Pure Zym is a natural soil improver that utilizes enzymes to break down dead plant material, releasing additional nutrients and promoting healthy soil life. Our new formula includes a variety of enzymes for faster and more efficient breakdown of dead plant material, allowing for improved absorption by plants. Simply shake, add 1 ml per liter of water, and use during each irrigation for optimal results. Suitable for all substrates, but not recommended for hydroponic cultivation methods due to organic origins.
