Understand the climate when the temperature is low to take measures such as double-film insulation, summer heat should pay attention to spray water and scaffolding to cool down, try to reduce the temperature within the mushroom house.
When spraying water at a moderate temperature, water should be sprayed in the morning and at night. The water temperature should be about 30°C.
The optimum moisture content of general culture materials is 70%, the relative humidity of air during mycelial growth is 80%, and the relative humidity of the airborne fruit body is kept at 90%.
