How Fast Do Oyster Mushrooms Grow?
Oyster mushrooms (Pleurotus ostreatus) are one of the fastest-growing edible mushrooms, making them a popular choice for both home and commercial cultivation. Under optimal conditions, they can grow up to an inch per day, reaching maturity in just 7-10 days.
Factors Affecting Growth Rate
The growth rate of oyster mushrooms is influenced by several factors, including:
- Temperature: Ideal temperature range: 55-65°F (13-18°C)
- Humidity: High humidity (80-90%) promotes growth
- Substrate: Use substrates rich in lignin, such as hardwood sawdust or straw
- Airflow: Provide fresh air to prevent bacterial contamination
- Light: Avoid direct sunlight; indirect light or darkness stimulates growth
Stages of Growth
Oyster mushrooms grow in three distinct stages:
- Mycelium: White, thread-like network that colonizes the substrate
- Primordia: Small, pinhead-sized protrusions that develop into mushrooms
- Mushrooms: Mature, umbrella-shaped structures that can be harvested and consumed
Harvesting
Oyster mushrooms are ready for harvest when the edges of their caps begin to turn up. Use a sharp knife to cut them at the base of the stem. Avoid overwatering after harvesting, as it can promote disease.
