Metrop Calgreen is a highly concentrated nutritional supplement based on calcium and magnesium, two fundamental elements for plant health and vigour. Calcium plays a structural role in building cell walls, while magnesium is a central component of chlorophyll, indispensable for photosynthesis.

Calcium deficiency manifests as burnt leaf edges, deformation of new shoots, and increased fragility of stems. Magnesium deficiency causes interveinal yellowing (chlorosis), starting from the oldest leaves. Calgreen corrects both deficiencies quickly and effectively.

Its concentrated liquid formula (1 L for 250 to 500 L of water) ensures immediate dissolution and optimal absorption by the roots. Compatible with all growing systems (hydroponics, aeroponics, substrates), it can be used preventively or curatively according to plant needs.

Ideal during all growth phases, Calgreen helps strengthen plant structure, improve resistance to environmental stress, and optimise chlorophyll production for better harvests.
