Various light wavelengths and intensities allow selective intervention in the metabolic processes of agricultural crops and ornamental crops. Yield, coloration and taste, as well as other features, can be influenced in this way. The latest research shows that not only is this process impacted by photosynthetically active radiation (PAR) – in the range of 400 to 700 nanometers (nm) – but that shorter and longer wavelengths also influence plant development.
With Phytofy RL, six spectral channels – from a natural far-red end-of-day light to UV light – can be addressed individually and the photosynthetic photo flux density (PPFD) planned and controlled precisely in real time: 385 nm, 450 nm, 521 nm, 660 nm, 730 nm as well as a warm white channel with 2,700 Kelvin. At the same time, a large number of LEDs in the fixture allows a higher photosynthetic photon flux (PPF).
Phytofy RL is already being used by NASA and Michigan State University. Osram is using it to carry out research of growth, anthocyanins and taste, conducted in a climate chamber at the TU Munich.
