Growing mushrooms at home is an easy and rewarding endeavour. There are three primary ways to grow mushrooms at home: in a box, in a bucket, or on a log. The easiest and most popular species for home growing are button mushrooms, including portabella, shiitake, oyster, and chanterelle. Oyster mushrooms can be grown using the bucket method, while shiitake mushrooms grow well on logs. Before growing mushrooms, one must decide on the type of mushroom and whether to grow them indoors or outdoors. Mushrooms need a dark, cool place to grow, such as a basement or crawl space, and a damp environment with adequate airflow. They can be grown using a variety of substrates, including compost, straw, sawdust, or coffee grounds.

Choosing a mushroom type: Oyster, button, and shiitake are easy for beginners
Oyster, button, and shiitake mushrooms are great choices for beginners. Here's a detailed guide to help you choose the right type for your needs:
Oyster mushrooms are one of the most popular mushrooms globally and are very easy for beginners to cultivate at home. They are tolerant of various conditions and can be grown both indoors and outdoors. You can purchase ready-made growing kits or simply get mushroom spawn to inoculate your chosen growing medium. Oyster mushrooms require a specific combination of temperature, humidity, and nutrition to thrive. They grow quickly, and you can get up to three harvests from each indoor growing block. If you're growing them outdoors, one inoculated log can provide a crop for six to seven years. There are several varieties of oyster mushrooms, including pearl, blue, golden, pink, phoenix, and king oyster. However, king oysters are more difficult to cultivate as they prefer cooler temperatures.
Button mushrooms are another excellent option for beginners, as they can be grown indoors with minimal space and yield multiple harvests from a single setup. They are commercially significant and can be grown using a simplified kit without the complexity of substrate preparation and inoculation. The white button, cremini, and portobello varieties belong to the same species but differ in maturity and genetic strain. Button mushrooms are nutritious, containing significant quantities of B vitamins, potassium, selenium, and copper, with minimal caloric content.
Shiitake mushrooms can be a great next step for those who have already grown beginner-friendly strains like oyster mushrooms. They are found naturally growing on logs, so it is best to cultivate them on hardwood logs or dense wood-based substrates. Shiitake mushrooms require very few resources and can grow in various conditions, but they are not as versatile as oyster mushrooms. They are wood-decaying mushrooms, so extra precautions must be taken to prevent contamination and minimize the presence of other organisms in the substrate and growing environment. Shiitake mushroom growing kits are a popular option for beginners, as they often include all the necessary accessories and materials.
In summary, oyster mushrooms are a quick and adaptable option, button mushrooms are space-efficient and nutritious, and shiitake mushrooms are a more challenging but rewarding option for those looking to level up their mushroom-growing skills.

Growing location: Mushrooms can be grown indoors or outdoors
Mushrooms can be grown indoors or outdoors. They thrive in cool, humid, and dark environments.
If you're growing mushrooms outdoors, you need to consider your local climate. Mushrooms grow well in cool, humid conditions, but they can also be grown in more arid climates with frequent watering. Growing mushrooms outdoors can take a long time, ranging from six months to two years. Once established, healthy mushroom colonies can continue to grow for years.
There are several methods for growing mushrooms outdoors. One popular technique is to mix mushroom spawn with compost and let nature take its course. Another method is the log technique, which involves growing mushrooms on hardwood logs. Oysters and shiitakes are particularly well-suited for this method. You can also cultivate mushrooms in raised garden beds or in damp straw in shady areas of your garden.
If you have pets, it's important to note that some mushrooms can be toxic to dogs, so consider covering your plants.
Growing mushrooms indoors offers more control over the environment and allows for year-round cultivation. Mushrooms prefer a dark, cool place, such as a basement, crawl space, dark drawer, or cabinet. You can purchase mushroom cultivation kits or create your own setup using containers like monotubs or bags.
Whether growing mushrooms indoors or outdoors, maintaining proper conditions is crucial. Mushrooms require adequate moisture, temperature control, and limited light. Providing the right substrate, such as compost, straw, sawdust, or even coffee grounds, is essential for successful growth.

