Lights can maximize plants for optimal growing. One of the surest ways for humanity to have sustainable flourishing is to be able to grow food, and even raw materials, indoors. Limitations on hydroponics, the prevailing method for indoor growing, has kept it from becoming a dominant source for food. Now, researchers at the University of Minnesota are developing a new type of hydroponics that will reduce water needs by 10% and optimize plants for maximal nutrition and minimal grow times.
Assistant Professor Nate Eylands describes the use of lights in this new hydroponics, “Quantum dots are little nanoparticles, and they absorb photons of light and change that photon into a different photon. Say you have blue light coming in, it might be red light coming out of it. So, what we’re doing is taking a liquid quantum dot and we’re spraying it on some of these plants. You can’t tell which ones of them have it. And then on the leaf surface, they are absorbing that photon, say a blue photon, and converting it to a red photon. And that might speed up the process of photosynthesis at different stages of the plant growth.”

At the University of Minnesota, researchers are experimenting with new technology to help growers use less water and produce more food — but all indoors — and it’s opening a new field of opportunity to change the way food is grown…
… assistant professor Nate Eylands… says hydroponic systems like this use a fraction of the water compared to traditional agriculture….
“Quantum dots are little nanoparticles, and they absorb photons of light and change that photon into a different photon,” Eylands says. “Say you have blue light coming in, it might be red light coming out of it. So, what we’re doing is taking a liquid quantum dot and we’re spraying it on some of these plants. You can’t tell which ones of them have it. And then on the leaf surface, they are absorbing that photon, say a blue photon, and converting it to a red photon. And that might speed up the process of photosynthesis at different stages of the plant growth.”
By altering the light spectrum, researchers hope to speed the flowering on these plants — boosting yields and making indoor production more efficient.
