$30.00

Our organic grain spawn is sold in 1 kilogram (~2.25 pounds) bags fully colonized. It is made with organic rye berries, organic brown rice, and a unique proprietary blend of organic nutrients and minerals, resulting in robust and fast-growing mycelium. This bag has the potential to colonize up to 45 lbs of substrate, maximizing your harvest. It is recommended that the spawn be used upon arrival to achieve the best results. Although refrigeration can extend the spawn's shelf life up to 6 months, using it earlier (within 3 months) will promote faster growth and minimize contamination risks.
