that the mushrooms grow to their full potential. Temperature, humidity, and air circulation must be carefully controlled, and any changes must be made with great care to avoid damaging the delicate fruiting bodies.
As the mushrooms continue to grow and mature, they will release their signature aroma, filling the air with a rich, earthy scent. The fruiting stage is a time of sensory delight, as the mushrooms tantalize the taste buds and awaken the senses.
For growers, the fruiting stage is a time of great pride and satisfaction, as they witness the fruits of their labour coming to life. From the plump, succulent caps of the portobello mushroom to the delicate, feathery fronds of the shiitake, each mushroom species has its unique charm and flavour.
In the end, the fruiting stage is a testament to the wonders of nature and the power of human ingenuity. With skill, care, and patience, growers can cultivate healthy and delicious mushrooms that nourish both the body and the soul.
7. Rest
Everything requires relaxation! Plants sleep, animals sleep, fish slumber, germs cool, and fungi are no exception. Fruiting mushrooms is a difficult task, and the fungus must rest and recover afterwards. The mushrooms continue to eat the food source and amass nutrients for another fruiting at this stage! I hope this guide to growing gourmet mushrooms is helpful in your search for abundant mushroom harvests!
