Description
This Calcium Carbonate is made from limestone.
In mushroom cultivation, it serves as a PH buffer for the substrate. This means that the PH will remain steady as the mushroom grows. When mycelium expands, it releases acid compounds to help digest the substrate media. These acids could drastically change the PH of the substrate, making it difficult for mushrooms to fruit. Calcium carbonate prevents the substrate from becoming too acidic for the mycelium to produce fruits. Depending on the method, soak, boil, and dry your grains and then add Calcium Carbonate. Mix well and then sterilize.
Usage Recommendation:
- Add 5% of Calcium Carbonate relative to the total weight of your grain spawn.
Important Note:
- Calcium Carbonate is not suitable for pasteurization. For pasteurization purposes, refer to our listing for Calcium Hydroxide Ca(OH)2.
