Abstract
A seed receptacle includes a housing defining a seed chamber within, a seed inlet formed in the housing, a seed outlet formed in the housing, and an air inlet separate from the seed inlet and mounted to the housing. The air inlet includes a first end attached to the housing and defining a first aperture, a second end, opposite the first end and defining a second aperture, and a channel defining an airflow path between the first end and the second end. The air inlet has an elasticity and a weight such that the second end sags relative to the first end.
