The present invention relates to a hydroponic device for afforesting a wall surface. The hydroponic device comprises: an inner pot for accommodating a hydroponic plant an outer pot having a set width and length, and accommodating one or more inner pots therein variable vertical frames formed in a rectangular direction corresponding to the width and length of the outer pot with respect to an indoor wall surface, and of which length is varied according to a height of the wall surface multiple horizontal frames formed between the two variable vertical frames, and supporting the outer pot, so a plurality of outer pots may be disposed in multiple layers in an up and down direction and a water circulating and supplying unit for sequentially circulating water according to each of the outer pots. Each of the outer pots is equipped with a connection module coupled with the other outer pot neighboring in a width direction and capable of performing water circulation therewith, thereby being able to be formed corresponding to a height and a width of the wall surface. Accordingly, modulation is performed by using a variable vertical frame and an outer pot connection module, and a hydroponic plant is optimally disposed corresponding to a size and a shape of an installation wall surface, so outward appearance may be improved. Also, an indoor wall surface is used, so an installation space is minimized and maintenance can be very easily performed. Moreover, a modulated hydroponic technique is applied, so a plant can be easily stored and maintained, compared to conventional technique. Consequently, the hydroponic device can be semi-permanently used, so efficiency in maintenance can be maximized.COPYRIGHT KIPO 2016본 발명은, 벽면녹화용 수경재배장치에 관한 것으로, 수경재배 식물이 수용되는 내분과 설정된 너비 및 폭을 가지고 마련되며, 하나 이상의 내분이 내부에 수용되는 외분과 실내의 벽면에 대하여 상기 외분의 너비 및 폭에 대응하여 장방형으로 설치되되, 상기 벽면의 높이에 따라 길이가 가변되는 가변수직프레임과 상기 2개의 가변수직프레임 사이에 마련되며, 복수의 상기 외분이 벽면의 상하 방향으로 다단으로 배치가 가능하도록 상기 외분을 지지하는 다수의 수평프레임과 상기 각 외분을 따라 순차적으로 물을
