Gypsum (Calcium Sulphate) for mushroom substrate

Enhance your mushroom cultivation with our Gypsum (Calcium Sulphate), an essential additive for optimising substrate quality. Gypsum substrate or supplement plays a crucial role in providing calcium, preventing substrate clumping, and promoting robust mycelium development.

Key Benefits:

• Calcium Enrichment: Gypsum supplies vital calcium, strengthening cell walls and supporting healthy mushroom growth.

• Improved Substrate Structure: By preventing clumping, gypsum ensures a loose, aerated substrate, facilitating efficient colonisation.

• pH Stabilisation: Gypsum helps maintain a stable pH level, creating an optimal environment for mycelium proliferation.

Usage Recommendations:

Incorporate up to 5% gypsum by dry weight into your mushroom substrate mix for best results. For example, add 50 grams of gypsum to 1 kilogram of dry substrate components.

Available Sizes:

• 250g bag

• 500g bag

Our gypsum is 100% pure containing 23% Calcium and 18% Sulphur, ensuring the highest quality for your cultivation needs. Whether you're a hobbyist or a professional grower, integrating gypsum into your substrate preparation can enhance your mushroom production.
