FoxFarm Cal-Mag (1 gal)

Gringo Rasta® Cal-Mag from FoxFarm is designed to support strong plant structure and healthy yields by supplying two essential secondary nutrients—calcium and magnesium. These minerals play a vital role in strengthening cell walls, aiding in enzyme activity, and supporting fruit and flower development for a more productive garden.

Ideal for use in both soil-based and hydroponic systems, Cal-Mag helps prevent common nutrient deficiencies that can lead to issues like blossom end rot or poor bud formation. Its formula is OMRI Listed® and registered as a CDFA Organic Input Material, ensuring it’s suitable for certified organic growing. Containing 3% calcium and 0.9% magnesium, it’s derived from calcium carbonate, magnesium sulfate, and soy protein hydrolysate for efficient nutrient uptake.

Whether you’re growing vegetables, fruits, or flowering plants, this supplement can be a valuable part of your feeding program to promote overall plant vigor and resilience.
