An extendable plant tray assembly comprising a plurality of plant holders in a grid structure, wherein in a first direction said plant holders are movably connected through an extension system arranged to move said assembly between a retracted position and an extended position, the assembly including at least one grid structure element holding a plurality of plant holders in a second direction transverse to said first direction, wherein the plurality of plant holders are arranged on the at least one grid structure element in a staggered manner, alternating a plant holder with a plant holder receiving space, wherein the extension system comprises extendable connection members which are configured to connect at least two grid structure elements, and wherein the extendable connection members are detachably connected to said at least two grid structure elements.

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.

The invention concerns a tray (20) for cultivating a crop or a precursor thereof, particularly a strawberry plant cultivation tray, wherein the tray (20) comprises an upper wall (32) with a number of holders (42) for holding therein the crop or precursor thereof, wherein the holders (42) are formed by a number of longitudinally extending rows of cup-shaped recesses in the upper wall (32), herein the upper wall (32) also comprises a groove-like recess (33) arranged between adjacent rows of cup-shaped recesses (40) and extending in longitudinal direction (PI).

The present invention provides a composition comprising at least one organic component having particles between 1 and 4 mm, and a cured thermoset polymer, and wherein a w/w ratio of the organic component to the thermoset polymer within the composition is between 4:1 and 10:1. Furthermore, provided herein are articles in a form of planting pots comprising the composition of the invention. The invention also provides a method for manufacturing of planting pots.

A modular planting system comprising a plurality of container units to receive therein a growing medium and one or more plants or plant material, the container unit being configured such that adjacent abutting container units define at least one or more voids therebetween; a frame with a plurality of engagement projections which extend at least partially into the at least one or more voids defined between adjacent abutting container units to maintain said container units in the abutting arrangement and positioned above apertures defined in the support frame member; and a water impermeable base that supports the frame spaced apart by a predetermined distance from an upper surface of the water impermeable base.

A horticulture tray support system including a plurality of horticulture trays. Each one of the plurality of horticulture trays defines a plurality of growing cells. A stand includes a plurality of vertical supports spaced apart along a length of the stand. A horizontal support extends along the length of the stand between at least two of the plurality of vertical supports. The stand is configured to support the plurality of horticulture trays above a surface that the plurality of vertical supports are seated on.

A hydroponic growing system is presented. The system can include multiple growing trays in a vertical arrangement, where a pump supplies the top-most tray and each lower tray is supplied by the overlying tray, and where the plumbing elements for supply and drainage are arranged to one side of the system. The system includes variations to support different crop types within the same system, including removable growing structures for root vegetable, microgreens and supports for vining crops. The system can monitor and adjust the nutrients and other features of the systems water profile to concurrently group multiple crops in differing developing stages.

Panel for floating cultivation of plants on water, includes parallel grooves at a top side extending longitudinally, adapted for receiving a substrate and a number of plants or precursors in the substrate, each groove extending through the panel from a first top plane to a second parallel plane. The panel includes air chambers at a lower side extending substantially below the second plane, each of the air chambers allowing therein formation of air roots of plants supported in the substrate of the grooves. At the second plane, each groove is spaced apart from the circumferential side wall of the air chamber it debouches in when projected onto a plane normal to the longitudinal direction, each of the grooves including at least two side support surfaces extending parallel to the groove and below the top side, the side support surfaces adapted for substantially completely supporting the substrate in the groove.

A weed barrier includes a rigid body defining a plurality of basins. The basins have bottoms with holes therethrough for planting garden plants. In a particular embodiment the bottom surface of the weed barrier includes a plurality of hose channels configured be positioned over a hose. Several example configurations of rigid weed barriers are disclosed. Some example weed barriers include flanges that facilitate the adjustable arrange of the weed barriers with respect to one another.

A flexible seedling tray with at least one carrier tab for lifting the seedling tray. The seedling tray has a plurality of upwardly tapered cells arranged in rows and columns. The cells can be connected or joined together across an upper terminus to which is attached the at least one carrier tab. When the seedling tray is lifted by the at least one carrier tab, the flexibility of the seedling tray and the taper of the cells causes the cells to come together, bringing the base surfaces together to form a stable arc across the bottom side. The force of the cells pressing against each other provides support and rigidity to the seedling tray for easier transport. When placed on a surface, the cells separate and are supported on the surface.
