Fibercorn is plant added by the Ideology DLC a way to harvest wood if you disapprove of trees being cut down.

  • Light

    Most plants typically require at least 51% light to grow.

    Decorative Plants typically require at least 30% light to grow. Fibercorn oddly falls into this light requirement.

    Most artificial light sources only provide 50% light.


    Fibercorn is an labor inefficient source of wood compared to most trees, coming 10th of 15 in terms of wood per work, including the mostly decorative bonsai tree. How poorly it performs depends partially on the biome in question, and consequently the other trees available for sowing. For example, fibercorn offers only 42% the wood per work when compared to teak trees, but 123% when compared to the saguaro cactus, the only tree option in extreme deserts.

    In terms of space efficiency, it is similarly lackluster. Fibercorn's low yield is partially makes up for a low wood per day per tile by not requiring a 2x2 space to grow like trees do. This again places it 10th of 15 for space efficiency.

    Despite this, fibercorn has a number of benefits over trees that can make it exceptionally useful in certain situations. It requires no skill or research to plant, and it matures quickly. It can be grown indoors, and unlike most plants can grow under the light of a torch or standing lamp - this similarly means that a field of fibercorn can grow year-round, while a grove of trees will stop growing during particularly hot or cold seasons. On maps with little soil it can be grown in hydroponics basins, though it gains almost none of the fertility bonus. It can be planted in one-row strips when necessary, allowing far more flexibility in field shape. Finally, for certain ideoligions fibercorn provides a reliable source of wood that doesn't incur mood penalties.

    Food Production

    Unlike actual corn, fibercorn does not yield any human-edible products.


    Fibercorns' raw product is wood, which has a market value of 1.4 silver. The refined product with the largest profit margin is a grand sculpture, having a 51.25%[1] profit margin.
