Reasons of green mold appearing on the back of shiitake logs?

When the spring-planted shiitake logs are being unstacked, the inoculation holes are all in good condition. However, after unstacking, green mold starts to grow on the black substrate at the back of the shiitake logs as they continue to develop. What are the reasons for this?

• The temperature difference in spring is large. If the humidity in your mycelium cultivation shed is also high and ventilation is poor, condensation water is likely to form on the surface of the shiitake logs. If there are tiny holes or cracks in the surface of the mushroom bags, they are prone to green mold infection.
• If the sterilization of the shiitake logs is incomplete, and the mycelium fails to fully colonize the black substrate at the back of the shiitake logs for a long time, it is also prone to green mold infection.

Therefore, when cultivating spring-planted shiitake logs in spring, try not to transfer them from the mycelium cultivation shed to the fruiting shed too early. During the mycelium cultivation period, maintain a constant temperature, minimize temperature differences, allow the mycelium to fully colonize quickly, and puncture large holes in the shiitake logs as early as possible. Only in this way can the risk of over-summering be avoided.
