Recently, urban farms for growing green and berry crops with artificial light are gaining popularity. The effect of different parts of the spectrum in the visible region on vegetable and berry crops has been studied extensively, but the influence of ultraviolet and far red radiation requires more detailed studies. The purpose of the work was to study the influence of the spectral composition of the radiation of LEDs on the flowering and fruiting of strawberries. For research Elan F1 and Florian F1 hybrids of everbearing strawberries were chosen. Plants were grown in phytocameras on racks with artificial LED lighting. It has been established that with a fraction of the far red component of at least 15 % in radiation, an increase in leaf area and the length of peduncles occurs.
