Legend Ancestral Tau






Improve dramatically and Stimulate the Growth

of Both Roots and Shoots in Aquatic Plants

Intensify Mineral Absorption and improve

Disease Resistance


Legend Ancestral Tau™ is an all-natural, biological growth enhancer for aquatic plants. Its advanced formula contains phytohormones, minerals, and nutrients that dramatically stimulate the growth of both roots and shoots in aquatic plants. Phytohormones are a group of naturally occurring compounds that play crucial roles in regulating plant growth in a wide range of developmental processes, including cell division, formation and activity of shoot meristems, induction of photosynthesis gene expression, leaf senescence, nutrient mobilization, seed germination, root growth and stress response. Used regularly, it also enhances mineral absorption and improves disease resistance. It is non-toxic and completely safe for all plant varieties as well as for fish and aquatic organisms.

Legend Ancestral Tau™ is a comprehensive carbohydrate, vitamin, amino acid, and polyunsaturated fatty acid supplement that addresses the micro and trace nutritional requirements of plants.

Legend Ancestral Tau™ contains ascorbic acid in a base of chlorella that contains a rich assortment of amino acids and vitamins.

During the first 10 to 14 days after application, Legend Ancestral Tau™ works to stimulate root growth beneath the surface. After this initial induction period, significantly enhanced growth in the leaves and stems of the plants will occur.
