The influence of 222nm UV-C radiation on plants
Description
The increasing introduction of safe Care222 light to occupied spaces raises questions about the effects of this light (and other UV-C wavelengths) on materials and other living species, like plants. It is important to have an understanding of this topic to avoid disappointment and unintended effects in the application. This article gives a brief insight into the current, basic understanding of the plant damaging effects and reasons of UVC and provides some guidance how to minimize the effects
