Pure Zym - Breaks Down Dead Plant Materials

Pure Zym is loaded with natural enzymes. These enzymes are catalysts that work by accelerating chemical reactions, in this case breaking down dead organic matter. This process effectively clears out the substrate, making plants less vulnerable to pathogens, limiting the potential for root diseases like pythium. At the same time, the broken down matter can be reabsorbed by plants as fertiliser, giving them an extra boost and improving overall growth and vigour.

Enzymes are particularly useful to growers who re-use soils because there's a greater level of leftover organic matter to be broken down. With that said, enzymes will make a big impact even if you're using totally fresh substrate.
