The role of light in the plants world

Abstract

This letter describes the differences in how people and plants perceive light. This is important in some artificial light applications. In particular, it concerns the horticulture area in which LED lighting is increasingly used. There is a misunderstanding about the specifics of the environment in this area. As a result, even experienced lighting professionals design greenhouse lamps in the same way as for people. This article describes the negative consequences of this approach.
