PURPOSE: To provide the subject equipment for water culture, capable of uniformly supplying a nutritive solution to many cultured plants, free from overflow of the nutritive solution even when the roots are spread, having a circulation system for supplying the nutritive solution and capable of application to displays for indoor use or outdoor use.

CONSTITUTION: On the outer side of a flexible inner pipe 1 for supplying a nutritive solution for water culture, a corrugated intermediate pipe 3 having, in the longitudinal direction, two or more through holes 2 through which the above-mentioned nutritive solution flows in and out is arranged and, on the outer side of the corrugated intermediate pipe 3, a flexible outer pipe 6 through which the nutritive solution flowing out from the corrugated intermediate pipe 3 can flow, having an opening part 5 capable of accommodating an artificial culture medium 4 is arranged. The inner pipe 1, the corrugated intermediated pipe 3 and the outer pipe 6 are inclined at a desired gradient so that the above- mentioned nutritive solution may flow and the nutritive solution is circulated.
