Engineer the invisible foundation of your plants. Metrop Rhizo Boost is a highly concentrated mineral root stimulator, formulated to trigger explosive root development right from cutting and transplanting. Rich in immediately available macro and micro-elements, it builds a network of white, dense and branched roots able to absorb more water and nutrients. The result: faster growth, sturdier plants and a clearly higher yield potential. Its professional Metrop quality makes it a benchmark for indoor growers who leave nothing to chance.
Designed for growers who chase performance, Rhizo Boost works exactly where it matters most: the root zone. By strengthening cell walls and keeping the substrate clean, it helps plants move through the delicate cutting and transplant stages without stress. The first effects show within a few days: whiter, more numerous roots and a clear surge of new growth. And because every grow is different, the BloomLED team is on hand to advise you on fitting Rhizo Boost into your feeding programme.

Rhizo Boost stimulates the multiplication of rootlets and the formation of a dense root mass. The larger the root system, the more water and nutrients the plant absorbs, and the more vigorous its canopy growth becomes.
True to Metrop’s professional reputation, Rhizo Boost concentrates immediately available macro and micro-elements. A minimal dose is enough to deliver a maximum effect on the root system.
Beyond nutrition, Rhizo Boost has antiseptic properties that keep the rhizosphere clean. Protected roots are healthy roots, far less exposed to substrate pathogens.
With just 30 ml per 100 L of water, a single 1-litre bottle makes up to ~3,300 litres of solution. An unbeatable cost-per-use for professional-grade performance.
Metrop is trusted by expert growers for the purity and concentration of its formulas. Rhizo Boost fits perfectly into a demanding mineral nutrient line.
Dilute 30 ml of Rhizo Boost in 100 litres of water, i.e. about 0.3 ml per litre. Apply the solution when watering, mainly at the start of the cycle, on young plants, cuttings and after transplanting. Stick to the dose: the formula is highly concentrated, so there is no need to overdose.
At which growth stage should I apply it?Rhizo Boost performs best early in the plant’s life: rooting of cuttings, transplanting and the first growth phase. It is during these stages that establishing a powerful root system sets the tone for the entire cycle.
Is it suitable for soil, coco and hydroponics?Yes. Its soluble mineral formula works equally well in soil, coco or hydroponics. In every medium it promotes a dense root network and better uptake of nutrients.
Is it compatible with my other nutrients?Rhizo Boost fits into a complete feeding programme, alongside your growth and bloom nutrients. For optimal synergy it naturally pairs with the Metrop mineral range. Introduce it gradually and watch how your plants respond.
A single litre of Rhizo Boost makes up to ~3,300 litres of nutrient solution: a concentrate of mineral efficiency with an unbeatable cost-per-use, for roots that make all the difference.
