has worked alongside leading growers to develop advanced solutions and systems for every type of crop.
The HANNA fertigation system delivers precise control of pH and fertiliser injection. Unlike the flow-based systems of the past, it constantly measures the water EC and pH, allowing the system to add the exact fertiliser concentration to the irrigation mix. The HANNA system is a bypass system that does not restrict flow or pressure. This lets the user introduce fertiliser accurately at between 1 and 70 m3 /h.
