Introducing Out Grow's live Chestnut Mushroom (Pholiota adiposa) spawn! Our 3-pound bag of fully colonized mushroom spawn will help you get your mushroom project started on the right foot. Please allow us 2 - 3 weeks to prepare and ship your mushroom spawn as we inoculate each rye grain bag on a case-by-case basis to ensure that every order is made fresh, unless otherwise specified. In some cases, we may be able to ship sooner than 2 weeks.

Each bag consists of 3 pounds of sterilized rye grains inside a mushroom grow bag with a filter patch. The rye grains will be fully colonized with the Chestnut mushroom mycelium and ready for you to use on arrival.

Chestnut mushrooms are a cold-weather strain and should be kept at a temperature between 50-60 degrees Fahrenheit. 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. If you need to store it for longer periods, keep it in a cool, dry location away from direct sunlight.

Our Chestnut mushroom strain is a tasty and hearty strain, perfect for both beginner and experienced mushroom growers. With our live mushroom spawn, you'll be able to grow these delicious mushrooms at home with ease.

Each fully colonized 3-pound bag of mushroom spawn can inoculate approximately 10 pounds of bulk substrate. One pound of mushroom spawn or bulk substrate is equal to 1 quart in volume.

Please note that live mushroom spawn will ship separately and it will take 2 weeks to prepare and ship. Order now and let Out Grow help you get your mushroom project started off on the right foot with our Chestnut Mushroom spawn!
