Mushroom Growing Guide For Beginners And Experts

#1 The Basics Of The Grow Guide

Mushrooms, nature’s hidden gems, have fascinated humans for centuries. Whether you’re a culinary enthusiast, a medicinal seeker, or simply curious, understanding this mushroom growing guide fundamentals can be rewarding and enlightening. In this section, we’ll delve into the core factors involved with mushroom growing: substrate, lighting, humidity, and airflow. Let’s embark on this mycological journey and uncover the secrets of mushroom grow kits.

Substrate/growing medium

Unlike plants, they don’t derive their nutrients from soil and sunlight. Instead, they thrive on organic matter, breaking it down and extracting essential nutrients. This organic matter, known as the substrate, plays a pivotal role in mushroom cultivation. The choice of substrate in a mushroom growing kit can significantly influence the mushrooms’ yield, growth rate, and health. Let’s explore some of the most commonly used substrates for growing mushrooms.

Types of Substrate For growing Mushrooms

Wheat Straw:

Pros: Wheat straw is famous for many mushroom varieties, especially oyster mushrooms. It’s abundant, inexpensive, and provides a good structure for the mycelium to colonize.

Cons: It may require pasteurization or sterilization to eliminate any competing organisms.

Hardwood Sawdust:

Pros: Many wood-loving mushrooms, like shiitake and maitake, prefer hardwood sawdust. It offers a dense nutrient profile and can be mixed with other supplements to boost growth.

Cons: It can compact easily, hindering mycelium growth if not properly aerated.

Coco Coir:

Pros: Coco coir, derived from coconut husks, is a sustainable and renewable resource. It’s known for its excellent water retention properties and is often used with other substrates.

Cons: On its own, coco coir might lack the necessary nutrients for some mushroom species, so it’s best used as a supplement.


Pros: Manure, especially horse manure, is a nutrient-rich substrate favoured by many gourmet and medicinal mushrooms. It’s packed with organic matter that mushrooms love.

Cons: Ensuring the manure is well-composted and free from pesticides or other harmful chemicals is essential. Fresh manure can also introduce unwanted microbes.

Humidity plays a crucial role in mushroom development. Just as plants need the right amount of water to grow, mushrooms require a specific humidity range to thrive. This moisture in the air aids in the development of the mycelium, the vegetative part of the fungus, and ensures that the fruiting bodies, or the mushrooms we see and eat, develop properly. Let’s delve into the nuances of humidity in mushroom cultivation:

RH% For Oyster Mushrooms:

Ideal Humidity Range:

Oyster mushrooms prefer a humidity level between 75% to 95%.

Why It Matters:

This high humidity ensures that the oyster mushrooms remain moist and prevents them from drying out. A consistent humidity within this range will lead to plump, juicy oyster mushrooms with a delightful texture.

Rh% for Lion’s Mane:

Ideal Humidity Range:

Lion’s Mane mushrooms thrive in a slightly higher humidity than oyster mushrooms, usually between 85% and 95%.

Why It Matters:

Lion’s Mane requires a reasonably moist environment; it’s not as forgiving as oyster mushrooms but not difficult to grow. A humidity tent with airflow holes will ensure a proper humidity range for growing Lion’s Mane. Higher humidity leads to long, spiky tendrils, giving Lion’s Mane a unique appearance and texture.

Your Guide to growing mushrooms indoors

Challenges: Some areas of the home might not naturally maintain the high humidity levels mushrooms crave. Air conditioning, heating, and general airflow can affect indoor humidity.


To cultivate mushrooms in your home with a growing kit, find an area that’s away from heating/cooling vents and ceiling fans. Keep your kits away from open windows and drafts. A humidity tent might also be helpful, but only in specific scenarios.

Why It’s Worth It:

Growing mushrooms in your house is a delightful experience. You get to witness the beauty of mushroom growth and have fresh mushrooms at your fingertips, ready to be harvested and enjoyed.

lighting guide

mushroom grow lights 6500k

While mushrooms aren’t photosynthetic like plants, light still plays a pivotal role in their growth and development. Unlike plants that require light for energy, mushrooms use light to signal growth direction and initiate the fruiting process.

