A series of detailed studies were performed to evaluate the growth of selected Angiosperms on substrates composed of the effluent from waste disposal processes and to measure growth and photosynthesis under a variety of atmospheres and lighting conditions. The plants used most extensively were Brassica chinensis Chinese cabbage, Amaranthus gangeticus Tampala, and Chicorium endiva endive. Some preliminary experimentation was also performed using Beta vulgaris cicla Swiss chard and two other members of the genus Brassica, kale and collards. The results indicate that growth on effluents of biological waste disposal processes will be satisfactory only upon supplementation, further treatment, or adaptation to the effluet. Growth under narrow-band fluorescent lamps, or combinations of several colored lights, in no case approached that observed under light sources that were specifically designed to promote plant growth. The results indicate that major advances must be made in the employment of artificial light if economical use is to be made of plants in closed regenerating systems. Author
