A container for growing plants includes a bottom wall, a first side wall extending perpendicular to the bottom wall, and a second side wall extending perpendicular to the bottom wall and parallel to the first side wall such that the bottom wall, the first side wall, and the second side wall at least partially define a plant growing chamber. Furthermore, the container includes a lid configured to selectively occlude access to the plant growing chamber. Additionally, one of the bottom wall, the first or second side walls, or the lid includes a rail and another of the bottom wall, the first or second side walls, or the lid defines a groove such that the rail of the container is configured to be received within a groove of a first adjacent container and the groove of the container is configured to receive a rail of a second adjacent container.