Color Temperature – 6500K:

What It Means:

The colour temperature of a light source is measured in Kelvins (K). A colour temperature of 6500K is often called “daylight” because it closely mimics the natural light of a clear day.

Why It’s Ideal:

For mushroom cultivation, a 6500K light provides a spectrum that closely resembles natural daylight. This spectrum encourages healthy mushroom growth and ensures that the mushrooms grow upwards and develop properly.

Ambient Light vs. Direct Sunlight:

Ambient Light:

Mushrooms thrive in ambient light, meaning they prefer an indirect, soft glow to the sun’s harsh rays. This can be the light that filters through a curtain or the diffused light in a shaded area.

Avoiding Direct Sunlight:

Direct sunlight can dry out mushrooms and their substrate, hindering their growth. It’s essential to ensure that while mushrooms receive light, they are shielded from direct sun exposure.

Growing Mushrooms at Home:


When growing mushrooms at home, choose a location that receives plenty of ambient light but is away from direct sunlight, such as a countertop away from a window or a shaded corner.

Artificial Lighting:

If natural light is limited, consider using LED or fluorescent lamps with a colour temperature of 6500K. These can be set on a timer to mimic a natural day-night cycle, providing your mushrooms with the light they need without overexposing them.

fresh air exchange (fae)

shutterstock 1168444189

Mushrooms, like all living organisms, require a balance of essential elements to thrive. One of these critical elements is fresh air, specifically the exchange of oxygen and carbon dioxide, commonly referred to as Fresh Air Exchange (FAE). Let’s dive deeper into the significance of FAE in mushroom cultivation:

Why FAE is Important:

Oxygen Intake:

Mushrooms consume oxygen for their metabolic processes. A steady supply of fresh oxygen ensures that the mycelium, the vegetative part of the fungus, remains healthy and vigorous.

Carbon Dioxide (CO2) Removal:

As mushrooms grow, they release CO2 as a byproduct. High levels of CO2 can hinder mushroom growth, leading to elongated stems and small caps. FAE helps in reducing CO2 concentrations, promoting proper mushroom development.

Mushrooms Growing in Open Environments:

Natural FAE:

Most homes naturally have a good amount of FAE due to regular activities like opening doors and windows and the general movement of air. In such environments, ensuring adequate FAE is less of a concern.

Humidity Concerns:

While open environments provide ample FAE, maintaining humidity levels can be challenging. Monitoring and adjusting humidity is essential to prevent the substrate from drying out.

Using a Humidity Tent or Growing Tent:

Balancing FAE and Humidity: Proper FAE is crucial in enclosed environments like humidity or growing tents. These environments can trap CO2, leading to suboptimal growth conditions. At the same time, they help in maintaining high humidity levels.

Achieving Optimal FAE:

Cutting Holes: One method to increase FAE in a humidity tent is by cutting holes, allowing for passive airflow. This method also helps in maintaining humidity levels.

Removing the Tent: Another approach is to remove the tent for an hour or two each day. This action provides fresh air, ensuring the mushrooms receive the oxygen they need.

Exhaust Fans: For those using grow tents, installing an exhaust fan that pulls air to the outside is ideal. This setup ensures a constant fresh air flow, effectively managing CO2 levels.

Detriments of High CO2:

Stunted Growth:

Elevated CO2 levels can result in stunted mushroom growth, with the mushrooms producing long, thin stems and underdeveloped caps.

Poor Fruiting:

High CO2 concentrations can also delay or inhibit the fruiting process, reducing yields.

2. The Life Cycle Of Fungi

Unlike plants that grow from seeds, mushrooms develop from tiny spores, undergoing a series of stages before maturing into the fruiting bodies we recognize and enjoy. Let’s journey through the life cycle of a mushroom, from its humble beginnings as a spore to its triumphant return to the same stage:

Spore Formation:


Spores are the microscopic “seeds” of the fungal world. They form on mature mushrooms’ gills, pores, or other spore-producing structures.


Once mature, these spores are released into the environment, carried by wind, water, or other agents. Each spore is incredibly tiny and has the potential to give rise to a new mushroom.

Germination and Mycelium Growth:


When a spore lands in a suitable environment with the right conditions, it germinates, giving rise to a tiny thread-like structure called a hypha.

