Cultivation & Processing
Farmers tie seedlings onto long-line ropes anchored just below the surface, where moving currents keep oxygen levels high. After six to seven weeks at sea, mature thalli are cut, rinsed of sand and debris, then spread on raised bamboo racks to dry in open air — never machine-dried, which keeps the fibre and colour intact.
