Our calcium sulphate is ultra-fine and food-safe, making it perfect for evenly coating and mixing through hydrated grain prior to sterilisation. One of its primary roles is acting as an anti-clumping agent; it keeps individual grains separate, which significantly increases the number of inoculation points and allows for faster, more even colonisation. Beyond texture - \u003cmeta charset=\"utf-8\"\u003ecalcium sulphate provides essential calcium and sulphur—two key nutrients that act as building blocks for vigorous mycelium growth and help stabilise the pH levels of your substrate.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"p3\"\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2 class=\"p3\"\u003e\u003cspan class=\"s2\"\u003e\u003cstrong\u003eQuality You Can Trust\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"p3\"\u003e\u003cspan class=\"s2\"\u003eWhether you are prepping jars for a gourmet grow or amending your backyard soil, our Gypsum offers a clean, reliable, and natural solution.
