Substrate, grains and bulk media - Sporespot.

A mushroom substrate is a material that mushroom mycelium can grow and establish itself in. The substrate provides mushrooms with the nutrients, moisture and energy they need to grow and fruit.

There are a variety of different substrates that growers use. Different species of mushrooms have their own preferences. So it’s important to match your mushrooms with the correct substrate to have the best chance of success.

A good substrate is dense in woody, fibrous materials like lignin, cellulose and hemicellulose. (These contain a lot of carbon, which is the main food source for your mycelium.)
