Sterilized Grain

Our sterilized grain bags are filled with hydrated local and organic grains, precision-processed and sealed with a self-healing injection port and filter patch from Unicorn bags. They’re ready to be inoculated with your preferred liquid culture (or other method of your choice) whether you're growing gourmet or functional mushroom species. Each 4T Unicorn bag is sterilized under pressure for maximum cleanliness and consistent results.

FAQ

  • What kind of grain is used?

    In mushroom cultivation the "Best" grains to use for spawn is highly debated amongst the community. As such we look to offer a variety of grains, but focus on local availability and organic grains. We only offer the same grains that we use ourselves.

  • Do I need a sterile environment to inoculate?

    Ideally inoculation should be done in a sterile environment using proper technique. However, we recognize that comes at a cost which beginners arnt ready to invest in. That said and with the proper technique and some some low-cost supplies it is more than possible to inoculate and grow mushrooms in a non-sterile environment. See our knowlegde base for more information.

  • Storage & Shelflife

    If unused, store in a cool, dark place or refrigerate to extend shelf life. If refrigerated , we recommended inoculating within 3 months. After 3 months, grains may begin to dry out, clump, or become less viable for inoculation. Aim to use within 30–60 days for best results.
