PRISMA Vertical farming, namely the practice of producing greens in buildings, is an area where artificial light plays a crucial role. How does light actually influence the growth of plants, such as lettuce or herbs?
HAMBY LED lighting in these vertical farms can influence the taste, appearance and nutrition values of many leafy greens and vegetables, increase yields and shorten growth times. By tuning the light spectrum, for example, we can increase the nutrient uptake of lettuce, or control whether basil will taste mild or strong. Every plant has different lighting requirements. Together with Michigan State University, we are searching for the optimal light recipes to ensure that basil, lettuce and other leafy greens get their own, entirely personalized lighting treatment.
PRISMA And why do we speak of "vertical" farming – what exactly is vertical about it?
HAMBY It simply means that the plants grow above and below each other in special grow boxes on multiple levels, which is to say, vertically. This setup ensures that more plants can grow in small spaces. This is particularly important in places where space is tight, such as in big cities.
PRISMA What is OSRAMs function in the joint research project with Michigan State University (MSU)?
HAMBY The Innovation department supplied the MSU research team with a connected-lighting system which we developed here at OSRAM. They use that system in their controlled-environment lab to create practically any lighting conditions.
