A wall material for a cell-structure plant growing container and a cell-structure growing container made of the material

摘要

The invention relates to a wall material for a cell-structure plant growing container com­prising several layers out of which at least one is of a decayable material, such as paper, and which is characterized in that it com­prises at least three material layers bonded together, all the layers being permeable to water and nutrients and the middle layer being formed by a nonwoven or reticulate material impregnated with a growth control agent or comprising firmly attached to its both sides a growth control agent, or a layer of decayable material, such as paper, in which the side facing said middle layer is coated with a growth control agent. The invention is also concerned with the use of said wall material, and to a cell-structure plant growing con­tainer made of the material.
