Optimal temperature, humidity, and oxygen levels
Temperature, humidity, and oxygen levels are the three critical factors that will bring the substrate from a vegetative stage to a fruiting stage. Controlling these factors at the right time will cause the substrate to fruit. The ideal temperature, humidity, and oxygen levels for optimal mushroom growth are as follows:
Temperature
The ideal temperature for fruiting varies with the mushroom species and strain. For most mushrooms, the temperature should range between 50-70°F (10-21°C), but it can be as high as 70-75°F for some species. Dropping the temperature slightly can induce fruiting in some mushrooms.
Humidity
Most mushroom species prefer high humidity levels of 80 to 95%. Humidity levels above 85% are generally considered ideal for mushroom fruiting. However, during the dry winter months, it may be necessary to increase humidity levels using a humidifier or other methods.
Oxygen Levels
Good air exchange and oxygen circulation are crucial for mushroom growth. Providing adequate ventilation with a fan or similar method helps maintain low CO2 levels and ensures that mushrooms have access to the oxygen they need. Opening the bag or container once a day or every other day can also help provide fresh air and improve oxygen levels.

Exposure to light
Providing an adequate lighting source is essential for successful mushroom fruiting. In environments with insufficient natural light, artificial lighting can be used to supplement. For example, an LED light can be added to the inside cover of a monotub to induce fruiting. Metal Halide lights are also recommended as they provide the blue spectrum of light that mushrooms require.
The intensity and duration of light exposure can influence mushroom growth. Some sources suggest that sunlight entering a fruiting chamber during the summer months can result in significant condensation, creating an ideal environment for mushroom fruiting. However, during winter, the reduced sunlight may require the use of additional equipment, such as a humidifier, to maintain the necessary humidity levels.
It is important to note that light is not the only factor that triggers mushroom fruiting. Full colonisation of the substrate, temperature, humidity, oxygen levels, and carbon dioxide levels also play significant roles in inducing fruiting. Nevertheless, light exposure is a critical component that can influence the overall success of mushroom cultivation.

Full colonisation of the substrate
To achieve full colonisation, it is essential to maintain optimal environmental parameters, including consistent temperatures, relative humidity, oxygen circulation, and adequate lighting. Temperature plays a vital role, with the ideal range depending on the specific species being grown. For example, the temperature for inducing fruiting is typically around 70-75 degrees Fahrenheit, but it can vary between 50-70 degrees Fahrenheit (10-21 degrees Celsius) for different mushroom species.
Humidity is another critical factor, with most mushroom species preferring high humidity levels between 80 and 95%. During the colonisation process, it is important to monitor the substrate for any signs of drying out and mist it with clean or distilled water if necessary. Folding the bag shut with tape or a paper clip can help retain moisture.
Oxygen levels and air exchange are also key considerations during colonisation. Adequate oxygen circulation and proper ventilation are essential for mushroom growth. A computer fan can be used to improve air exchange and enhance the quality of the mushrooms. Additionally, exposing the substrate to light, such as indirect sunlight or LED lights, can induce fruiting, although light levels should be adjusted according to the specific species' requirements.
The full colonisation of the substrate is a critical trigger for the pinning stage, along with FAE (CO2 PPM). Allowing the substrate to colonise completely before inducing FAE can help initiate pinning within a few days. However, it is important to monitor the substrate and adjust the growing conditions as needed to ensure optimal colonisation and fruiting success.

Air exchange and CO2 levels
Air exchange and carbon dioxide (CO2) levels are critical factors in inducing fruiting in mushrooms. The mycelium colonises the substrate, but high CO2 levels prevent it from consuming the substrate entirely. During fruiting, it is essential to provide ample air exchange by removing the covers of the growing container. This increased air exchange lowers CO2 levels and is a significant trigger for the pinning stage, where mushrooms start to form.
Good air exchange can be achieved through ventilation or the use of a fan. A computer fan, for example, improves air exchange and results in higher-quality mushrooms. The fan helps to quickly reduce CO2 levels in the growing environment, ensuring that mushrooms have sufficient oxygen for optimal growth.
Small holes in the growing container, such as a plastic bin, can also facilitate air exchange. However, it is important to periodically air out the container by removing the cover to ensure that CO2 levels do not build up. The frequency of airing out the container can vary, but it is generally recommended to do so at least twice a day.
While CO2 levels are important, other factors also influence the pinning stage. Full colonisation of the substrate by the mycelium is considered a major trigger for pinning. Additionally, some sources suggest that FAE (CO2 PPM) is the primary pinning trigger, emphasising the need to maintain low CO2 levels during the colonisation phase to prevent premature fruiting.
By providing adequate ventilation, using fans to improve air circulation, and managing CO2 levels through proper container design and periodic airing out, growers can create optimal conditions for mushroom fruiting and promote healthy mushroom development.

Spawning and inoculation
Once you have prepared your bulk substrate, the spawning process can begin. This involves introducing grain spawn/mycelium into the mix. This can be done directly through an injection port using a syringe with liquid culture, via agar plates, or through the direct transfer of colonized grain spawn. After inoculation, the fungi will begin to colonize and spread throughout the medium, forming a dense network called mycelium, which supports the entire system. This process usually takes about six weeks.
To create an optimal environment for your mushrooms, you should maintain consistent temperatures, relative humidity, oxygen circulation, and adequate lighting. The ideal temperature range for most mushrooms is between 50-70°F (10-21°C), but this may vary depending on the species. Humidity levels should generally be above 85%, with most species preferring 80-95%. Light exposure varies by species, with some preferring indirect sunlight and others, like button mushrooms, favouring darkness.
During the spawning and inoculation process, it is crucial to maintain high CO2 levels. This is achieved by packing the substrate into airtight bags. As the mycelium colonizes the substrate, it is important to monitor gas exchange and adjust as needed. Providing adequate air exchange is crucial, as it triggers the pinning stage and ensures the mushrooms have enough oxygen to grow optimally.
Additionally, the substrate should be kept moist. If it appears to be drying out, mist it with clean or distilled water and fold the bag shut to hold in moisture. You may also need to open the bag once a day or every other day to provide fresh air to the substrate.

Frequently asked questions
The ideal temperature and humidity levels depend on the species of mushroom being grown. Generally, temperatures should range between 50-75°F (10-21°C), and humidity levels should be above 85%.
First, prepare the bulk substrate. Then, introduce grain spawn/mycelium into the mix using either the syringe method or agar plates. After inoculation, the fungi will spread throughout the medium, forming a dense network called mycelium. Once the mycelium has fully colonized the substrate, provide air exchange by removing covers, which will trigger the pinning stage. Finally, the mycelium will consume the substrate and produce fruit bodies, or mushrooms.
You will need a growing chamber, such as a plastic tote or monotub, with a humidity source like a humidifier or reptile fogger. Additionally, a computer fan can improve air exchange and circulation. For lighting, a simple LED light can be added to the inside cover of the monotub.
