Chinese Shiitake Logs: From Prepared Substrate to Fresh Mushroom Harvest

Growing shiitake mushrooms requires the right substrate, suitable environmental conditions, and careful management during the fruiting stage. Prepared mushroom logs can make this process more organized by providing a substrate that has already been inoculated and colonized with shiitake mycelium.

Agrinoon - Chinese shiitake logs are prepared mushroom-growing substrates containing established shiitake mycelium. Once the colonization process is completed, the logs can be used for mushroom production. Under suitable conditions, the first flush can be harvested approximately 7–11 days after the bags arrive.

Understanding the Prepared Shiitake Growing Medium

The growing medium is an important part of shiitake cultivation because it provides the foundation for mushroom development. The supplied logs contain mycelium that has already developed throughout the substrate. The visible white or brown material inside the bags represents the colonized growing medium.

Instead of beginning with the inoculation process, growers can work with a prepared substrate and concentrate on creating the appropriate environment for fruiting. Cultivation guidance can also help with managing the different stages of mushroom production.

Product Size, Weight, and Expected Production

The prepared shiitake logs are approximately 10 × 40 cm in size, measured by diameter and length. Custom sizes are also available according to the specified requirements.

Each bag weighs around 1.6–1.7 kg, while the expected yield is approximately 0.6–0.8 kg per bag. The listed shelf life is around three to five months.

These specifications provide useful information when planning cultivation space, storage, and expected mushroom production.

Creating the Right Fruiting Environment

Environmental management is one of the key factors during shiitake fruiting. The recommended temperature range is 5–25°C, with 15–18°C identified as the optimal range.

Humidity should generally remain between 80% and 95% around the mushroom logs. The recommended carbon dioxide concentration is 700–1100 ppm, while lighting requirements are approximately 500–1500 lux.

Temperature differences are also part of the cultivation process. The information provided describes a variable-temperature strain requiring temperature-difference stimulation of approximately 8–10°C.

Maintaining these conditions helps create an environment appropriate for the fruiting stage.

How the Logs Are Prepared

Before the growing logs reach the cultivation stage, the substrate passes through several production steps. These include bagging, high-pressure sterilization, purification, cooling, automatic inoculation, finished inoculation, cultivation, fruiting, and packing.

Sterilization is used as part of the preparation process before inoculation. Following inoculation, the substrate remains in cultivation until the mycelium has developed through the growing medium.

Once the preparation and cultivation stages are completed, the finished logs are packed for use in mushroom production.
