Devices, systems, and methods for depositing plant seeds are provided herein. Some embodiments include a seeder head device that includes a body having a proximal end and a distal end spaced a distance from the proximal end, a bore extending through an interior of the body from the proximal end to the distal end, a first hold arm disposed within the bore and coupled to a first actuator, and a second hold arm disposed within the bore and coupled to a second actuator. The bore includes a proximal opening at the proximal end and a distal opening at the distal end, and is shaped and sized to receive seeds at the proximal opening. The first hold arm and the second hold arm are movable to selectively allow one or more of the seeds to fall under force of gravity (or other force) to the distal opening of the bore.
