benefits provided by brassica microgreens. The ability to impact the phytochemical content of brassica microgreens has been recently investigated using SS LEDs. In terms of light intensity, Samuoliené et al. (2013) grew four species of brassica

Schefflera arboricola is a member of the family Araliaceae and one of the most popular foliage plants used to landscape interiors. Generally, low light intensities, typical for indoors, increase leaf drop and reduce leaf quality ( Conover and
