Plant growth and reproduction are driven by photosynthetically active radiation (PAR), defined as wavelengths between 400 and 700 nanometers. This interval is often separated into three distinct “color” bands for plant research. Modifying the intensity of red, blue, green wavelengths, along with additional near-UV (380-400 nm) and far-red (700-780 nm) bands, can influence a variety of plant characteristics, such as growth rate, chemical composition, and more.
The precision linear image sensor of the LI-180 records intensity and composition of these five wavebands at the single-nanometer level with a single click. Optimize the composition of your supplemental lighting and track your spectrometer data over time for long-term validation of your lights and lighting strategy. Monitor degradation of your custom lighting system, plan for seasonal changes or upgrades, and design species-specific light recipes using the LI-180 Spectrometer.
Measure real-time changes from spectral manipulation, height adjustment, and plant positioning. In one click, the LI-180 records dozens of variables including PAR (as color-specific photosynthetic photon flux density (PPFD)), photon flux density (PFD), irradiance (W/m2), and more. Select a measurement to see details, such as ratios of red to blue or red to far-red intensity.
