Metrop develops, produces and supplies biomineral concentrated liquid fertilizers, fertilizer suspension, leaf fertilizer, plant health promoters & more. The majority of the Metrop’s products line are suitable as leaf nutrition.

Through years and years of extensive cultivation and testing experience, Metrop Hydroponics approaches crops in a different way than most other food producers. The main idea is to give a crop what it can absorb the most at every stage of the growth and flowering cycle.

Metrop continuously strives to bring growers the most effective products on the market. Metrop thereby focuses most on mineral trace elements, enzyme processes and the health effect on plants and people.

Metrop products are developed and improved through a nutrient analysis of the plant juice every 2 weeks in both growth and flowering cycle (S.A.P. Analysis). This is the only way to make the best plant fertilizer!

We use different raw materials for our products than other plant food suppliers, which enables us to make larger NPK differences, resulting in better, stronger and larger crop development. For the grower and consumer, this means a healthier end product with a better taste and smell.

Below you will find the products in our Main Line.


Metrop MR1
Metrop Grow fertilizer MR1

10-40-20 NPK fertilizer

Metrop MR1 grow fertilizer is a high quality plant extract with all macro and micro nutrients that are necessary for growth and pre-flower on any medium.

With the Metrop biomineral MR1 fertilizer for the growth period, the NPK and micro-element balance are specially formulated for the highest possible crop yield.

The raw materials used in Metrop MR1 grow fertilizer are of very high purity, which makes it possible to achieve a high NPK proportion, without disturbing the plant.

The quality of the raw materials ensures that MR1 will never clog the irrigation system or tank. Once prepared with water, EC will remain stable.

The micro elements are also added in a higher and purer degree, enabling the plants to have a faster and better photosynthesis, which is beneficial for the quality of the end product.

  • Assures the availability of sufficient potassium for the start of bloom andplant robustness.
  • Assures the availability of sufficient phosphorus explosive root development
  • Assures the availability of sufficient magnesium for optimum chlorophyll and protein synthesis
  • Doesn’t contain any harmful colouring agents and isn’t diluted with water. Consists ony of the purest raw materials.
  • Therefore use with low EC


Metrop MR2
Metrop Flower fertilizer MR2

10-20-40 NPK fertilizer

Metrop MR2 grow fertilizer is a high quality plant extract with all macro and micro nutrients that are necessary for full top bloom on any medium.

The more potassium to a fruit or flower, the fatter the fruit or flower will get. For the largest possible volume increase, twice the potassium than phosphorus!

The NPK and micro-elements balance used in Metrop MR2 flower fertlizer, is espcially composed to produce the possible yield from the plant.

The raw materials in Metrop MR2 bloom fertilizer are of very high purity, enabling it to achieve a high NPK prportion without disturbing the plant.

The quality of the raw materials ensures that MR2 will never clog the irrigation system or tank. Once prepared with water, EC will remain stable.

The micro elements are also added in a higher and purer degree, enabling the plants to have a faster and better photosynthesis, which is beneficial for the quality of the end product.

  • Visibly improves plant top condition
  • Assures the availability of sufficient potassium to allow tops to reach their full growth
  • Assures the availability of sufficient phosphorus for continuous growth of the roots
  • Assures the availability of sufficient magnesium for optimum chlorophyll and protein synthesis
  • Is adapted to optimum bloom explosium
  • Doesn’t contain any harmful colouring agents and isn’t diluted with water. Consists ony of the purest raw materials.
  • Therefore use with low EC

Metrop Calgreen
Metrop Calgreen

Calcium Magnesium fertilizer, 22.5% Ca

Metrop Calgreen is a unique product. The basis of the product is Nitrogen, Calcium and Magnesium in a specific compound. This compound is a building block for the plant cell walls, resulting in a compact heavier fruit and plant.

In addition, Metrop Calgreen provides 80% protection against most molds and rot diseases.

Extra Calcium in the medium ensures that ions of other nutritional elements are released more easily from the colloidal particles. The plant therefore has more nutritional building blocks available.

Metrop Calgreen is produced from very high quality raw materials and can be mixed with any Metrop fertilizer product.

With Metrop MR1, MR2 and Calgreen, the grower has a top plant fertilizer line at hand that, on any medium, enables the plants to build up the largest possible root system and tops for the highest possible yield.

  • Visibly improves absorption of nutrients at the roots
  • Assures tangible strengthening and toughening of the tops
  • Assures a measurable increase of end product mass
  • res the availability of sufficient magnesium for optimum chlorophyll and protein synthesis
  • Doesn’t contain any harmful colouring agents and isn’t diluted with water. Consists ony of the purest raw materials.
  • Therefore use with low EC

Metrop Root+
Metrop Root+

Biological root stimulator ang grow stimulator

Metrop Root+ root stimulator and plant growth stimulator is a high-quality plant extract containing all amino acids and vitamins necessary for maximum growth of roots and plant in any medium.

Metrop ROOT+ root stimulator is made of enzymes from the Transferase, Oxidoreductase and Ligase groups. This means that trunk and root growth are not only catalyzed by a faster ion transfer, but also by faster moving and linking minerals to organic building blocks.

ROOT+ increases mineral intake and promotes bioavailability of minerals such as zinc, calcium, iron and magnesium. Enzymes are essential for all functions and every cell needs around 100.000 units for its metabolic processes.

This product gives you better growth, more intense color and more resistant plants.

Metrop Root+ organic root stimulator is a high quality extract containing all enzymes and coenzymes needed for root growth in any medium.

  • Stimulates explosice root development
  • Stimulates the production of hair roots
  • Increases resistance to diseases
  • Increases resistance to stress
  • Accelerates the metabolism in the plant

Metrop AminoXtrem
Metrop AminoXtrem

Flower stimulator and plant stimulator

Metrop AminoXtrem flower stimulator / bloom stimulator is a very high-quality amino-acid and vitamin booster that makes sure that the stem, leaves, tops and all other visible and non-visible growth and bloom functions can function at their best.

Because these amino acids were produced by biosynthesis, it was possible for Metrop to determine by itself how much and which amino acids are present.

This means that Metrop AminoXtrem does not only facilitate formation of the top, but also stimulates certain hormones and the formation of leaves.

Producing amino acids by biosynthesis ensures that an amino helix is just 700 DA long, in contrast to the 10.000 DA of any other organic product. Plant cells can absorb a helix with a length not exceeding 1500 DA.

This means that Metrop AminoXtrem acts very fast and has a noticeable effect especially on stressed plants, which can clearly be seen, for example from the leaves.

The Metrop AminoXtrem plant and bloom stimulator is a high quality plant extract with all amino acids and vitamins needed for explosive growth and top flowering in any medium.

  • Explosively stimulates top formation
  • Lets Flowers live longer
  • Increases resistance to diseases
  • Increases resistance to stress
  • Restore stressed plants
  • Stimulates the production of hormones
  • Stimulates the production of enzymes
  • Immediately absorbable without the intervention of enzymes
