Designing an optical system for plant research in space

Light is as an environmental factor affecting plant growth. So far, various light sources have been used to grow plants in closed systems and space studies. Traditional light sources have some problems and are not suitable for space research. The biggest problem of them is the need for the high energy source, power supply weight, and heat production. LED light spectra were designed to solve plant cultivation problems in space for the first time and are recently used in terrestrial research such as greenhouses and plant cultivation rooms. The LED spectra have different colors, but laboratory studies are needed to determine the plants' involvement for these spectra. In this study, LED light technology, effect of spectra on the growth, production of metabolites and optical receptors are investigated.
