Abstract
A plant growth body for germinating seeds for promoting the development of a root system for a cutting is constructed from a plurality of corrugated layers. Each corrugated layer has a plurality of parallel ridges and valleys that form channels extending between the adjacent ridges. When the corrugated layers are stacked one on the other, the plant growth body is formed so that the channels extend through the body. The material of the corrugated layers is penetrable by the roots so that the roots can penetrate successive ones of the corrugated layers and channels respectively. Further, the material of the corrugated layers preferably promotes capillary liquid flow through the plant growth body so that the roots are supplied with water.
