Sawdust spawn consists of mycelium grown into hardwood sawdust and is the preferred spawn of many commercial growers. Log inoculation can be mechanized with specialized tools. Drill holes using a 12mm drill bit with stop. Make the job quicker and easier and drill your holes with an angle grinder by pairing this bit with our angle grinder adapter. A faster spawn run makes sawdust spawn more economical to use than plug spawn. Sawdust spawn is sensitive to drying out and must be kept moist throughout the inoculation process. Each inoculation site should be immediately sealed with a wax coating (we use melted cheese wax).
Sawdust spawn is used for Shiitake, Oyster, Wine Cap, Nameko, Almond Agaricus, Blewit, Maitake, Lion's Mane, Comb Tooth, and Olive Oysterling mushroom cultivation.
One 5.5 lb. bag of sawdust spawn will inoculate approx. twenty-five 4" by 40" logs.
