Olympus Myco 97% Pure Gypsum Powder – High Solubility Calcium Sulfate for Soil, Gardens & Mushroom Substrates

Elevate soil and substrate health with Olympus Myco 97% Pure Gypsum Powder

Olympus Myco 97% Pure Gypsum Powder is a premium soil amendment designed to support healthy structure and substrate performance. The fine, clean powder blends smoothly into soil, potting mixes, and mushroom substrates, helping lay a solid foundation for roots and mycelium alike. Because the product dissolves readily in water, the minerals become accessible to your plants and fungi without heavy mixing. The high purity—97 to 99 percent calcium sulfate dihydrate—offers a consistent supply of calcium and sulfur while helping maintain a balanced feel in your growing medium.

In practice, the powder’s properties translate into easier handling, better texture, and more uniform moisture distribution across the growing medium. By reducing compacted layers, it can encourage air movement and healthier root and mycelium networks, even in mixed soil or substrate environments. This makes it a versatile addition to gardens, lawns, and growing operations where substrate health matters.

Key benefits

• Improves soil and substrate structure by reducing compaction and boosting air movement for healthier roots and mycelium.
• Delivers essential calcium and sulfur to support growth while helping maintain a balanced growing medium.
• Promotes even moisture distribution to prevent dry pockets and soggy zones.
• Loosens texture and reduces clumping for easier mixing and deeper penetration of water and nutrients.
• Solution-grade purity (97-99%) supports consistent performance and helps minimize erosion in outdoor beds.

Ideal uses

• Gardens and lawns: dust or broadcast into the topsoil, then rake and water to integrate.
• Mushroom substrates: blend into the substrate before inoculation to improve structure and aeration.
• General soil care: use as part of seasonal conditioning to support resilience and moisture balance.

How to use

• Distribute evenly over the target area or mix into the growing medium.
• Water after application to help distribution and settling.
• Reapply as part of routine soil management or substrate preparation.

Note: Real-world results vary with soil type, climate, and ongoing care. This product is a soil amendment designed to complement fertility programs.
