Mushrooms are a fascinating kingdom of life all their own—not animals, not plants, but fungi. They are tasty, nutritious, and can even be good for our brains. Growing your own mushrooms can be easy, and there are several ways to do it: in a box, in a bucket, or on a log. The easiest mushrooms to grow are button mushrooms, including portabella, shiitake, oyster, and chanterelle. You can buy mushroom growing kits, which will provide you with a substrate and spores, as well as instructions. If you want to assemble the materials yourself, you will need a plastic tub or baking pan, mushroom spawn, a growing substrate like compost, straw, sawdust, or coffee grounds, a damp towel, and a spray bottle.

What You'll Learn
Choose a mushroom type and substrate
The first step to growing mushrooms is deciding which type of mushroom you want to grow. Oyster, button, and shiitake mushrooms are the easiest for beginners. Chanterelle mushrooms are also popular, but they may require a bit more care.
Once you've chosen your mushroom type, it's time to select the right substrate. The substrate is the material that the mushrooms will grow on, and different mushrooms thrive on different substrates. Some common substrates include compost, straw, sawdust, coffee grounds, and wood chips. You can also get more creative and use substrates like clay-loam soil or a mixture of soil and sawdust.
If you're a beginner, it's recommended to start with a simple substrate like compost or sawdust. These substrates are widely available and relatively easy to work with. Sawdust, in particular, is a good option because it can be purchased already inoculated with mushroom spores, making the process simpler.
Another important consideration is whether to pasteurize your substrate. Pasteurization can help kill any contaminants that may be present, especially in substrates like straw or sawdust. This step is not mandatory but can help improve the success rate of your mushroom growth.
Additionally, you can choose to purchase a mushroom growing kit, which will provide you with a substrate and spores, as well as instructions on what to do. This is a great option for beginners to get familiar with the process before experimenting with different substrates and mushroom types.
Overall, choosing the right mushroom type and substrate is a crucial first step in your mushroom-growing journey. With the right combination of species and substrate, you'll be well on your way to a successful and rewarding experience.

Prepare the substrate
Preparing the substrate is a crucial step in cultivating mushrooms. The substrate is the material on which the mushrooms grow, and different types of mushrooms thrive on different substrates. Common substrates include compost, straw, sawdust, coffee grounds, wood chips, and clay-loam soil. You can also purchase pre-made substrates from companies that specialise in mushroom cultivation.
When preparing your substrate, it is important to ensure it is clean and free of contaminants. One way to do this is by pasteurising the substrate, especially if you are using straw or sawdust. This process kills off any potential contaminants that could hinder the growth of your mushrooms. Other treatments for the substrate include sterilisation, lime bath, peroxide bath, and cold fermentation.
After treating the substrate, the next step is to introduce the mushroom spores or spawn to the substrate. The spawn is the living fungal culture, also known as mycelium, that will grow into the mushrooms. You can purchase spawn from a reputable mushroom cultivation supplier. When mixing the spawn into the substrate, it is important to maintain the recommended temperature for your specific mushroom variety. For example, the substrate temperature for Pleurotus ostreatus should be maintained at 75° F during the spawn run.
Once the spawn has been introduced to the substrate, you will need to wait for the mycelium to fully colonise the substrate. This process involves the mycelium permeating the substrate, absorbing the nutrients it needs to develop. The time it takes for colonisation to occur can vary depending on the mushroom species and environmental conditions. During this stage, it is crucial to maintain the recommended environmental conditions, including temperature, light, humidity, and airflow, to promote the healthy growth of your mushrooms.

Inoculate the substrate
Inoculation involves introducing the mushroom spawn or culture into the substrate, providing the mycelium with a food source to grow and colonize. This step requires a sterile environment to prevent contamination by other microorganisms. Here's a detailed guide on how to inoculate the substrate:
Prepare the Spawn and Substrate
Obtain high-quality mushroom spawn or culture. Commonly used spawn types include grain spawn (e.g., rye, wheat), sawdust spawn, or liquid culture.

Control the environment
Mushrooms require specific environmental conditions to grow. They are not photosynthetic, so they must obtain their food from the substrate they grow in. This substrate must be rich in organic material and provide the right mix of nutrients, including sugar, starch, lignin, fats, protein, and nitrogen. Mushrooms grow best in cool, humid, and dark conditions.
When growing mushrooms, it is essential to maintain a clean environment to prevent contamination. The growing medium should be pasteurized or sterilized to kill any potential contaminants. Maintaining high moisture levels is crucial, but standing water should be avoided. Routine spraying of the substrate with water can help achieve the desired humidity levels.
Temperature control is also vital for mushroom growth. Different mushroom species have specific temperature requirements, and these must be maintained during the colonization and fruiting phases. For example, the colonization temperature for Pleurotus ostreatus is recommended at 75°F (23°C/73°F). After colonization, when the small mushrooms (primordia) appear, the temperature, light, humidity, and airflow must be adjusted to promote fruiting.
Additionally, fresh air is essential for mushroom growth. Carbon dioxide levels in the growing environment should be monitored and maintained at 0.08% or lower, depending on the cultivar. Proper ventilation is crucial, and commercial mushroom growing requires special houses equipped with ventilation systems.

Harvest the mushrooms
Harvesting is the final stage of mushroom cultivation. It involves collecting mature mushrooms at the optimal time, ideally just before spores are released. The mushroom harvest begins 15 to 21 days after casing, which is 7 to 8 weeks after composting starts. Mushrooms are picked over a period of 2 to 4 days in a 7- to 10-day cropping cycle, also known as a flush or break. Once the mature mushrooms are picked, the next flush moves towards maturity. Flush timing is managed through water, CO2, and temperature control.
When a crop becomes unproductive, it needs to be terminated. Before removing the crop, the spent mushroom substrate should be "pasteurised" with steam to prevent pests or disease-causing pathogens from contaminating neighbouring or subsequent crops. This process is called a "steam-off". The temperature should be no less than 150°F for at least 12 hours.
Mushroom growing is a complex process, but it can be rewarding. It is important to remember that each species has unique requirements, and observing their development is educational and rewarding. Patience and attention to detail are key.

Frequently asked questions
You can buy mushroom-growing kits that include most of the supplies you need. However, if you want to assemble the materials yourself, you will need a plastic tub or baking pan, mushroom spawn (mushroom seedlings), growing substrates such as compost, straw, sawdust, or coffee grounds, a damp towel, and a spray bottle.
Oyster, button, and shiitake mushrooms are the easiest for beginners.
Mushrooms need a dark, cool place to grow, such as a basement or crawl space. A dark drawer or cabinet will also work. You can grow mushrooms outdoors or indoors year-round.
First, place several handfuls of your chosen substrate into your tub or pan. Mix the spawn into the substrate and raise the temperature to 70 degrees. After 2-4 weeks, the spawn will have taken root in the substrate, which is called mycelium and looks like white fuzz. Drop the temperature to 55-60 degrees. After about a week, you will see some primordia forming in your bin, which will turn into pins. A couple of days later, you will see your first pins, which will soon grow into big adult mushrooms.
Mushrooms will be large enough to harvest after about three weeks, and you will be able to keep harvesting them for up to 60 days, depending on the species.
