Pre-Sterilized Oat Grain Spawn

This 2.5-pound grain spawn is designed for optimal mushroom cultivation. It’s packaged in a high-quality Unicorn injection port bag, making inoculation simple and contamination-resistant. The bag is durable, with a built-in filter patch for proper gas exchange, ensuring your mycelium grows strong and healthy. The grain is pre-sterilized to eliminate contaminants, so you don’t need any extra equipment—just inoculate and let it colonize. Perfect for both beginners and experienced growers looking for a hassle-free, professional-grade setup.

1. Sanitize your work area with 70% isopropyl alcohol to maintain cleanliness.

2. Inoculate the bag by injecting liquid culture directly through the injection port using a sterile syringe.

3. Place the bag in a warm, dark area (ideally 20–24°C / 68–75°F) to allow mycelium to colonize the grain.

4. Once fully colonized, break up the grain gently to distribute the mycelium evenly if needed.

• It’s recommended to use the grain spawn immediately after receiving it for the best results.

• If not used right away, it can be stored for up to 1 month in a cool, dry place away from direct sunlight, but prolonged storage can increase the risk of contamination, even in sterile conditions.

• Tip: If you’re not using it right away, you can refrigerate the bag to extend its shelf life.
