Upstairs are two blower .
For uniform air flow distribution , we have established an iron sheet , which directs the air flow along the ceiling of the mushroom room.
See it in pumping fans . First they pumped air from the technical room .
Then we decided to pump air directly from the street .
This pipe is connected to the street.
Simultaneously with the blower exhaust fan running . It is located at the bottom because it is at the bottom of the carbon dioxide plant accumulates.
Link is good.
In one hour, all the air in a mushroom indoors manages several times renewed.
This is a very good effect on the yield of mushrooms.
This resulted in increased yield of mushrooms of 20 %.
