Mushroom Spawn

Live Mushroom Spawn

For those looking to start their own mushroom growing project, OutGrow offers a wide variety of live mushroom spawn bags to choose from. These bags are filled with sterilized rye grains that have been fully colonized with mushroom mycelium, making it easy for you to begin your growing journey.

One of our most popular live spawn bags is our Shiitake Mushroom (Lentinula edodes) strain. This strain is perfect for both beginner and experienced mushroom growers, producing delicious and meaty mushrooms that are highly sought after. Our 3-pound bag of fully colonized Shiitake Mushroom spawn will help you get your project started off on the right path.

To ensure the highest quality and freshness, we inoculate each rye grain bag on a case-by-case basis, and we ask that you allow us 2 weeks to prepare and ship your mushroom spawn. Each bag is equipped with a filter patch to ensure proper air flow and comes ready for use on arrival.

It's important to note that live mushroom spawn is a perishable product and should be stored in a cool and dry location. We recommend using the spawn within 2 weeks of receiving it, or storing it in a cool, dry location away from direct sunlight for longer periods.

With each fully colonized 3-pound bag of mushroom spawn, you'll be able to inoculate approximately 10 pounds of bulk substrate. One pound of mushroom spawn or bulk substrate is equal to 1 quart in volume. Order now and let OutGrow help you get your mushroom project started off on the right path with our high-quality live mushroom spawn bags.
