Using supplemental lighting to increase light intensity in the late fall, winter, and early spring can improve yield and fruit quality, as well as optimise temperature control, CO2 and nutrients.
Everything starts with your plants and their ideal DLI. Find the right light recipe and your plants will thrive all year round. Adding LED lights to your greenhouses offers the perfect solution.
Understanding the DLI’s impact on your growing environment
DLI (or Daily Light Integral) considers the number of photosynthetically active photons that are delivered to a specific area over a 24-hour period. It is a particularly useful variable to describe the light environment of plants.
DLI affects many plant traits from leaf anatomy, chemical composition and physiology to plant growth and reproduction. More information can be found in these studies by Cornell University and on the NASA Technical Reports Server.
As one can expect, the DLI is reduced from late fall to early spring, with the shortest day of the year on December 21st. This leads to plants getting less than the amount they require for their optimal growth in the winter months.
Introducing supplemental lighting helps increase the DLI inside greenhouses and recreate a perfect growing space for your crops. Our engineers calculate the necessary DLI for your plants and growing environment to provide a solution that minimises costs.
