A plant propagation system is provided that includes a holder for holding at least two plants in relative spaced apart relation to enable a predetermined operation (such as, for example, a cutting operation) to be performed on each of the plants within the holder during a single pass.

A horticultural raft includes a raft body, at least one top cavity, and a group of mid cavities. The top cavity includes an upper face defining a first projected area and a lower face defining a second projected area substantially equal to or less than the first projected area. The upper face provides a seeding pattern having one or two degrees of freedom in a growing medium disposed in the top cavity. Each mid cavity has an upper face defining a third projected area that is entirely contained within the second projected area. The mid cavities are configured to contribute to buoyancy of the floating horticultural raft, allow germinants in the growing medium to communicate via capillary action with a nutrient solution when the raft is floating in the nutrient solution, and mitigate hyperhydration and asphyxiation at respective root-stem junctions of the germinants.

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.

An automated plant cultivation system is provided having multi-tiered vertically arranged horizontal magazine structures each employing seed or plant capsules with a fluid circulation and illumination and communication network controlled by an on-board processor. Particularly, the system includes a magazine structure having seed/plant capsules within seed/plant reservoirs alternately arranged between at least one of a light source substantially concealed from direct viewing. A fluid channel extends across a long axis of the magazine structure, wherein the magazine structure is adapted for use of seed/plant capsules with nutrient composite plant growth cultivation, hydroponic plant growth cultivation, aeroponic plant growth cultivation methods or combinations thereof.

A sprout lid for use with a container to sprout seeds and or beans is provided which may include a recess feature which may allow the container to be filled with water without removing the sprout lid from the container, as well as allowing proper airflow in the container. The sprout lid may also be used to rinse, strain, and drain seeds and or beans in the container.

A quilted composite sheet containing seeds makes growing microgreens and other crops simple. Each sheet is a layered composite of multiple materials including seed, grow substrate and seed cover. A user can spread a seed quilt over the surface to be planted, water, wait, and harvest.

Hydroponic apparatus has a rotary drum rotatably supported at one end from a bearing of a support stand and is accessibly open at an opposite open end by a removeable cover plate. A drive to rotates the rotary drum about the bearing. The rotary drum defines an annular watering tank therein and is configured for holding a plurality of plants within an interior thereof in use to be watered by the watering tank. An axial lamp is located within the drum to illuminate plants therein.

A Tray and Trellis System includes vertical posts or legs, longitudinal members, and cross members. Combs include tines fixed at one end to longitudinal members on one side, and releasably engaged at their other end to other longitudinal members on the other side. Further combs include tines fixed to a cross member at one end, and releasably engaged to another cross member at the other end. There may be intermediate cross members having tines fixed to them and other tines releasably engaged to them. Fixation of the tines may be by clips, rings, welding, bonding, fastening, or by molding as a single piece. The releasably engaged ends of the tines may be engaged with snap-fit slot features in the longitudinal members, the cross members, or the clips or rings, or may be engaged with open grommets inserted into openings in the longitudinal members or cross members.

A seed delivery device that includes an enclosed container inside which is encapsulated one or more plant seeds and a medium. The medium may comprise one or more particulate materials, one or more aqueous materials, or a combination of one or more particulate materials and aqueous materials. The specific gravity of the entire device is greater than the specific gravity of water. The seed delivery devices may be used to address the planting of seeds in conditions where water is or may become present.
