  • Mycelium: the root-like part of the fungus that consume food and will eventually form the mushroom fruit
  • Substrate: the material that the mushrooms will grow on, such as sawdust, straw, or compost
  • Fruiting: the stage when the mushroom fruit appears and is ready to be harvested

🌱 Now that we've covered the basics, let's get into the nitty-gritty of growing mushrooms at home.

Step 1: Choosing the Right Mushroom Species 🍄

When it comes to growing mushrooms, it's important to pay close attention to the growing conditions. Different mushroom species have varying requirements for temperature, humidity, light, and substrate material. Here are some general growing conditions to keep in mind, as well as some recommended conditions for beginners:

  • Temperature: 65-75°F (18-24°C)
  • Humidity: 90-95%
  • Light: Low to medium indirect light
  • Substrate material: Ready-to-use mushroom growing kits or pre-sterilized substrates

There are several popular mushroom species that are great for beginners to grow. Here are some of the most popular ones and why they are so popular:

  • Button mushrooms (Agaricus bisporus): These mushrooms are widely cultivated and commonly found in grocery stores. They are easy to grow and have a mild flavor.
  • Shiitake mushrooms (Lentinula edodes): These mushrooms have a rich, meaty flavor and are commonly used in Asian cuisine. They are also fairly easy to grow.
  • Oyster mushrooms (Pleurotus ostreatus): These mushrooms have a delicate, nutty flavor and come in a variety of colors. They are relatively easy to grow and produce a high yield.
  • Lions Mane mushrooms (Hericium erinaceus): These mushrooms have a unique appearance and a delicate, seafood-like flavor. They are a bit more challenging to grow, but still doable for beginners.

Here is a table comparing the different popular mushroom species:

Step 2: Preparing the Substrate Material 🍄

Once you've chosen the mushroom species, it's time to prepare the substrate material. The substrate is the material that serves as a base for the mycelium to grow on. The substrate needs to be prepared carefully to ensure the best quality and yield of mushrooms. Here's how to prepare the substrate material:

  1. Choosing the right substrate material is a critical step in successfully growing mushrooms. Different mushroom species have different nutritional requirements, and they need specific substrates to grow. Here are a few examples of popular mushrooms and their ideal substrate materials:

Here's a table comparing popular mushrooms and their ideal substrate materials:

Note: Please keep in mind that the preferred substrate and fruiting temperature can vary depending on the strain of the mushroom species being grown.

Pasteurize the substrate: Pasteurization helps to kill any harmful bacteria, fungi, or other microorganisms that might compete with your mushroom spawn. Here are the steps to pasteurize your substrate:

  • Fill a large pot with water and bring it to a boil.
  • Add the substrate material to the boiling water and stir it well.
  • Cover the pot with a lid and allow it to simmer for 1-2 hours.
  • Drain the substrate and let it cool.
  1. Add supplements: Supplements such as gypsum, calcium carbonate, or rice bran can help to increase the nutrient content of the substrate and promote the growth of the mycelium. Below the typical amount used in the field: 
  • Gypsum: 1-2 tablespoons per quart of substrate
  • Calcium carbonate: 2-3 tablespoons per quart of substrate
  • Rice bran: 1-2 cups per 5-10 pounds of substrate

It's important to note that the exact amount of supplements you use may vary depending on the specific mushroom species and substrate you are using.

  1. Adjust the pH level: The pH level of the substrate should be between 6 and 7. Use a pH meter to test the pH level and add lime or vinegar to adjust the pH level if needed.
  2. Conduct a capacity test: Before adding the spawn to the substrate, conduct a capacity test to ensure that the substrate is not too wet or too dry. To do this, squeeze a handful of substrate tightly in your hand. If water drips out, the substrate is too wet and needs to be drained. If the substrate crumbles, it is too dry and needs to be misted with water until it reaches the right consistency.
  3. Pack the substrate: Pack the substrate material into a container or bag and leave some space at the top for the mushroom spawn.

By following these steps, you can prepare a high-quality substrate material for your mushroom growing project.

