Abstract
There is disclosed a structure for supporting the growth of plants, comprising a flexible tubular element in the wall of which slits are provided. Closure means define with the tubular element an elongated enclosed area that is filled with a fluid and root permeable material for supporting the roots of plants. A fluid nutrient is supplied by a pump to the material. The tubular element may be suspended from one of its ends and supplied at the upper end with the fluid nutrient to support plant growth through the perforations from the particulate material. The construction is cheaply and easily manufactured, and easily used by a lay person.
