Green Planet Pro Cal is a concentrated calcium-magnesium supplement designed to strengthen plant structure, optimise nutrient uptake, and prevent deficiencies throughout the entire growth cycle. Containing fully chelated calcium, magnesium, iron, and a range of essential trace elements, Pro Cal plays a vital role in supporting enzymatic functions, chlorophyll production, and robust root development. This makes it particularly beneficial in coco coir systems, where additional supplementation of calcium and magnesium is often required to maintain balance and prevent lockouts.
Calcium fortifies plant cell walls, helping to build stronger stems and a more resilient structure, while magnesium serves as a key component in chlorophyll, driving efficient photosynthesis and lush, green growth. Iron and other micronutrients enhance metabolic processes and prevent common deficiency symptoms such as interveinal chlorosis and stunted development. By delivering these minerals in chelated, plant-available forms, Pro Cal ensures rapid uptake and consistent performance, even in fast-growing, nutrient-hungry crops.
Suitable for soil, coco, and hydroponic systems, Pro Cal is a versatile additive that integrates seamlessly with any nutrient program. Its high solubility and clean formulation allow for precise application, making it a trusted choice for both hobbyists and professional growers seeking stronger plants, healthier foliage, and improved yields.
