Being able to grow our owl algae would be very useful. Both salt water and fresh water types would be useful and give more of a use for fresh water on the ship. Maybe multiple types of algae to give different organics, and a type that gives more fuel/petrol. It would take water/salt water, need sunlight, and a sample of the algae you want to grow to make it start.

This is a very nice idea.
lethal raft
Small, medium, and large versions, able to take saltwater, or freshwater for faster growth
Plus multiple types of blooms, for different resources, including one for specifically fuel/petrol
ALSO if we pump co2 into it, it gets another boost, so the waste co2 the ship makes can be used

I know 'owl' is a typo for 'own' but now Im picturing some sort of algae esque owl creature that comes out of the water at night, like a biological variant of the bee/beetle robot mobs