Network Formation:

As the hypha grows and branches out, it forms a dense network called mycelium. This mycelium is the vegetative part of the fungus, working behind the scenes, breaking down organic matter and absorbing nutrients.



When the mycelium encounters specific environmental cues, such as a change in temperature, humidity, or light, it begins the fruiting process.


The mycelium aggregates and differentiates to form a primordium, the precursor to the mushroom. As it grows and develops, it takes on the familiar shape of a mushroom cap, stem, and other structures.


The mature mushroom is the reproductive structure of the fungus. At this stage, spore-producing systems, like gills or pores, develop and become ready for spore formation.

Return to Spore:


Once the mushroom reaches maturity, it begins the process of spore production and release, completing the life cycle and ensuring the continuation of the species.

3. Guide To Set Up A Mushroom Kit

mushroom grow kit guide

Open The Window On Your Mushroom Box

Remove the perforated window on the back of your mushroom growing kit using a knife or scissors.

Make The “X” Cut To Initiate Pinning

Once the grow window is open, it’s time to make an “X” cut into the plastic of the grow block. Your cut should be 2-3 inches long.

Don’t be afraid to cut into the growing medium a little. Disturbing it slightly will encourage mushroom growth at the cut.

Even though it’s tempting, don’t make the cut too big (2-3 inches max.), or your mushroom growing kit will evaporate water too quickly, which can negatively affect your yields.

cutting open grow kit

Spray, Spray, Spray!

Next, fill the spray bottle with your grow kit with tap or filtered water.

Spray the “X” cut area well. You can fold back the flaps and get some water on the substrate, but make sure to fold the flaps back afterwards.

Keep Spraying daily!

For 2-3 weeks, you will want to spray your grow kit like this twice daily. Once in the morning and at night is sufficient, but doing it more often can improve your final yield.

Dial It Back the water

In a few weeks, you should see baby mushrooms (known as primordia or pins) forming near the “X” cut you made earlier.

Now, you want to dial back the spraying because mushrooms don’t like direct contact with water. It’s okay if they get wet, so don’t avoid it altogether, but too much spraying can cause them to dry out prematurely.

Keep Humidity High

Mushrooms absorb water through humidity in the air, not the growing medium. So keep spraying your mushrooms, but focus on getting the box wet and the area around the mushrooms.

The water will evaporate, and your mushrooms will be happy because they prefer the water vapour.

You can spray actual mushrooms themselves once a day, but avoid overdoing it, or they can dry out before being ready to harvest.

HUMIDITY TIP: Keep a bowl of water near your mushroom kit. The mushrooms will passively absorb the evaporating water as they grow.

Humidity Tents: Should I Use One?

If you purchased a Lion’s Mane Mushroom Grow Kit, you will notice that inside the box is a plastic tent with some holes. This is your humidity tent and should be used only when growing lion’s mane mushrooms.

It would be best not to spray your lion’s mane mushrooms with water directly. Instead, spray water inside your humidity tent and place it over your mushroom kit.

Doing this will increase the relative humidity around your mushrooms, and they will absorb that water as they grow. Remove the humidity tent 2-3 times daily and spray the inside with water before placing it back over your kit.

For Oyster Mushrooms

Oyster mushrooms need more airflow to grow properly, so a humidity tent isn’t the best option. If you still want to use one, you can, but be careful and only leave the tent over your kit for a few hours per day.

5. when to harvest

Mastering the art of mushroom growing doesn’t end with watching them grow; it’s also about knowing the perfect moment to harvest. In this section, we’ll guide you through the subtle cues and signs that indicate when your mushrooms are at their peak.

when to harvest oyster mushrooms infographic scaled

harvesting tips: oyster & chestnut mushrooms

Mushroom cultivation is a rewarding journey, and harvesting them at the right time is crucial to enjoying their optimal flavour, texture, and appearance. Certain signs indicate they’re ready for picking, especially for varieties like Oyster Mushrooms and Chestnuts. Let’s delve into these indicators:

Caps Turning Upwards:

As mushrooms mature, their caps begin to uncurl and turn upwards. This is often the first sign that they’re approaching the ideal harvest time. A slightly upward-turned cap indicates they’re at their peak for both Oyster and Chestnut varieties.

