Fern Spore is a crop seed planted to grow ferns, harvested from wild ferns in nature. It provides no calories or nutrients, so it contributes nothing to the food-based XP multiplier, but it is compostable and essential for crafting Agriculture Research Paper Advanced. A practical tip: since ferns have no nutritional value, grow them only for their research use or as compost material, not as a food source.
The descriptive prose on this wiki is written by a large language model — but it runs entirely on local, self-hosted hardware: a Gemma 4 E4B model on a single NVIDIA RTX 4070 in a home Unraid server.
Nothing you read here was generated by a commercial cloud API. The game data itself is pulled live from the Eco server; the AI only fills in flavor and gap text. Like any web server, this one keeps its own request log — including visitors' IP addresses — purely to run and improve the site; it is never sold or handed to a third party.
This wiki is one face of a larger Eco mod: Solomon, an in-world AI steward that runs the server's economy, posts help contracts, keeps a store, and answers players. The wiki reads the same live game registries and tools Solomon does — so the numbers stay true to the running world. Read more about the project →
