FEATURE SPECTROSCOPY


The green shoots of horticulture light analysis


Plants are being stimulated to grow or ripen with targeted LED light, which can be monitored by fast and small spectrometers, as Matthew Dale discovers

hanks to their long lifetimes, high energy-efficiencies and excellent colour rendering index, light emitting diodes (LEDs)


are replacing incandescent lamps in an increasing number of applications. One sector where LEDs are not only acting as replacements for conventional light sources but helping to advance a whole industry is in horticulture, where LEDs are being used to increase plant growth by up to 40 per cent through the


delivery of unique compositions of light. Here, spectroscopy systems are vital for


not only ensuring that the correct mix of light, or ‘light recipe’, is being delivered, but for allowing horticulturists and farmers to monitor their lighting systems, even though they are not the typical spectroscopy user.
