Sterilised grain jar

Our sterilised grain jars are an excellent match for liquid cultures, offering a simple and efficient way to expand mycelium for mushroom cultivation. Each jar is carefully prepared using heat sterilisation to ensure a contamination-free environment, giving your mycelium the best possible start. Designed for convenience, these jars are ideal for both beginners and experienced growers looking to save time and effort in their cultivation process.

Storage Instructions:
After receiving our sterilised grain jars, store them in a cool, dry place away from direct sunlight. Ideally, keep them at room temperature (between 18°C and 22°C). Do not refrigerate, as this can introduce moisture and increase the risk of contamination. For best results, inoculate the jars with liquid culture as soon as possible after receiving them. If immediate use isn’t possible, ensure the jars are stored in their original sealed packaging to maintain sterility, and use them within 2–4 weeks for optimal freshness.

Please note: The jars and lids used for our mushroom grain spawn may differ in appearance from the photos due to supplier availability. However, the jar size remains the same, and this does not affect the quality, freshness, or performance of the grain spawn inside.
