The hidden key to clean, healthy hydroponic systems
ORP directly measures the disinfecting power of water
Oxidation-Reduction Potential (ORP) helps you take control of water quality, leading to healthier plants, lower risks, and a more efficient growing system.
Measuring ORP helps prevent risks such as contamination, biofouling, equipment failure, and poor crop yields while ensuring compliance with water quality certification standards.
A higher ORP value indicates a stronger oxidative environment, meaning more effective disinfection against bacteria, algae, and pathogens. It’s a key metric for ensuring clean, healthy water in hydroponic and irrigation systems.
