摘要
Plants are grown in a greenhouse in vertical columns two metres tall with their roots (11) embedded in a water-absorbent substrate (4) and foliage (6) protruding. The walls (2,3) of the column are of coarse mesh sheathed in UV-resistant plastic sheet. The outer wall (2) has perforations (5) into which plant roots (11) are inserted. A plastic water bag (8) is sealed to the inner column (3) just below the perforations (9) through which water (10) flows into the substrate (4). Surplus water drains from perforations (7) in the base of the outer column.
