![]() Energy (propane, gas, electric) needed to heat water.Reliable process for consistent yields on straw.Time from soaking to inoculation varies with seasonal temperatures.fruiting yields compared to weight of substrate are low.No equipment or additional treatment needed.If the ends of the logs have cracks large enough for a dime to be placed into soak the logs for 24 hours before inoculation. As long as the tree is healthy, no further preparation is needed. There is no harm in inoculating stumps, logs, or wood chips immediately after harvesting. At the same time, the wood is losing any ability to wall off an infection. Once inoculated, the mycelium takes upwards of 10 days to jump off the spawn into the substrate. Trees deal with fungal infections primarily by walling off the infection, not through antifungal compounds. There is a common misconception that logs need to sit for two weeks until inoculation, but this is not true. If temperatures are below freezing, fungi are not active so these materials can be stored until temperatures are consistently in the 40s - 50s at night. It is best to inoculate these substrates within a month of cutting. On these wood-based substrates, it takes some time for native fungi to get established. ![]() Spawn comes in three common forms: grain, sawdust, and plug. For most growers, spawn is purchased from a supplier, much like a vegetable grower buying seed from a company. “Spawn” is intentionally cultivated mycelium from a known species that has been isolated, generally in a sterile lab facility, to ensure it is free of outside contaminants. Once the strain is selected, spawn can be ordered or produced. Growers are constantly trading strains to look for the best combination of strain and substrate. Every couple of months it is good to experiment with a new strain to see if improvements can be made. If you are producing spawn in-house, its best to trial 4-5 strains side by side to see which one does best. This data also shows that proper strain selection can be the difference between a profitable farm and going out of business.Īny spawn or ready-to-fruit block provider will provide high quality strains selected for maximum performance. This illustrates how some strains are developed to consume certain substrates. 3 - 1.4 pounds per block, with strain 3782 performing the best and strain 46 doing the worst. 5 - 2.3 pounds per log, with strain LE-46 performing the best. Both had large variables in yield depending on the strain selected. The shiitake trials were done on two different substrates: logs and supplemented sawdust blocks. In the cordyceps strain trials, yields varied from 3.5 grams per jar to 11.8 grams per jar.
