A greenhouse, a real greenhouse – with sun and soil – this makes all the sense in the world. But hi-tech lettuce? Dumb. Yet a Subway in Tokyo is growing five percent of its lettuce hydroponically, in the shop. This is local? This is junk. No soil, no sun means hi-energy input (lights) and hi-nutrient input (fertilizer). A complete waste, and tasteless no doubt to boot – flavor comes from sun and soil, not from water and lightbulbs. Sheesh.
