Grow by Daan Roosegaarde How can cutting-edge light design help plants grow more sustainably? How can we make the farmer the hero? Daan Roosegaarde’s artwork GROW is an homage to the beauty of agriculture and is inspired by scientific light recipes which improve plants’ growth and resilience. GROW consists of a design-based light recipe that shines vertically across 20,000m2 of farmland with leek (Allium porrum). You experience the artwork as ‘dancing lights’ across a huge agricultural field. The light is poetic, and inspired by photobiology light science technologies which have shown that certain recipes of blue, red, and ultraviolet light can enhance plant growth and reduce the use of pesticides by up to 50 percent.
