ResourceGrower gives Subnautica: Below Zero players a new use for their growbeds: raising resource crops, including ores and Ion Cubes. ObscureWorldStudio released the beta on October 26 and warns that bugs may remain.
There are 25 resource seeds, with their recipes collected in a dedicated Fabricator tab. Each plant uses a large growbed slot and is consumed on harvest, so you'll need to replant after collecting the yield.
