Embarking on the journey of mushroom cultivation? Before diving in, it's essential to familiarize yourself with some fundamental terms and concepts. Let's break them down:


Think of the substrate as the 'soil' for mushrooms. It's the material on which the mushroom mycelium grows and derives its nutrients. Common substrates include hardwood sawdust, straw, and coffee grounds. For those looking for ready-to-use options, our sterilized rye bag with filter is a popular choice among cultivators. You can use this to make oyster mushroom spawn. You will not need mushroom grow kits if you learn how to make your own mushroom spawn and mushroom substrates.


Mycelium is the root system of mushrooms. It's a white, thread-like network that spreads throughout the substrate, breaking it down and absorbing nutrients. It's the mycelium that eventually gives rise to the fruiting bodies we recognize as mushrooms. Most of the time it is expanded on growing media like Malt extract Agar which is suitable for many oyster mushroom varieties. Most mushrooms generally will grow and expand on malt extract agar. Mushrooms are one of the most resilient organisms on this planet.


This is the stage where the actual mushroom bodies grow. After the mycelium has fully colonized the substrate, changes in environmental conditions, like light and temperature, trigger the mycelium to produce mushrooms.


Spawn is like the 'seed' for mushroom cultivation. It's a substrate that's been fully colonized by mycelium and is ready to be mixed with a bulk substrate to produce a larger batch of mycelium.


The process of introducing mushroom spawn to a fresh substrate is called inoculation. It's the first step in starting a new mushroom culture. Our whole oats mushroom spawn bag is perfect for beginners.


After inoculation, the mycelium starts to grow and spread throughout the new substrate. This phase is called colonization. It's crucial to maintain optimal conditions during this stage to ensure healthy growth.

The Lifecycle of an Oyster Mushroom:

Starting with inoculation, the mycelium colonizes the substrate. Once fully colonized, environmental triggers lead to the fruiting stage, where mushrooms emerge, mature, and eventually release spores, completing the cycle.

With these basics in hand, you're well-equipped to start your oyster mushroom cultivation journey!

Choosing the Right Substrate for All Types of Oyster Mushrooms

different mushroom substrates

When it comes to oyster mushroom cultivation, one of the most critical decisions you'll make is selecting the right substrate. Think of the mushroom substrate as the foundation of your mushroom farm. Just as plants need fertile soil to thrive, mushrooms require a nutrient-rich substrate to grow and produce bountiful yields. Oyster mushroom growing can be very rewarding if you dial in the mushroom substrate your mushrooms need to grow. We all want to grow lots of mushrooms, so its crucial to get everything correct.

Why is Substrate So Important?

The substrate provides essential nutrients for the mycelium, the root-like structure of mushrooms. A well-chosen substrate ensures that the mycelium has all it needs to grow vigorously and produce healthy fruiting bodies. Moreover, the type of substrate can influence the flavor, texture, and yield of your mushrooms. Choosing the correct substrate for growing oyster mushrooms is not as difficult as one might think. A well prepared substrate will produce healthy and vigorous mushroom mycelium. If you plan on growing them indoors as a project you can actually grow oyster mushrooms on cardboard.

Different Types of Substrates like Wood Based, Coffee Grounds and Tips for Growing

Let's delve into some of the most popular substrates used in oyster mushroom cultivation:

Hardwood Sawdust:

Pros: Hardwood sawdust is abundant and often inexpensive. It's rich in lignin, a compound that oyster mushrooms love to break down. This substrate often leads to high yields and is especially suitable for wood-loving species like the oyster mushroom.

Cons: It may require sterilization to eliminate any competing organisms. Additionally, sourcing pure hardwood sawdust without contaminants can sometimes be challenging.

Recommended Product: Wood Based Mushroom Substrate


Pros: Straw is another readily available and cost-effective substrate. It's easy to prepare and has a good water retention capacity, ensuring the mycelium stays hydrated.

Cons: Straw can be prone to contamination if not properly pasteurized. It may also not be as nutrient-dense as other substrates.

Recommended Product: Pasteurized Wheat Straw

Coffee Grounds:

Pros: An excellent way to recycle used coffee grounds, this substrate is rich in nitrogen, which can boost mushroom growth. It's also readily available for those who drink coffee regularly.

Cons: Coffee grounds can dry out quickly and may attract mold if not used promptly. It's essential to ensure the grounds are free from mold before using them as a substrate.


