Mycelium breaking through the casing surface early should be lightly sprinkled with moist cas-

ing. Uneven growth through the casing layer is usually an indication of a casing with irregular
depths. By "patching" shallow areas, an even mycelial spread is assured. Note that the more even

the distribution of the mycelium in the valleys of the casing's surface, the more even the
pin-set and the greater the first and second flushes.
The exact time for initiation varies with the strain and according to the experience of the individ-

ual grower. Some strains continue to grow vegetatively for a period after the initial temperature
shock whereas others stop immediately. For this reason, some cultivators initiate when 20% of the
valleys show mycelial growth while others wait until 90% are run through with mycelium. Normally
within 12-48 hours from the time the mycelium is first visible in the valleys, the initiation sequence
is started.

The first step in the pinhead initiation process is to lower the substrate and air temperature from

the mycelial growth optimum to the fruiting range. This temperature "shock" is accomplished by
ventilation with a large volume of cool fresh air, thereby lowering the room's temperature to a point
below the optimum for spawn running. (For Agaricus brunnescens, this would mean dropping air temperature from 70 °F. to 64°F.). Whatever the air temperature may be, the bed temperature is normally several degrees warmer. The length of time needed to affect this change is determined by the total volume of substrate and the temperature of the air being introduced. Within 48
hours, the substrate temperature should fall to fruiting temperatures, effectively slowing vegetative
growth. This change signals to the mycelium that it is time to fruit.
