In order to make smaller greenhouses self-supporting, and maximize profits in larger operations, it is necessary to maximize growing space within the greenhouse. Greenhouse benchmarking as long been based on revenues and profits per square foot of greenhouse. Adding more height to conventional greenhouse structures is very expensive due to the large amounts of steel and structure involved. One of the benefits of Sprung Structures is that it is comparatively inexpensive to add height. ARK’s vertical racks can then turn this height into more growing space, affordably providing 75% more growing space per square foot of greenhouse for various non-traditional greenhouse crops.