Pros: Cardboard is a surprising choice, but it's effective! It's an excellent way to recycle old boxes, and the cellulose content is a favorite for mycelium.

Cons: Cardboard alone might not be nutrient-rich enough for large yields. It's often best used in combination with other substrates or for small-scale cultivation.

For oyster mushroom cultivation we recommend you first source your mushroom culture from a reputable vendor such as Out Grow. Once you have your culture you will need to either make or purchase sterilized grain spawn to inoculate with your culture. Once your grain spawn fully colonizes, you can then add it to a bulk substrate suck as pasteurized straw or hard wood substrate.

Ingredients to get started:

  • Oyster Mushroom Culture
  • Sterilized Rye Berries
  • Pasteurized Straw

The Correct Substrate Will Help Your Mushrooms to Grow

Your choice of substrate will depend on various factors, including availability, cost, and the specific requirements of the mushroom you are trying to grow. For beginners, starting with a pre-prepared substrate like our Sterilized Rye Bag with Filter can simplify the process and increase the chances of success if your making mushroom spawn. Many different types of oyster oyster mushrooms are relatively easy to grow. There are a lot of different kinds of oyster mushrooms. The come in all different colors and sizes. To name a few popular one we have yellow oyster, phoenix oyster, Italian oyster, pink oyster (yes pink mushrooms) and many other oyster species. Growing on straw is a popular choice due to its availability and cost effectiveness. Also, Pleurotus ostreatus like to grow fast on straw due to its low nutrient composition. Growing mushrooms on cardboard is an even less expensive way to get started and reduces your carbon foot print by recycling. If your looking for a good substrate for growing oyster mushrooms, there are many to choose from. Enriched sawdust is also a common method of growing.

In conclusion, the substrate is the bedrock of your mushroom cultivation journey. By understanding the pros and cons of each type and tailoring your choice to your specific needs, you'll be well on your way to a fruitful harvest.

Setting Up Your Growing Environment

Embarking on the journey of growing oyster mushrooms is an exciting endeavor. However, before you see those delightful fungi sprouting, it's crucial to set up the right environment for them to thrive. Let's explore the essential elements of a mushroom-friendly habitat. Before you start growing, make sure you have your grow room or area set up and ready to go. Heck you can even grow mushrooms in a bucket if that's all you have. Growing indoors has both its pros and cons.

Indoor vs. Outdoor Cultivation:

Indoor Cultivation:

Pros: Growing mushrooms indoors offers a controlled environment, protecting your crop from pests and unpredictable weather conditions. It allows for year-round cultivation, regardless of the season.

Cons: It may require specialized equipment to maintain the right temperature, humidity, and light conditions.

Outdoor Cultivation:

Pros: Outdoor cultivation can be more cost-effective, as nature provides many of the necessary conditions. It's also a great way to utilize garden space.

Cons: You're at the mercy of natural elements. Unpredictable weather, pests, and competing fungi can pose challenges.

Growing Oyster Mushrooms Outside

While indoor cultivation has its benefits, many growers enjoy producing oyster mushrooms outdoors. This provides a cost-effective way to grow that leverages natural conditions.

When starting to grow oyster mushrooms outside, select a shady spot protected from wind. Oysters thrive in the same temperatures as indoors - around 60-75°F. Avoid areas that drop below freezing.

Prepare an outdoor substrate mix in a wide, shallow wooden box, plastic bag or bin. Cardboard and straw make great outdoor medium. Mix the spawn throughout the substrate.

Monitor humidity levels. Use plastic bags or tarps to retain moisture if needed. Mist the mushrooms directly versus overhead to reduce risk of oyster mushroom spores irritating allergies.

Inspect the developing mushrooms daily. Harvest promptly once caps start to flatten and curl under. Refrigerate immediately after picking to preserve freshness.

Outdoor cultivation provides a more hands-off way to grow oyster mushroom varieties like yellow oyster and Italian oyster mushrooms. You get to see mushrooms form right in their natural environment. With some protection from weather swings, oyster mushrooms can thrive outdoors, providing abundant seasonal harvests.

This covers key considerations like temperature, humidity control, substrate mix, and harvesting for successfully cultivating oyster mushrooms outside. Let me know if you would like me to expand or modify this section further.

The Role of Humidity and Fresh Air:

Mushrooms aren't like typical plants. They don't photosynthesize, but they do need fresh air and the right humidity levels to grow.

