Mushroom cultivation is a lucrative business that can be started with minimal equipment and investment. The size and location of the farm, the variety of mushrooms grown, diseases, management, advertising, marketing, and years in the industry are some of the factors that affect profit margins. To increase mushroom size, protein-rich supplements such as cottonseed meal, soybean meal, and feather meal can be added during spawning or after spawning before casing. Additionally, the environmental factors that affect mushroom height, diameter, and cap size are air temperature, humidity, fresh air, and compact material. Higher inoculation rates can also increase the speed of mycelium growth, and growers can experiment with different substrates and preparation methods to increase yield and speed of colonization.

Choose fruits that grow quickly and are the size you want, then clone them
Mushrooms are the fruiting bodies of harmless fungi that are beneficial to the overall micro-ecosystem. To increase the size of your mushrooms, choose fruits that grow quickly and are the desired size, and then clone them. This process involves selecting the largest mushrooms from your harvest and using them as the basis for your next crop. Here's a step-by-step guide:
Firstly, select the biggest mushrooms from your current crop. Cut a piece from towards the base of the mushroom and transfer it to an agar medium. Repeat this process a few times to ensure you have a strong culture. This technique is known as cloning, and it allows you to isolate the genetics of the largest mushrooms and encourage faster colonization and larger yields in subsequent crops.
Once you have a healthy culture on your agar, transfer it to a grain medium. From this batch, you can again select the largest mushrooms and repeat the cloning process. This iterative approach helps to consistently increase the size of your mushrooms with each new crop.
While cloning is a useful technique, it's important to remember that mushroom growth is influenced by various factors, including temperature, oxygen and humidity levels, and the species of mushroom. Additionally, the growth process can be unpredictable, and contamination can sometimes occur. Therefore, it's essential to be patient and adaptable when cultivating mushrooms and to create an environment that supports healthy mushroom growth.
To create optimal conditions for your cloned mushrooms, maintain a temperature range of 70 to 76 degrees Fahrenheit, which is typically considered room temperature. Ensure that your mushrooms receive 4 to 6 hours of indirect light per day, using a low-wattage light if necessary. Additionally, provide fresh air to the fruiting chamber by removing the lid once a day or every other day and fanning the cakes to reduce carbon dioxide buildup.
By choosing fruits that grow quickly and are the desired size, cloning them, and creating optimal environmental conditions, you can increase the size of your mushroom crop. Remember to be patient and persistent, as mushroom growing can sometimes involve unexpected challenges and curveballs.

Increase CO2 and oxygen levels during the early pin/fruiting stages
Increasing CO2 and oxygen levels during the early pin/fruiting stages can have a significant impact on mushroom size. This technique is particularly beneficial for species that are sensitive to carbon dioxide levels, such as oysters, shiitakes, and lion's mane. Here are some detailed instructions to help you achieve this:
Firstly, it's important to understand the role of CO2 and oxygen in mushroom growth. Carbon dioxide is essential for mushroom respiration, and higher levels during the early stages of fruiting can lead to larger mushrooms. Additionally, adequate oxygen levels are critical for mushroom metabolism and cell division, influencing the size and health of the mushrooms.
To increase CO2 levels, one effective method is to use a CO2 generator. These devices burn propane or natural gas to produce CO2, which can then be released into the growing area. Ensure you carefully follow the safety instructions provided with the generator, as improper use may be hazardous. Alternatively, you can use a fermentation method by mixing one part sugar (such as cane sugar or molasses) with four parts warm water and activating the mixture with yeast. Place the solution in a container with an airlock, allowing CO2 to escape into the growing area while preventing contaminants from entering.
Another natural approach is to introduce plants into your growing space. During the daytime, plants release oxygen through photosynthesis, increasing oxygen levels. At night, they consume oxygen and release CO2, helping to maintain optimal CO2 levels for mushroom growth.
Additionally, you can manipulate oxygen and CO2 levels through proper ventilation. During the early pin/fruiting stages, ensure there is adequate airflow in your growing area. Use fans to circulate air, and consider installing an air exchange system to bring in fresh air and remove stale air. Aim for a gentle breeze, as strong airflow can dry out the growing medium and impact mushroom development.
Monitoring CO2 and oxygen levels is crucial to ensure they remain within the optimal range. You can purchase affordable CO2 meters to track levels and make adjustments as needed. The ideal CO2 level during the early pin/fruiting stages is typically between 1200-1500 ppm (parts per million), but some species may prefer levels up to 5000 ppm. Maintain a relatively higher humidity level of around 80-90% during the pinning stage, gradually decreasing it to 60-70% during the fruiting stage.
By implementing these techniques, you can effectively increase CO2 and oxygen levels during the early stages of mushroom growth, leading to larger and healthier mushrooms. Remember to adapt these methods based on the specific mushroom species you are cultivating and always practice good sterilization and contamination prevention techniques for successful mushroom cultivation.

