A hydroponic system includes a container, a broth, and a plurality of cultivating boards. The container has a first side and second side disposed oppositely. The broth is filled in the container. The cultivating boards are disposed in the container, and include a plurality of hydroponic vegetables cultivated thereon. Each of the cultivating boards corresponds to one of a plurality of cultivating steps of a cultivating period of the hydroponic vegetables. The cultivating boards are sequentially arranged from the first side to the second side, and also sequentially arranged along the cultivating steps of the hydroponic vegetables.一種水耕植物栽培系統,包含槽體、培養液,以及複數個栽培板。槽體具有相對的第一端及第二端。培養液填充於槽體內。栽培板置於槽體中,栽培板上分別種植有複數個水耕植物。其中每一個栽培板上之水耕植物對應至水耕植物之栽培週期之複數個栽培階段之一。栽培板沿著第一端至第二端依序排列,且沿著水耕植物之栽培階段依序排列。10‧‧‧栽培系統100‧‧‧槽體102‧‧‧第一端104‧‧‧第二端110、110A、110B、110C‧‧‧栽培板120‧‧‧培養液130、130A、130B、130C‧‧‧水耕植物150‧‧‧輸水管160‧‧‧排水管A-A‧‧‧線