Humidity: Oyster mushrooms thrive in a moist environment. It ensures that the mycelium remains moist, promoting healthy growth. A lack of water can lead to smaller yields and dry, cracked mushrooms.

Fresh Air: While it might seem counterintuitive, mushrooms need fresh air to grow. Fresh air exchange helps in the release of carbon dioxide and intake of oxygen, essential for mushroom fruiting. Without adequate air exchange, you might notice elongated stems and small caps, indicating the mushrooms are "reaching" for more air.

Essential Tools and Equipment to Grow Oyster Mushrooms at Home:

mushroom substrate bags

Oyster mushrooms require specific environmental conditions to fruit successfully. The right tools and equipment help monitor and control factors like humidity, airflow, and temperature.

Humidifiers or misters are useful for maintaining the high humidity oyster mushrooms need, around 80-90%. Without sufficient humidity, the developing mushrooms can dry out or crack. Hygrometers precisely track moisture levels, allowing you to adjust humidity as needed.

Fans and ventilation tubing help provide fresh air exchange. Oxygen is critical for mushroom growth. Stagnant air can also increase chances of contamination. Fans supplement natural airflow while ventilation tubes with HEPA filters filter incoming air.

For indoor cultivation, grow bags allow pasteurization or sterilization of substrate right in the bag. Built-in filter patches prevent contamination while allowing gas exchange. Avoid bags without filters, as these can lead to harmful mildew growth. Choosing the right bag size for your available space is key.

Lastly, digital thermometers help monitor temperatures, which should be kept in the ideal range of 55-75°F for oysters. Consistent temperature control prevents heat damage. With the right environmental controls in place, oyster mushrooms can thrive in both indoor and outdoor settings. Careful monitoring and adjustments are key for a successful harvest.

The Inoculation Process

If you're new to the world of mushroom cultivation, you might be wondering, "What exactly is inoculation?" Well, let's dive into this essential step in the mushroom-growing journey and demystify the process.

What is Inoculation?

Inoculation is the pivotal first step that kicks off the mushroom cultivation process. It involves introducing mushroom spawn into a prepared substrate to establish the initial mycelial culture. The spawn contains mycelium, which are thread-like filaments that make up the vegetative structure of a mushroom. This mycelium will colonize and spread throughout the substrate after inoculation.

Several types of mushroom spawn can be used for inoculation, including grain spawn, sawdust spawn, plug spawn or liquid culture syringes. Grain spawn consists of nutritious grains like rye or millet that have been colonized by mycelium. Sawdust spawn features mycelium grown on hardwood sawdust. Plug spawn are literal plugs of myceliated wood or sawdust. Liquid culture features mycelium suspended in a sterile liquid medium. Each spawn type has its advantages depending on the mushroom species and available substrate.

The substrate provides nutrients and a supportive matrix for the mycelium to colonize after inoculation. Nutrient-rich substrates for oyster mushrooms include wood chips, straw, coffee grounds, supplemented sawdust or grain mixtures. Proper substrate preparation and sterilization prior to inoculation helps prevent contamination. In essence, inoculation allows the mushroom "seed" (spawn) to germinate in its growing medium (substrate), initiating the first phase of the cultivation process.

Steps to Inoculate Your Substrate:

  1. Preparation:

    Creating a sterile working environment is crucial when inoculating mushroom substrate to prevent contamination. Start by thoroughly cleaning your workspace, whether it's a countertop, table, or inoculation station. Remove any clutter and wipe down all surfaces with disinfectant. Bleach solution or isopropyl alcohol work well for surface sanitization.

    Once cleaned, allow the area to dry fully. Turn off any fans, air circulation, or forced heating during the inoculation process to prevent airborne contaminants from dispersing. Some cultivators prefer to work in front of a laminar flow hood, which uses HEPA filtration to provide particle-free air circulation. Others may use a DIY still air box, crafted from clear plastic sheeting. These tools provide added sterility but are not mandatory for beginners.

    Right before inoculation, spray your cleaned workspace and tools with a disinfectant like 70% isopropyl alcohol for the tools and Lysol for the air. This will decontaminate any remaining microbes. Wait a few minutes for surfaces to dry before beginning. Work as efficiently as possible to minimize exposure. Maintain cleanliness by wearing gloves and a face mask. Avoid directly breathing over open containers and substrates during inoculation. Follow stringent sanitization protocols from start to finish, and your mushroom spawn will have the greatest chance of colonizing contamination-free.

