The Ultimate Guide to Oyster Mushroom Growing Kits

Oyster mushrooms, known scientifically as Pleurotus ostreatus, are a popular choice for mushroom enthusiasts due to their delicious taste and health benefits. They are also one of the easiest mushrooms to grow at home, making oyster mushroom growing kits a great choice for both beginners and experienced cultivators.

What is an Oyster Mushroom Growing Kit?

An oyster mushroom growing kit is a self-contained package that provides all the necessary components to grow oyster mushrooms at home. These kits are designed to simplify the mushroom growing process, making it accessible to people without prior experience in mycology.

Components of the Kit

  • Substrate: This is the material on which the mushrooms will grow. Oyster mushrooms are not picky and can grow on a variety of substrates like straw, sawdust, or coffee grounds, which are pre-inoculated with mushroom spores or mycelium.
  • Mycelium Spawn: This is the root structure of the mushroom. It is usually mixed with the substrate in the kit.
  • Growing Container: This could be a bag, box, or bucket designed to provide the right environment for mushroom growth.
  • Instructions: Detailed guidelines on how to care for your mushrooms, including information on temperature, humidity, light, and when to harvest.

Setting Up Your Kit

  1. Activation: Some kits require you to soak the substrate in water to activate the mycelium.
  2. Incubation: Store the kit in a dark place at the recommended temperature until you see mycelial growth.
  3. Fruiting: Once the mycelium has colonized the substrate, expose it to light and a bit more air to encourage mushroom formation.

Caring for Your Mushroom Kit

  • Temperature: Oyster mushrooms typically grow best at temperatures between 15-24°C (59-75°F).
  • Humidity: Maintaining high humidity is crucial. This can be achieved by misting the substrate with water regularly.
  • Light: While direct sunlight is not necessary, some indirect light helps in the growth of healthy mushrooms.
  • Airflow: Good air circulation is important, but avoid drafty areas as they can dry out the substrate.


Oyster mushrooms generally take around 10-14 days to mature after the start of fruiting. Harvest them before the edges of the caps start to curl upwards.
