  • Our take on the Metrop MR-1

    Metrop MR-1 is a water-soluble macronutrient base fertilizer for the vegetative growth phase. It carries heavy doses of nitrogen, phosphorus and potassium plus seaweed and plant extracts, and it is built for aeroponic and hydroponic systems while also working in soil and coco. Because it dissolves fully, it runs through drippers and lines without leaving salt buildup. It suits growers who want one simple grow-phase base rather than a shelf of bottles, though it is a base only and still needs calmag or a bloom feed later.

    Best forHydroponic and aeroponic growersCoco and soil growers wanting a clean baseVegetative-stage feeding through any irrigation systemGrowers who prefer a simple two-part program
    Pros
    • Fully water-soluble, so it resists clogging irrigation lines
    • Works in hydro, aeroponics, coco and soil
    • Macronutrient base with added seaweed and plant extracts
    • Simple to dose through any fertigation setup
    Cons
    • Covers the grow phase only; bloom needs a separate feed
    • High nitrogen makes it easy to overfeed in late veg
    • No micronutrient or calmag content of its own
    • Dosing depends on water quality and system, so it needs tuning

    About the Metrop MR-1

    Metrop MR-1 is a fertilizer for the growth phase. It is made from macro-elements that support the crop's metabolism. It is designed for aeroponic and hydroponic growing, and it also works in soil and coco.

    All ingredients are 100% water soluble, so it can be used with any irrigation system. This helps keep excess salts and nutrients from building up in the irrigation lines. It is high in nitrogen, potassium and phosphorus, and it contains seaweed and plant extracts. It can be used together with other bases and additives.

    To use it, measure the EC of your crop first. Then check the fertilizer's dose table and apply the dose that fits your needs. The brand suggests combining it with additives from the same line, such as Root+ and Rhizoxtrem.

    Questions and answers

    Is MR-1 a complete nutrient?
    No. It is a macronutrient base for the growth phase, with nitrogen, phosphorus, potassium and plant extracts. You still add calmag and a bloom feed for a full cycle.
    Can I use it in soil and coco?
    Yes. It is designed for hydro and aeroponics but works in soil and coco too. Adjust strength to the medium and watch runoff.
    Will it clog my drippers?
    The ingredients are fully water-soluble, so it dissolves cleanly and limits salt and nutrient buildup inside irrigation lines.
    When do I switch off MR-1?
    Use it through vegetative growth, then move to a bloom-phase feed as flowers set. Its high nitrogen is not meant for late flower.
    How much do I dose?
    Follow the label rate and scale it to your system and water. Start lower and raise strength as plants respond.
    Where is the Metrop MR-1 cheapest?
    At Grow Industry, for $41.11, as of our latest check.
