“…The Liebig's law logic suggests that this adding will do no harm, if it really is an adding of red LEDs, and not redistribution of energy from other ranges in favor of red light. An interesting and important work was carried out in 2013-2016 at the Institute of Biomedical Problems [7,8,9]: researchers investigated how adding narrow-band red LEDs of 660 nm to white LEDs of 4,000 K / Ra = 70 affect the growth of Chinese cabbage.…”

The highest intensity of photosynthesis is obtained under red light, but plants die or their growth gets disrupted if only red light is used. For example, Korean researchers [1] have shown that under pure red light the amount of the grown lettuce is greater than under a combination of red and blue light, but the leaves have a significantly smaller amount of chlorophyll, polyphenols and antioxidants. And the researchers at the Faculty of Biology of the Moscow State University [2] have found that the synthesis of sugars is reduced, growth is inhibited and no blossoming occurs in the leaves of Chinese cabbage under narrow-band red and blue light (as compared to a sodium lamp).What kind of lighting is needed to get a fully developed, large, fragrant and tasty plant with moderate energy consumption?

“…В России эти технические системы наиболее известны под термином фитотроны. В последние годы появились и модификации фитотронов для решения вопросов выращивания растений для космического питания и медицины [2], а также класс фитотронов -синерготроны с программно-управляемыми параметрами, включая и режимы освещения светодиодными источниками света [3].…”

In order to study the effect of low-energy monochrome radiation on the germination of rapeseed of the new variety Antares, the authors used light-emitting diodes of blue (440 nm), green (525 nm), red (660 nm) and far red (730 nm) light, as well as those of UV-A radiation (380 nm) with an intensity of 0.367–6.904 µmol/m2* s on different spectra. Different types of monochrome radiation affected the germination of seeds and the growth of sprouts in different ways. According to the indicators of germination energy, seed germination, weight of 100 sprouts, and yield of green mass, the best results were obtained when germinating using the green light. Based on experimental data, the patent was issued for the invention “The activation method of rapeseed germination under monospectral illumination”. Irradiation of seeds with the monochrome far-red light significantly reduced the germination ability and yield of sprouts.

Full and healthy human nutrition is characterized by the presence of green vegetable crops in the diet, which are rich in vitamins and useful components for humans. The need for them is observed year-round and all-season. Therefore, green vegetable products must be grown not only using traditional industrial technologies, but also in small businesses and private households. The realization of technology is ubiquitous, year-round cultivation of leafy vegetable crops in an artificial environment is possible using small-sized forms of cultivation facilities – irradiation chambers and boxes, grow boxes, phytotrons, etc. In this case, the main technological operation is the necessary light mode for plants: with the spectrum necessary for plants development and growth, with the necessary intensity and mode of irradiation. The developed irradiation units (camera and box) allow growing green vegetables at any time of the year, in any territory allotted for this, in the quantity necessary for consumption, etc. These units allow automatically monitoring the parameters of the air environment and soil, and, if necessary, adjusting it to create a comfortable environment for plant development. Experimental studies and processing of the results allowed concluding that by varying the spectrum and intensity of light-emitting diodes in the developed structures of irradiation units depending on the growth phase of green vegetable crops, it is possible to obtain products of higher consumer and commercial quality, with the necessary biochemical composition and characteristics.
