Effect of Roof Shape On Plant Growth to be Studied With New Research Greenhouses


Pennsylvania Flower Growers #223


Analytical and model studies show the amount of sunlight available to plants in greenhouses is influenced by several variables: time of day, season of year, cloud cover and geographic location. While it is not possible to control these factors, it is possible to control such variables as building orientation, structural shape and covering of a greenhouse which affect the quantity of sunlight reaching plants within the greenhouse. A study of the latter three factors has indicated that a curved surface transmits more total sunlight than a flat surface and that rigid plastics such as fiberglass panels are acceptable as covering materials. The fiber glass panels can be formed to a curved surface and have mechanical properties that result in minimum opaque framing for a safe structure.
