Soluble Seaweed
back  Back

Our Soluble Seaweed powder contains extracts from three different types of seaweed – sargassum, ascophyllum nodosum and laminaria.  Sargassum is rich in alginic acid and in cytokinins.  Alginic acid gives improved water retention whereas cytokins are growth hormones.  Laminaria contains a good proportion of a compound called laminaria polysaccharide.  This ingredient is an anti-viral compound.  Ascophyllum nodosum has a high content of minerals.  It contains over 80 different trace elements and can be added to growing media or used as a foliar treatment or seed soak
