Size: Reishi mushrooms can vary in size, but they typically have a diameter of 5 to 25 centimeters (2 to 10 inches). The caps can be quite large and impressive, especially in mature specimens.

Texture: The surface of Reishi mushrooms is smooth and shiny, often described as having a lacquered appearance. When touched, they have a firm and woody texture.

It's important to note that Reishi mushrooms can exhibit some variations in appearance, especially due to different species and environmental factors. For example, there are different color variations, including red, purple, black, and even yellow Reishi mushrooms. Additionally, the texture and shape may differ slightly between species.

Can You Grow Reishi Mushrooms at Home?

Growing reishi mushrooms at home can be a rewarding and enjoyable experience. It could also be a way to access the many potential health benefits of this medicinal mushroom.

Here is a step-by-step guide on how to grow reishi mushrooms at home:

Choose a growing method: There are a few different methods for growing reishi mushrooms at home, including growing on logs, growing on sawdust, or using a mushroom kit. Each method has its advantages and disadvantages, so it's important to choose the one that works best for your needs and resources.

Obtain mushroom spawn: To grow reishi mushrooms, you'll need to start with mushroom spawn, which is the mycelium or vegetative part of the fungus. You can purchase reishi mushroom spawn online or from a specialty mushroom supplier.

Prepare your growing substrate: Depending on your chosen growing method, you'll need to prepare your growing substrate. If you're cultivating on logs, you'll need to drill holes in the logs and inoculate them with mushroom spawn. If you're growing on sawdust, you'll need to mix the spawn with sterilized sawdust and pack it into containers. If you're using a mushroom kit, the substrate will already be ready for you.

Inoculate your substrate: Once you've prepared your growing substrate, you'll need to inoculate it with mushroom spawn. This step involves mixing the spawn with the substrate and packing it tightly into the growing containers or logs.

Incubate your mushroom spawn: After inoculating your substrate, you'll need to incubate it in a warm, dark location to allow the mushroom mycelium to colonize the substrate. This process can take anywhere from a few weeks to several months, depending on the growing method and conditions.

Introduce fresh air and light: Once the mycelium has colonized the substrate, it's time to introduce fresh air and light to trigger fruiting. This can be done by moving the logs or containers to a location with good air circulation and indirect sunlight.

Harvest your mushrooms: After a few weeks, small reishi mushrooms will begin to form on the substrate. You can harvest them when they are fully mature and the caps are fully formed. It's important to harvest them promptly, as they can quickly become too tough and woody if left on the substrate for too long.

You may wonder how long it grows Reishi mushrooms. The answer to that question depends on how and where you will grow your mushrooms. But Reishi mushrooms reach maturity more quickly in a greenhouse. Cooler temperatures can slow down the process. Reishi mushrooms can tolerate both high and low levels of CO2 and you can grow them in a range of recycled containers.

The time the start of the spawn run to complete the colonization is about 20 days, then the mushrooms start to finger-like antler growth which takes about 28 days. After the antlers reach 1 to 3 inches, the fruiting blocks are ready to use and planting.

After the antlers have grown to your desired length, open or cut the bag to increase oxygen levels. Reishi can take a very long to mature before harvesting.

Fruiting is the longest stage and it can take up to six weeks for Reishi mushrooms to reach maturity from the time pins first appear.

It takes 9-12 months before your Reishi begins to fruit.

How Can You Grow Reishi Mushrooms?

There are different ways to grow Reishi mushrooms. Below are the four known methods of growing Reishi mushrooms which I briefly discussed for your consideration:

Growing Reishi Mushrooms Using Grain Spawn

Create or purchase lids: You will need jar lids for your grain spawn. It is recommended to use Mycology Supply's jar lids because they have a built-in filter, self-healing injection port, no drilling, and no assembly required. These lids will help keep contaminants out while allowing air exchange.

Select a grain to make the grain spawn: The most commonly used grains for Reishi mushroom cultivation are rye, wheat, or millet grains. It is important to choose high-quality grain that is free of mold or other contaminants.

Soak and simmer the grain: Soak the grains in water for at least 12 hours to soften them for mycelium growth. The grains should then be simmered for 15 minutes at a low temperature on the stove. Drain the grains in a sieve and set them aside to dry for an hour.

Fill the jars with grain: Once drained, fill the jars ¾ full with the grains and leave some room for shaking. After closing the lid, wrap tin foil around the top to prevent water from entering during sterilization.

