Elm Oyster Mushroom Liquid Culture Syringe

Our Elm Oyster Liquid Culture Syringe is designed for easy and reliable mushroom cultivation at home. Each syringe contains 10ml of high-quality Pleurotus ulmarius mycelium, carefully suspended in a nutrient-rich liquid medium for optimal growth. To ensure a smooth and sterile inoculation process, the syringe comes with a sterile 16-gauge needle and an alcohol wipe. Elm Oyster mushrooms are prized for their thick stems, rich umami flavor, and vigorous growth, making them a fantastic choice for both beginner and experienced growers looking for a high-yield variety.

Getting started with our Elm Oyster liquid culture is simple and beginner-friendly:

1. Refrigerate upon arrival – Keep the syringe fresh by storing it in the fridge.

2. Shake before use – Mix the mycelium evenly by shaking the syringe thoroughly.

3. Inoculate your substrate – Inject the liquid culture into sterilized grain bags, jars, or supplemented sawdust using a self-healing injection port.

4. Maintain sterility – Work in a clean environment, such as a still air box or flow hood, to prevent contamination.

Ensure a successful harvest by following these expert tips:

• Temperature: Elm Oyster mushrooms thrive in temperatures between 60–75°F (16–24°C), making them adaptable to various growing conditions.

• Substrate: Use sterilized grain or hardwood-based sawdust for optimal growth and high yields.

• Yields: Expect around 0.5–1 lb of fresh mushrooms from the first flush, with the potential for multiple harvests over time.

• Humidity: Maintain high humidity levels (80–90%) to encourage strong fruiting and prevent drying out.

With the right setup, your Elm Oyster mushrooms will grow quickly, rewarding you with meaty, flavorful mushrooms perfect for cooking!
