A metering system for an agricultural system includes an inductor. The inductor includes a receiving portion configured to receive plantlet casings at a feed rate, a conduit coupled to the receiving portion and configured to receive the plantlet casings from the receiving portion, where the conduit is configured to convey the plantlet casings to at least one row unit, an air source fluidly coupled to the conduit and configured to provide an air flow through the conduit to convey the plantlet casings to the at least one row unit, and a physical feature configured to block flow of the plantlet casings toward the air source.
