Designer Daan Roosegaarde has installed red, blue, and ultraviolet lights on farmland in the Netherlands as an art installation and a “light recipe” that helps plants grow without as much pesticide. “Light is not decoration, it’s activation and it’s communication,” says Roosegaarde.

Specific combinations of colored lights improve plant growth significantly and, crucially, reduce the need for pesticides by up to 50 percent. Designed to blend in with the landscape and avoid creating any sort of pollution (light, sound, or otherwise), the exhibition uses red, blue, and ultraviolet lights positioned relatively low to the ground.

The high-density, solar-powered LED lights to shine across 20,000 square meters of farmland and emit a combination of four different light recipes. The installation is entitled GROW, and the devices situated around the field move up and down to distribute light evenly. The recipes come from photobiology light science research and studies have found that different combinations of wavelengths strengthen plant metabolisms which in turn increase resistance to a variety of diseases and pests.

This is a good technology to study to help our agricultural country an edge for the farmers to produce more agricultural goods.