Wavy Edges: 

When the edges of the mushroom caps start to get wavy or frilly, they hint that they might soon be past their prime. Harvesting just before or as soon as you notice this can ensure you get them at their freshest.


Any noticeable colour change, significant darkening, lightening or spots suggests that the mushroom is aging. Harvesting before any significant discoloration is best to enjoy the mushroom’s natural flavour and appearance.


A firm yet slightly tender texture is ideal. If the mushrooms feel too soft or become slimy, they might be overripe. Always aim to harvest when they’re firm to the touch, ensuring the best texture and taste.

Spore Cycle:

Mushrooms release spores as they mature. If you notice a fine, powdery substance beneath the mushroom caps, it indicates that they’re in their spore-releasing phase. While they’re still edible at this stage, harvesting just before

harvesting tips: lion's mane mushrooms

Lion’s Mane is a unique and visually striking mushroom known for its cascading tendrils and potential cognitive benefits. Harvesting it at the right time ensures you capture its optimal flavour, texture, and nutritional value. Here are some key indicators to guide you:


Lion’s Mane, when fresh and at its peak, has a pristine white appearance. As it ages or surpasses its prime, it will begin to yellow. Monitoring its colour and harvest before significant yellowing occurs is essential to enjoy its natural flavour and benefits.


One of the distinguishing features of a Lion’s Mane is its spines or hairs. These hairs will form and elongate on the mushroom’s surface in a high-humidity environment. When these hairs reach a length of 1/4 to 1/2 inch, it’s an ideal time to harvest. These hairs indicate maturity and contribute to the mushroom’s unique texture and appearance.


A fresh Lion’s Mane mushroom will have a soft yet firm texture. As it matures, it might become slightly spongier. It’s best to harvest when the mushroom still retains some firmness to the touch, ensuring the best culinary experience.

Spore Cycle:

Like other mushrooms, Lion’s Mane will go through a spore-releasing phase. While it’s still edible during this stage, harvesting just before the spore release ensures you get the mushroom at its flavorful and nutritional peak.

6. Getting more harvests from a mushroom block

Mushroom cultivation is a gift that keeps on giving. While many assume that a mushroom grow kit is a one-time-use product, in reality, you can coax multiple harvests from a single kit with the proper care and techniques. It’s not uncommon for dedicated cultivators to achieve a 2nd, 3rd, or even 4th fruiting from a single block, maximizing their yield and enjoying the fruits of their labour multiple times over. Let’s explore the steps to achieve these additional harvests.

Resting Period:

After your initial harvest, the mycelium in your grow kit has expended significant energy-producing mushrooms. Before initiating a second fruiting, it’s essential to give your kit a resting period. Allow the kit to rest for about one week. This pause allows the mycelium to recuperate and gather energy for the next fruiting cycle.

Soaking Method:

One of the keys to initiating a new fruiting cycle is ensuring the substrate is adequately hydrated. After resting, submerge your grow kit underwater for 12-24 hours. This soaking allows the substrate to absorb the necessary moisture, preparing it for another round of fruiting. Ensure the mushroom kit is fully submerged, and after the soak, drain any excess water before placing it back in its growing environment.

Spraying Method:

If you prefer not to soak the kit or are aiming for subsequent harvests beyond the second, the spraying method is an alternative. Instead of a full soak, you’ll hydrate the growing medium by spraying it more heavily than usual. Use 50-100ml of water daily for 3-5 days. This method ensures the substrate absorbs the necessary moisture over an extended period. After this intensive hydration phase, continue your regular spraying routine to maintain the proper moisture levels.

7. Advanced Mushroom Growing Techniques

Mushroom cultivation goes beyond the basics. For those eager to delve deeper, there’s a realm of advanced techniques that can optimize and elevate your cultivation experience. Developed by seasoned cultivators, these methods promise enhanced yields and unique outcomes. This section introduces you to these refined approaches, perfect for enthusiasts ready to up their mycology game.


Mushroom cultivation often requires specific environmental conditions to achieve optimal growth. One such tool to help regulate these conditions is the humidity tent. Here’s how to use it effectively for different mushroom varieties:

for Growing Lion’s Mane:

Lion’s Mane mushrooms thrive in high-humidity environments. A humidity tent, like the one provided in the Nature Lion Lion’s Mane kit, can be beneficial to cater to this preference. This tent, a plastic bag with Fresh Air Exchange (FAE) holes, helps maintain the desired moisture levels around your mushrooms.

