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 a wide variety of commercially viable strains, with over 40 cultures maintained in our culture bank 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
