Use grain and sawdust spawn to grow gourmet mushrooms on pasteurised straw and hardwood chips, hardwood sawdust and hardwood logs.

Mushroom spawn is a specially prepared food source that the mushroom survives on. It is used to introduce the mycelium of the mushroom to a growing media such as straw, logs, wood chips, and nutrified sawdust.

The gourmet mushroom varieties sold in our shop are decomposing fungi.
They use plant-based dead or dying materials as a food source and a media to survive.
When the food source exhausted the fungi will starve and die.

The mushroom variety will determine what media you can use. For example:

  • Shiitake mushrooms will grow on sawdust and tree logs,
  • King Stropharia will grow on woodchips, straw and some compost mixes, and
  • Oyster mushrooms will grow on most plant-based materials but compost.

The media will determine what spawn to use.

Grain spawn is used to introduce the fungi to pasteurised straw and sterilised nutritious sources such as coffee grounds.
This can also be used to make more spawn.

Sawdust Spawn is commonly used to introduce fungi to hardwood chips, hardwood sawdust and hardwood logs.
