"Lemna minor (common duckweed) and a Wolffia sp. were grown in submerged growth systems. Submerged growth increased the productivity unit volume (P/UV) of the organisms and may allow these plants to be used in a controlled ecological life support system (CELSS)"

Gale J, Smernoff DT, Macler BA, MacElroy RD. (1989) "Carbon balance and productivity of Lemna gibba, a candidate plant for CELSS." Adv Space Res 9(8):43-52. [ abstract ]
"The photosynthesis and productivity of Lemna gibba were studied with a view to its use in Controlled Ecological Life Support Systems (CELSS). ...yields of 18 g DW m-2 d-1 were obtained. ...We conclude that a CELSS system could be designed around stacked, alternate layers of transparent Lemna trays and lamps. This would allow for 7 tiers per meter height. Based on present data from single layers, the yield of such a system is calculated to be 135 g DW m-3 d-1 of a 100% edible, protein-rich food."
