In order to increase plant yield and reduce radiation sources energy consumption, we introduce the concept of the cycloadaptive photomode (CAPM), which adapts to the plant development substages (steps), dynamically changes lighting parameters to optimize their growth and development, and promotes increased photosynthetic pigments synthesis. Based on the results of assessing the spectral composition of LED devices effect on the Lactuca sativa L. development, it was determined that the light-­emitting device based on the automated change in the spectral composition of radiation and the photosynthetic photon flux depending density on the stage of plant development in accordance with the cycloadaptive lighting mode leads to increase Lactuca sativa L. yield by 2 times, as well as a decrease in the amount of water used to form 1 g of dry matter by 2.5 times compared to natural lighting.
