An innovation group consisting of expertise in strawberry cultivation, plant lighting, plant research, food science and sensoric analysis, are working on combining greenhouse cultivation of Swedish strawberries with innovative lighting technology (LED technology). The goal - year-round cultivation of strawberries with the preserved taste, aroma and color as the Swedish strawberry is known for.
Objective of the experiment: To understand on how different light intensities that sum up to equal DLI is effecting growth of lettuce. Earlier trials without far-red had showed similar results when aspect of crop production between the different ways to distribute the light over a day.
Given increasing consumer demand for fresh produce year-round, a grower’s initial investment in supplemental LED lighting is quickly offset by accelerated harvests, smarter energy consumption and a uniform, quality yield day in and day out.
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.
