A circulation type planting wall comprises a plurality of tube bodies which are arranged as a wall, the tube bodies are capable of growing plants. The tube body has two ends respectively provided with a water-entry member and a water-exit member. In each two vertically-adjacent tube bodies, the positions of water-entry and water-exit members arranged at two ends of one tube body are opposite to those of the other tube body, and a water-falling port of the water-exit member of upper-located tube body is spacedly aligned to a water-receiving port of the water-entry member of the lower-located tube body at the same side, so that water is allowed to pass through each tube body from top to bottom via the water-entry and water-exit members located at two ends thereof. Besides, water falling from the water-falling port of the water-exit member of the lowermost-located tube body is pumped to the water-receiving port of the water-entry member of the uppermost-located tube body, thus to cyclically supply water to plants growing in every planting holes.一種循環式種植牆,係複數管體排列成牆狀,管體可栽種植物,管體的兩端分別具有入水件和出水件,任二上下相鄰之管體係一者兩端所設之入水件和出水件的位置和另一者相反,且在上之出水件以其落水口隔空對準同邊在下之入水件的接水口,令水由各管體兩端之入水件和出水件由上往下通過各管體,且在最下方之管體的落水口落出的水以抽水泵經管路抽回位在最上方之管體的接水口,以循環供給各種植孔所栽種之植物水分。1‧‧‧管體14‧‧‧種植容器2‧‧‧入水件3‧‧‧出水件4‧‧‧抽水泵41‧‧‧管路5‧‧‧基座51‧‧‧儲水管511‧‧‧開口512‧‧‧開口52‧‧‧插設部
