Which is more important? PAR (μmol) or spectral quality? We examine the characteristics of sunlight (solar radiation) and explore how plants have evolved to exploit this energy for photosynthesis. Finally, we look at how different grow light technologies have been developed to help indoor gardeners create the best quality artificial light for their indoor plants.