How to Use A Humidity Tent For Lion’s Mane Mushrooms:

Place the provided tent over your growing block. Instead of spraying the mushrooms directly, mist the inside of the tent to create water droplets. This method ensures a humid environment without wetting the mushrooms, which can be counterproductive. However, it’s crucial to remember that while the tent aids in maintaining humidity, it can restrict airflow. To counter this, remove the tent at least once daily for an hour or two, allowing the mushrooms to breathe. Neglecting this step can lead to stunted growth or other cultivation issues due to reduced oxygen levels.

for Growing OYSTERS and CHESTNUTS:

While using a humidity tent for Oyster and Chestnut mushrooms isn’t typically recommended due to their preference for ample airflow, it can be beneficial when used judiciously. If you choose a tent for these varieties, the approach should be the opposite for Lion’s Mane. Instead of keeping the tent on continuously, place it over the mushrooms for just 1-2 hours daily. This brief period can enhance the water uptake, potentially boosting yields. However, be cautious. Extended tent usage can hinder these mushrooms, as they prioritize airflow. Restricting this can lead to growth issues or suboptimal results.


Taking your mushroom cultivation to the next level involves expanding your grow space, and one effective method is utilizing 5-gallon buckets. This approach allows cultivators to maximize yield from a single mushroom kit, spreading the mycelium across multiple containers and reaping the benefits of larger, more abundant harvests.


🪣 5-gallon Bucket with Lid: The primary container for your expanded grow.

🌾 Chopped Wheat Straw: Acts as the substrate for mushroom growth.

🛌 Pillow Case: Useful for pasteurizing the straw.

🍲 Pot: To boil and pasteurize the straw.

🔩 Drill & 1/2″ Drill Bit: To create bucket ventilation holes.

Substrate: Straw is a favoured choice for many cultivators due to its ease of pasteurization and lower contamination rates. Its fibrous nature provides ample space for mycelium to grow and spread, leading to robust mushroom development.

Pasteurize: Boiling the chopped straw inside a pillowcase for two hours effectively pasteurizes it. After boiling, drain any excess water, preparing the straw for inoculation.

Prepare the Bucket: Using your drill and the 1/2″ bit, create 10-15 evenly spaced holes around the sides of the bucket. These will serve as ventilation points and fruiting sites.

Sanitation: A clean environment is paramount. Minimize airflow by turning off fans and furnaces and closing windows. Ensure the area is spotless, wear freshly laundered clothes, shower, and maintain hand hygiene throughout the inoculation process.

Inoculation: It’s time to inoculate once the straw cools to 35C. Begin by layering about 8 inches of straw at the bucket’s base. Break up the contents of a Nature Lion grow kit, spread a portion of the mycelium over the straw, and repeat the layering process until the bucket is full. Seal with the lid once filled.

Colonization: Patience is vital. Allow 3-6 weeks for the mycelium to colonize the bucket. During this phase, maintain a temperature range of 18C to 22C.

Fruiting: Upon complete colonization, mushrooms start to pin from the drilled holes. This signals the onset of the fruiting stage. Maintain appropriate fruiting conditions and watch as your mushrooms flourish.


📈 Increased Yield: More space means more mushrooms.

💰 Cost-Effective: Utilize one kit for multiple buckets.

🔄 Sustainability: Buckets are reusable for multiple grows.

🌱 Natural Environment: Straw mimics mushrooms’ natural growth medium.

🧪 Experimentation: Allows for trying different mushroom varieties.

C) OUTDOOR Mushroom Plots

Growing mushrooms outdoors offers a unique opportunity to integrate mycology with natural environments. Whether using logs or wood chip beds, the great outdoors can be an ideal setting for certain mushroom varieties. Here’s how to get started:

Making Mushroom Logs For Growing Outdoors:

Select a Log: Choose freshly cut hardwood logs, ideally oak or maple, about 3-5 feet long and 4-8 inches in diameter.

Drill Holes: Using a drill, create holes about 1 inch deep and spaced 6 inches apart in a diamond pattern along the log.

