Today, the main artificial sources of plant illumination are high pressure sodium lamps. However, in 2021, many greenhouse plants of the Russian Federation and other countries of the world are actively using LED lamps with various spectral modes mainly as additional illumination. The analysis of scientific papers has shown that there is practically no reliable data on the cultivation of the main greenhouse crops in conditions of using only LEDs without natural lighting. This does not give a complete objective picture of the efficiency of using LED lamps. The purpose of the research: to determine the effectiveness of the use of LED lamps in the cultivation of cucumber cocktail hybrids with increased planting density in a vertical farm. The research was carried out in summer-autumn and spring-summer turns in 2020–2021 on the territory of the V.I. Edelstein Vegetable Experimental Station of the K.A. Timiryazev Russian State Agricultural Academy in glass greenhouses without additional illumination and Vertical Farms LLC indoors without access to sunlight (Moscow). The object of research: cucumber hybrids F1 Larino, F1 Kvatrino, F1 Kvirk. Cucumber was grown in the greenhouse using low-volume technology, riding peat was used as a substrate. For irradiation of plants, LED modules manufactured by Vertical Farms LLC (30 W, 50×7.2 cm, in operating mode 2.8–2.9 mmol/J) were used, which were located at a distance of 0.4 m from the plants. Plants were irradiated for 16 hours a day. It was found that the cultivation of cucumber plants in vertical farms using full-spectrum LED irradiators and a planting density of 11.4 rast/m2 contributes to an increase in the total yield of cucumber in comparison with a glazed greenhouse. When growing cucumbers in a vertical farm, fewer nitrates (102–105 mg/kg) accumulated in cucumber fruits, a higher amount of sugar content (1.90–1.98%) and dry matter (6.21–6.28%) were noted compared to fruits obtained when grown in a greenhouse. It is promising to further study the cultivation of cucumber culture in vertical farms using LEDs.
