Another way to lower the temperature is to increase the ventilation in the growing area. This can be achieved by installing fans or opening windows in your growing area to circulate the air. This will help to dissipate the heat and keep the temperature at a comfortable level for the mushrooms Less Cooling time - Cool the storage area as quick as possible. More RH - It will reduce the weight loss due to less vapor pressure difference value. Maintain Less Surface Area - Omit the unwanted things in the produce, to reduce the transpiration rate of mushroom.