Inoculate: Take a Nature Lion mushroom kit and break up the contents. Use the mycelium to fill each drilled hole.

Seal: Cover each inoculated hole with wax to protect the mycelium from contaminants and retain moisture.

Position: Place the logs in a shaded area, preferably under a canopy of trees or a makeshift shade.

Maintain: Moisten the logs by spraying them with water during dry periods. Avoid letting them dry out completely.

Wait: Over several months, the mycelium will colonize the log. Once fully occupied, the log will start fruiting, producing fresh mushrooms.

Wood Chip Beds:

Growing mushrooms in wood chip beds are excellent for certain varieties that thrive in such environments.

Materials: You’ll need fresh wood chips, preferably from hardwood trees, and a Nature Lion mushroom kit for inoculation.

Environment: Choose a shaded location in your garden or yard. The area should be well-draining and protected from strong winds.

Preparation: Lay down a layer of cardboard on the chosen spot. This acts as a barrier against weeds. Over this, spread a 4-6 inch layer of fresh wood chips.

Inoculation: Break up the contents of your Nature Lion mushroom kit and mix it evenly with the wood chips.

Maintenance: Keep the wood chip bed moist, especially during dry spells. Regular watering ensures the mycelium remains active and healthy.

Types of Mushrooms: Varieties like Wine Cap (Stropharia rugosoannulata) and certain types of Oyster mushrooms are particularly well-suited for wood chip beds.


When it comes to mushroom cultivation, the way you open your mushroom bag can significantly influence the growth and yield of your fungi. Depending on the mushroom variety and your cultivation goals, you might opt for top-fruiting or side-fruiting methods. The size and type of opening can also affect the appearance, size, and number of mushrooms you harvest.

Traditional “X” Cut:

One of the most common methods is the “X” cut made on the side of the bag. For varieties like Oysters and Chestnut, an optimal cut ranges from 2-4 inches across. A larger “X” might lead to a higher number of mushrooms, but they could be smaller in size. Conversely, a smaller cut could yield fewer but larger mushrooms. For Lion’s Mane, a more delicate approach is advised. A smaller “X”, about 1-2 inches across, is ideal. This size ensures that the Lion’s Mane grows uniformly, reduces substrate on the fruiting body, and simplifies the harvesting process.

Poking Holes:

Commercial farms often employ another technique: poking holes into the mycelium blocks. These holes, ranging from 1/2″ to 1″ in diameter, serve as fruiting points. While this method is effective, it might lead to a slightly extended waiting period before the appearance of mushroom pins. The reason lies in oxygen availability. A smaller hole offers less oxygen to the substrate compared to a larger opening. Since oxygen is a primary trigger for mushroom growth from mycelium, this can slightly delay the fruiting process.

E) advanced misting

When diving into the intricate world of mushroom growing techniques, one that stands out as paramount is misting. Properly misting your mushroom substrate can significantly influence your yield, ensuring your mushrooms grow to their fullest potential. Let’s delve into the art and science of advanced misting.

Initial Phase: The Heavy Mist

You’re embarking on a transformative journey once you cut open your mushroom grow kit. In these initial days, your substrate needs ample moisture. Aim to mist heavily, using approximately 15-30ml of water. This consistent, generous misting should be maintained for the first 3-4 days. You might need to mix up to three times daily, especially initially.

Distance Matters

Remember that distance is critical when aiming your spray bottle at the substrate. Position the bottle 12-18″ away from the growing medium. Think of it as a gentle rain shower for your mushrooms. Aggressive spraying risks damaging the delicate mycelium. Opt for a refined, gentle mist from a distance. It’s a more advanced technique that ensures your mushrooms get the moisture they need without causing harm.

X Marks the Spot

You’ll find four flaps after cutting an X shape into the mushroom bag. Lift these flaps gently and administer a fine mist onto the substrate. The goal is a delicate balance: you want the substrate wet but not drenched. Remember, a subtle touch goes a long way. It’s far better to spray less water more frequently than to drown the mycelium in enthusiasm.

