Hygrozyme is developed using a proprietary bio-fermentation process, made from ALL NATURAL ingredients that produce a supply of BACTERIA-FREE enzymes and complex chains of amino acids. Why would you introduce unknown bacteria to a sterile environment? Hygrozyme has a specific gravity of nearly zero and has virtually no effect on ppm. Specific Enzymes in a growing medium can eat dead protein removing potential areas where illness can develop. Enzymes are natural and therefore enviro friendly catalysts that speed up chemical reactions. Through this breakdown, plants are better able to obtain nutrients that are released by enzymatic process allowing for more nutrients, less attacks, and bigger, stronger, faster, plants. Hygrozyme is the result of over 10 years of research, testing and approvals to get it to market. There is no longer a need to introduce or create crop vulnerability with a foreign germ culture to your sterile growing environment and there are NO concerns of a limited shelf life or spoilage.
