Metrop is a company that specializes in high-quality liquid plant foods for agriculture, horticulture and hobby cultivation.

Metrop: The Most Concentrated Liquid Plant Nutrition Available

Metrop operates on a fundamentally different principle to most nutrient manufacturers. Based in IJsselstein, the Netherlands, this company has spent over 25 years developing biomineral concentrated liquid fertilisers that achieve NPK ratios competitors cannot replicate. The result: a dosage rate of just 10 ml per 10 litres of water delivering complete nutrition across all growth stages. At Plant and Flower, access the Metrop range within our nutrients selection. Order before 2 PM for next-day delivery via Bpost across Belgium and the Benelux.

SAP Analysis-Driven Development

Metrop develops its formulations through plant sap analysis conducted every two weeks during growth and flowering cycles. This methodology identifies precisely which nutrients plants can absorb most effectively at each developmental stage, eliminating guesswork from formulation. The raw materials selected are cadmium-free, contain virtually no chlorine, and carry no heavy metal contamination. These premium inputs enable the extreme NPK differentials that define Metrop products — resulting in concentrations up to ten times higher than standard liquid fertilisers. All products are fully biodegradable and compatible with foliar application.

The Metrop Product System

Metrop keeps its product line deliberately concise, with each component serving a specific function:

  • MR1 (NPK 10-40-20): vegetative growth nutrient with high phosphorus content driving explosive root development and robust plant architecture.
  • MR2 (NPK 10-20-40): flowering nutrient maximising potassium for dense, heavy flower and fruit production.
  • Calgreen: calcium protein formula with boron and magnesium strengthening cell walls and preventing rot.
  • AminoXtrem: amino acid-based stimulant boosting plant vitality, stress resistance, and foliar nutrient uptake.

Frequently Asked Questions About Metrop

What is the delivery time for Metrop products in Belgium?

Plant and Flower dispatches Metrop orders within 24 hours when placed before 2 PM. We ship via Bpost to all addresses in Belgium and the wider Benelux region. A tracking code is provided as soon as your parcel leaves our warehouse.

Why is Metrop significantly more concentrated than competing brands?

Metrop uses higher-grade raw materials that enable larger NPK differentials than standard fertiliser inputs allow. This produces concentrations up to ten times higher than conventional liquid nutrients. At just 10 ml per 10 litres of water, the cost per feeding solution is substantially lower despite the premium positioning.

Is Metrop suitable for hydroponic systems?

Yes, all Metrop products work across every growing medium including soil, coco, rockwool, DWC, NFT, and aeroponics. Metrop provides dedicated feeding schedules for each system type. The brand philosophy is that plants require the same building blocks regardless of medium — only dosage needs adjustment.
