Commercial mushrooms grow in a specially formulated and processed compost made from wheat straw, hay, corn
cobs, cotton seed hulls, gypsum and chicken manure. The 3 to 4 week long composting period is closely supervised
and managed to assure that the composting temperatures exceed 160°F for a few days in addition to a steam
pasteurization which occurs about one week before mushroom spawn is mixed with the compost. Finally, a layer of
sphagnum peat moss mixed with ground limestone is top dressed onto the compost, and mushrooms grow on the
peat.
