About This

• TRANSFORM HEAVY CLAY SOIL: Solution grade powder instantly starts loosening compacted ground to improve drainage and aeration. This pH-neutral soil conditioner allows roots to penetrate deeper without altering soil chemistry.
• SOLUTION GRADE PURITY: Contains 97% calcium sulfate dihydrate with 22.5% calcium and 18% sulfur. Fine professional-grade powder absorbs faster than chunky pellets - ideal for quick soil improvement and fertigation systems.
• STOP BLOSSOM END ROT: The ultimate calcium boost for tomatoes, peppers, and fruit trees. Strengthens plant cell walls, enhances nutrient transport, and prevents common calcium deficiencies that reduce crop yield.
• REPAIR SALT-DAMAGED YARDS: Effectively flushes excess sodium caused by winter de-icing, heavy fertilizers, or irrigation water. Reduces aluminum toxicity and creates a thriving environment for earthworms and beneficial microbes.
• pH NEUTRAL ADVANTAGE: Unlike agricultural lime, gypsum adds calcium WITHOUT raising soil pH. Safe for alkaline soils, acid-loving plants like blueberries, and any garden where pH balance matters.
• FAST-ACTING FORMULA: Fine powder dissolves and penetrates soil faster than pelletized gypsum. See drainage improvement in weeks, not months. Works immediately upon watering in.
• MUSHROOM CULTIVATION READY: Professional-grade calcium sulfate improves substrate structure and water-holding capacity. Provides essential calcium for healthy mycelium development and increases yields in oyster, shiitake, and specialty mushrooms.
• LAWN RENOVATION ESSENTIAL: Breaks up compacted turf, improves water infiltration, and reduces surface crusting. Apply after aeration for maximum penetration. Safe for all grass types including bermuda, fescue, and st. augustine.
• COMMERCIAL & HOME USE: Trusted by professional farmers, greenhouse growers, and landscapers. Same solution grade formula scales from backyard vegetable beds to multi-acre agricultural operations.
• TRUSTED QUALITY SINCE 1989: CDFA-registered and manufactured in California. Lab tested for purity and heavy metals. Family-owned Greenway Biotech has served growers for over 35 years.
