Tray for plants

1. An assembly for holding plant material, comprising:

a holder; and

at least one insert which can be respectively placed in the holder for achieving an assembled state and can be removed therefrom for achieving a disassembled state, wherein the insert comprises at least one cell defining a plant position, said cell comprising at least one wall, at least one side wall, and a bottom to be filled during use with at least one content selected from the group consisting of plant material and a growth substrate,

wherein:

the holder and the insert are not identical to each other; and,

the at least one side wall comprises a remainder segment that contacts the bottom, and an opening extending to a top of the cell sized and positioned to enable access to the plant position, in the disassembled state, through each opening, wherein the remainder segment is adjacent to the opening, said remainder segment is between the opening and the bottom and is configured to maintain the at least one content in the plant position in a disassembled state of the assembly.

2. The assembly of claim 1 , wherein the insert comprises at least one row of at least two cells.

3. The assembly of claim 2 , wherein the cells together define a longitudinal direction and the opening in the at least one side wall of each cell is oriented transversely of the longitudinal direction.

4. The assembly of claim 2 , wherein the insert comprises a maximum of two mutually connected rows of cells.

5. The assembly of claim 1 , wherein the holder comprises at least one ridge.

6. The assembly of claim 1 , having at least two separate inserts, wherein at least one of the inserts comprises a ridge.

7. The assembly of claim 1 , wherein the holder further comprises aligning means configured to act on the at least one insert to provide a desired alignment of the insert.

8. The assembly of claim 1 , wherein the holder further comprises positioning means configured to act on the at least one insert to provide a desired positioning of the insert.

9. The assembly of claim 1 , wherein the substantially enclosing wall of the insert diverges in a direction away from the bottom.

10. The assembly of claim 1 , further comprising one or more walls including ridges and protrusions for aligning the insert during assembling of the assembly.

11. The assembly of claim 1 , further comprising ridges and protrusions configured for positioning the insert during assembling of the assembly.

12. A kit comprising an apparatus; and an assembly:

said assembly comprising:

a holder; and

at least one insert which can be respectively placed in the holder for achieving an assembled state and can be removed therefrom for achieving a disassembled state, wherein the insert comprises at least one cell defining a plant position,

wherein said at least one cell comprises at least one wall, at least one side wall, and a bottom to be filled with at least one content selected from the group consisting of plant material and a growth substrate,

wherein the bottom comprises a cell bottom opening, and

wherein the at least one side wall comprises a remainder segment that contacts the bottom, and an opening to enable, in the disassembled state, access therethrough to the plant position for controlled extraction of the content in the cell wherein the remainder segment is adjacent to the opening,

said apparatus comprising:

at least one pusher, wherein the at least one pusher is configured to contact contents of the cell through the opening in the at least one side wall; and

a pin, wherein the pin is configured to contact the contents of the cell through the cell bottom opening and the pin is configured to be able to be inserted into the contents of the cell to maintain the contents of the cell in an upright position during removal of the contents of the cell.

13. The kit of claim 12 , further comprising a gripper, said gripper capable of receiving from the at least one pusher and the pin the contents of the cell after removal thereof from out of the cell by the pusher and the pin.

14. A method of assembling the assembly according to claim 1 , comprising:

providing the holder;

placing the at least one insert in the holder so as to provide the at least one cell defining a plant position;

filling the at least one cell with the at least one content selected from the group consisting of plant material and a growth substrate;

removing the insert from the holder so as to achieve a disassembled state;

maintaining the at least one content in the plant position in the cell wherein said remainder segment is configured to maintain the at least one content in the plant position in the disassembled state;

accessing the plant position through the at least one side wall opening; and

controllably extracting the at least one content from the cell.

15. The method of claim 14 , wherein the placing comprises aligning at least one of the holder and the at least one insert for a desired alignment of the insert.

16. The method of claim 14 , wherein the placing comprises positioning the holder and the at least one insert for a desired positioning of the insert.
