Metrop GreenXtrem 1 Litre – Next-Generation Phytohormone Root and Vitality Stimulator
If you know Metrop RhizoXtrem, you know the results. Metrop GreenXtrem is its direct successor — same proven formulation, broader positioning, new name. A 100% plant-derived marine algae concentrate that combines root stimulation, immune system activation and rhizosphere antisepsis in a single ultra-concentrated product.

Active Compound Profile
Classified as an organic fertiliser with an NPK of 0.3-0.03-0.4, GreenXtrem's value lies not in mineral nutrition but in its biostimulant compounds:
- Auxin + cytokinin: natural phytohormones from seaweed that control root initiation, cell division and lateral shoot development at the meristematic level.
- Laminarin (0.4%): a β-1,3-glucan polysaccharide from Laminaria species that triggers systemic acquired resistance (SAR) pathways in the plant.
- Mannitol (0.7%): sugar alcohol providing osmotic regulation and a readily mobilisable energy reserve.
- Iodine + trace elements: natural antiseptic effect in the rhizosphere, reducing fungal and bacterial infection risk.
From RhizoXtrem to GreenXtrem: What Changed?
The formulation is unchanged — the rebranding reflects the product's broader application profile. While RhizoXtrem was positioned primarily as a root stimulator, GreenXtrem acknowledges what experienced growers already knew: the phytohormone complex benefits the entire plant, from root architecture through stem strength to foliage vitality. The dosage protocol remains identical: 0.3 ml/L from first true leaves through to early bloom.
Feed Schedule Integration
Apply GreenXtrem from the emergence of the first true leaves, combining with Metrop MR1 for vegetative base nutrition. Target pH 5.4–5.8 with starting EC of 0.4. Transition to Metrop AminoXtrem when entering the bloom phase. At 0.3 ml/L, one litre produces over 3,300 litres of feed solution — the highest yield-per-bottle ratio in the Metrop Additive range. For stressed or diseased plants, continue application at standard dose until full recovery.

Is Metrop GreenXtrem the same as RhizoXtrem?
GreenXtrem is the direct successor to RhizoXtrem with an identical formulation. The composition — phytohormones, laminarin, mannitol, trace elements — remains unchanged. The rebrand reflects the product's broader application as a complete vitality booster rather than solely a root stimulator. Dosage and application protocols are the same.
When should I switch from GreenXtrem to AminoXtrem?
GreenXtrem is applied from first true leaves through to the start of the bloom phase. AminoXtrem begins at week 4 and continues through the final week. In the standard Metrop schedule, they briefly overlap: GreenXtrem builds the root foundation, AminoXtrem takes over bloom-phase biostimulation.
Does GreenXtrem need to be applied at every watering?
Application at every watering is not required. Many growers alternate between a GreenXtrem feed and a plain water feed. This alternating schedule provides sufficient hormonal stimulation without overdose risk. For stressed or diseased plant treatment, continuous application at the standard 0.3 ml/L dose is recommended until full recovery.
How many litres of nutrient solution does GreenXtrem 1 litre produce?
At the recommended 0.3 ml/L, one litre produces over 3,300 litres of feed solution. With an alternating application schedule, effective coverage extends even further. This concentration makes GreenXtrem one of the most cost-effective root and vitality stimulators available in the professional segment.
