Thanks. I just learned something about crops. Personally, I like light pipe tecnology. But I still don't get it. If wheat is already maxised for land/light and cannot be improved then what could be the theoretical advantage to indoor growing of wheat partially under light pipes? Area/energy-wise the best it can ever grow indoors is surely no better than on the roof.
