=WATERING=
While the room should be kept moist, little or no water should be used
on the beds after spawning till the mushrooms begin to appear, which is
generally from six to eight weeks from time of spawning.
Then the beds at first should be sprinkled lightly every day or two
till the surface is quite moist, after that one or two sprinklings a
week will be sufficient, according to the condition of the beds. If
they get dry quickly water oftener.
