In greenhouse operations, water is essential not only for plant irrigation but also for climate control and system cleaning. Precision irrigation methods such as drip systems and flood benches often use fertigation, where water is blended with nutrients and delivered directly to plant roots. Water is also used in fogging systems to regulate humidity and temperature, and many greenhouses collect rainwater for irrigation. Because water sources vary and are often recycled, treatment is essential to protect plant health and maintain reliable system performance.

Walchem and Iwaki provide a complete solution for managing greenhouse water quality. Walchem Intuition-6 and Intuition-9 controllers monitor and regulate pH, conductivity, and ORP, while EZ and EWN series metering pumps deliver precise doses of acid, base, nutrients, or disinfectants. Iwaki MD series centrifugal pumps efficiently transfer bulk fertilizer components into mixing tanks. Together, these systems enable automated recipe control, consistent fertigation, and effective rainwater treatment. Remote access through Walchem Fluent further enhances oversight and efficiency, helping growers maintain ideal growing conditions with minimal manual intervention.

Walchem and our distributors can provide plug-and-play systems that incorporate the Walchem controls, sensors and metering pumps for your application. Contact us or your local distributor to learn more.
