Description
Gypsum Calcium Sulphate  (CaSO4) mushroom supplement grain and substrate
Our gypsum is coarse-grade and of the highest quality available on the market. They come straight from a quarry and are broken up in our facility to at least half their size(1-2mm).
Our gypsum gives you better results than food grade and Bunnings ones, comes without any added ingredients, and is 100% natural, additive and processing-free.
Gypsum may be added at any stage of mushroom cultivation. It is a versatile compound that provides essential minerals for healthier mycelium growth due to its high content of calcium and sulfur, which leads to bigger yields and higher chances of success. Â The key features of Calcium sulfate are:
- Â Prevention of sticking and clumping when added to grain spawn, leading to more prominent mycelial points of contact, reducing chances of contamination
- Increased moisture distribution when added to the substrate
- Enhanced yields and fruit body formation
Depending on the method, soak, boil, and dry your grains, and then add gypsum. Mix well and then sterilize.
Ratio:
- Add 3% of Gypsum of the total dry weight when adding to grains
- Add 5% of Gypsum of the total dry weight when adding to the substrate
