Metrop
When nutrient concentration for plants takes centre stage, the Dutch manufacturer of biomineral liquid fertilisers offers an exceptionally high proportion of key nutrients for universal use, whether you are growing in soil, coco or in hydroponics.
Metrop fertilisers therefore dispel the myth that every growing medium necessarily requires a different fertiliser. If you use Metrop, you only need to adjust the dosage. Would you like to learn more about highly concentrated nutrition from their own laboratories? Then read on!
As we have already explained, Metrop does not make much distinction between substrates and individual cultivation methods. The unique products are developed in the Netherlands so as to satisfy commercial growers as much as possible, for whom the difference in yields is a matter of livelihood, while also being easily accessible to complete beginners, for whom they will make the entire plant growing process much easier.
The company prides itself on intensive research in its own laboratories. It refuses to adopt information about findings in the field of plant cultivation indoors or outdoors. For several years now, it has followed a path based exclusively on its own experience. Every two weeks, a laboratory analysis of the tested plants is carried out.
If, from a grower’s perspective, you have been considering for some time that you would like to test fertilisers other than those you are used to, or simply want to try something new, the comprehensive Metrop range has its own specific features that are worth exploring.

INCREDIBLY UNIVERSAL NUTRITION FOR ALL TYPES OF PLANTS
The Metrop brand is represented in our shop by 7 unique products, which we will now introduce in more detail. Their creation is the result of demanding technological processes, especially biosynthesis, which we will also explain.
- MR1 – a biomineral fertiliser for the vegetative phase of plants, characterised by NPK values of NPK 10-40-20 and containing all macro- and microelements that a plant needs for vigorous growth, regardless of the type of substrate. We recommend it from the second day of growth until the third or even fourth week of flower formation. In addition to the basic nutrients, the composition is enriched with magnesium and chelated trace elements. Chelation is known for being completely natural to plants, which significantly increases the bioavailability of the nutrients contained.
- MR2 – a biomineral fertiliser designed for maximum yield and huge flowers! Its pure composition allows every grower to maximise yields without the risk of overfertilisation. If you are involved in hydroponics, you will appreciate that the quality of the substances is so high that it does not allow deposits to form in hydroponic systems. This again improves fertiliser management and the service life of hydroponic equipment. We recommend following MR1 with this fertiliser, meaning applying it three, or possibly four, weeks from the moment the plant begins to flower.
- Calgreen - a unique product containing amino acids and vitamins, developed on the basis of a synergistic combination of calcium and nitrogen. These two elements are also the basic building blocks of plant cell walls. The effect of this product is such that the resulting inflorescence is heavier, holds together beautifully as a whole, and the plants are significantly stronger and more flexible. The Dutch manufacturer also declares an 80% success rate in preventing rot and mould.
- Root+ - a root stimulator that completely departs from conventional products, containing high-quality amino acids and vitamins. An interesting fact that will please every grower is that, thanks to its own biosynthesis, Metrop is able to define precisely the type and number of individual amino acids in the composition of this product. The Root+ root booster thus gains a kind of extension, because in addition to the roots and rootlets themselves, it also directly stimulates the leaves and stems and affects the formation of important enzymes. The structure of amino acids resembles a spiral that can be measured. The value above which the plant is no longer able to absorb amino acids is stated as 1500 DA (Daltons). It is therefore striking that most organic products commonly available on the market have these values at around 10,000 DA. In the case of Metrop Root+, the length of this amino spiral is only 700 DA! You will notice the difference most on plants exposed to stress.
- AminoXtrem - a flower stimulator. When we first saw the presentation of this broad-spectrum amino acid-based product, we were amazed. Its application affects, quite literally, all processes in all types of plants that you can think of. Both the visible ones and those hidden from the human eye. AminoXtrem has a beneficial effect on roots, stems, leaves and flowers, and again uses controlled biosynthesis of amino acids, the advantages of which we described above. In laboratory conditions, amino acids are obtained by fermentation, hydrolysis, or precisely through biosynthesis, which surpasses the other methods in that the resulting product is able to influence more parts of the plant at once. Amino spirals created by biosynthesis measure less than 700 Daltons, and therefore are much better actually utilised by the plant than is the case with ordinary amino acid-based stimulators. Biosynthesis is a technologically very complex process, and Metrop is one of the few companies to have invested both time and resources in it, thanks to which it is now collecting awards and gaining renown in the world of growing.
- MAM – special nutrition for mother plants is enriched with micro- and macroelements that would otherwise be lacking due to the frequent taking of cuttings. The increased phosphorus content ensures continuous growth of roots. Magnesium, in turn, takes care of chlorophyll production and protein synthesis.
- Enzymes - When we are talking about proteins, we must not forget the last supplement from the Metrop range, which is this bottle packed with special protein molecules that accelerate a whole range of biochemical processes taking place in the plant body.
If the Metrop brand has caught your attention as it has ours, take advantage of the discounted prices and, above all, the synergistic action of the individual products we have just introduced, namely in the form of comprehensive sets. Before that, however, please do not hesitate to ask us anything. Call or write to the well-known address info@higarden.cz.
