<p>The invention concerns a procedure regarding the retention of water during the cultivation of seeds alternatively seedlings, cuttings or embryos, in particular when cultivating in arid regions. When needed, a nutrient substrate and/or biocides can be added to the water. The procedure according to the invention utilizes a biodegradable material as for example paper or cardboard made from natural raw materials. A characterizing part of the invention is that the growth substrate's lowest part rests on a water-repelling biodegradable material. The water- repelling material can consist of paper with contents of refined wood fibers in a homogenous mixture with wax.</p> |
