PURPOSE: A bed for water culturing is provided to maximize production efficiency per unit area of a bed by maintaining an interval of culturing holes formed in the bed.CONSTITUTION: A bed for water culturing comprises: a bed part(10) shaped in a board, comprised in a rectangular shape, connected one another in a longitudinal direction of a water tub, and settled in the water tub multiple culture holes inserted with a holder part holding growing plants or seeds of plants and passed through the front and back part of the bed part in a spot shape, and forming regular triangles by the most adjacent three culture holes to maintain a same interval one another in a state of being arranged and connected together a first row arranged for the multiple culture holes to have a same interval in a longitudinal direction of the bed part of the bed for water culturing a second row arranged in a parallel direction with the first row for the multiple culture holes to have a same interval along the longitudinal direction of the bed part the most adjacent three culture holes in the first and the second row form a triangle a third row arranged for the multiple culture holes to have a same interval in the longitudinal direction of the bed part, and adjacent to the second row by corresponding to the first row and a fourth row arranged for the multiple culture holes to have a same interval, and adjacent to the third row by corresponding to the second row. The most adjacent three culture holes in the second and the third row forms a triangle, and the most adjacent three culture holes in the third and the fourth row forms a triangle. The bed part floats on water in the water tub by being made of a Styrofoam material or an empty plastic material.COPYRIGHT KIPO 2013본 발명은 식물이 일면에 식재되며 하이드로 볼 재질또는 현무암 재질로 형성되는 벽체가 적층되어 벽을 이루고, 이러한 벽체가 주변의 공기와 유해물질을 정화시키는 공기 청정용 벽체에 관한 것으로서, 바닥에 고정되는 지지부에 고정되며, 일면에 공기정화용 식물이 식재되는 본체부와, 상기 본체부에 설치되어 식물이 식재되는 배양토의 수분과 온도를 감지하는 센서부와, 상기 본체부에 수분을 공급하는 물 공급 펌프와, 상기 본체
