It is a great idea - it reduces one of the hardest things in produce sales - the farm to table transportation. A few points: Author shows a picture of a 25-day old bibb lettuce plant under this text (not caption): "The seedlings stay in darkness for around five days, allowing them to propogate. Once that happens, the LEDs are switched on, and within three days, micro herbs are ready for harvest." Micro herbs are useful for garnish or a fancy-pants restaurant $15 appetizer. There isnt much solving the worlds food problem with some magical plants that grow 3" tall in 5 days (the bottom picture is microgreens in a container). Nothing in the article says how much room they have in London for this. How many bomb shelters are there in London? It is good for leafy greens. Don't think you're growing tomatoes and peppers and avacados down there - the energy required for temp and lighting for fruiting plants is much higher (lets say 4x the wattage compared to leafy greens/lettuce).
