It feels like there should be a more direct way to grow stuff. AppHarvest is doing something interesting. Why plant in dirt outside and rely on lossy transmission of fertilizer and water to the plant? Plus fungus, parasites, etc. A controlled environment where you can get the nutrients and water directly to the plant seems a lot more efficient. I know the capex is huge but still. We probably should all be eating less (and wasting less) food here in the US.
