<p>The invention relates to a plant growing arrangement comprising several successive rows of troughs for plants, wherein transport means are provided for transporting said troughs along a cultivation field and successively increasing their spacing as the plants grow. Said transport means comprise successive graspers rows (1, 2, 3) formed of graspers (1a...1c, 2a...2c, 3a...3c) co-acting trough by trough (14). The graspers and/or grasper rows can be brought into engagement with arbitrary groups of troughs for transporting several chosen troughs at a time along the frame. The spacing between successive graspers rows (1, 2, 3) is adjustable by a driving mechanism in connection with the transport. The invention is especially well suited for the automatic cultivation of lettuce grown in separate pots in said elongated troughs (14).</p> |
