How should spring-planted shiitake be sprayed with water in summer?

1.If the highest temperature of the day is 30°C or below, and the lowest temperature is below 20°C, it is sufficient to ensure good ventilation for the shiitake logs. There is no need to spray water on the logs to cool them down. Because under such temperatures, the shiitake logs temperature will only reach around 32°C at the highest in the afternoon. As long as ventilation is good, the temperature will naturally drop in the evening.

2.If the highest temperature of the day is between 30-32°C, we only need to appropriately spray water in the space to cool down when the temperature is the highest in the afternoon. Spray for 2-3 minutes each time, and repeat after every other hour. In this way, the shiitake logs temperature can be kept below 30°C all the time.

3.If the highest temperature of the day is between 33-35°C, it is necessary to spray water on the shiitake logs to cool them down at noon before their temperature rises. , spray for 15-20 minutes each time, and then spray again for 15-20 minutes after every other hour. Due to the relatively high external temperature, we should try to reduce ventilation during the day and increase ventilation for the logs in the evening when the temperature drops.

4.If the highest temperature of the day is 35-38°C, it is necessary to start spraying water on the shiitake logs to cool them down from the morning. Spray for 30 minutes each time, and then spray again for 30 minutes after every other hour, so that the temperature of the shiitake logs is always kept below 30°C. Since the external temperature is high, when spraying water on the shiitake logs, try to reduce ventilation to prevent hot air from outside from entering. In the evening, increase ventilation for the shiitake logs as soon as the external temperature drops.

In addition, when spraying water on the shiitake logs to cool them down, it should be noted that : water is sprayed on the shiitake logs during the day, after the temperature drops in the evening, it is necessary to significantly increase ventilation for the shiitake logs. This way, the mycelium in the shiitake logs is less likely to suffer from oxygen deficiency and suffocation, and the shiitake logs are less likely to rot in the later stage.

Moreover, while spraying water on the shiitake logs inside the shed, try to also spray water on the top of the shed from the outside. This prevents the hot air outside from coming down, making it easier to cool the shiitake logs.
