Sometimes, spawn running is very good in mushroom cultivation, but fruiting is not prompt. Here are some reasons for this phenomenon:
1. Water content is not enough in compost: the suitable water content during the formation of sporocarp is about 70%. If water content is not enough when sowing, the water content of spawn running will not reach 70%. On that occasion, spawns will grow for another several days, through respiration, water content will increase and it will get fruited. Moisturizing will be done when the water content is too little.
2. Poor ventilation or lack of sun: spawns of Oyster mushroom will produce large amounts of carbon dioxide during spawn running. When the ventilation is poor, the concentration of carbon dioxide in mushroom house will be high. On that occasion, people should open bags or punch in bag and increase the ventilation at the same time. In actual production, in order to get fruited in time, illumination can be added before 5 to 7 days of permeation of spawn.
