Abstract: A method for cultivating plants, wherein use is made of a multitude of cells, each comprising a container having a cylindrical or frustoconical inner side wall, which container is open at the upper side, wherein the containers are filled with a growth substrate containing a seed, and wherein a layer of powder is applied to the inner side walls of the containers before the growth substrates are placed in the containers.

Abstract: The invention relates to a method of manufacturing a culture medium on which plants can be grown. This method is characterised by a) mixing I: a particulate base material, chosen from at least one of organic and inorganic materials, with II: a thermoplastic biologically degradable binding agent, b) heating at least the binding agent in order to at least partly fluidise it, c) cooling the mixture so as to substantially solidify the binding agent and whereby at least a part of the base material becomes bonded by means of the binding agent. The method according to the invention provides an environmentally safe and plant-friendly culture medium that is biologically degradable and retains its shape well.
