🆕 Updated for Eco 14 — “Garbage & Recycling” — this server and these numbers now reflect the new version. What changed →
  • Byproducts: nearly every recipe now leaves waste behind, so recipe pages list byproducts alongside ingredients.
  • Garbage & recycling: waste sorts from mixed garbage down to pure materials, and can be recycled back into stock.
  • Pollution has four kinds: acid rain, chemical, soil and heavy mineral, each settling into the ground differently. Pollution guide →
  • Modules reworked: upgrades are now Basic / Advanced / Modern / Specialty, one per slot, driving the same bonus system as talents. Module guide →
  • Fresh water: machines need it — water drawn from the ocean has to be desalinated first.

The character calculator has been updated for these changes. Read the garbage & recycling guide →

≈ base time for a fresh seed under perfect conditions. Real growth also depends on climate, soil, and fertilizer. Farming talents (seeding growth, fertilizer potency) can speed this up — effect varies, not shown as an exact number.

Target soil levels for this plant. Each number is the nutrient concentration (0–1 scale) to aim for: reach it and that nutrient fuels full-speed growth; below it growth scales down (half speed at half the value); more adds nothing. Raise nutrients by spreading fertilizer — see the Farming guide.

Best fertilizer: Hide Ash Fertilizer — richest in the Nitrogen this crop needs most.

Rainfall is a 0–1 scale. Outside the survivable band the plant won't grow or reproduce.
