From Unofficial Stationeers Wiki
Potatoes can be grown in hydroponics to yield 3 x Potato.
Provide water into piping (currently temperature of water doesn't matter, as well as other piping contents) and CO2 in atmosphere at 15oC-50oC Min ~7.7Kpa. The plants will produce oxygen and heat which you will need to remove.
- In Portable Hydroponics Potatoes yield only 2 x Potato.
|Time To Fruiting||1.1 Days*|
|Edible By Chickens||No|
Science: *These little guys are not like solar panels and only need sun on their specific "tile" to grow.
