Standard Spawn Medium: Rye grain. See Chapter III. Fruiting Substrate: Rye grain; wheat straw; leached horse or cow manure; and/or horse manure/straw compost balanced to a 71-74% moisture content. Method of Preparation: See Chapters III, V, and VI. Pasteurization achieved through exposure to live steam for 2 hours at 140°F. throughout the substrate. Straw or Compost should be filled to a depth of 6-12 inches. Straw should be Spawned at a rate of 2 cups/sq. ft. Spawn Run: Relative Humidity: 90%. Substrate Temperature: 84-86 °F. Thermal death limits have been established at 106°F. Duration: 10-14 days. CO2: 5000-10,000 ppm. Fresh Air Exchanges: 0 per hour. Type of Casing: After fully run, cover with the standard casing whose preparation is described in Chapter VIII. Layer to a depth of 1-2 inches. The casing should be balanced to an initial pH of 6.8-7.2. Post Casing/Prepinning: Relative Humidify: 90 + %. Substrate Temperature: 84-86°F. Duration of Case Run: 5-10 days. CO2: 5000-10,000 ppm. Fresh Air Exchanges: 0 per hour. Light: Incubation in total darkness. Primordia Formation: Relative Humidify: 95-100%. Air Temperature: 74-78 °F. Duration: 6-10 days. CO2: less than 5000 ppm. Fresh Air Exchanges: 1 -3 per hour. Light: Diffuse natural or exposure for 12-16 hours/day of grow-lux type fluorescent light high in blue spectra at the 480 nanometer wavelength. (See Chapters IV and IX). Cropping: Relative Humidify: 85-92% [Cased Beds] Air Temperature: 74-78 °F. CO2 : less than 5000 ppm. Fresh Air Exchanges: 1 -3 per hour. Flushing Pattern: Every 5-8 days. Harvest Stage: When the cap becomes convex and soon after the partial veil ruptures. Light: Indirect natural or same as above. Yield Potential: Average yields are 2-4 Ibs./sq.ft. over a 5 week cropping period. Maximum yield potential has not been established. Moisture Content of Mushrooms: 92% water; 8% dry matter. Nutritional Content: Not yet established. See: Longevity
