There is an art to watering oyster mushrooms, and mastering the six observations is key
First, observe the climate. In dry weather, water more to raise humidity; in humid weather, water less.
Second, observe the water temperature. When the mushroom house temperature is above 25°C, water at night or in the early morning or evening after the air temperature has dropped.
Third, observe the mushroom house's moisture-retention performance. Mushroom houses with poor moisture retention need more watering, otherwise less.
Fourth, observe the dryness or moisture of the substrate at both ends of the mushroom bag. When the substrate is dry, the amount of water sprayed should be sufficient, and the frequency correspondingly reduced.
Fifth, observe the strength of the mycelium. When the mycelium in the substrate is strong, more water should be used, and the water for pinning and for the flush transition should be heavy; otherwise, it should be light.
Sixth, observe how many mushrooms there are. When there are many and large mushrooms on the substrate surface, the water requirement is high and moisture is consumed quickly, so the water for each flush, the flush-transition water, and the maintenance water should all be increased accordingly; otherwise, they should be light.
