1. Lignin and Cellulose contained in sawdust are categorized into Polysaccharides, sawdust provides carbon element required during the growth period of Shiitake mushroom.
2. Bran offers nitrogen source for growth of Shiitake mushroom. Nitrogen content of bran is 13.5% while it is merely 2% in husk of rice.
3. Gypsum occupies a small portion on culture formula of Shiitake mushroom and it plays a significant role. And, be sure to purchase superior edible gypsum from reliable merchants. Gypsum helps buffer the function of PH Value, and constantly neutralize the organic acid metabolized during the growth process of mycelia. What’s more, gypsum is also able to regulate the PH Value of substrate, and stabilize it at the required range.
4. All living things depend on water, water content is crucial when it comes to Shiitake cropping. Low water content promotes high rate of final products. However, during the course of spawn running, moisture is constantly consumed, and it quickly evaporates during the process of hole-prick. In a word, for growers, it is best to regulate water content of auxiliary materials at above 60%.
