The aim of the study is to compare tomato hybrids with different maturation periods in greenhouses with a hydroponic system («Phytopyramid») and ordinary soil with different lighting systems. The research was carried out in 2020–2021 at the ARRIVG – branch of FSBSI FSVC (Ramensky district of the Moscow region). The plants were grown in a polycarbonate greenhouse of «Phytopyramid» LLC. The test involved 11 tomato hybrids with different levels of precocity and different product groups of selection of the Poisk Agrofirm. An experiment with various lighting options was carried out in 2021 in the laboratory of artificial climate of the RSAU – MTAA after K.A. Timiryazev. In the experiment, 7 lighting options were used. Four hybrids of the selection of the Poisk Agrofirmwere selected: F1 Captain (ultra-early), F1 Rafinad (early-ripening), F1 Coral Reef (medium-ripe) and F1 Ogon (medium-ripe). The climate of the «Phytopyramid» plant turned out to be ideal for growing tomato hybrids of different ripeness groups. The presence of an automatic ventilation system and maximum control over all periods of plant growth and development helped to reduce the ripening time by 16–25 days compared to the traditional system of unheated protected soil. The earliest-maturing hybrid was F1 Elf (T5) in hydroponics (77.00 days) and protected soil (101.67 days). F1 Alaya karavella (T4) is the latest in maturation time (94.75 and 114.67 days. respectively). This is due to the faster passage of the plant phases of development in the conditions of «Phytopyramid» compared with placement in the soil. Binary illumination blue+red (C+K) had the greatest effect on the number of leaves compared to monochromatic green, since they are more efficiently absorbed by photosynthetic pigments. The addition of red and/or blue light LEDs can increase the mass of fresh micro-green shoots and plants.
