Abstract

Describes the energy consumption and biological effects of fluorescent, incandescent, and high pressure sodium lighting on the growth of poplars, white spruce, and jack pine in a greenhouse. At similar light levels the biological effects of all three light sources were similar. The incandescent lamps consumed several times more energy than the other two light sources.

Keywords