Step 3: Spawning 🍄

Now that you have your substrate prepared, it's time to add the mushroom spawn to it. This will introduce the mycelium to the substrate and start the colonization process. Here's how to do it:

  1. Sanitize the workspace and tools: Proper sanitation is crucial to avoid contamination during spawning. Make sure to thoroughly clean your workspace and tools with a disinfectant such as isopropyl alcohol or hydrogen peroxide. Additionally, use gloves and a mask to prevent the introduction of harmful bacteria or other microorganisms.
  2. Inoculation: Take a sterile syringe filled with mushroom spawn and inject it into the substrate material. You can also sprinkle the spawn onto the substrate if it's in a bag.
  3. Mix: After inoculating, mix the substrate thoroughly to evenly distribute the spawn throughout the material. Wear gloves to avoid contamination.
  4. Incubation: Once mixed, place the substrate in a warm and dark place. The ideal temperature for incubation is between 70-80°F. The mycelium will start to colonize the substrate over the next few weeks.
  5. Be extra patient: After a few weeks, you'll start to see white mycelium growing throughout the substrate. This is a good sign that the colonization process is going well. Wait until the entire substrate is fully colonized before moving on to the next step. It is important to don't disturb the mycelium during this period. Keeping mycelium undisturbed a is key,  checking it every hour won't make it grow any faster :)

Note: If you're using a pre-made mushroom growing kit, the spawn will already be mixed in with the substrate. All you need to do is follow the kit's instructions for incubation and wait for the mushrooms to grow.

Step 4: Casing 🌰🌱

Casing is an important step in the process of growing mushrooms, as it provides a layer of nutrients and moisture to the substrate that helps the mycelium grow and develop mushrooms. Here's how to do it:

  1. Prepare the casing material: Casing material can be made from a variety of ingredients, including peat moss, vermiculite, and coconut coir. You'll want to mix the material with water until it's damp but not soaking wet.
  2. Apply the casing layer: Spread the casing material over the top of your substrate, making sure it's evenly distributed and about 0.5-2 inches thick.
  3. Cover and incubate: Cover the casing layer with plastic wrap to create a humid environment and let it incubate for about a week, until you see the mycelium starting to grow through the casing layer.
  4. Remove the plastic wrap: Once the mycelium has started to grow through the casing layer, remove the plastic wrap and let the mushrooms grow.

🍄Tip: You can add additional nutrients to your casing layer by mixing in materials like gypsum, lime, or calcium carbonate. This can help to promote healthy mushroom growth and increase yields.

Step 5: Pinning and Fruiting 🌱🍄

After the casing layer has been applied, it's time for the mushrooms to start forming. This is called pinning, and it's when tiny bumps appear on the surface of the casing layer. These bumps will eventually grow into mushrooms.

Here are some tips for successful pinning and fruiting:

  • Keep the humidity level between 85-90% and the temperature around 70-75°F (21-24°C) to encourage mushroom growth.
  • Mist the casing layer with water several times a day to maintain the proper moisture level.
  • Provide adequate light to stimulate fruiting. This can be achieved with a grow light or natural sunlight if the growing chamber is located near a window.
  • Harvest the mushrooms when the caps are fully opened, but just before the spread the spores. Use a sharp knife to cut the mushrooms at the base of the stem.

With proper care and attention, your mushroom grow kit should produce a bountiful harvest of delicious and nutritious mushrooms for you to enjoy.

Pro Tips:

  • If you don't have a hygrometer to measure humidity levels, you can control humidity by misting the substrate and casing layer lightly with water using a spray bottle.
  • Avoid over-saturating the substrate or casing, as this can lead to mold growth.
  • Monitor the appearance of the substrate and casing layer for signs of dryness or excess moisture and adjust misting as necessary. You want to see humid and small droplets of water in the case walls as a good sign of humidity level. If you have water accumulation in the bottom of the substrate you need to reduce the humidity level or drain the substrate to avoid contamination.

Step 6: Harvesting and Trimming

Congratulations, you’ve grown your mushrooms! The final step is to harvest and trim them properly. Here are some tips to ensure that you get the most out of your harvest:

🍄 Harvest your mushrooms when they are mature, but before the veil under the cap breaks. This is when the mushrooms are the most potent.

🍄 Use a clean pair of scissors to trim the mushrooms at the base of the stem. Be gentle so as not to damage the surrounding mycelium.

🍄 Remove any debris or substrate material from the harvested mushrooms.

🍄 Store your mushrooms in a paper bag or container with a paper towel to absorb any excess moisture. This will help to prevent mold growth.

🍄 Trim your mushrooms by removing the stems and any bruised or discolored spots.

🍄 Your harvested mushrooms can be eaten fresh, cooked, or dried for later use. Enjoy!

By following these simple steps, you can grow your own delicious and nutritious mushrooms. Happy growing!
