Hygrozyme is a true breakthrough in enzyme based products that breaks down old root mass to allow for and stimulate new growth. It is a root rot and disease inhibitor that also helps controls the growth of algae. This enzymatic formula is designed to break down proteins in the soil and allow for faster uptake of nutrients by the plant. Manufactured in an entirely unique way, Hygrozyme offers growers a number of advantages over competing products. It is bacteria free meaning that it has a virtually unlimited shelf life and there is absolutely no risk of introducing living bacteria into your system. Works great for both hydroponics and soil gardening. Hygrozyme is OMRI listed (organic) and highly recommended.
