Mushrooms are grown using a controlled process that replicates the natural conditions they need to thrive. Here's an overview of the key steps involved:

1. Selecting the Mushroom Species

• Choose the type of mushroom to grow (e.g., white button, shiitake, oyster, or portobello).
• Each type has specific substrate and environmental requirements.

---

2. Preparing the Growing Medium (Substrate)

• Common substrates: Straw, sawdust, compost, or wood chips, depending on the mushroom species.
• The substrate is sterilized or pasteurized to kill unwanted microbes and pests.
• Nutrients, like gypsum or bran, may be added to enrich the substrate.

---

3. Inoculating with Spawn

• Mushroom spores are cultured on a nutritious medium like grain or sawdust to create spawn.
• Spawn is mixed with the prepared substrate to introduce the mushroom mycelium.

---

4. Incubation (Colonization Stage)

• The inoculated substrate is placed in a dark, warm environment (20–27°C or 68–80°F, depending on the species).
• The mycelium (mushroom root system) grows through the substrate, colonizing it over several weeks.

---

5. Initiating Fruiting

• Once the substrate is fully colonized, environmental conditions are adjusted to trigger fruiting:
  • Light: Low levels of indirect light are introduced.
  • Temperature: Lower temperatures (12–18°C or 55–65°F) encourage mushroom growth.
  • Humidity: High humidity (85–95%) is maintained.
  • Air exchange: Good ventilation is crucial to prevent carbon dioxide buildup.

---

6. Harvesting

• Mushrooms are ready for harvesting when their caps open or reach the desired size.
• They are carefully twisted or cut off to avoid damaging the mycelium, allowing for subsequent flushes (harvests).

---

7. Post-Harvest Care

• Mushrooms are cleaned, sorted, and stored at cool temperatures to maintain freshness.

---

This process can be scaled from small indoor kits to large commercial operations, with each step tailored to the specific mushroom species.
