Sawdust Plunger Inoculator

Quickly Fill Mushroom Logs with Sawdust Spawn

Make log inoculation faster, cleaner, and much easier with our sawdust spawn plunger inoculator.

Designed to pick up and inject sawdust spawn directly into pre-drilled holes, this spring-driven tool lets you inoculate logs and stumps efficiently without trying to pack spawn into every hole by hand.

Made with durable brass components and a molded handle, these inoculators are built for repeated use. We've had the same brass plunger at Mushroom Mountain for more than 10 years — these little things are workhorses.

🍄 Designed for Sawdust Spawn

The inoculator works by pressing the tip into loose sawdust spawn, filling the chamber, and then using the spring-driven plunger to inject the spawn into your drilled inoculation hole.

For best results, pair it with our 12 mm mushroom log inoculation drill bit, which creates holes sized for sawdust spawn inoculation.
