Mushroom Bag Fruiting: Timing For Success

Mushroom cultivation is a delicate process that requires careful observation and understanding of the various stages of development. The use of mushroom grow bags has revolutionized the way both professionals and enthusiasts approach mushroom growing. The bags are designed to support the growth and development of mushrooms of various species and offer a convenient and efficient way to embark on your mushroom-growing journey. The timing of when to fruit a mushroom bag is crucial as it can impact both the quantity and quality of the yield.

Optimal conditions: temperature, humidity, light, and fresh air

Optimal conditions are critical to the success of mushroom cultivation. Here are the ideal conditions for temperature, humidity, light, and fresh air:

Temperature

The temperature requirements vary depending on the mushroom variety. For instance, oyster mushrooms thrive in a temperature range of 75-85°F (24-29°C) during colonization, while shiitake mushrooms prefer slightly cooler temperatures of 72-78°F (22-25°C). Button mushrooms fall somewhere in between, with an ideal temperature range of 70-75°F (21-24°C). Maintaining a steady temperature throughout the growing area is crucial, and deviations from the optimal range can impact the success of the crop.

Humidity

Humidity plays a vital role in mushroom cultivation, influencing their growth and development. To maintain the ideal humidity levels, growers can employ techniques such as using misting spray bottles, pond misters, or humidifiers. Regular misting of the mushrooms and the surrounding area with a spray bottle can help maintain the desired humidity. Additionally, good air circulation is essential for optimal humidity levels, and this can be achieved through the use of fans or by opening windows and doors.

Light

Mushrooms typically require specific light durations, or photoperiods, for optimal growth. Most mushrooms benefit from 12-16 hours of light per day, followed by a consistent dark period for rest. During the mycelial growth stage, blue light is necessary to promote healthy mycelium development, while red light is crucial during the fruiting stage to stimulate fruiting body formation. Full-spectrum LED lights or HPS lights are ideal for providing the necessary red light wavelengths during the fruiting stage.

Fresh Air

Fresh air exchange is crucial in mushroom cultivation to regulate carbon dioxide levels. Excessively high carbon dioxide levels can hinder mycelium growth and fruit development. Integrating a fresh air exchange fan into the growing environment helps maintain oxygen levels, removes stale air, and prevents the buildup of harmful gases. A mushroom exhaust fan is also beneficial for removing excess humidity and carbon dioxide, aiding in controlling moisture levels and preventing mould or bacterial growth.

Contamination risks: sterilise equipment and environment

Mushroom growing is a delicate process that requires a sterile environment and careful technique to avoid contamination. The first step in preventing contamination is to understand the common sources of contaminants and take steps to mitigate these risks.

Common Contaminants

Moulds, such as white, blue-green, or orange bread mould, are common contaminants that can affect the growing medium or substrate. Insects, such as flies or mites, can also be a source of contamination. Other common contaminants include Trichoderma, which can be difficult to control once it spreads, and Bacillus, a bacterial contaminant that can go undetected due to its slimy, grey appearance.

Sterilising Equipment

To prevent contamination, it is crucial to use sterilised equipment and tools. Sterile grain jars, fruiting blocks, and agar dishes should be exposed for a minimal amount of time during the inoculation process. Scalpels and blades used for culture transfers must be flame-sterilised between each transfer until they are red hot. Rubbing alcohol is essential for wiping down tools, surfaces, grow bags, grain jars, and agar plates before use.

Sterile Environment

In addition to sterilising equipment, it is vital to maintain a clean and sterile work environment. This includes ensuring proper ventilation and air circulation to prevent the buildup of CO2 and the growth of mould. Humidity levels should be monitored and kept between 85-95% to prevent stunted growth or increased contamination risk. A cleanroom environment can be implemented to control the concentration of airborne particles. Workers should also be trained in proper hygiene practices, including handwashing and glove use, to prevent the spread of germs to the mushrooms.

Substrate Sterilisation

The substrate plays a crucial role in mushroom growing and must be properly sterilised before inoculation. Bulk substrates and grains naturally contain competing organisms and dormant spores that need to be eliminated through sterilisation. This can be achieved by subjecting the substrate to high pressure and temperature for an extended period using a stovetop pressure canner. For grain sterilisation, grains can be soaked for 12-24 hours, dried, and then sterilised at 121 degrees Celsius for at least 2 hours and 30 minutes using a pressure cooker or autoclave.

Indicators of readiness: size, veil state, and strain characteristics

When it comes to determining the optimal time to fruit a mushroom bag, several key indicators of readiness come into play, including the size of the mushrooms, the state of the veil, and the specific strain characteristics. Here's a detailed overview of each of these factors:

Size is an important indicator of mushroom maturity and readiness for fruiting. Depending on the strain, mushrooms can range in size from tiny to large. As a general rule, mushrooms are ready for harvesting when their

Harvesting: timing, gloves, and sterile environment

Harvesting mushrooms is a straightforward process, but getting the timing right is crucial to maximising future flushes and getting the most out of your efforts. The general rule is that it is better to harvest too soon than too late. Harvesting too late can ruin the whole grow, whereas harvesting too early may result in a smaller yield, but you will still be able to salvage your crop.

The ideal time to harvest mushrooms is just before the veil tears. The veil is located on the underside of the cap and covers the gills. On a juvenile mushroom, veils are usually grey-white and fleshy. As the mushroom matures, the veil will darken and begin to sag before tearing. Once the veil tears, the mushroom will continue to grow in size but will not develop any more psilocybin or psilocin, which means that it will be less potent as a percentage of its overall weight. Therefore, it is important to keep a close eye on the veils of your mushrooms and harvest them as soon as you notice any signs of darkening.

While harvesting, it is recommended to wear gloves to prevent any contamination from your hands coming into contact with the mushrooms. However, some people choose not to wear gloves and simply ensure that their hands are clean before handling the mushrooms. Ultimately, the decision to wear gloves or not is a matter of personal preference.

Creating a sterile environment is crucial when growing mushrooms from scratch. While it is nearly impossible to achieve perfect sterility, taking extra steps to minimise contamination is important. This includes properly sterilising and pasteurising the bulk substrate and grains, which naturally contain competing organisms and dormant spores that can outcompete your mushrooms if not adequately reduced or eliminated. High pressure and temperature for extended periods are effective methods to sterilise the substrate. Additionally, the tools, hands, and clothing of the cultivator can also be sources of contamination, so it is important to maintain cleanliness throughout the process.
