Indoor Farming?

The Dutch are working on it:

You’ve heard of paint by numbers? Get ready for feed-the-world by numbers. Dutch agricultural company PlantLab wants to change almost everything you know about growing plants. Instead of outdoors, they want farms to be in skyscrapers, warehouses, or underground using hydroponics or other forms of controlled environments. Instead of sunlight they use red and blue LEDs. Water? They need just 10% of the traditional requirements. At every stage of their high tech process, PlantLab monitors thousands of details (163,830 reports per second!) with advanced sensors to create the perfect environment for each individual type of crop. In short, they create a high tech ‘plant paradise’.

That would ding land values.
