The organisation of even minor additional lighting on the General light background gives a noticeable effect and is the primary task of vegetable growing. The influence of different peaks of 440-450 nm and 650-660 nm of the spectrum for optimal plant growth was experimentally studied. The lack of functional mathematical models for describing the development of plants indicates the need for scientific justification of the optimal spectral composition of the photosynthetically active zone on the example of a specific culture of protected soil. The dynamics of plant height growth in various lighting options is compared: without additional artificial lighting, when using a DNAT lamp, a GLP-FH-56-B lamp, a GLP-FH-56-R lamp, a GLP-FH-56-RB lamp. The obtained functional models of growth in the first two months of vegetation with a different spectrum of additional lighting with good correlation describe power equations.
