Patent attributes
A molded body for improving cultivation conditions for plants, which is suitable inter alia for arrangement in a plant holder. The molded body has a tapered projection and is arranged in such a way that the projection protrudes into the plant substrate in the plant holder. The projection has elements allowing an exchange of substances between the interior and the surroundings of the projection. This allows the targeted introduction of air, water, nutrients and auxiliary substances into the plant substrate and the root conglomerates. The molded body has a recess which acts as a water reservoir that is separate from the plant substrate. The molded body is water-permeable in the upper part and essentially impermeable to water at the bottom, in the tip of the projection.
