Hy-Pro Cal-Mag 1 L (Calcium & Magnesium)

Our main goal when we grow plants, whether in a garden or in a hydroponic system, is to help them thrive and create high yields. Calcium and magnesium are two of the most important secondary macronutrients that are vital for healthy plants. Used in relatively large quantities by plants and therefore important to supplement your plants regularly. These minerals, together with the micronutrients, also contribute to the ionic balance of the plant. Hy-Pro Cal-Mag is great for improving soil plant health and is an essential ingredient for hydroponic nutrient management.

Hy-Pro Cal-Mag provides a precise balance and optimal ratios of calcium, magnesium and iron that are crucial during all growth phases, especially in heavily fruiting plants and fast-flowering annuals. The high content of calcium and magnesium in our formula improves the strength of cell walls and the production of chlorophyll. Hy-Pro Cal-Mag is vital for soft water areas where tap water contains little or no calcium or magnesium. Hy-Pro Cal-Mag is also fortified with a proprietary blend of select trace minerals to maximize yields of fruiting and flowering plant species. Iron, for example, acts as a catalyst for essential reactions in the plant, especially related to metabolism. It must be the correct form of chelated iron. And it must be in the right proportions, in relation to the other nutrients in your reservoir.

HY-PRO Cal-Mag fertilizers are not only supplements for soil plants, but they are also crucial for thriving coconut crops and hydroponic gardens.


Magnesium forms the core of the chlorophyll molecule and is therefore essential for photosynthesis. This makes it an indispensable element for plant development. Magnesium promotes the absorption and transport of phosphorus. It contributes to the storage of sugars in the plant. Magnesium performs the function of an enzyme activator and in fact activates more enzymes than any other nutrient. Magnesium is also used by plants for carbohydrate metabolism and cell membrane stabilization. Magnesium deficiencies result in weak stems, loss of greenness in the oldest leaves and the appearance of yellow and brown spots, even though the leaf veins remain green.


Calcium is an essential element required for plant growth and development under both non-stressed and stressed conditions. It fulfills a dual function, because it is not only an important factor for cell wall and membrane stability, but also serves as a second messenger in many developmental and physiological processes, including the response of plants to biotic stress. Calcium adheres to the walls of plant tissues, stabilizes the cell wall and promotes cell wall formation. Calcium is also involved in cell growth and development. It neutralizes toxins in plants and contributes to seed formation. A calcium deficiency causes yellow and brown spots on the leaves. It also slows down plant growth in general.


-When using your substrate repeatedly, always use Hy-pro Cal-Mag
-Mix 2.5 ml per 1 liter of water during growth and flowering.
-Suitable for all plants - both indoors and outdoors.
