The Bell Peppers that are planted in the Earth Boxes are between 10 and 11 inches tall. All of the bell peppers were started on the same day and then transplanted on the same day. Last year I grew some in a Earth Box and some in the Raised Bed garden and I didn't see a whole lot of difference. This year I planted half in an Earth Box and half directly in the ground (new garden area - heavy clay soil) and the difference is pretty remarkable.
