A hydroponic cultivation system includes a plurality of seedbeds, a hanging part, and a transport mechanism. A plurality of seedlings of a plant to be cultivated is transplanted to side surfaces of the plurality of seedbeds. The hanging part hangs each of the plurality of seedbeds while the plurality of seedbeds is arranged in a predetermined horizontal direction from a planting side of the seedlings to a harvesting side of the seedlings. The transport mechanism transports the plurality of seedbeds in the predetermined horizontal direction while widening spaces between the seedbeds in the predetermined horizontal direction in a stepwise or continuous manner.

Hydroponic cultivation system comprising seedbeds and a transport mechanism

A hydroponic system () is provided with a light-collecting apparatus () having a pair of reflecting plates () that are vertically arranged in parallel with a culture surface () of a culture panel () of a hydroponic unit (). During a process in which natural light taken from a light-collecting opening () propagates while repeatedly reflected by opposing reflecting surfaces of a reflecting plates (), by allowing seedlings p that are transplanted into the culture panel () to be irradiated with the light through a light-emitting hole () bored in the reflecting plate (), a culture object can be grown efficiently at a low cost by taking natural light from the outside.
