The new generation of plant fertilizers

The new generation of highly concentrated liquid plant nutrition from Metrop biominerals can also rightly be called a new generation of plant nutrition.

The Metrop biomineral plant nutrients are so strongly filled with NPK's and micro elements that the fertilizer looks like a green yogurt.

The fertilizer is so good that it is suitable for all mediums.

The products are so concentrated that you need 5 to 10 times less fertilizer than normal.


The Metrop MR1 is the growth fertilizer and is a NPK 10-40-20 + micro elements.

The root is the base. Phosphorus is the main building block for the roots and a high Phosphorus fertilizer with 40% Phosphorus is the best fertilizer for root growth. But that only works if the level Potash is much lower compare to Phosphorus.


The Metrop MR2 is the flower fertilizer and is an NPK 10-20-40 + micro-elements.

A 40% high Potash fertilizer means big buds!!
A basic rule is that anything in the plant that needs to be thickened give as much Potash as possible. But it is important that at the same time the phosphorus content in the fertilizer is much lower.

You get the maximum thickness of a bud when the Potash is twice the amount of phosphorus.

Only 10ml to 10 liters of water maximum is used with this bloom nutrients.


The Metrop Calgreen is the Calcium Nitrate fertilizer.

Calcium is the 4th most important nutrient for a plant. And much too little present in many regular plant nutrients.
Calcium is very important in the medium because it brings many nutrients within reach of the plants by displacing ions.

In addition, Calcium promotes the decomposition of organic substances, which also makes many nourishing nutrients available. The yields of a crop will therefore increase sharply after adding Calcium.

Calcium is also binding acids that would poison the plant body, including the oxalic acid.

Calcium Nitrate in a certain compound (protein) is the most important building block for the plant cell wall. Because Calcium Nitrate strengthens the plant cells with the help of Boron (become vitamin B12), this results in a stronger plant with less chance of mould and rot and a heavier final yield.

Metrop Calgreen is a unique biomineral product that contains Calcium Nitrate Protein in a very high concentration together with Boron, Magnesium and other trace elements.

An absolute weight and strength builder.

Only 4ml to 10 liters of water maximum is used with this nutrition.


To make such a strong plant food, one must use the highest quality raw materials. And you can taste that in the taste!

The micro elements are also present in a high concentration because they are very important for various controls in the plant.

To use is to see. And seeing is believing.

With a liquid NPK high Phosphorus fertilizer and a high Potash fertilizer in combination with a high liquid calcium nitrate fertilizer, your crop will be strongest.
