A seedling transplanting system is provided that utilizes a seedling feeder that is configured to fit between a tray of seedlings contained within a series of chain pots and a hydroponic trough. The feeder includes a ramp and a chute that direct the seedlings from the tray into the trough. A pair of guide surfaces, which form ramp sidewalls, help the seedlings to self-right as they are drawn into the hydroponic trough. A restraining jig aids in establishing and maintaining the relative positions of the seedling tray, feeder and trough during the transplanting process. A pulling tool simplifies the transplanting process by providing means for pulling a pair of media strips along with the captured chain pots into the hydroponic trough.
