Hydroponic units and systems

Abstract

A configurable hydroponic unit and system are disclosed. The configurable hydroponic unit (100) comprises a water tank (110). The water tank includes at least one partition bar (1114, 1115) and at least one movable dam element (150). The at least one separation bar is provided at the bottom edge of the tank for separating the water tank into a plurality of groove areas. The at least one movable dam element is movably mounted within the tank to prevent nutrient flow. Said at least one divider bar and said at least one movable dam element forming a configurable channel in which the nutrient solution flows within the tank. Due to its modular characteristics, the configurable water culture unit can be stacked in turn to form a multi-layer hydroponic system which enables the vertical circulation of the nutrient solution.

Description

technical field [0001] The invention relates to the field of hydroponic technology, in particular to a hydroponic technology for cultivating plants using artificial light in a planting factory, and more particularly to a hydroponic unit and system. Background technique [0002] As a soilless cultivation method using mineral nutrient solution to cultivate plants, hydroponics technology using artificial light indoors, such as LED lights, has been increasingly used in planting factories. [0003] In a conventional hydroponic technique, in hydroponic equipment, a culture pond or a culture tank is typically used. [0004] To ensure an even distribution of nutrient solution, the traditional shallow water cultivation model often seen in greenhouses usually requires a single-layer cultivation tank with a length of more than 30 meters and a sloped arrangement with a slope of about 15 degrees. However, plant cultivation equipment that uses artificial light to cultivate plants indoors...

AI Technical Summary

Problems solved by technology

[0008] Therefore, the whole process of installing a conventional plant cultivation equipment as described above is rather complicated

The disassembly and / or maintenance of the above-mentioned plant cultivation equipment is also very complicated and requires high labor costs

Also, the metal frame, screws, and other metal parts are prone to rust over time, and the PE film has a short lifespan and needs to be replaced every two years or so

Furthermore, the multi-layer plant cultivation equipment itself exceeds the load-bearing requirements of the floor of ordinary buildings, and it is difficult to build a multi-layer cultivation system in a multi-storey building

[0009] These problems of the above-mentioned traditional plant culture technology limit its wide application in practical operation
