In addition, different grains, because of their kernel size and shape, will produce a different particle size when ground through the same screen. At present, considering improvements in feed efficiency, processing costs, incidence of gastric ulcers, and potential for bridging, an average particle size of 700 to 800 microns is recommended.

Jun 27, 2016· Complete spawn run usually requires 13 to 20 days. Once the compost is fully-grown with spawn, the next step in production is at hand. 4. Casing. Casing is a top-dressing applied to the spawn-run compost on which the mushrooms eventually form. A mixture of peat moss with ground limestone can be used as casing.
