"Nobody Really Cares": The Rural Voter Problem

48. I suggest that you look up tower farms, wavelength tuned grow lights and

turnover cycles. Grow towers can be made as tall as the world's tallest building because they don't need sunlight. There are companies already making greens in grow towers, the seedling to harvest time is something like one week. The one limit to grow tower efficiency is cheap energy, as the cost per BTU drops, grow towers become more efficient, without energy factored in, they are now 4x more efficient than a field. The correct technical term is vertical farms. A number of large companies have build skyscrapers for Rev 1 and Rev 2 efficiency evaluations.

I admit that I don't know about cabbage, you pulled up a specific vegetable, but realize that grow towers can use soil as well as nutrient baths. I would assume that cabbage can be grown since Bob lettuce is now grown, the limitation may be on the cost side since Bob lettuce brings more money than cabbage does.
