Collect Plant Oil from Greenhouse Barrels
Plant Oil supports polymer crafting, and harvesting existing barrels can supply it before an aboard Canola operation is ready.
Blue Plant Oil barrels at Greenhouse Towers and other garden variants.
Repeat at other garden or greenhouse sites that have barrels. Collected oil is salvage; no respawn cycle or guaranteed barrel quantity is established.
Stop once you have enough oil for the planned polymer or crafting batch, or when the accessible blue barrels at the site are exhausted.
