The Farm of The Future Is Magenta
What color do many green plants like? The opposite of green: magenta. Nanoco
After the US, guess what country is the second largest exporter of food by dollar value? The Netherlands. One of the smallest countries in the world has become one of the biggest exporters of food.
Dutch farmers have become masters of indoor farming, as National Geographic reports. With advanced greenhouses using LED lights, hydroponics and more, they're able to grow more food, faster and in a smaller space. It's a growing trend (pun intended).
Lighting is one of the biggest costs of indoor farming, but some wavelengths (colors) of visible light are more useful than others. Magenta, for example, is a favorite of green plants. Quantum dots are can be tuned to produce magenta light efficiently.
By using wavelengths the plants want most, less overall light and power needs to be used. No power is wasted creating green wavelengths that a specific plant species doesn't need, for example.
Lights augmented by quantum dots can promote faster growth, not just on a per-plant basis, but even depending on where that plant is in its growing cycle. Certain wavelengths can be used for a young plant, and slightly different wavelengths for a more mature plant.
Researchers have also been able to grow plants faster. Nanoco, makers of the lights you see in the image at the right and above, claim that in some cases plants can grow twice as fast as with standard LED lights.
Quantum dots could be the key to indoor farms producing significantly more food, or small farms being able to produce vastly more food. Indoor farms can also exist in places not typically conducive to farming, such as the cities where most of the world now lives.
And if you look even further ahead, this would be a pretty fantastic way for us to grow a lot of food quickly in space, on the Moon or Mars, and beyond.
