Start growing more mushrooms at once to get successive harvests by choosing this bulk grain spawn option. Each bag includes an adhesive self-healing injection port. Bulk rye grain is contained in genuine 3T Unicorn Bags with a 0.2 micron filter patch to protect against contamination.
This bulk grain bundle also allows beginners to practice grain-to-grain transfers by inoculating one bag of grain, and after colonization, the grain spawn can be used to inoculate two more bags, plus 1-3 fruiting substrate of choice.
Organic Rye Berries are hydrated and sterilized, packaged in UV-resistant, airtight packaging, with a 12 month shelf life. Ready to use when you are.
