modeled facilities were closed systems, the irrigation and misting would result in no runoff from the greenhouses. In both systems, microcuttings would be misted 60 times per day at 98 mL·m −2 for 4 weeks which required a 3.73 kW submersible pump

The use of reclaimed water as an irrigation source for nursery crops is of increasing importance because many nurseries are located near urban areas that have experienced rapid population growth. Population growth results in increased demand for
