The Okuda Hand Inoculator will greatly increase your log inoculation output. Ideal for farms doing less than 1,000 logs per season, this sawdust spawn inoculation tool inoculates and seals the spawn with a Styrofoam cap in one easy movement. One log can be inoculated and sealed about every two and half minutes. Includes drill bit (choose size below), enough foam caps to inoculate approx. 300 logs, and a spare set of replacement parts. Additional foam caps sold separately.
