Fresh, lab-grown grain spawn, made to order in Ohio.
Every bag is fully colonized grain spawn (about 1.6 kg) produced under sterile conditions in a filter patch bag. Order made fresh to order and we inoculate your bag after you buy, so it arrives at peak vigor, or check our Ready to Ship page for batches on hand now.
New to growing? Pearl and Blue Oyster are the most forgiving. Want something special? Try Lion's Mane, King Trumpet, Pioppino, or Golden Chestnut. Planning a garden bed? Wine Cap grows outdoors in wood chips.
