Plagron - CalMag Pro

Additional fertilizer with calcium & magnesium for strong plants

Plagron CalMag Pro is a high-quality fertilizer supplement specially formulated to reliably supply plants with calcium (Ca) and magnesium (Mg) . These two essential elements are crucial for the formation of stable cell walls, chlorophyll production, and healthy plant development.

CalMag Pro is especially indispensable when using soft water, reverse osmosis water, or rainwater , as these water sources often contain too little calcium and magnesium. With CalMag Pro, you can reliably prevent deficiency symptoms such as leaf discoloration, growth disorders, or weak stems.