Sterilize the grain: To eliminate any contaminants, sterilize the grain by using a pressure cooker. This can be done by placing the jars in the pressure cooker, adding a half inch of water, closing the lid, and bringing the pressure up to 15 psi. Let the pressure remain at this level for at least 90 minutes.

Cool the jars: To prevent the Reishi liquid culture from being killed, it is crucial to cool the jars to room temperature before inoculating them.

Inoculate the grain spawn: When inoculating the grain spawn, apply a sterile technique such as a laminar flow hood or a clean air box to avoid contamination. Use a 10cc syringe with a long needle to inject the liquid culture into the grain jar’s self-healing port, sanitizing the needle with a blow torch and cooling it with a paper towel soaked in rubbing alcohol. Fill the syringe with 5cc of liquid culture and inject it into the jar.

Store the jars: For this step, you should place the jars at room temperature until they show signs of colonization, which usually takes around two weeks. Once colonized, transfer the jars to plastic bags filled with moist sawdust-based substrates like hardwood chips or straws to encourage further growth of the mycelium.

Harvest the Reishi mushrooms: When the Reishi mushrooms have fully grown and turned a dark red-brown color, they are ready to be harvested. Since they take a few months to grow, patience is essential. Cut the mushrooms off at the base to harvest them.

Growing Reishi Mushrooms Using Agar Cultures

Source spores or mushroom cultures: Obtain spores or mushroom cultures from a reliable source. These can be purchased from reputable suppliers specializing in mushroom cultivation.

Sterilize equipment: Ensure that all equipment, including jars, Celltreat Sterile Petri dishes, and culture media, is properly sterilized. This step is crucial to prevent the growth of unwanted microorganisms. Sterilize the equipment using methods such as autoclaving or pressure cooking.

Prepare culture media: Potato Dextrose Agar (PDA) or Malt Extract Agar (MEA) are ideal culture media for Reishi mushrooms. Follow the instructions to prepare the agar mix by mixing powdered agar with water and heating it to the appropriate consistency. Sterilize the agar mixture in a pressure cooker at 15 PSI for 20 minutes. After sterilization, allow the pressure cooker to depressurize fully or wait at least an hour before opening.

Cool the agar mixture: Place the sterilized agar mixture in a warm water bath and monitor the temperature using a thermometer. The agar should be cooled to room temperature before pouring it onto plates.

Prepare agar plates: You can either purchase pre-made agar plates online or create your own. In a sterile workspace, pour the cooled agar mixture into the Celltreat Sterile Petri dishes to create the agar plates.

Inoculate the plates: Using a sterilized needle or scalpel, or by allowing spores to fall onto the agar surface, inoculate the plates with the Reishi mushroom culture. Make sure to work in a laminar flow hood or a clean environment to maintain sterility.

Seal and incubate the plates: Seal the Petri dishes with parafilm or plastic wrap to prevent contamination. Place the sealed plates in a warm, dark location with a temperature between 70-80°F (21-27°C). This will provide optimal conditions for the growth of the Reishi mushroom mycelium.

Monitor mycelium growth: After about a week or two, the mycelium should have fully colonized the agar, appearing as white fluffy growth on the surface. This indicates the successful growth of the Reishi mushroom mycelium.

Transfer mycelium to a jar: Using a sterilized agar punch or a similar tool, carefully transfer a piece of the fully colonized mycelium to a sterilized jar. This step allows you to create a liquid culture for further propagation.

At this point, you can continue the cultivation process by following specific techniques for liquid culture, spawn production, and fruiting. These steps often involve transferring the mycelium to a suitable substrate, such as sterilized grain or wood chips, and providing appropriate environmental conditions for fruiting.

It's worth noting that the process described above provides a general overview of growing Reishi mushrooms using agar culture. However, successful cultivation may require additional adjustments and specific techniques depending on the specific requirements of the Reishi mushroom strain being grown.

Growing Reishi Mushrooms Using Liquid Cultures

Prepare equipment: Obtain Mycology Supply Jar Lids and 1000 mL jars. These lids come with built-in filters and self-healing injection ports, eliminating the need for drilling holes or making your own lids.

Create a sugar solution: Heat 2400 mL of distilled water and dissolve 100 mL of Karo Light Corn Syrup to make a 4% sugar solution. Mix in 4 grams of soya peptone. This will yield approximately 8-quart jars of the solution. Fill each jar with 300 mL of the sugar solution.

