What You'll Learn
The yield depends on the substrate
The yield of mushrooms from a syringe depends on several factors, one of the most important being the substrate used. A spore syringe is a sterile syringe filled with a liquid solution that contains mushroom spores, which are the reproductive units of fungi. When inoculated into a substrate, these spores germinate and grow into mycelium, which eventually produces mushrooms.
The type of substrate used for mushroom cultivation plays a crucial role in determining the yield. Common substrates include brown rice flour, hardwood sawdust, straw, and coffee grounds. Each substrate has its own nutritional profile, which can impact the growth rate of the mycelium and the fruiting bodies. For instance, a nutrient-rich substrate may support faster growth and higher yields compared to a less nutritious option. The bigger and deeper the substrate, the more mushrooms it will grow.
One popular method of mushroom cultivation is the Bulk Substrate Tek, which uses mycelium to grow on a larger amount of substrate, such as straw or coco coir. This technique often leads to higher yields, with up to several pounds of fresh mushrooms from a single spore syringe. Yields can range from 500-1500 grams fresh.
Another method is the Mono Tub Method, which involves using a large plastic container to create a controlled environment for fruiting. Cultivators can achieve impressive yields by optimizing humidity and airflow, often producing multiple flushes of mushrooms over time. The yield estimate for this method is around 1500-2000 fresh grams or 150-200 dry grams of mushrooms.
It is important to note that some substrates may be more prone to contamination than others. For example, coffee grounds are very prone to contamination and may not be suitable for growing certain types of mushrooms, such as Agaricus.

The type of substrate matters
The type of substrate used for mushroom cultivation plays a crucial role in determining the yield. Different types of substrates are best for various mushroom species. For example, oyster mushrooms are extremely resilient and may colonize a wide range of materials, whereas truffles prefer to grow on the roots of living trees, making them difficult to cultivate commercially.
There are several commonly used substrates by mushroom growers worldwide. One such substrate is straw, which is an inexpensive and effective option. It is available at farm shops, pet stores, and other locations that sell animal feed or bedding. Similar agricultural products, such as corn stalks, can also be used. Another option is coffee grounds, which are advantageous because the brewing process pasteurizes the grounds, allowing growers to skip the additional steps needed for other substrates. Local coffee shops will often provide used coffee grounds for free. To use coffee grounds as a substrate, combine a kilogram of espresso grounds (as filter or cafetière coffee grounds are typically too wet) with 100 grams of mushroom spawn in a blender. For improved air exchange and faster colonisation, 20% straw can be added to the mix.
Many varieties of fungi feed on dead wood, so cultivating them on cut logs is a perfect choice. Most hardwood tree species, such as beech, poplar, maple, oak, birch, and elm, can be used. The ideal log size for growing mushrooms is around 1 meter long and 15 cm in diameter. Before use, the substrate must be pasteurized by heating it to temperatures between 65 and 85°C for 1.5 to 2 hours. This reduces the population of bacteria to give the mushroom species an advantage.
Other common substrates include brown rice flour, hardwood sawdust, and coco coir. Each substrate has its own nutritional profile, which can impact the growth rate of the mycelium and the fruiting bodies. For example, a nutrient-rich substrate may support faster growth and higher yields compared to a less nutritious option.

Liquid culture can produce multiple syringes
The number of mushrooms that can be cultivated from a single syringe varies depending on several factors. These include the species of mushroom, the quality of the spores, the substrate used, and the conditions maintained throughout the growing process.
Liquid culture syringes are often preferred by cultivators as they produce faster and more reliable results than spore syringes. Spore syringes must undergo a germination process, which takes longer and may fail to occur. In contrast, liquid culture syringes contain a single strain that has been generationally bred to achieve optimal results. Additionally, liquid cultures can be used to produce dozens of additional syringes, making them a more efficient option.
Liquid cultures are typically composed of sterile water or nutrient-rich broth containing fragmented mycelium. The mycelium is in tiny pieces suspended in the liquid, allowing for easy injection into the chosen substrate. Commercial mushroom farmers often use liquid cultures as they provide consistency and control over the growing process. By using isolated mycelium from a proven mushroom variety, farmers can predict the outcome of their cultivation efforts.
However, it is important to note that liquid cultures have a shorter shelf life than spore syringes. Liquid cultures should be used within six months of purchase, even when stored correctly in the refrigerator. On the other hand, spore syringes can last up to 12 months in the refrigerator and up to six months outside the fridge in an airtight container in a cool, dark spot.
To summarize, liquid culture syringes offer cultivators the ability to produce multiple syringes and provide faster and more consistent results. However, they have a shorter shelf life compared to spore syringes. By understanding the advantages and disadvantages of each option, growers can make informed decisions about which method best suits their needs.

The bigger the substrate, the more mushrooms
The number of mushrooms that can be cultivated from a single syringe varies depending on several factors, including the cultivation method, species, quality of spores, substrate, and environmental conditions. However, one consistent factor that influences yield is the size of the substrate.
The substrate is the material that the spores are inoculated into, providing the necessary nutrients for the spores to germinate and grow into mycelium, which eventually produces mushrooms. The type of substrate used plays a crucial role in determining the yield. Common substrates include brown rice flour, hardwood sawdust, straw, and coffee grounds, each with its unique nutritional profile impacting the growth rate and yield.
The Bulk Substrate Tek method, for example, uses a larger amount of substrate, such as straw or coco coir, resulting in higher yields. With this technique, a single spore syringe can produce several pounds of mushrooms, ranging from 500 to 1500 grams of fresh mushrooms.
The Mono Tub Method, on the other hand, involves using a large plastic container to create a controlled environment for fruiting. By optimizing humidity and airflow, cultivators can achieve multiple flushes of mushrooms, with yields ranging from 1500 to 2000 grams fresh or 150 to 200 grams dry.
The size of the substrate is a critical factor in determining mushroom yield. A bigger and deeper substrate will result in more mushrooms. This is because a larger substrate provides more surface area and nutrients for the mycelium to grow and produce mushrooms. Additionally, a nutrient-rich substrate may support faster growth and higher yields compared to less nutritious options.
Therefore, it is safe to conclude that the bigger the substrate, the more mushrooms can be cultivated from a single syringe. However, it is essential to carefully manage environmental conditions, such as humidity and temperature, to ensure successful mushroom cultivation and maximize yield.
