Best Once Human Acid farm

In Once Human, Acid is a very important resource as it is used in a lot of crafting recipes and one of the more predominant materials involved in crafting specialty Ammunition that can deal with end-game bosses. We’ve put together the best Once Human Acid Farms so you can get as much of it as you may need for crafting.

Best Passive Once Human Acid farm

The best Once Human Acid farm involves setting up a passive farm at your base that will automatically generate Acid for you to use. Primarily using Water Pumps, this passive farm can generate 288 Acid per day for a mere 108 Watts of power.

It’s important to note that Acid can only be created in polluted areas, so make sure you are in one when setting up the passive Acid farm. If you see a number fluctuating on your character’s back, you are in a polluted area. Here’s what you’re going to need to build this passive Acid farm in Once Human:

• 10 Water Pumps
• 1 Osmosis Water Purifier
• 1 Fermentation Barrel
• 108 Watts of Power
• Built in Pollution Zone

Build some Advanced Hydraulic Generators to create power for your base, and then construct your 10 Water Pumps. Make sure you raise the elevation using the scroll wheel when placing the Water Pumps so you’re not pumping groundwater and rather dirty water which is why you are in the Pollution Zone. Each Water Pump you build requires the following materials:

• 25 Steel Ingot
• 20 Carbon Fiber Fabric
• 20 Refined Parts
• 20 Standard Parts
• 20 Electronic Accessory
• 10 Watts of Power

Make sure all the Water Pumps are dumping into Water Buckets which is where they can be collected. From here, connect the other side of the Water Buckets to an Osmosis Water Purifier. The Osmosis Water Purifier will convert the Polluted Water into Impure Acid.

You’ll have to manually collect the Impure Acid out of the Water Purifier, which you then place into the Fermentation Barrel. A completely filled Fermentation Barrel will generate 4 Acid every 20 minutes, making this passive base the best Once Human Acid farm!
