    Signify and RIAT pioneer growing tomatoes and cucumbers in a vertical farm without daylight

    Eindhoven, the Netherlands – Signify (Euronext: LIGHT), the world leader in lighting, and RIAT, an innovative farming enterprise located in Russia, have together pioneered the growing of tomatoes and cucumbers in a vertical farm without daylight. During the research phase in 2019, RIAT achieved a yield comparable to advanced traditional greenhouses using Philips GreenPower LED grow lights.

    We already had facilities of sufficient height at our disposal, therefore there was no need to invest in building a glass construction. But as the building had no windows, we needed a high-quality lighting system to fulfil the intensive lighting requirements of tomatoes and cucumbers. In 2019, Signify provided its Philips GreenPower LED grow lighting, helping us to achieve a yield performance comparable to traditional greenhouse operations."

    RIAT’s indoor farm is located in the center of the Ivanovo region, enabling the company to distribute its tomatoes, cucumbers and 19 types of green crops to its own RIAT stores within an hour after harvesting. RIAT has a special technique to fold the long stems, allowing it to grow the 3.5m high plants indoors.

    “With a harvest of 2.7 to 3.2 kg of cucumbers per m2 every week, and 1.7 kg per m2 of tomatoes, we started making a profit as of the second year of operation,” Bukharev added. “In addition to that, the quality of the product is very high, there’s hardly any waste and we sell 99% of what is being grown.”
     

    “To mimic nature as much as possible, RIAT has chosen a combination of different kinds of Philips GreenPower LED toplighting and interlighting, bringing light both from the top and right in the canopy where the light is needed the most for photosynthesis. While using different kinds of lights, the light recipe can be adjusted based on the crop that is grown,” said Sergey Khokhrin, business Development Manager CEE/Russia & CIS at Signify.

     

    Signify, in collaboration with several research partners, discovered that the red spectrum in light stimulates growth of plant cells and tissues, while the blue spectrum influences the processes of cytodifferentiation (racemes initiation, bines and root formation, flowering). The combination of red and blue with the addition of white and other colors in Philips LED grow lights creates lighting conditions that are as close to natural daylight as possible. Additionally, RIAT is using bumblebees for pollination, as in traditional greenhouses. The bees don’t experience difficulties due to the absence of natural light.

     

    When choosing a lighting supplier, RIAT tested LED modules from different manufacturers from around the globe. “By using Philips LED lighting modules, we managed to achieve maximum stability and a light output of 18 g/mol. This is why we chose Signify. The area equipped with LED lamps is currently 3,800 m2. Soon, we are going to launch a new area of 700 m2 to grow lettuce which will also be equipped with Philips LED lighting,” Bukharev added.
