Abstract
Cultivation cell for seedlings and a tray formed from such cells, comprising apertures breaking the cell upper rims. Thereby growth disturbancies in roots growing close to the substrate surface are prevented. The tray comprises air channels, and growth of surface roots across the upper apertures from one cell to another is prevented by structural elements giving the tray rigidity.
