<p>A tray (2) includes a framework comprising first and second elongate side members (4, 6) and first and second end members (8, 10). The members (4, 6, 8, 10) support a rectangular floor of the tray, defined by a metal mesh (12a) or grid arrangement (12b). A sheet (14) of woven fabric material is arranged to define a multiplicity of elongate channels (16). The sheet (14) is supported at its ends by cords (18) which releasably engage end members (8, 10). End member (8) includes a tensioning arrangement (20) for adjusting the tension in the cords. In use, the channels (16) are filled with compost and plants are grown therein. A tray (2a) may be situated in a greenhouse with other trays (2). It may be removed from the greenhouse using a carriage device which can move underneath tray (2a), lower it and then drive it out of the greenhouse by causing it to pass under adjacent trays (2b and 2c). Other trays may be moved in a similar manner. Accessory means for cooperation with tray (2) are described and may comprise cutting apparatus (150) or a cultivator (170).</p> |
