NPK according to, your online horticultural adviser

Growshops .fr presents you in its vast online catalog, fertilizers based on NPK, in liquid or powder forms, available in its department: Fertilizers Hydro Coco Earth.

These three initials, NPK, represent macro-nutrients, primary nutrients, necessary for the evolution of all plants, to be added to other secondary nutrients, micronutrients (magnesium, calcium, iron, manganese, boron, zinc, sulfur, copper, cobalt, molybdenum,...).

NPKs arenitrogen (N), phosphorus (P) and potassium (K).


The NPK are the major chemical molecules composing essentially the basic fertilizers but also numerous additives, stimulators admissible within a fertilization program.

From there, various formulas of NPK are specifically studied, balanced to meet the nutritional needs of plants.

The NPK ratios proposed vary according to the stage of the crop and the grower's objective.

On, you can discover recognized brands producing quality fertilizers, rich in NPK, such as Biobizz, Plagron general Hydroponics, General Organics, Platinium Nutrients, Atami, Vaalserberg Garden (VG), HydroPassion, The Growth Technology , 420 Hydroponics, 420 Organics, Canna, Grotek bioTabs, The Rambridge , Aptus Holland, Hesi...

What functions do NPKs have on plants, according to

azote N ...

N for nitrogenium, nitrogen is a chemical molecule that ensures the growth of plants, intervening in the production of proteins and thus directly influencing the metabolism of the plant.

Nitrogen(N) also plays an essential role in the constitution of the chlorophyll of the plants which then makes it possible to carry out the photosynthesis vital to the plant.

phosphore P ... Phosphorus(P) stimulates plants to develop healthier roots, more vivacious in the occupation of the substrate.

In addition to this beneficial stimulation of the root system, phosphorus (P) encourages more abundant flowering and fruiting.

potassium K ...

Finally, the last of the three major macronutrients, potassium(K) guarantees a better circulation of water and nutrients, and a progressive release of its two sources of energy, throughout the plant, from the roots to the tops.

Potassium (K) also strengthens the walls of the molecules to make them more resistant

In this way, this essential macronutrient strengthens the immune system of plants to naturally fight against potential attacks from pests, diseases or molds.

What are the ratios of NPK needed for growth and flowering?

The proportions of macronutrients differ depending on the stage of cultivation in which the plants are located. Indeed, NPK concentrations evolve from growth to flowering.

In general, during the vegetative phase, there is a major proportion ofnitrogen (N ) in growth fertilizers and other additives (or stimulators) to meet the primary needs of plants during this stage.

Therefore, the ratios of phosphorus (P) and potassium (K) are lower than for the first macronutrient.

Conversely, these same proportions are reversed during flowering or fruiting of the plants.

Thus, basic fertilizers and other boosters dedicated to flowering have higher proportions of phosphorus (P) and potassium (K) than nitrogen (N), which is largely reduced or even non-existent in some stimulators.

Because during this phase, it is necessary to maintain the chlorophyll of the plants by means of nitrogen (N) but an excess of this last macronutrient would generate a fall of the productivity, a weak development of the flowers or the fruits., your online horticultural advisor
