Sunless Farming Touted as Answer to World Food Problems
The idea of a small warehouse sporting ultra-efficient water use, zero pesticides, and energy-efficient LED bulbs (possibly powered by solar or wind), placed right next to markets and feeding a city is appealing, but exactly how practical? The question is will these plants that rely on human inputs be nearly as nutritious as plants grown with natural inputs? The researchers state that plants need only certain wavelengths to grow, which is why LEDs would work just as well, or better, than sunlight. But do we honestly know enough about the synergy of plants and ecosystems -- and our bodies -- to be able to raise crops that nourish us?
