2. Product Description
The highest commercially available dry seaweed extract concentration from pure Ascophyllum nodosum. Advanced solvent-free extraction and gentle drying preserve maximum levels of natural cytokinins, auxins, gibberellins, betaines, mannitol, alginic acid, laminarin, and fucoidan. Designed for professional formulators, large-scale growers, and export markets requiring shelf-stable, ultra-potent seaweed biostimulant in flake form with outstanding solubility and bioactivity.
