[Wikipedia] Cultivation: Large scale cultivation is done in outdoor water tanks, mostly in connection with wastewater treatment. Tanks are fed with wastewater and the floating duckweed is harvested from the surface. It is then further used as a biofuel from industrial wastewater or as animal feed from agricultural wastewater treatment facilities. (link added by Mary Ann Machi)
