Clean Substrate = Healthy Plants

Hesi PowerZyme is a plant booster designed to optimise the quality of your plants' substrate. Even the best developed root system is affected by the quality of the substrate. The roots need a high oxygen content and an environment that is rich in microorganisms and free from rot. The main ingredient of PowerZyme is a biotechnologically derived extract of enzymes obtained from a Trichoderma fungus. These enzymes ensure that small dead plant parts consisting of cellulose are immediately broken down into their essential parts. The components of the cellulose are sugar molecules that are used as food by both the plant and the microorganisms.

  • Use continuously throughout the plant cycle to keep your medium clean.

Did you know? 

A root grows continuously and forms new root hairs every few days. The old hairs are pushed out, which leads to the substrate becoming contaminated, especially in smaller pots. These impurities reduce the oxygen supply and attract both fungus and bacteria. With cellulose breaking enzymes, everything stays clean.
