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 logs to inoculate year after year. Drill 12 mm holes in your logs. For fastest drilling, use a 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.
