Supporting tools for Precision irrigation

The Grodan group shares its years of built up expertise and experience with growers through its tools and advice focused on Precision Growing. Efficient and effective water management is a precondition for a successful crop.

The group currently offers water management tools which support the grower in precision irrigation. These tools help the grower to apply water and nutrients to the root zone with precision, limiting the consumption of energy, water and fertilissers.


Based on professional growers’ needs for higher accuracy and reliability in monitoring water content (WC), electrical conductivity (EC) and temperature in substrates, the Grodan Group has introduced a state-of-the-art innovation: the GroSens® wireless, multi-sensor measuring system. This wireless and flexible multi-sensor measuring system enables highly accurate and reliable 24/7 real-time insight into the WC, EC and temperature of the root environment. The GroSens system, in combination with Grodan stone wool substrate products and advice, is the best way of achieving optimum results in production and cost savings.

The patented GroSens system will replace the current Grodan WCM’s. For more information, please visit the GroSens page.
