Sawdust Spawn

 

Bolts can be inoculated with sawdust spawn instead of plug spawn. There are advantages and disadvantages to each. Plug spawn is very simple to use, as shown in our pdf file on plug spawn- take the wooden plug, tap it into the hole you've drilled, cover it with wax. The only tool needed is a hammer or mallet. The drawbacks are that plug spawn is slightly more expensive per log than sawdust spawn, and the mycelium may take a while to migrate out from the plug spawn.

Sawdust spawn is slightly cheaper than plug spawn, but it requires a special tool, either purchased or home made, to insert the sawdust in the hole. In addition to its lower cost, the mycelium contained in sawdust spawn moves out into the log more quickly, giving somewhat faster production. Other than that, the methods are the same between inoculating logs with plug spawn and with sawdust spawn.