Maintenance Phase: Keeping Up the Humidity

As days progress, you’re not looking to flood the mushrooms but maintain the surface-level humidity. Once your mushrooms grow, transition to misting 1-2 times per day using about 10-20ml of water. And while it’s okay for the mushrooms to get a little wet occasionally, that isn’t your primary aim. Mushrooms absorb water from the air, so as you mist around them, and as that water evaporates, they’ll take in the moisture they need to flourish.

Pro Tip: A Bowl of Bounty

Consider placing a water bowl near your mushrooms can be a game-changer. This simple act can significantly increase humidity in the environment, potentially leading to richer yields. It’s a small step with a significant impact.

f) long term storage

Mushroom kits, like all fresh products, come with a shelf life. Specifically, our kits are optimized for a period of 2 months. Naturally, for best results, it’s recommended to commence your mushroom growing journey as soon as you receive your kit. Yet, life happens, and sometimes you need to delay that journey.

Understanding the Filter Patch

Each mushroom kit bag is thoughtfully equipped with a filter patch. This isn’t just a decorative feature. This patch plays a pivotal role in allowing CO2 to exchange, facilitating the mycelium’s growth within the sealed environment. It’s like a tiny, breathable window for your developing fungi.

Refrigerating a Fully Colonized Block

Should you notice that your block is bursting with white, fully colonized mycelium and you’re not ready to grow just yet, there’s a workaround. By simply placing some tape over the filter patch, you can effectively seal off the airflow. With this simple modification, your kit can be tucked away inside a fridge for an impressive duration of up to 5 months. It’s essentially a little hibernation phase for your fungi.

Reacclimatizing After Cold Storage

Here’s a key point to remember: fungi, much like us, aren’t huge fans of abrupt climate changes. After their extended chilly vacation, give your mushrooms a cozy week at room temperature. This gentle transition time helps them acclimate, preparing them for their imminent growth phase.

In conclusion, while immediate use of the mushroom kit promises optimal results, with a little care, long-term storage can work wonders too. Whether you’re diving in now or later, your mushroom adventure awaits.

f) Moisture Content Calculator

When making your mushroom substrate, you must prepare it using the proper moisture content. To help you achieve this, I’ve added a moisture content calculator that you can use to fine-tune your substrate recipes to the right moisture percentage.

This free tool is recommended for anyone who is making their substrate blocks and needs to figure out the proper amount of water required in their final preparations.

7. common misconceptions

Mushroom cultivation, while incredibly rewarding, is riddled with myths and misconceptions. These myths can sometimes hinder budding mycologists and mushroom enthusiasts. Let’s delve into some of the most common misconceptions and set the record straight.


One of the most enduring myths is that mushrooms, being fungi, thrive only in the dark. While it’s true that they don’t rely on photosynthesis like plants, many mushroom species actually prefer some amount of ambient light. Light can act as a signal for many mushroom species, triggering them to initiate fruiting and sometimes influencing the direction in which they grow. So, no, your mushrooms don’t necessarily want to be kept in the dark!


Yes, many mushrooms thrive on dung, but that’s just a small fraction of the fungi world! There are wood-loving mushrooms, such as shiitake and oyster mushrooms, that prefer to grow on logs, wood chips, or similar substrates. Additionally, there are also insect-loving fungi, like the cordyceps, that have a unique relationship with insects. Mushrooms are incredibly diverse, and their growing preferences are a testament to that.


Contamination, the bane of every mushroom cultivator, isn’t always the end of the line. While it’s true that certain contaminations can overpower and ruin a mushroom culture, many times, mushrooms can still grow despite some contamination. Experienced cultivators often learn techniques to rescue a batch or to cut away and isolate the healthy portion from the contaminated area. It’s not always a lost cause!


Starting a mushroom culture from spores is just one of the many ways. In fact, many cultivators work with tissue cultures of known mushroom varieties. These tissue cultures, often grown on agar or grain, are taken from a part of a mature mushroom and can be a more predictable way to grow certain mushroom strains. It’s not always about the spores!


When people say they dislike mushrooms, they often cite texture as the primary reason. However, mushrooms are incredibly varied in texture, and different cooking techniques can significantly alter their mouthfeel. For instance, shiitake mushrooms can be chewy when sautéed but crispy when baked. Oyster mushrooms can be tender and delicate, while portobellos can be meaty. Exploring different mushroom varieties and cooking methods can completely transform your mushroom experience.
