Oxyfern is a non reproducing plant that converts Carbon Dioxide Carbon Dioxide into breathable Oxygen Oxygen (the rate seems related to the air pressure).

Ratios

The Oxyferns have quite similar gas conversion rates to the Duplicants, however they are about 3.2 times slower, and produce slightly more Oxygen than duplicants consume, which makes it impossible to cleanly match their number to the number of duplicants, leading to either Oxygen or Carbon Dioxide runaway overproduction.

Oxygen
(g/cycle)
Carbon Dioxide
(g/cycle)
Duplicant -60,000 +1200
Domesticated Oxyfern +18,780 -375
Ratios
(plants per duplicant)
~3.19 3.2

Domesticated Oxyferns convert about 98% of Water to Oxygen, which is still 10% more water-efficient than Electrolyzer (88% Water to Oxygen), with the additional cost of 4 kg per cycle Dirt.

As with any other plant, wild Oxyferns produce four times slower compared to domesticated ones, however they do not require Water or Dirt.

Growth

Oxyfern requires temperature range of 0 °C to 40 °C. It requires air pressure of 25 g to 10 kg, and Carbon Dioxide atmosphere. The plant has no growth cycle.

Domestic Oxyfern can be planted in a Planter Box, Farm Tile and Hydroponic Farm. It requires 4 kg per cycle Dirt and irrigation of 19 kg per cycle Water.

Tips

  • Note how high their pressure range is; unchecked Oxygen or Carbon Dioxide production might eventually overpressure your base.
  • Oxyfern Seed is sometimes offered as a Care Package. There is no other way to increase amount of Oxyferns on the map.
