I visited Vietnam in September 2012 where Matthew Carr of SNV World and I set up a small duckweed production facility near Hanoi, Vietnam. This production facility consisted of 2 small wading pools filled with drinking water and one scoop of biodigester slurry. We collected Lemna duckweed from a local village pond and used it to fertilize these 2 small pools. Four days later we returned to the village and harvested the duckweed. This harvested duckweed was used to feed pigs and chickens living on site.
