Hydroponic lettuce and greenhouse tomatoes

One of the largest hydroponic lettuce farms in Poland: 2.5 hectares of lettuce grown all year round under plant lighting, and 2.5 hectares of greenhouse tomatoes. The owner bought the generator after two months of trials, which cleared the water of Pythium, Phytophthora and algae and also disinfected the gutters and multiplexes. Producing its own HClO makes the farm's lettuce and tomatoes more ecological and more economical.
