Agar is usually the medium of choice for the spores. Cultivating mushroom starts with a spore which germinates into hyphae. This process includes,
- Transfer spores to agar
- Grow them into mycelium
- Transfer the mycelium to grain
- Incubate the spawn
- Transfer the spawn to the final medium
- Raise them to adult mushroom stage
Important Note: In a sterile environment only, mushroom cultivation is possible in agar.
