Perforated ducts extend into the grain bin from the ventilation openings. According to one embodiment upright support legs support the hopper wall above the foundation. Each upright support leg has a hollow interior chamber to direct air from an inlet manifold structure to the ventilation openings in the hopper wall. According to another embodiment, an outer support wall supports the hopper wall above a floor structure which collectively enclose a manifold space which directs air from a blower into the ventilation openings in the hopper wall.
