In this second post in our series on daily light integral (DLI), we demonstrate how greenhouse growers can identify a target DLI to determine how much supplemental lighting is needed during winter months with less natural sunlight. Adjustable-spectra LED lighting systems make it possible to provide crops with near constant summertime DLI 365 days/year. This strategy can be used to ensure vigorous plants through every stage of growth and deliver quality yields consistently year-round.
With the shortest days of the year upon those of us in the Northern Hemisphere, which means a scarce six hours of daylight at Heliospectra’s plant research lab in Gothenburg, Sweden, we’re focused on how to make the sun shine…even when the sun is not. Optimizing light in your greenhouse or CEA facility generally equates to happy plants and reliably large yields.
Today we are happy to publish results that the Heliospectra Plant & Light Research Lab, together with SP Food and Bioscience, found in a recent study focused on inducing the color red in lettuce with the help of specific LED lighting strategies.
