<p>Soiless plant cultivation techniques have hitherto employed substrates such as foam panels through which the plant roots grow, mainly to develop on the underside of the panel. To promote root development in the substrate material itself, a method of soillessly cultivating a plant comprises growing the plant on a substrate which is provided with air passages. A substrate suitable for the cultivation of plants has air passages occupying from 5 to 40% of its volume, which air passages have cross sections of from 0.07 to 3.2 cm<2>.</p> |
