This supplement provides a perfect ratio of calcium (Ca) and magnesium (Mg), avoiding competition between the two elements and ensuring efficient absorption. Thanks to its sulfate-free formula, CalMag Pro is completely stable and compatible with other nutrients, allowing you to mix with confidence without altering the balance of the nutrient water.

If you grow with LED lights, CalMag Pro becomes indispensable. These lights reduce plant transpiration, which limits the ability to absorb calcium and magnesium. This additive compensates for this loss and keeps your plants strong, structured, and with optimal absorption at all times.

Its action doesn't stop there: CalMag Pro strengthens cell walls, improves the plant's natural resistance to environmental stress, and stimulates the development of young roots. By strengthening root hairs, the uptake of essential nutrients for vigorous growth is also optimized.

Versatile, efficient, and easy to apply, Plagron CalMag Pro is the foundation every professional grower needs to ensure nutritional stability in demanding conditions. Don't let water quality limit your crop: it balances, strengthens, and stimulates from the first watering.
