Learn how to unlock the Metal Farm in Subnautica 2! Our guide covers the blueprint location in Root Canyon, crafting materials, and how to farm infinite Troilite and Atacamite.
The Metal Farm is a device that creates mineral deposits over time. Place a single piece of raw ore inside, wait for the timer, and harvest the metal with your Sonic Resonator. The ore you placed is not consumed in the process.
It is one of the most important structures in the game, and since Troilite and Atacamite are very rare, this is the only reliable way to get more of them.
Harvested from Mineralized Clinker deposits near the Metal Farm remains. Look for greenish piles on the seafloor with dark square crystals. Mine with the Sonic Resonator. Yields 1 to 3 per node. Very scarce. Collect as much as you can.
Axum Bacterial Culture
Found directly in the yellow glowing pools. Look for a small cage against the glowing background. Break the cage to collect it. There may be as few as five in total. Their only use is for building Metal Farms
Atacamite
Found near the Alien Ruins area, in and around the zone with the Angel Bloom Adaptation and the giant turbine. Dark obsidian-black spiky deposits. Mine with the Sonic Resonator.
Tip!
Build a number of Metal Farms before spending Troilite or Axum Bacterial Cultures on anything else. If these run out, you might not be able to craft another Metal Farm.
How to Build a Metal Farm
Metal Farm Recipe
x1 Mangalloy Ingot x1 Axum Bacterial Culture
After obtaining the Metal Farm blueprint, make sure you have Atacamite, Titanium, and an available Axum Bacterial Culture ready. In the current early‑access build, the number of Axum Bacterial Cultures you can harvest is very limited.
Step
What to Do
1
At a Processor, craft a Mangalloy Ingot using x1 Titanium Ingot, x1 Atacamite, and x1 Troilite.
2
Equip the Habitat Builder and open the Cultivation tab. Select the Metal Farm.
3
Place the Metal Farm on a solid surface near your base or on the roof.
4
Connect it to a power source. Each Metal Farm consumes 20 power. Build Hydroelectric Turbines or Reactors to support it. Use Power Transmitters if the farm is placed further from the base.
How to Use the Metal Farm
Step
What to Do
1
Interact with the Metal Farm to open its storage.
2
Select the material to be farmed and wait until the timer reaches zero.
3
Once the timer finishes, use the Sonic Resonator or Feedback Resonator to harvest the resource. The timer will then reset for the next harvest cycle.
Note!
Always harvest the grown resource before touching the input slot. Removing the ore during the farming process or before harvesting will reset all progress.

Having multiple Metal Farms running is the most efficient way to maintain a steady supply of rarer materials. Since each farm only needs one input ore and that ore is not consumed, a single piece of Troilite, Atacamite, or Conduit Crystal can be used to produce resources indefinitely.
