CAL58-Micronized Calcium Sulfate Powder ORGANIC

CAL58 is an ultra-micronized, high-quality Calcium Sulfate (CaSO4) from mined gypsum sources free of magnesium and heavy metals.  Each gram/gal of CAL58 provides 58 ppms of Ca to the plant.  

The tiny particle size permits the plant to pick up micronized rocks that enter through the Stoma (leaf pore) or roots directly in the water solution.  Recommended dosages are 1 to 2 grams/gallon for both soil and foliar feeds.
