A body of plant growth material 1 (eg particulate perlite and sphagnum moss) is contained within an envelope 3 (eg of nylon mesh) and is supported by a tubular member 2. Liquid nutrient may be fed from a reservoir 4 via capillary tubes 5 and may be drained off through an apertured lower end portion of tube 6 into a container 12. The liquid nutrient may alternatively be recycled by a pump. The plants are inserted through slits made in the envelope. <IMAGE> |
