Our Proprietary Strains of Shiitake Spawn.
Plug Spawn is the easiest type of spawn to inoculate logs with. The plugs are 5/16" diam. x 3/4" long. Just drill the holes tap the plugs with a hammer, and apply wax. For more information on inoculating logs see our page on Inoculating Logs in our Resources section.
Each Bag contains 1000 Plugs - enough to do approximately 30 logs that are 4" in diameter and 40" long.
Unopened Spawn bags can last 2 to 6 months if refridgerated depending on conditions.
For detailed information on the different strains, please see the About Our Spawn section of our website.
