The container of claim 4, wherein the inner profile comprises the first and second formations consecutively arranged about the side wall of the container. 6. The container of claim 4, wherein the first formation is configured to interfit with the first abutment of the nester to prevent rotation of the nester relative to the receiver. 7. The container of claim 6, wherein the second formation is configured to interfit with the second abutment of the nester to prevent rotation of the nester relative to the receiver. 8. The container of claim 1, wherein at least one of the first and second formations comprises spaced intrusions about a circumference of the side wall. 9. The container of claim 1, wherein the first and second abutments includes at least one of a groove, a rib, a threading, and a step that is engaged by one of the first and second formations when nested in an operative position. 10. The container of claim 1, wherein each of the first and second abutments comprises a downwardly facing surface when the container is viewed in an upright orientation and a lip formation extends downwardly from an outer portion of the first and second abutments. 11. The container of claim 10, wherein each of the first and second formations includes a protrusion for locating on the downwardly facing surface such that the protrusion is located behind the lip formation. 12. The container of claim 1, wherein the first abutment is located intermediate to the base of the container and the opening of the container, and the second abutment is located intermediate to the first abutment and the base of the container. 13. The container of claim 12, wherein the outer profile comprises the first and second abutments consecutively arranged about the side wall of the container. 14. The container of claim 13, wherein the first abutment is configured to interfit with the first formation of the receiver to prevent rotation of the nester relative to the receiver. 15. The container of claim 14, wherein the second abutment is configured to interfit with the second formation of the receiver to prevent rotation of the nester relative to the receiver. 16. The container of claim 1, wherein the container comprises adjustable openings that may be opened and closed to allow the container to change between watertight for use as the receiver or non-watertight for use as the nester. 17. The container of claim 1, wherein the container comprises a plurality of openings to permit drainage. 18. A set of containers that comprises at least one receiver and one nester according to claim 1. 19. The container of claim 1, wherein the container forms the receiver in which fluid can be contained, wherein the other container forms the nester in which growth medium for a plant can be located and roots for the plant can extend into fluid contained in the receiver when the nester is positioned within the receiver, thereby allowing the growth medium contained in the nester to be immersed in the fluid of the receiver, wherein the level of immersion decreases from the lower operative position to the intermediate operative position to the upper operative position, and wherein each of the lower, intermediate, and upper operative positions are stable positions. 20. A method of stacking a container with another container, having an alike sidewall, the method comprising: stacking the container with the other container in a nesting relationship such that the container forms a receiver and the other container forms a nester that is positioned in a first operative position within the receiver, by engaging one of first and second abutments of an outer profile of a side wall located at different heights from the base of the nester with one of first and second formations of an inner profile of a side wall located at different heights from the base of the receiver, the inner profile of the sidewall of the receiver interfitting with the outer profile of the sidewall of the nester, the side wall of each container extending from the base of each container and defining an opening;rotating the nester about a longitudinal axis of the receiver; andadjusting the relative positions of the containers by engaging one of the at least two abutments of the outer profile of the nester on one of the at least two formations of the receiver and thereby supporting the nester in at least three operative positions within the receiver, including a lowered operative position, an intermediate operative position in which the first abutment of the nester engages the second formation of the receiver, and an upper operative position in which the second abutment of the nester engages the second formation of the receiver, wherein the intermediate operative position is raised from the lower operative position and the upper operative position is raised from the intermediate operative position. 21.
