An Army researcher, ironically, is working on a project that one day could foster the ability to grow edible produce on Navy submarines. Dan Holman, a technician at the Army Natick Soldier Research, Development and Engineering Center in Massachusetts, has spent the past year testing the possibility and practicality of growing fruits and vegetables in shipboard hydroponic gardens. “We tested 83 different varieties of plans, including vegetables and fruits – everything from strawberries to zucchini, beans and rhubarb,” Holman said. “About 51 of those 83 we tried grew well in hydroponic conditions.” While the project is still in its infancy, Holman – a former sailor – believes hydroponic farming could provide each of the armed services with a new method of providing healthy food at minimal cost and space.
