The conversion period for a seaweed harvesting location is six months.
The conversion period for a seaweed cultivation unit is six months or a complete production cycle depending on which period is the longest.
The seaweed may only be sold as organic once the conversion period has ended.
It is not permitted to produce conventional and organic seaweed in parallel. During the conversion period, your entire company switches to organic production. Another possibility is to start a new company specifically for organic seaweed. The organic product flow must be completely separate, legally and physically, from the conventional product flow of your other company.
