Description
Balanced Calcium & Magnesium Nutrition for Stronger Plants and Cleaner Root Zones
RAW Calcium/Mag is a premium nutrient supplement delivering 15% Calcium and 3% Magnesium in a fully water-soluble formula designed to support strong plant structure, efficient nutrient transport, and optimal photosynthesis.
Calcium and magnesium deficiencies are among the most common challenges in intensive cultivation, especially in hydroponic, coco, and high-performance soil systems. RAW Calcium/Mag addresses both nutrients simultaneously using a precise blend of calcium nitrate and magnesium sulfate, helping plants maintain healthy growth and nutrient balance.
Calcium strengthens cell walls and supports root development, while magnesium plays a critical role in chlorophyll production and plant energy metabolism. Together, these nutrients promote vigorous growth and consistent plant performance throughout the entire lifecycle.
An added benefit of this formulation is the inclusion of clean nitrate nitrogen, which helps improve nutrient uptake synergy without overloading the plant. This small amount supports efficient nutrient movement while remaining safe during bloom without promoting unwanted stretch.
With its optimized 15:3 calcium-to-magnesium ratio, RAW Calcium/Mag helps prevent nutrient lockouts and maintains a clean, efficient root zone.
This concentrated formula dissolves completely in water, making it ideal for soil, hydroponic, and fertigation systems where precise nutrient control is essential.
