Novelty: three-level hydroponic cultivation system composed of a pipeline and containers fixed therein. Constitution: three pipelines-sections in the interior of which there are located in-series positioned perforated containers. Function mode: the three in-series connected pipelines-sections are successively filled up with a solution susceptible to impregnate said sections, to be drained therefrom, to be collected in an external tank and return, finally, with the assistance of a pump, to the initial tank from which said solution will newly recirculate in the system, after completion of its potential loss. Advantages: a plant can receive the exact quantity of solution and oxygen required; the solution’s volume is inferior to that of other related systems; solution losses are exclusivelyrelated to absorption by plants; lower energy consumption is required for the solution’s flow; compared to energy expenses, the production ratio of the system is particularly high. |
