Spawn

Spawn comes in many forms. Which one is right for you?

The term “spawn” refers to any substance that has been inoculated with mycelium and that is used to grow mushrooms. Spawn is used to transfer the mycelium onto a substrate where your mushrooms will grow.

Mushroom Shack spawn comes in a variety of types, including grain spawn, sawdust spawn, and plug/peg spawn.

It’s best to match your spawn to the substrate you will be using. Plugs and pegs are used to inoculate logs and stumps. Sawdust/wood chip spawn are best when inoculating substrates made of wood chips, sawdust or straw, but can also be used to inoculate stumps, logs, outdoor gardens, and straw. Grain spawn works best in a grain or straw substrate.

Because Mushroom Shack spawn is custom blended at the time of each order, you should expect delivery in 2-4 weeks. The turn-around time depends on the type of spawn ordered, as grow-out time varies for each type.

Our spawn is best used in substrates that have been pasteurized or sterilized before using.
