The higher the phosphorus content in a growth fertilizer, the bigger the root growth!
And roots are the foundation for a good harvest.
For this reason, Metrop developed the MR1 liquid growth fertilizer. Metrop MR1 contains an NPK of 10-40-20 along with many additional micronutrients and magnesium.
In Metrop MR1 Grow Fertilizer, the balance between NPK and micronutrients is specifically formulated to achieve maximum root growth.
Growers often use root stimulators for their plants. However, a root stimulator won’t do much if not applied alongside an NPK fertilizer or a fertilizer with low phosphorus.
Using Metrop MR1 together with the Metrop Root+ Plant Root Stimulator gives growing plants large roots.
The raw materials in Metrop MR1 liquid growth fertilizer are of very high purity, allowing a high NPK content without losing product stability.
The quality of the raw materials ensures that the mixture will never clog tanks or irrigation systems. Once mixed with water, the EC remains stable.
Micronutrients are also added in higher and purer concentrations, allowing faster and better photosynthesis and improving the final product quality.
MR1 ensures sufficient phosphorus for explosive root growth and enough magnesium for optimal chlorophyll and protein synthesis.

Metrop MR1 is a highly concentrated liquid growth fertilizer.
The maximum use is 100 ml in a 100-liter water tank, eliminating the need to carry large bottles.
1 liter of Metrop liquid growth fertilizer equals 5 to 10 liters of most other brands.
Why buy water when real concentrated liquid fertilizer exists?
Metrop MR1 Grow Fertilizer contains no harmful dyes and is biodegradable.
We recommend using Metrop MR1 together with Metrop Root+ and Metrop Calgreen for maximum plant growth.