  2. Choose Your Substrate:

    Choosing an optimal substrate is crucial for successful oyster mushroom cultivation. Oyster mushrooms thrive on substrates high in lignin and cellulose. Popular options include hardwood sawdust, straw, coffee grounds, or a mixture of these. Hardwood sawdust, like oak or maple, provides abundant nutrition to fuel mycelial growth. Do not use Conifer or Cedar as those are not good for general mushroom cultivation. Straw offers a cost-effective and widely available choice. Spent coffee grounds are also an excellent reusable substrate. For beginners, using pre-pasteurized mushroom substrate bags with injection ports allows for an easy, no-fuss inoculation.

  3. Introduce the Spawn:

    Once you have your sterilized grain substrate, use a sterilized syringe to inject liquid mushroom culture through the injection port. Inoculate the bag with 6cc of liquid culture per pound of grain substrate. After injecting, shake the bag to evenly distribute the liquid culture throughout.

  4. Seal and Store:

    After inoculation, store the bags in a dark, room temperature area around 75-80°F. Avoid disturbing the bags for the next three to four weeks during colonization. Mycelium grows best undisturbed. Check bags periodically to monitor progress. You should see white, cottony mycelium spreading throughout the bag. This web-like network will eventually turn into a solid white mass when fully colonized.

  5. Monitor:

    Over the next few weeks, you'll notice the mycelium growing and colonizing the substrate. It's a fascinating process, reminiscent of a white web spreading throughout.

  6. Patience is Key:

    The colonization process can take several weeks. It's essential to be patient and avoid disturbing the substrate too much during this time.

Inoculation is a critical step in mushroom cultivation. By introducing the mycelium to a nutrient-rich environment, you're setting the stage for a fruitful harvest. For a step by step guide into the inoculation process and its significance, the article on Cultivation of Oyster Mushrooms offers valuable insights.

Growing Oyster Mushrooms in a Bucket

Don't have much space? No problem! Oyster mushrooms can easily be grown in a simple 5-gallon bucket. This small-scale method is great for beginners.

Start with a plastic 5-gallon bucket and lid. Drill 1/4-inch holes spaced 2-3 inches apart in rows along the sides of the bucket for airflow. On the lid, drill a pattern of slightly larger 1/2-inch holes spaced 3-4 inches apart. The holes should start 2 inches from the bottom and end 2 inches from the rim.

Next, add your substrate material. Shredded hardwood like oak makes an excellent bucket substrate. You can also use straw or coffee grounds. Fill the bucket about 3/4 full with your substrate. Pasteurize the substrate by pouring boiling water over it in the bucket. Let soak for at least one hour.

Once pasteurized, drain excess water. Allow the substrate to cool before inoculating by scattering oyster mushroom grain spawn over the top. Gently mix for even distribution. Place the lid on to retain moisture.
Keep the inoculated bucket around 70-80°F out of direct sunlight. After a few weeks, a thick white mycelium will form. Remove the lid and mist daily to provide humidity. Mushrooms will soon fruit from the holes.

Harvest mushrooms by twisting near the base when 3-5 inches tall. Continue misting between flushes. With the right conditions, you can grow pounds of oyster mushrooms in just a 5-gallon bucket!

Monitoring and Caring During Colonization

The colonization phase is crucial for growing healthy and contamination-free oyster mushrooms. Follow these tips:

Maintain temperatures around 70-75°F, high humidity, and complete darkness. Store inoculated bags undisturbed in a closet or box.

Check for signs of growth like thick, white, musty mycelium versus contamination like colored mold or foul smells. Discard any contaminated bags promptly.

Have patience. Colonization takes several weeks as the mycelium slowly digests nutrients and spreads in the substrate. Avoid excessive peeking or disturbing the bags.

Don't get discouraged by contamination - it's a common part of the learning process. Thoroughly sanitize work areas and retry.

With attentive monitoring, ideal growing conditions, and contamination vigilance, the nutritious substrate will fully colonize, preparing the mycelium for fruiting. Proper care in this phase leads to abundant, healthy oyster mushrooms down the road.

Initiating the Fruiting Conditions

After the colonization phase, the next exciting step in mushroom cultivation is initiating the fruiting conditions. This phase is where you'll start to see the actual mushrooms emerge and grow. Let's delve into how to transition from colonization to fruiting and the necessary adjustments you need to make.

