Gypsum - Superfine White High Purity

Gypsum (CaSO₄·2H₂O) – Premium Grade for Mushroom Cultivation

Give your mushroom crops the boost they deserve with our high-purity Gypsum (Calcium Sulfate Dihydrate), specially selected for mushroom cultivation. Gypsum is an essential mineral supplement in many substrates and spawn mixes, providing both calcium and sulfur—vital for strong mycelial growth and consistent yields.

Key Benefits:

• Prevents Clumping – Improves substrate texture, keeping grains and bulk materials loose and airy for better colonization.

• Balances pH – Helps stabilize pH without over-alkalizing, creating an optimal environment for mushroom mycelium.

• Adds Essential Minerals – Supplies calcium for cell structure and sulfur for healthy metabolic function.

• Improves Water Management – Enhances moisture retention while preventing overly wet spots that could lead to contamination.

Recommended Uses:

• Add 2–5% by dry weight to grain spawn (wheat, millet, sorghum, etc.) before sterilization.

• Blend into bulk substrates like chopped straw, coco coir, or compost for improved structure and mineral content.

• Ideal for oyster, shiitake, lion’s mane, and other gourmet or medicinal mushrooms.

Composition:

• Chemical Formula: CaSO₄·2H₂O

• Purity: >90% Calcium Sulfate Dihydrate, Analysis Certificate available on request.

• Form: Fine powder

💡 Tip: Gypsum works best when evenly mixed into your substrate before hydration and sterilization/pasteurization.
