The concept of Artificial Bio-Energetic System (ABES) of greenhouse as a synergy of power apparatus, technological processes and biological objects is considered. The comparative experiment was carried out in a light-isolated laboratory room. An index of the spectral composition of the radiation of sources KLW is proposed, which characterizes the fraction of the energy of long-wave radiation in the total flux of PAR radiation. Empirical models of the basic biometric parameters of tomato plants are obtained. The results of experimental studies are presented, which confirm the applicability of the theoretical positions in the justification of the choice of light sources for indoor plant lighting.