Transition from Colonization to Fruiting:

The transition from colonization to fruiting is marked by a few key changes in the environment. Once the substrate is fully colonized, which means it's covered in a dense white mycelium, it's time to expose the mycelium to fresh air, light, and cooler temperatures. These changes signal the mycelium that it's time to produce mushrooms.

Adjusting Light:

Unlike the colonization phase, which requires darkness, the fruiting phase requires light. A simple 6500K daylight spectrum bulb can be used for about 12 hours a day. Natural indirect sunlight works well too. Light not only triggers mushroom growth but also directs it. Mushrooms will grow towards the light source, so ensure it's placed for even growth. According to a study from ScienceDirect, light exposure plays a significant role in the growth and development of oyster mushrooms.

Temperature and Humidity Adjustments:

While colonization prefers warmer temperatures, fruiting conditions for oyster mushrooms like the Grey Oyster and the Lambert 123 require slightly cooler conditions, ideally between 55-70°F (13-21°C).

Humidity is equally crucial. The environment should be kept at high humidity, around 90-95%. This can be achieved using a humidifier or by misting the growing area with water several times a day. However, ensure there's adequate air exchange to prevent mold growth. The University of Florida's guide on growing oyster mushrooms provides an in-depth look at the importance of these conditions.

Fresh Air Exchange (FAE):

Mushrooms produce carbon dioxide as they grow, and too much of it can hinder their development. Therefore, it's essential to provide fresh air exchange at least 3-4 times daily. This can be done by fanning the growing area or using a small fan. However, be cautious not to dry out the substrate. An article from AMB Express highlights the importance of FAE in the growth and yield performance of oyster mushrooms.

In conclusion, transitioning to the fruiting phase requires careful adjustments to light, temperature, and humidity. By maintaining the right conditions and monitoring your mushrooms closely, you'll be on your way to a successful harvest. Remember, every mushroom variety might have its nuances, so always be open to learning and adjusting as you go.

Harvesting Your Oyster Mushrooms

harvesting mushrooms

The moment you've been waiting for has finally arrived! After weeks of careful cultivation, it's time to harvest your oyster mushrooms. But how do you know when they're ready? And once you've picked them, how should you store and preserve them? Let's explore.

When to Harvest:

Determining the optimal time to harvest your oyster mushrooms takes careful observation. Monitor the mushroom caps closely as they mature. Oyster mushrooms are best picked when the caps are partially opened but still retain a slight curl under the edges. At this stage, the caps will appear round and blob-like. Allowing the caps to flatten completely is a sign you've waited too long. The gills underneath will be exposed, leading to spore release and potential allergy irritation if growing indoors. For maximum flavor and texture, harvest the mushrooms while young and tender. According to a guide by Instructables, the window for prime harvesting is when the caps are 1.5 to 3 inches wide. Mushrooms this size are still firm with a bouncy texture, unlike the softness of over-mature specimens.

Here are some visual indicators that your oyster mushrooms are ready for harvesting:

  • Caps are partially open with a curled under edge
  • Gills are not yet exposed
  • Caps are round and blob-like, not flattened
  • Diameter is 1.5-3 inches
  • Stems are firm and fresh, not overly long

How to Harvest:

When harvesting, be gentle with the delicate oyster mushrooms. Use clean gloves or hands to grasp each mushroom near the base of the stem. Apply a slight twisting motion as you pull to detach the mushroom from the substrate. Never yank or apply excess force as this can damage the mycelium network. The mushrooms should separate easily if picked at the right maturity stage. To avoid bruising, handle the harvested mushrooms with care and avoid overcrowding them. Place the harvested mushrooms in a breathable container like a basket or tray. For a visual guide, check out the step-by-step harvesting tutorial by the Illinois Department of Natural Resources.

Storing and Preserving the Harvest:

For maximum freshness, cook and consume the oyster mushrooms as soon as possible after harvesting. If you need to store them for a short duration, place the mushrooms in a paper bag or box, never plastic, and refrigerate for up to one week. To extend shelf life, consider drying or freezing your harvested mushrooms. Drying involves dehydrating the mushrooms using a food dehydrator or oven at low temperature, usually between 90-100°F. Allow the slices to dry completely until brittle with no moisture left. Store the dried mushrooms in airtight jars or bags. For freezing, briefly blanch the mushrooms then spread out on trays to freeze individually. Finally, transfer the frozen mushrooms to freezer bags or containers. With proper drying and freezing techniques, you can enjoy your home-grown oyster mushrooms for months beyond the harvest.
