Calcium occupies the fourth place in order of importance of the most necessary elements for plants, just behind the macroelements such as Nitrogen Phosphorus and Potassium, already known to all professionals and crop enthusiasts.

The biological fertilizer and calcium concentrate Calgreen de Metrop, by its formulation, is a unique product. The main base is a certain concentration of hydrogen and calcium that any plant requires for the production of the membrane or cell wall, causing in it, a greater density and thickness and therefore a greater consistency and strength.

This greater hardness and consistency of the membrane in the cells, provides 80% additional protection against most fungi, as well as greater resistance against microbial diseases.

Calcium added to any culture medium, be it soil, coconut as well as in hydro or aeroponic systems facilitates the release of ions from colloidal particles of other nutritional elements, which in turn increases the absorption capacity of those others nutrients to the plant.

Caltrop Calcreen concentrated fertilizer from Metrop, is manufactured from the highest quality raw materials and can be mixed with any other Metrop product.

With the Metrop MR 1, MR 2 and Calgreen fertilizers the farmer has a complete range of top quality fertilizers that allow the plant to develop, on any type of medium, healthier roots, flowers and fruits of the greatest possible size, ensuring maximum productivity crops.

The concentrated biological fertilizer Calgreen de Metrop, is produced from plants, by means of a high quality extraction and contains all the macro and micronutrients necessary for growth and full flowering on any culture medium.

• It significantly improves the absorption of nutrients through the root.

• Guarantees a strengthening and hardening of the palpable buds.

• Ensures an increase in weight of the final product.

• Guarantees the presence of magnesium in sufficient quantity for the correct synthesis of chlorophyll and proteins.

• The product does not contain dyes and is not diluted in water. It only contains pure raw materials.

• Given its high concentration and degree of purity, we recommend the use of low EC levels as well as EC (Electro conductivity) meters to avoid over-fertilization.

• The product does not expire, nor does it have an expiration date.
