Plug spawn is very easy to use and requires tools that are found in most households. You will need a proper size drill bit to drill holes, a hammer to tap the plugs into the holes, and a paintbrush or wax dauber to apply melted wax to cover them. To easily drill holes to the proper depth each time, fit a depth stop on your 8 mm (5/16″) drill bit or purchase a special high speed 8.5 mm drill bit with built-in depth stop. Sawdust spawn requires the purchase some special tools, but is a more economical option if you have lots of log to inoculate year after year. Drill 12 mm holes in your logs. For fastest drilling, use this 12 mm drill bit with built-in depth stop with an adapter to convert your angle grinder to a high speed drill. Fill the inoculation tool with sawdust spawn, and “punch” the pellet into the hole. Cover with melted wax using a wool dauber.
