What is Mushroom Spawn?

When it comes to mushroom cultivation, understanding the basics of mushroom spawn is essential. Whether you're a seasoned mycologist or a beginner hobbyist, knowing what spawn is and how it's used can significantly impact your growing success.

What is Mushroom Spawn?

Mushroom spawn is essentially the vegetative growth of the mushroom, which consists of mycelium, a thread-like network of fungal cells. Think of it as the seeds for mushrooms. Unlike seeds, mushroom spawn is derived from selected genetics and cloned to ensure consistent production of a specific mushroom variety. This process is similar to how apple trees are grown from grafted wood rather than seeds to maintain a particular variety's quality. Other fruits that are commonly grown through grafting to preserve specific traits include grapes, citrus fruits, stone fruits (such as peaches, plums, cherries, and apricots), pears, avocados, mangoes, persimmons, and pomegranates.

Spawn is used to inoculate a substrate, such as wood chips, straw, or compost, which then supports the growth and development of mushrooms. The 'master' cultures, from which spawn is propagated, are kept on agar petri dishes in our laboratory, ensuring a single genetic culture that can be replicated indefinitely.

Types of Mushroom Spawn

There are several types of mushroom spawn, each with its specific uses and benefits:

  1. Grain Spawn: Grain spawn is created by inoculating sterilized grain with mushroom mycelium. It is highly nutritious and provides an excellent food source for mycelium. Grain spawn is typically used to inoculate bulk substrates like coco coir, straw, or compost. This type of spawn is particularly favored for indoor cultivation and commercial mushroom farms due to its efficiency and robust mycelial growth. However, it is not suitable for outdoor log inoculation.

  2. Sawdust Spawn: Sawdust spawn is used similarly to plug spawn but requires an inoculation tool to insert the spawn into logs. This type of spawn is more cost-effective, reliable, and faster to colonize than plug spawn. Sawdust spawn is commonly used by small farms and hobbyists looking to inoculate multiple logs outdoors. Although it requires an initial investment in an inoculation tool, the lower cost of the spawn over time makes it an economical choice.

  3. Plug Spawn: Plug spawn consists of wooden dowels infused with mushroom mycelium. These plugs are easy to use and require only basic tools, like a hand-drill, to create holes in freshly cut hardwood logs. After placing the plugs in the holes, sealing them with wax helps to protect the mycelium as it colonizes the wood. Plug spawn is ideal for beginner growers and small-scale projects, providing a simple introduction to mushroom cultivation. It may take longer to see results compared to sawdust spawn, but it is a straightforward method for outdoor growing.

Why is Mushroom Spawn Important?

Using quality spawn is crucial for successful mushroom cultivation. Spawn serves several essential functions:

  • Inoculation: Spawn is the starting point for mushroom growth. Without it, you can't cultivate mushrooms.
  • Colonization: High-quality spawn ensures quick and robust colonization of the substrate, reducing the chances of contamination.
  • Yield: Good spawn can significantly increase the yield of your mushroom crop.

The Spawning of Mushroom

The spawning of mushroom involves a few essential steps:

  1. Prepare the Substrate: Depending on the type of mushrooms you're growing, you'll need to prepare a suitable substrate. This might involve pasteurizing or sterilizing materials like straw, wood chips, or coco coir.

  2. Inoculate the Substrate: Mix the spawn thoroughly with the prepared substrate. This allows the mycelium to colonize the substrate efficiently.

  3. Incubate: Place the inoculated substrate in a warm, dark place to allow the mycelium to colonize. This process can take several weeks, depending on the mushroom species and environmental conditions.

  4. Fruiting: Once the substrate is fully colonized, expose it to conditions that encourage fruiting, such as increased humidity and light.