Substrate selection: Materials like compost, straw, or sawdust
The choice of substrate is crucial in mushroom cultivation, as it significantly impacts the quality and quantity of mushroom yields. The substrate acts as a food source for the mushroom mycelium, providing essential nutrients, moisture, and energy for growth and fruiting. Therefore, selecting the appropriate substrate for your chosen mushroom species is of utmost importance.
Compost
Compost is a nutrient-rich substrate that is particularly favoured by button mushrooms. It offers a blend of organic matter that supports the healthy development of the mycelium. Compost can be created by converting spent mushroom substrates into compost, providing an eco-friendly and sustainable approach to mushroom cultivation.
Straw
Straw is a traditional and affordable substrate that is commonly used for mushroom cultivation. It is particularly well-suited for growing oyster mushrooms, and other species such as agaricus, wine cap, shaggy mane, and enoki can also thrive on straw. Straw provides a carbon-rich base for mushroom growth and can be easily prepared using modest home utensils, making it a popular choice for growers. However, it may require additional preparation, especially for indoor cultivation, and it is not as nutritious as other substrates.
Sawdust
Sawdust is a practical and popular method for growing mushrooms, favoured by both enthusiasts and commercial growers. Sawdust mimics the natural environment where mushrooms flourish, such as on the forest floor among decomposing trees and branches. It is a cost-effective and widely available substrate that provides a great base for shiitake and lion's mane mushrooms. When using sawdust, it is important to ensure that it is made from untreated wood to avoid harmful chemicals. Additionally, supplements like wheat bran or rice bran can be added to enrich the substrate and enhance mushroom growth.

Spawn or spores: Purchase from a supplier or use spores
Spawn is the living fungal culture, called mycelium, grown onto a substrate. It is the genetic material used to grow mushrooms, much like seeds are used by gardeners and farmers. It is grown from selected genetics and cloned for consistent production of a particular cultivar of mushroom.
You can purchase spawn from a supplier, such as North Spore, which offers grain spawn, sawdust spawn, and plug spawn. Plug spawn is the type of spawn sold in small bags at garden centres, co-ops, and farmers' markets. They are locally produced wooden dowels that have been grown with mushroom mycelium. To use plug spawn, you need access to freshly cut hardwood logs. Drilling holes in the log, hammering in the spawn plugs, and sealing the holes with melted wax are the next steps.
Another option is to purchase spores from one of the many companies that produce them. Pick a reputable company with short shipping times to ensure the spores are fresh. You can create a liquid culture by mixing 1,500 ml of water, 1 tablespoon of raw honey, and 1 teaspoon of malt, then sterilizing the mixture with a pressure cooker. After that, you can put spores or a small piece of mushroom into the liquid. Wait a couple of weeks for the mycelium to grow inside the liquid, then put it into a syringe with a needle and inject it into your substrate. Alternatively, you can use a liquid culture kit, which usually costs about $20.
Growing from spores can be challenging, and some equipment is required. It is possible to mix spores with water and spray them onto a suitable substrate, but this method is less effective and can be expensive due to contamination issues.

Environmental controls: Maintain humidity, temperature, and airflow
Mushrooms require specific environmental conditions to grow, and it is important to maintain humidity, temperature, and airflow to replicate their natural habitat.
Humidity is a key factor in mushroom growth. Mushrooms require high humidity, and this can be achieved by routinely spraying the substrate with water. However, it is important to ensure that there is no standing water, as this can lead to contamination and affect the growth of mushrooms.
Temperature control is also crucial. Mushrooms thrive in cool environments, typically between 55-75°F (12-23°C). During the initial stages of growth, a higher temperature of around 70°F (21°C) is recommended. Once the mushrooms start to develop, the temperature can be lowered to 55-60°F (12-15°C).
Airflow is another important aspect of mushroom cultivation. Mushrooms require fresh air with a carbon dioxide content of 0.08% or lower. This can be achieved by ensuring proper ventilation in the growing area.
The specific requirements for each species may vary, and it is important to provide the optimal conditions for your chosen variety of mushrooms. Growing mushrooms outdoors takes into account the local climate, and they generally prefer cool, humid conditions. However, it is possible to grow them in arid climates with more frequent watering.
