Zenzym is a Multi-enzyme product that immediately reinvigorates worn-out media with swift breakdown of dead root matter and other untoward residue left from previous grows. This media recycling powerhouse consists of a mixture of cellulase, xylanase, pectinase and glucanase for the breakdown of dead root material and releases nutrients for the plant while promoting root growth. When your media is used for the full length of the growing cycle, it will undoubtedly be left with debris and old plant matter shed by that harvest. A major goal for most of our growers is to recycle their growing media. A product like Zenzym gives it a 2nd, 3rd, and 4th chance at life.
