Abstract: A horticultural container dispensing system has a gravity-fed pot supply source having a plurality of linearly spaced pot paths and supports a plurality of pot stacks along the pot paths in a nested configuration. A pot provisioning apparatus has retention members to selectively release an end-most one of the plurality of pots from each pot stack at a release location. A pot engagement apparatus has a plurality of pot gripper devices associated with the pot paths to selectively engage an internal surface of the end-most one of the pots in the respective pot stack at the release location. A carriage apparatus selectively translates the pot gripper devices between the release location and a dispense location. The pot gripper devices selectively disengage the internal surface of the end-most one of the pots, respectively, at the dispense location. Pot grippers and provisioning apparatuses are interchangeable to accommodate differing pot sizes and shapes.
