Mushrooms are a unique life form that is distinct from plants and vegetables. They are a type of fungus that grows from spores, which are equivalent to seeds. While many mushrooms grow in the wild, they can also be cultivated through farming or at home. Mushroom farming often involves growing mushrooms indoors on shelves or in warehouses, using sterilized sawdust and wood chips. At home, mushrooms can be grown in an indoor compost bin with store-bought or homemade compost. Cultivating mushrooms offers the advantage of knowing whether they are safe to consume, as some wild mushrooms can be toxic to people and pets.

What You'll Learn
Mushrooms are fungi, not vegetables
Mushrooms are a type of fungus, not a vegetable. While they are often grouped with vegetables in terms of nutrition, they are not plants and do not come from plants. Instead, they are their own distinct category of life form.
Mushrooms have unique requirements for growth. They do not require sunlight and can be grown indoors, making them popular with urban farmers. They can be grown in warehouses, former industrial spaces, and even basements. The most common method for growing mushrooms is inside large plastic bags filled with sterilized sawdust and wood chips. This method replicates natural conditions, but it leaves behind a lot of plastic waste.
Another method for growing mushrooms is log growing, which has been used for hundreds, if not thousands, of years. Mushrooms can also be grown at home in an indoor compost bin. They grow from spores, which are too tiny to be seen with the naked eye. In the wild, mushrooms grow on soil and other substrates like wood, but no soil is necessary for cultivation. Instead, they can grow on materials like sawdust, grain, straw, or wood chips.
The process of growing mushrooms begins with spores, which are inoculated onto sterile cereal grains in a laboratory setting. These grains become "spawn," which can then be sown like seeds. At the farm, the grower prepares a growing medium called a "substrate," which can be synthetic compost or manure-based compost. The pasteurized substrate is placed in stacked wooden trays or beds, and the spawn is mixed in. From this point, it takes about three weeks to produce the first mushrooms for harvest. Mushrooms mature at different times, so they are hand-picked continuously for two to three weeks.

Mushrooms grow from spores, not seeds
Mushrooms are fungi and require different conditions to grow than plants. They grow from microscopic spores, not seeds. These spores are so tiny that they cannot be seen with the naked eye. In the wild, mushrooms grow on soil and other substrates like wood, but no soil is necessary for growing them at home. Instead, they can grow on materials like sawdust, grain, straw, or wood chips for nourishment.
A blend of the spores and these nutrient sources is called spawn. Mushroom spawn acts like a starter for making sourdough bread. The spawn is then used to inoculate a specific type of substrate, depending on the type of mushroom being grown. Like plants, different mushrooms require different growing conditions. However, unlike most plants, mushrooms have no chlorophyll and derive all their nutrients from the organic matter in their growing medium.
The substrate is the organic material in which mushrooms grow. The most commonly used spawn substrate is barley. To grow mushrooms without spores, one must first sterilize the barley and place it in a mason jar with water overnight. Then, cut the agar from the petri dish and place the cuttings in the jar. Each piece of agar mycelium should be one square inch. Place the jars in a dark environment and let the mycelium grow.
After the sterilization process, spawn production can begin. The mycelium is used to grow mushrooms without spores. It is added to a spawn substrate to increase the size of the mycelium. The substrate receipts should be added in a ratio of 5% barley to 95% straw. The straw should be chopped into 5-inch pieces and soaked in water. After acquiring the right substrate mixture, the bulk substrate must be pasteurized. Then, the barley spawn can be added to the bag. When the mycelium takes over the bag, holes must be punctured where small mushrooms are starting to develop. The mushrooms will grow out of these holes.

Mushrooms require specific substrates
Mushrooms are fungi, not plants, and require different conditions to grow. The type of mushroom determines the substrate used to grow it. Mushrooms can be grown on various substrates, including soil, wood, cardboard, corn cobs, and toilet paper rolls. However, each mushroom has specific needs, and providing the right mix of nutrients is crucial.
The substrate must provide the mushrooms with essential nutrients, including sugar, starch, lignin, fats, protein, and nitrogen. For example, white button mushrooms require composted manure, shiitake mushrooms thrive on wood or hardwood sawdust, and oyster mushrooms grow well on straw.
The most common method for growing mushrooms commercially is inside large plastic bags filled with sterilized sawdust and wood chips. These bags replicate natural conditions and help retain moisture. However, this method produces a lot of plastic waste and requires significant energy for sterilization and climate maintenance.
When growing mushrooms at home, the substrate can vary depending on the type of mushroom and the resources available. For example, one source suggests using trays filled with mushroom compost material and spawn, which are then covered with potting soil. The temperature is carefully controlled to create an optimal environment for mushroom growth.
Overall, mushrooms require specific substrates that provide the necessary nutrients and environmental conditions for their growth. The choice of substrate depends on the type of mushroom and the desired growth method, whether it is commercial or home cultivation.

Mushrooms can be grown indoors
Mushrooms are fungi and require different conditions to grow than plants. They can be grown indoors, and this has become popular with urban farmers. Mushrooms can be grown in warehouses, former industrial spaces, and even basements. The most common method for growing mushrooms is inside large plastic bags filled with sterilized sawdust and wood chips. This method replicates natural conditions, but it leaves behind a lot of plastic waste.
To grow mushrooms, fill trays with mushroom compost material and sprinkle spawn on top. Use a heating pad to raise the soil temperature to around 70 degrees for about three weeks or until you see the mycelium (white, thread-like growths). At this point, drop the temperature to between 55 and 60 degrees. Cover the spawn with an inch or so of potting soil. Harvest the mushrooms when they are fully grown. In about three weeks, small mushrooms should appear. When the mushroom caps separate fully from their stems, they are ready to harvest.
Mushrooms are a healthy addition to any diet as they are low in calories and fat, high in fibre, and contain high amounts of potassium and selenium. They are also versatile, fat-free, and filled with vitamins, antioxidants, and other nutrients.

Mushrooms are fast-growing
Mushrooms are fungi and require different conditions to grow than plants. They are not photosynthetic and must obtain their food from pre-existing material. Mushrooms grow from spores, which are so tiny that they cannot be seen with the naked eye. In the wild, mushrooms grow on soil and other substrates like wood, but no soil is necessary for growing them at home. Instead, they can grow on materials like sawdust, grain, straw, or wood chips for nourishment. A blend of the spores and these nutrient sources is called spawn. Mushroom spawn acts like a starter for making sourdough bread.
The substrate, or growing medium, for mushroom production is key. Synthetic compost consisting of wheat or rye straw, hay, crushed corn cobs, cottonseed meal, cocoa shells, and gypsum can be used. Alternatively, manure-based compost made from stable bedding from horse stables or poultry litter is also an option. The substrate must provide the right mix of nutrients, including sugar, starch, lignin, fats, protein, and nitrogen.
The process of growing mushrooms begins in a laboratory. The spores are inoculated onto sterile cereal grains and incubated until they develop into spawn. This spawn is then sown like seeds. At the farm, the grower prepares the substrate, which is usually placed in wooden trays or beds. The spawn is mixed in, and a top layer is applied. The temperature and humidity are carefully controlled, and mushrooms are harvested by hand.
