MACRO Serum is a highly concentrated liquid/paste extract derived from Macrocystis pyrifera kelp, functioning as an organic plant nutrient. This product has been developed to deliver superior results due to its concentrated formula, which ensures greater efficacy in its application. MACRO serum includes growth promoters, chelated macro- and micronutrients, amino acids, and oligosaccharides. Furthermore, it contains natural phytohormones inherent in the kelp, which optimally stimulate plant growth. With Seaweed Serum, you will receive an exceptional quality product that provides superior outcomes for crop development and performance.

Thanks to its high solubility and low molecular weight, Seaweed Serum is ideal for customized formulations, enhancing existing blends and facilitating their commercialization. Its ability to complement and enrich mixtures makes it an exceptional choice for optimizing crop performance.
Additionally, due to its manufacturing process focused on the extraction of sulfated polysaccharides, we are able to concentrate a higher quantity to provide greater impact on the results, while the heavier minerals in the kelp that are not proportionally extracted remain within balanced concentration ranges based on its composition.

This product acts as an enhancer for all elements present in the formulation of finished products.
It contains alginates, low molecular weight oligosaccharides bound by β-1,4-mannuronic acid (M) and α-1,4-guluronic acid (G), present in Macrocystis pyrifera. Furthermore, it includes fucoidan, laminarin, and mannitol in the form of oligosaccharides, which are reserve sugars in the macroalga.
Its main functions in crops include promoting germination, enhancing disease resistance, improving nutrient absorption by plants, stimulating root growth, and activating biological functions that support plant development.
