PureGrow Supply Superfine E516 Food Grade Gypsum</strong> is a high-purity calcium sulphate dihydrate (CaSO₄·2H₂O), free from additives and finely ground to an ultra-fine consistency. This texture ensures it mixes easily and distributes evenly across different mediums.

In brewing, gypsum is used to modify water chemistry by adding calcium and sulphate ions. It helps balance pH, enhance enzyme activity during mashing, and improve clarity and flavour—supporting a crisp, dry finish in the final product.

In baking, it functions as a dough conditioner—reducing stickiness, regulating acidity, and improving the texture and stability of baked goods. It also serves as a calcium source, supporting flour treatment and leavening in selected recipes.

In mushroom cultivation, gypsum acts as a pH buffer within the substrate. It helps maintain proper structure and moisture balance while providing essential minerals like calcium and sulphur that support healthy mycelium development and consistent yields.

In gardening, gypsum serves as a natural soil conditioner, especially useful in compacted or clay-heavy soils. It improves drainage, enhances water movement, and supplies calcium and sulphur without relying on synthetic fertilizers.

Packaged in a resealable pouch to keep it fresh and easy to use whenever you need it.