Sterilize containers and medium: Place the jars filled with the sugar solution and covered with lids into a pressure cooker. Add a few quarts of water to the bottom of the pressure cooker to create steam. Sterilize the containers and medium by heating at 15 psi for at least 25 minutes. Allow the pressure cooker to cool to room temperature before removing the jars. Ensure that the lids are tightly secured.

Inoculate the liquid culture: Work in a sterile environment, ideally near a laminar flow hood. Sterilize your work area, tools, and jars using 70% rubbing alcohol. Use a scalpel to transfer a small piece of Reishi mushroom mycelium from an agar plate into the liquid culture medium. After each transfer, sterilize the scalpel with a blow torch to maintain sterility.

Incubate the liquid culture: Place the inoculated jars in a dark location at room temperature (around 70-80°F or 21-27°C). Allow the mycelium to colonize the liquid culture medium over a period of 4-8 weeks. During this time, periodically shake the jars gently to break up the mycelium and promote even growth.

Storage and usage: Once the mycelium has fully colonized the liquid culture medium, you can store it in a refrigerator for future use or use it immediately to inoculate a substrate for mushroom cultivation. Before using the liquid culture, it's important to test each jar's viability by inoculating a small grain jar as a control. This will help you identify potential contaminants early on and ensure successful mycelium growth.

Liquid culture can be susceptible to contamination, even if it appears visually unaffected. Performing tests with a control jar allows you to monitor for contamination and take necessary precautions to ensure a healthy and successful mushroom cultivation process.

Growing Reishi Mushrooms Using Grain Spawn

Obtain or create suitable lids: Use jar lids that have a built-in filter and a self-healing injection port. These lids eliminate the need for drilling holes and provide a convenient way to introduce the liquid culture.

Select a grain substrate: Choose a high-quality grain such as rye, wheat, or millet. Ensure that the grains are free from mold or other contaminants.

Soak and simmer the grains: Soak the grains in water for at least 12 hours to hydrate them. After soaking, simmer the grains on low heat for 15 minutes. This process softens the grains and prepares them for mycelium growth. Drain the grains using a strainer and allow them to dry for about an hour.

Fill jars with grains: Fill the sterilized jars about three-quarters full with the dried grains. Leave some headspace for shaking and mycelium growth. Close the lids tightly and wrap tin foil around the tops to create a barrier.

Sterilize the grain jars: Place the jars in a pressure cooker with about a half inch of water in the bottom. Close the pressure cooker and bring the pressure up to 15 psi. Maintain this pressure for a minimum of 90 minutes to ensure thorough sterilization of the grain substrate.

Cool the jars: Allow the sterilized jars to cool to room temperature before proceeding to inoculation. Cooling the jars is crucial to prevent the heat from damaging the Reishi liquid culture.

Inoculate the grain jars: In a sterile environment such as a laminar flow hood or a sterile air box, use a syringe with a long needle to inoculate the grain jars with Reishi liquid culture. Sterilize the needle using a blow torch and cool it with a paper towel soaked in rubbing alcohol. Insert the needle into the self-healing injection port of the grain jar lid and inject about 5cc of the liquid culture. Repeat this process for each jar.

Incubate the grain jars: Store the inoculated grain jars at room temperature until signs of colonization appear. This typically takes about two weeks. During this time, the Reishi mycelium will grow and colonize the grain substrate.

Transfer to substrate bags: Once the grain jars are fully colonized, transfer the colonized grains to plastic bags filled with a moist sawdust-based substrate such as hardwood chips or straws. This transfer provides a suitable environment for further mycelium growth.

Allow for substrate colonization: Keep the bags at room temperature in a dark and humid environment. The Reishi mycelium will continue to colonize the substrate over the next several weeks.

Provide fruiting conditions: Once the substrate is fully colonized, introduce the bags to fruiting conditions. This includes providing indirect light, maintaining high humidity levels, and keeping the temperature between 70-80°F (21-27°C). Adequate air circulation is also important.

Monitor and harvest: Monitor the bags closely for the formation of Reishi mushrooms. They will appear as distinct and recognizable fruiting bodies. Harvest the mature mushrooms by carefully cutting or twisting them from the substrate.

Remember to maintain a clean and sterile environment throughout the process to minimize the risk of contamination and ensure a successful harvest of Reishi mushrooms.
