Abstract: A plant-growing tray comprises a plurality of cells, each cell for containing in use a substrate for a plant or a cylindrical stabilised medium for propagating a plant. Each cell is formed from injection-moulded plastic and comprises a cell base and eight inclined side walls extending upwardly from the cell base, and each cell comprises four corner side walls having a corner wall gradient, and four stepped side walls which comprise an upper portion having an upper gradient, a lower portion having a lower gradient, and a step having a step gradient. The step is positioned between the upper portion and the lower portion, and the step gradient is less steep than the gradients of the upper portion and the lower portion of the side wall. Each cell comprises a pair of ribs on each of the four stepped walls, the ribs extending upwards from the cell base.

Abstract: A plant-growing tray for containing cylindrical stabilised media for growing plants comprises an array of flared columns, a lower end of the columns being wider than an upper end. The columns define an array of cells therebetween for containing cylindrical stabilised media, and a column comprises one or more contact edges defined by an intersection between a wall of the flared column and a virtual cylindrical surface in a cell, such that the contact edges are suitable for contacting a cylindrical stabilised medium positioned in the cell.

Abstract: A plant-growing tray comprises a tray top and a plurality of cells extending downwardly from the tray top. Each cell is for containing a substrate for a plant, for the propagation or growth of the plant. Each cell is associated with a catchment area of the tray top, and each catchment area has a sloped surface which, during watering of the plants in the tray, directs water impinging or falling on the catchment area towards the cell.

Abstract: A container for propagating or growing plants is configured to receive a substrate for propagating plants and comprises a drain hole, an inclined side wall, and a plurality of ribs positioned on the side wall and extending into the container. At least two ribs are arranged close to and parallel to one another, defining a channel therebetween through which air may flow, in use, when the container contains a substrate. In a plant tray comprising an array of cells, at least one cell comprises a rim, arranged around the drain hole on the underside of the cell, in which a thickness of the rim is greater than a thickness of the side wall. A plant tray comprising an array of cells having octagonal cell openings comprises a plurality of vents arranged between the cells and configured to allow air to flow through the tray top. A plant tray comprising vents in the tray top comprises vent rims arranged around the circumferences of the vents, the vent rims being configured to project downwards from the tray top.

Abstract: A plant-growing tray (102) comprises an array of cells (108) for containing stabilised media for propagating plants. The tray comprises a tray top (110), and each cell comprises a base (116) and an inclined side wall (114) extending from the base to the tray top. Each cell is configured to receive a stabilised medium, and comprises a plurality of projections (123), positioned around the side wall and facing into the cell, and a plurality of openings (125) defined in the side wall below the projections. The projections (123) are configured in use to support an upper portion of the stabilised medium. In a further aspect, a plant-growing tray for containing stabilised media for propagating plants is configurable in a nesting configuration with a similar tray, and comprises: a tray base configured to support a base portion of a stabilised medium; a support member, configured to support an upper portion of the stabilised medium; and an inclined tray wall connecting the support member to the tray base.
