Growing Parameters for Various Mushroom Species/i 91

GROWTH PARAMETERS
Mycelial Types: Fast growing rhizomorphic to linear mycelia noted. Color is typically whitish.

Spawn Medium: Rye grain. See Chapters III.

Fruiting Substrate and Method of Preparation: Cereal straw (normally wheat) balanced to a
75% moisture content. The straw, chopped or whole, is pasteurized by submerging in a 160°F.
water bath for 30-45 minutes. An alternative method utilizes live steam pasteurization at 1 40°F. for
6 hours. In Japan, P/euro tus is grown on a mixture of hardwood sawdust and bran (4 parts to 1,

65% moisture and a pH of 6.8-7.0). This mixture is sterilized for 1 -2 hours at 1 5 psi. Being a
primary decornposer, Pleurotus grows on a wide variety of cellulosic wastes.

Spawn Run:
Relative Humidity: 90-100%.
Substrate Temperature: Fastest growth at 78-84°F. Thermal death occurs if mycelium is held
above 104°F. for 48 hours.
Duration: 10-14 days for complete colonization.

C02: 20,000 ppm or 20% CO2 by volume. (Growth is stimulated up to 28,000 ppm).
Fresh Air Exchanges: 0 per hour.
Light: Incubation in total darkness.

Type of Casing: None needed.

Pinhead Initiation:
Relative Humidity: 95%.
Air Temperature: 55-60 °F.
Duration: 7-1 4 days.
C02: less than 600 ppm.
Fresh Air Exchanges: 4 per hour.
Light: Phototropic, most responsive to an exposure of 2,000 lux/hour for 12 hours/day.
Grow-lux type fluorescent lighting is recommended. Diffuse natural light is sufficient.
Watering: Regular misting once to twice daily until fruitbodies are 30-40% of harvest size and
then water as needed to prevent caps from cracking.

Cropping:
Relative Humidity: 85-92%.
Air Temperature: 60-64 °F.
Duration: 5-7 weeks.
C02: less than 600 ppm.
Fresh Air Exchanges: 4-6 per hour or sufficient to meet CO2 and/or cooling requirements.
Haniest Stage: Directly before incurved margin elevates to plane.
Flushing Interval: 1 0 days.
Light: Same as above.
