Oxygen Not Included Farming Guide

Updated 20 Oct 2026 Source Synthesized from published Oxygennotincluded guides; rewritten in original wording on 20 October 2026 By

Mealwood first

Mealwood needs no fertilizer and grows fast. It is the safety food that keeps a new colony alive.

Then fertilize

A fertilized farm out-produces mealwood but needs fertilizer. Build a loop with pips or a refinery so it never stalls.

Water the farm

Crops need water. Pipe it in and recycle what drains, or your food chain dries up.

Match the eater

Different foods suit different needs. Grow what your duplicants burn, not the prettiest crop.

Keep it clean

Farms hate germs. Seal the room and add a hand sink so sick duplicants do not spoil the harvest.

Build the farm

The building database lists farms, planters and pipes. Place them in the cool clean zone.

Use the critters

The critter database lists species like Hatches that feed farms. Ranch them to close the loop.

Store the surplus

A fridge keeps food from rotting. Stock it so a bad cycle does not starve the base.

Balance the diet

Mix mealwood with better food as you scale. A varied diet keeps duplicants happier and healthier.

Let critters help

Critters like Hatches feed farms and close the loop. Ranch them so the food chain runs on its own.

Chill the stock

A fridge keeps food from rotting. Fill it so a rough cycle does not starve the base.

Spread the plots

Grow a mix so one failed crop cannot starve the base. A spread of food beats a single big farm.

Frequently asked questions

How do I feed a colony?

Start with mealwood for quick calories, then build a fertilized farm for steadier, better food.

What is fertilizer for?

Fertilized farms grow faster and better crops, but need a fertilizer source like pips or a refinery loop.
