Metrop MAM 250 ml
Metrop MAM 250 ml is a specialised biomineral fertiliser for mother plants and clones with NPK 20-20-8. It contains 18.7% Kelpak seaweed extract that stimulates root development and increases stress resistance. Mother plants subjected to regular cutting weaken over time — MAM is engineered to counteract this decline by providing targeted nutrition for continuous regeneration. At 0.5 ml per litre, this 250 ml bottle suits growers maintaining a few mother plants or trialling the Metrop mother plant programme. Visible results within two weeks. Fast delivery from Belgium.
Metrop MAM 250 ml – Biomineral Mother Plant Fertiliser NPK 20-20-8 with Seaweed Extract
Mother plants are the foundation of any clone-based operation. Their health directly determines cutting quality, rooting speed, and downstream vigour. Metrop MAM is formulated specifically for plants that remain in perpetual vegetative growth while enduring repeated cutting stress — a nutritional profile that standard growth fertilisers cannot match. With NPK 20-20-8 and 18.7% Kelpak seaweed extract, MAM delivers both mineral nutrition and organic biostimulation. Explore the full Metrop range at Plant and Flower.
The Kelpak Advantage
Kelpak is derived from a specific seaweed variety with documented effects on root development and stress recovery. In the context of mother plant maintenance, its benefits are measurable:
- Accelerated wound recovery: cutting sites regenerate faster, producing new growth points within days rather than weeks.
- Enhanced root maintenance: continuous phosphorus supply (P=20) combined with seaweed bioactives keeps the root system active despite above-ground stress.
- Higher cutting quality: well-nourished mother plants produce cuttings with greater carbohydrate reserves, resulting in faster rooting and higher survival rates.
- Stress tolerance: organic compounds from Kelpak improve resistance to temperature fluctuations, humidity changes, and pathogen pressure.
Dosage and Mixing Order
Add 0.5 ml MAM per litre of feed water, followed by 0.2 ml Metrop Calgreen (always last). On soil, water as needed; on coco and hydro, dose daily. MAM is also suitable for foliar application on mother plants. For the complete programme, combine with Metrop AminoXtrem — the MAM + Calgreen + AminoXtrem trio is the benchmark for long-term mother plant maintenance.
250 ml: Entry Point for Clone Producers
This format suits growers running 1–5 mother plants or testing the Metrop system before committing to the 1 litre format. At 0.5 ml/L, 250 ml produces 500 litres of nutrient solution — sufficient for several weeks of daily feeding for a small mother plant room.

Can Metrop MAM be used for seedlings and young plants?
The balanced NPK 20-20-8 and seaweed extract make MAM suitable for seedlings needing additional root support. Use a reduced dosage and transition to MR1 once the plant enters standard vegetative growth. The Kelpak component is particularly beneficial for transplant recovery.
What makes Metrop MAM different from MR1 for vegetative growth?
MR1 (NPK 10-40-20) is optimised for time-limited vegetative growth followed by flowering — high phosphorus for root development. MAM (NPK 20-20-8) is designed for indefinite vegetative growth with repeated cutting stress. It contains more nitrogen for foliage regeneration and 18.7% Kelpak seaweed extract for wound recovery — functions not present in MR1.
How quickly will I see results from Metrop MAM 250 ml?
Most growers report visible improvements within two weeks of consistent use. Mother plants develop more growth points, cuttings root faster, and the overall vigour of the mother plant increases noticeably. The seaweed extract component contributes to rapid stress recovery between cutting sessions.
Should MAM be added before or after Calgreen in the reservoir?
Always add MAM first, then Calgreen last. This mixing order prevents calcium-phosphate precipitation that can occur when calcium contacts phosphorus at elevated pH. Ensure the solution pH is below 7 before adding Calgreen to maintain full bioavailability of all nutrients.
