Hydroalga is a growth promoter 100% of plant origin, manufactured at low temperature and without chemical solvents, made of Ecklonia maxima (coming from rocky seabed of South Africa seas). This product is also rich in micronutrients, vitamins, polysaccharides, natural phytohormones (auxines), as well as proteins and high-quality amino acids of plant origin from yeasts. Thanks to all its features, Hydroalga, used both in foliar applications and fertigation, is apt to achieve: bigger high-quality yields, stronger plants resistance against stress, better photosynthesis, increased resistance against fruit drop, bigger roots and less sensitivity to micro-deficiencies. We advise using Hydroalga together with fertilizers, agrochemicals and weedkillers, improving their effectiveness as well as their translocation inside the plants.
