Spawn rate

Inoculation rate or spawn level is defined as the weight ratio of spawn to substrate on a dry weight basis" [2]
  • straw
    • 3% - 12% of wet straw weight :"Some growers inoculate at a low rate of one 5 lb bag of grain spawn to 160 lbs of pastuerized straw, which can fill four bags with a height of 4' and a diameter of 12". A heavier inoculation rate of one 5 lb bag of grain spawn to one 40 lb straw bag, usually results in much lower contamination rates and significantly higher yields." [1]
    • 16% - 18% of dry straw [2]
    • "5 to 20%, wet spawn to dry straw" [3]
