Gringo Rasta® Cal-Mag from FoxFarm is a concentrated nutrient supplement that delivers two essential minerals—calcium and magnesium—to promote strong, healthy plant growth. These nutrients are critical for cell wall development, enzyme activity, and the production of abundant fruits and flowers.
This convenient 1-quart size is perfect for smaller gardens, container plants, or indoor growing setups where precise nutrient management is essential. Cal-Mag helps correct and prevent common deficiencies that can cause issues like weak stems, blossom end rot, or reduced flower quality. The formula is OMRI Listed® and CDFA Organic Input Material approved, making it suitable for certified organic production. Containing 3% calcium and 0.9% magnesium, it’s derived from calcium carbonate, magnesium sulfate, and soy protein hydrolysate for effective absorption.
Whether you’re feeding vegetables, herbs, fruiting plants, or ornamentals, this nutrient boost supports overall plant vigor and improves your harvest quality.
