Subnautica 2 Farming Guide — Growbeds & Best Plants

How to Get the Growbed

Scanning Growbed fragments at the Alien Ruins Research Outpost

The Growbed blueprint requires scanning two fragments, both found at the Alien Ruins Research Outpost, located 1,275m east of the Lifepod. Both fragments are right next to each other, so a single visit is all you need.

How to Farm Plants

Place the Growbed on your base’s roof

Best Plants to Grow

Harvesting Acid Raion for batteries and first aid

Plant	Why It’s Worth Growing
Acid Raion	Produces Acidic Raion Pouches and Medical Gel Sacs for Batteries and First Aid Kits
Cradle Shootroot	Grows Lucifer Rotsacs for Rubber and Grease. Cut for Fibrous Pulp for Fiber or Biofuel Blocks
Macaron Sponge	Good option for harvesting large amounts of Fibrous Pulp

Tip: Avoid planting the Mimic Pylon — it’s purely cosmetic, cannot be harvested, and will shock you.

The Bottom Line: This is the kind of mechanic that seems obvious after you know it, but the game sure as hell won’t tell you upfront. I learned most of this the hard way — by drowning, starving, or getting eaten. The systems in Subnautica 2 are deep but fair. Once you understand how they work, survival stops being a struggle and starts being a strategy. And that’s when the real fun begins.
