Description:
The report gives results of an evaluation of potentially beneficial uses of industrial waste heat for production of bedding and foliage plants, using conventionally and warm-water heated greenhouses in Fort Valley, GA. Each greenhouse was a plastic covered, 30 x 72-ft quonset. The research greenhouse was heated and cooled with simulated warm condenser cooling water; the control greenhouse was conventionally heated and cooled during the 9-month test. During 1979, cultivars of 10 leading ornamental plants, 8 species of foliage plants, and tomatoes used as bedding plants were studied for growth rate, survivability, and susceptibility to disease in the humid greenhouses. No statistically significant difference in growth rate for 7 of 10 ornamental and 4 of 8 foliage plants was observed in the two greenhouses.