Use protein-rich supplements such as cottonseed meal and soybean meal
The use of protein-rich supplements is a well-known method to increase mushroom size. Cottonseed meal and soybean meal are two such supplements that can be used to achieve this. These supplements provide the mushrooms with the necessary nutrients to support their growth and development.
Cottonseed meal is a good source of protein and other essential nutrients that mushrooms need to thrive. It is often used as a supplement for animal feed and has been found to be effective in increasing mushroom production as well. By using cottonseed meal, growers can provide their mushrooms with a boost of protein and other beneficial compounds that promote larger and healthier mushrooms.
Soybean meal is another effective protein-rich supplement for increasing mushroom size. It is a by-product of soybean transformation and is rich in nitrogen and other essential amino acids. Soybean meal has been studied extensively and has been found to have a positive impact on the cultivation of various mushroom species, including Agaricus and Pleurotus. One study by Kopytoswky-Filho et al. (2008) reported a significant increase in the production of Agaricus subrufescens when using a soybean meal-based commercial supplement.
The process of supplementation involves adding these protein-rich nutrients to the mushroom substrate, either during spawning or after spawning before casing. This provides the mycelium with a strong nutritional base, supporting its growth and resulting in larger mushrooms. Growers can choose from a variety of commercial supplements available on the market, specifically designed to enhance mushroom cultivation.
In addition to cottonseed meal and soybean meal, other organic protein sources such as cereal bran, enriched with minerals or vitamins, can also be used as supplements. These supplements not only increase mushroom size but also improve the overall yield and quality of the crop. By utilizing these protein-rich supplements, growers can optimize their mushroom cultivation practices and achieve larger, healthier, and more abundant mushrooms.

Use a high inoculation rate or amount of spawn added to the substrate
Inoculation is the process of adding mushroom spores or spawn to a suitable growth medium. The inoculation rate is the amount of mushroom spawn or liquid culture added to a substrate. This rate is usually shown as a ratio to the amount of substrate. The substrate is any material that is a food source for mushroom mycelium. The inoculation rate for mushroom spawn is a balance between the speed of spawn colonisation and the cost of spawn per pound or kilogram of mushroom yield. The higher the spawn rate, the faster the mycelium will colonise the substrate. However, a higher inoculation rate does not typically produce a larger amount of mushrooms and will increase costs.
For new cultivators, a high inoculation rate can increase the chances of success. As cultivators become more experienced, they can lower the inoculation rate and observe the difference in colonisation time. Different substrates require different spawn rates, so it is important to research the specific substrate being used. The type of mushroom being grown also affects the inoculation rate, with fussier and slower-colonising species requiring more spawn.
The process of mushroom inoculation begins with substrate preparation. This includes ensuring optimal moisture content, cleaning the substrate of contaminants, mixing substrates, and sometimes placing the substrate into a bag. The substrate temperature should also be checked, especially if it has been sterilised, to ensure it has cooled to room temperature so as not to kill the mycelium. Sterility is critical when using high-nitrogen materials like agar, grain, and supplemented sawdust, which are more susceptible to ambient microorganisms.
There are two common methods of spawn distribution: "top spawning" and "through spawning". Top spawning involves placing the spawn on top of the substrate and allowing it to grow down, while through spawning involves distributing the spawn throughout the substrate.

Provide mushrooms with a moist environment to grow
Mushrooms require a moist environment to grow. The moisture content of the substrate, or growing medium, is crucial for mushroom growth. Mushrooms grow from spores, and these spores need to be inoculated into a substrate such as compost, straw, sawdust, grain, straw, wood chips, or even kitty litter and cardboard boxes. The substrate provides the moisture and nutrients required for mushrooms to grow and develop.
To ensure the substrate has the correct moisture content, you can perform a squeeze test before proceeding with inoculation. The substrate should be pasteurized or sterilized to prevent competition from other organisms. During the fruiting stage, relative humidity levels should be maintained between 80-95%. This can be achieved by misting mushrooms with water twice a day, or by using a humidity tent made from a plastic bag, a humidity chamber, or a humidifier linked to a regulator.
It is important to maintain proper moisture levels throughout the cultivation process. This can be done by regularly spritzing the soil with water and covering it with a damp cloth. The moisture content should be monitored and adjusted as needed to promote healthy mushroom growth.
Additionally, the temperature of the substrate should be monitored to prevent overheating. Mushrooms grow best in warm and humid conditions, with temperatures ranging from 55-65°F (13-18°C). After the mycelium appears, the temperature can be lowered to 55-60°F (13-16°C).

Frequently asked questions
There are several methods to increase the size of mushrooms. The first is to increase the CO2 and oxygen levels in the early pin/fruiting stages. The second is to use a substrate with higher nutrient content to increase the speed of colonisation and yield. The third is to increase the spawn: bulk substrate ratio to increase nitrogen content. Lastly, protein-rich supplements such as cottonseed meal, soybean meal, and alfalfa meal can be added during spawning or after spawning before casing to increase mushroom production.
Coffee grounds are a good substrate to use as they are effectively sterilised when used to produce coffee. It is important to inoculate the same day as brewing the coffee and to add sawdust to increase aeration.
Spawn distribution impacts the speed of colonisation. The two common methods of distribution are “top spawning” and “through spawning”. Top spawning is good for inoculating full containers that cannot be shaken or for low-stakes cultivation.
The higher the inoculation rate or amount of spawn added to the substrate, the faster the mycelium will grow through the substrate. However, the substrate likely will not produce a larger amount of mushrooms, so a high inoculation rate means more money spent on spawn per pound of mushrooms.
Other factors that can increase mushroom size include air temperature, humidity, fresh air, and compact material. Additionally, in the video game Minecraft, huge mushrooms can be grown by planting them in a 7x7x8 space with a maximum height that is one block shorter than the available vertical space.
