Food is one of the basic Resources in Surviving Mars and is necessary to keep Colonists alive.
A colonist will eat when visiting a Grocer, Small Grocer, Diner or Mega Mall to satisfy one of the only two interests that are shared by all Colonists, Food. When hungry and unable to eat from one of those buildings Colonists will just take Food from a nearby stockpile, although with a −3 (unprepared meal) penalty to Comfort.
If unable to eat for more than 36 hours, a colonist will starve and lose 25 health per day.
Crops are the main way of producing Food. They also produce small amounts of Oxygen. Crops require constant Water and if there is a shortage the crops will start to decay, decreasing their harvest. Water requirements can be reduced by 50% with the Dry Farming Breakthrough.
Hydroponic Farm CropsEdit
Each Farm has a Soil Quality rating that encourages crop rotation. It starts at 50% and can be increased or decreased depending on the type of crops planted. Performance scales directly with Soil Quality and the Farm gains +50 Performance at 100% Soil Quality and -50 Performance at 0% Soil Quality.
Each Farm in a Dome can increase its Soil Quality by +1% each Sol up to 90% maximum when all the Crops are turned off. No workers, power or water is required for this. This works on Farms if the Dome is also turned off.
|Crop||Growth time (Sols)||Water consumption||Optimal harvest||Optimal harvest per sol||Oxygen production||Soil Quality||Requirements|
|Cover Crops||5||2.4||12||2.4||0.3||+40%||Utility Crops|
|Giant Potatoes||5||2.4||80||16||0.3||−10%||Giant Crops|
|Giant Wheat||2||1.6||23||11.5||0.3||No change|
|Seed Crops||5||2||5||1||0.3||+10%||Martian Vegetation|
|Curetatos||5||2.4||10 Cures||2 Cures||0.3||−30%||Wildfire Cure|
|Cactus||0.04||1||1||25||1||No change||Sample Mods|
|Crops meat||3||0.3||30||10||0||−10%||Sample Mods|
Open Farm CropsEdit
Each Open Farm has a Soil Quality rating determined by terraforming that can be increased or decreased by the grown Crops. It does not affect the harvest but it limits the Crops that can be grown. Researching the "Resilient Vegetation" breakthrough will halve temperature and water requirements of all crops.
Animal Breeds are a second source of Food available in from the Ranch and Outside Ranch buildings from the Project Laika DLC. Animals require constant Water and Oxygen and if there is a shortage the animals will start to die, decreasing their harvest. Unlike other food buildings, ranches do not benefit from being worked by Botanists.
