Is it all right to use raw gypsum in the production of edible fungi?

Quicklime, or calcium oxide, is usually used. When proportioning, 1% to 5% quicklime is added, which is mainly used to regulate pH, in addition to supplying calcium for the growth of edible fungi. In addition, it can prevent the pollution of Trichoderma and other miscellaneous bacteria and buffer the organic acids produced in the process of mycelium metabolism.
