Humidity
Subtract the water content in the highly influential on the growth and development of fungal mycelium.
Too little water will result in the growth and development will be disrupted, even stopped altogether. However, if too much water, the mycelium will rot and die. Subtract the water content in the plant will be obtained with a good watering when it's done.
Fungus grows well in moist conditions, but do not want the pool of water. Oyster mushroom mycelium grows optimally at subtract that has a water content of about 60%. As for the body to stimulate the growth of shoots and fruit, need humidity around 70-85%.
