NGS - Rotational Strawberry Recirculating Hydroponic System in Macrotunnel

The system relies on a set of key elements and their management, with the multilayer gutter being paramount as it houses the root system and favors optimal plant development. It is made up of interconnected layers which create a multi-level circuit generating small cascades which oxygenate both the nutrient solution and plant roots.

Bag arrangement is such that the nutrient solution, after flowing through a bag section of variable length depending on the model, passes or falls down to the next level through holes/orifices on the bag side or bottom. This generates a cascade effect which oxygenates the nutrient solution and, in turn, the roots.

This recirculating system does not only provide for healthier plants. But also ensures that all irrigation water excess is collected at the end of each crop line and returned to a nutrient solution tank for analysis and reuse.
