Seawin's advantage:

With Seawin's unique extraction method, Seawin's polysaccharide acts as a natural chelating agent and buffering agent, making nutrients more available to plants and better PH environment for nutrient uptake. The well preserved active ingredients also trigger plants to produce its own endogenous growth and improve plants' metabolism, which then leads to better root & shoot growth, and better yield and quality. Seawin's Polysaccharide, promotes the generation of reactive oxygen species under stress, which interact with protective enzymes to improve plants tolerance to environmental stresses. In terms of soil health, the unique chelating features of Seawin's Polysaccharide promote soil aggregate structure, and Polysaccharide being a food source for soil microbes, increases soil fertility.
