Plug Spawn for Logs

Plug spawn is mycelium grown into hardwood dowels which can be easily tapped into holes drilled into a log. It's a natural choice for small projects because it is easy to use, requires no special tools and is available in small quantities. Use an 8.5mm bit with stop (or a 5/16" drill bit) to drill the logs, and a hammer to tap them in. Once the holes are filled, seal them with wax to prevent the spawn from drying out.

Plug spawn is extremely durable - we recommend it for fall inoculations in cold climates and stump inoculations. Although it takes nearly 30% longer than sawdust to colonize a log and is more expensive than sawdust spawn at equivalent inoculation rates, it is an excellent spawn type choice for beginners and small projects.
