Maitake Spawn

Regular price $16.00

Lead time 2-4 weeks

Spawn is pure mushroom tissue grown on a prepared material that is used for the production of quality mushrooms. Our specialty sawdust spawn is crafted from sustainably sourced hardwood sawdust and pure tissue culture from select strains. We offer 14 different strains and have over 40 cultures on hand to meet your cultivation needs. Sawdust spawn is the preferred spawn to use for specialty mushrooms grown on sterilized sawdust and on logs, as the mycelium has already been introduced to the material in which it will fruit. Every batch of spawn is thoroughly inspected and tested at our commercial farm in Moss Landing, CA, where we grow over 18,000lbs of fresh mushrooms each week.

(One unit starts as a 5lb bag of spawn)

One bag of spawn can inoculate up to 300lbs of material

Cultures are used for the production of spawn and are essential for any commercial operation intending on producing spawn. We offer mother cultures for over 40 strains available in petri dishes or slants. Fresh cultures are sold with the confidence that they have been tested at our facility and will produce highly productive crops. A duplicate copy will be included with every purchase. Each culture is labeled with a code to verify cell line, age, transfer value, duplicate number, and media type.

For questions and information about our spawn and culture orders please feel free to email us at or call us at 831.728.5469
