The natural power of seaweed extract
GK-Organics® Seaweed Liquid comes from Ascophyllum nodosum brown algae. Seaweed extract is naturally very rich in minerals and trace elements, micronutrients, amino acids and vitamins which are essential for plant growth. More importantly, seaweed powder contains numerous growth hormones such as cytokine and gibbellin which stimulate cell division, plant growth and root network development.
