Quick Answer
Inoculating logs with mushroom plugs requires careful preparation, precise technique, and proper maintenance to achieve successful mushroom cultivation. This involves sterilizing the logs, preparing the mushroom plug, and inoculating the logs with the plug. A well-planned approach is key to successful inoculation.
Preparing the Logs
Preparing the logs for inoculation begins with selecting the right logs, typically made from deciduous trees like oak or beech. The logs should be 3-4 feet long, 3-6 inches in diameter, and have a moisture content between 30-50%. Sterilize the logs by submerging them in water at 160°F (71°C) for 30 minutes, then soaking them in a solution of 1 part bleach to 10 parts water for 10 minutes.
Inoculating the Logs
Once the logs are prepared, create the mushroom plug by mixing 1 part mycelium (mushroom spores) with 2 parts sawdust, and 1 part vermiculite. The mycelium should be active and have a healthy appearance. Use a clean, sterile knife to cut the log and insert the plug, making sure it is centered and 1-2 inches deep. Seal the cut with wax or melted paraffin.
Maintaining the Logs
After inoculation, maintain a consistent temperature between 40-55°F (4-13°C), and maintain high humidity. Keep the logs in a shaded area, and avoid direct sunlight, which can cause the logs to dry out. Check the logs regularly for any signs of contamination or pests, and maintain a consistent moisture level by misting the logs with water periodically.
