An octagon greenhouse like this one takes in light through eight clear walls and a pyramid roof, and the 45 degree pitch sheds rain and most snow on its own.\u003c\/p\u003e\n\u003cp\u003e### How many vents does this octagon greenhouse have?\u003c\/p\u003e\n\u003cp\u003eThis octagon greenhouse has four top-hinged vents with automatic openers, set high in four of the walls.
