A kind of concealed environmentally friendly hydroponic culture system of fluorescent tube,Have identical quantity and mutual hydroponic culture pipe side by side including at least up and down two layers and every layer,The hydroponic culture pipe upper limb offers plural number cultivation mouth,The another hydroponic culture pipe upper layer and lower layer are respectively with 5 degree with leaning angle and drain slope inclination reversed each other； One sets the water level adjustment lid of the what lower port of hydroponic culture pipe height； One sets the capping of the what hydroponic culture pipe height higher ports； One is connected to the connecting tube of water level adjustment lid and the capping； One be connected with the top layer hydroponic culture pipe height higher-end send water tank； One water storage box being connected with the lowest level hydroponic culture pipe height lower end,Tool one send water motor in the water storage box； And one set plant illumination light source above the what hydroponic culture pipe. If so, not only exempt from consumptive material, it is capable of washing and it is environmentally friendly do not waste it is outer； Also moisture content and nutrient can be provided in the demand of different length according to plant root； It more can reach saving system installation space and increase the purpose of plant culture area.一種燈管隱藏式環保水耕栽培系統，包括至少有上下二層且每層具相同數量而相互併排的水耕栽培管，該水耕栽培管上緣開設有複數栽培口，另該水耕栽培管上層與下層分別以5度以內傾角且互為反向的流水坡度傾斜；一設於該水耕栽培管高度較低端口的水位調整蓋；一設於該水耕栽培管高度較高端口的封蓋；一連通該水位調整蓋與該封蓋的連接管；一與最上層該水耕栽培管高度較高端相連通的送水箱；一與最下層該水耕栽培管高度較低端相連通的蓄水箱，該蓄水箱內具一送水馬達；及一設於該水耕栽培管上方的植物照明用光源。如是，不但免耗材、可清洗且環保不浪費外；還可依植物根部在不同長度的需求提供水份與養份；更可達到節省系統設置空間與增加植物栽培面積之目的。
