Pull out your Multi-Tool to harvest them from the plant. Do not worry about running out because these resources grow back quickly on the stem, meaning you can revisit the exact same plants to collect more later.

For quick harvesting, head directly south of the Life Pod to find a cluster. You can also drop straight down into the trench located right underneath the Life Pod to find another patch in Subnautica 2.

Where to Get Copper

Copper rests inside tunnels and under rocky overhangs. Swim into sheltered spots or search beneath large stone arches, as these covered areas contain plenty of deposits.
