Dampness – Relative humidity inside and outside the barns should be checked and kept at a suitable level. In general, relative humidity during the harvest period should be between 80-90%. Dampness inside the barns relates to the temperature outside. Therefore, in winter when the weather is dry, you should cover inside the barns with plastic sheets, close doors and windows to prevent the dampness evaporating. Watering 3 times per day will help keep the growing barn appropriately damp. In summer, the temperature outside is high so you should water many times in order to keep the barns damp. Watering the ground, wall and roofs and ventilating the air will help with controlling the dampness inside the barns.
Food formula – Food formula has to be standard and contains appropriate ingredients for the mushrooms needs. Using the wrong growing materials could cause an imbalance of material digestion along with chemical and physical change, affecting the mushrooms quality and change in their nutrients.
