An existing XPI customer had an idea to maximize the amount of grow space in their facility. After laying out the initial concept, XPI engineers designed a system that met the client’s goals. The resulting system used a welded steel support framework, large extruded PVC towers with removable and interchangeable grow cups, and a rotomolded base/water reservoir. Sourced items such as pumps, sprayers and adjustable wavelength LED’s further enhanced the system.
