I visited a large aquatic farm just the other day. It was really interesting to see how these plants are being grown in bulk for export. Basically the farm has many concrete ponds with murky water and they are all roofed with nets to prevent excessive sunlight. No CO2 whatsoever.
And guess what! Hairgrass and Glosso are grown without water, but in large damp plots. There were just turfs and turfs of it. $2 got me a fistful of hairgrass, but all clumped up.
