Growing Parameters for Various Mushroom Species/ 163

Lighting: None required.
C02: less than 2000 ppm.
Fresh Air Exchanges: 2-4 per hour.
Watering: Regular misting (once to twice daily) of the beds stimulates primordia formation.

Croppi rig:
Relative Humidity: 85-92%.
Air Temperature: 75-77 °F.
C02: less than 3000 ppm.
Fresh Air Exchanges: 2-4 per hour.
Flushing Interval: Every 8-9 days.
Harvest Stage: Directly before the partial veil stretches.

Yield Potential: Average commercial yields are reported at 3 lbs/sq.ft. over a 5 week cropping
period. Maximum yields are 4 lbs per square foot.

Moisture Content of Mushrooms: 92% water; 8% dry matter.
Nutritional Content: Thought to be similar to Agaricus brunnescens.
Comments: The development of Agaricus bitorquis has given commercial growers greater flexibility, especially those in warmer climates where elevated temperatures have been a limiting factor.
An advantage of this mushroom is its resistance to virus (a devastating disease that attacks A.
brunnescens) and its tolerance of high CO2 levels. A disadvantage of growing this warmth-loving
Agaricus is the higher incidence of disease endemic to the temperature range in which this species
flourishes. Agaricus bitorquis is coarser, firmer, more strongly flavored and has a longer shelf life
than its close relative, A. brunnescens.
Genetic Characteristics: Basidia tetrapolar (4-spored), forming haploid spores, heterothallic. The
mating of compatible monokaryons can result in fruiting strains. Clamp connections absent. See
Chapter XV.
