How Much Spawn Do I Need?
To inoculate logs, we recommend drilling holes in rows, and then staggering those rows, creating a diamond pattern.
Space holes in rows 4” apart, with the rows of holes staggered 2” apart.
Use the chart below to estimate the amount of spawn and wax you will need, based on the length and diameter of the logs you plan to inoculate.

---|---|---|---|---|
Log Length | Log Diameter | Number of Plugs | Amount of Sawdust Spawn | Amount of Wax |
36" | 4" | 57 plugs | 10% of a bag | 0.11 lb |
36" | 5" | 71 plugs | 10% of a bag | 0.14 lb |
36" | 6" | 85 plugs | 10% of a bag | 0.17 lb |
36" | 7" | 99 plugs | 15% of a bag | 0.20 lb |
36" | 8" | 114 plugs | 20% of a bag | 0.23 lb |
