Demystifying Spawn Workshop with Sam Shoemaker
2 – 4 p.m. February 4, 2023
1 – 3 p.m. February 5, 2023
Mushroom spawn production is one of the most challenging and misunderstood aspects of mushroom cultivation. Contaminated spawn can destroy months of work, pre-made spawn is costly, and the most popular cultivation books provide only a single 36-hour recipe!
What is spawn? Spawn, typically made from sterilized grains, is defined as any material that can transfer living mushroom mycelium to a larger mushroom growing medium, such as sawdust. We can think of spawn as the mushroom cultivator’s “seeds.” “Planting” spawn on a mushroom substrate is known as “spawning” or “inoculation.” Spawn can also be used to produce more spawn. In theory, one jar of healthy mushroom spawn can produce hundreds of pounds of harvestable gourmet mushrooms! This workshop will survey the fundamental principles of mushroom spawn in order to tailor our production for every scale, budget, timeframe and application. We will cover time-saving hacks and no-cleaning “teks” you won’t find in publications. We will discuss added precautions available for sensitive contamination-prone mushroom species. We will conclude with a live demonstration of how one might prepare the different grains commonly used by mushroom cultivators: millet, wheat berries, rye, birdseed, and milo. All materials will be provided. Recommended for new and intermediate mushroom cultivators. Price: $20 for Members, $30 for non-members
