Found this video with some time lapse tests. Pretty neat. But notice that they laid them over to the side with very wide rows...much easier for them to stand up with nothing on top. Even sideways with those extra wide rows, the VT stage corn came up somewhat after a week, but pollination and then formation would be really iffy with many cobs laying on the ground.
