The aim of this study was to compare chemical composition of lemon balm and basil herbage grown in containers under fluorescent lamps (FL) and LED modules(LEDs). There were significant differences in the response of the species for the applied source of light. The content of essential oils was greater in basil herbage under fluorescent lamps, whereas the content of essential oils in lemon balm herbage was greater under LED lamps. The basil and lemon balm plants were characterised by high content of fructose and glucose and by very low content of sucrose. There were no significant differences in the nitrates content in basil and lemon balm herbage grown under either source of light. Both the basil and lemon balm herbage were found to have higher content of macroandmicronutrients when they were grown under LEDs compared with fluorescent lamps. It can be concluded that the chemical composition of lemon balm and basil herbage was very varied and dependent on both the light and the species.
