🌽 Sweet Corn
A sun-hungry summer headliner, pollinated by the wind.
What the numbers mean
These are the actual parameters this game runs on. Growth is driven by growing degree days: each day contributes max(0, min(mean temp, 34) − 10), and Sweet Corn is ready when that total reaches 900. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.
| Base temperature | 10°CBelow this, the plant accumulates no growing degree days at all. |
|---|---|
| Degree days to maturity | 900 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 16–32°CWhere it grows without stress. |
| Frost damage below | 2°CLeaves start taking frost damage below this low. |
| Killed below | 0°CBelow this it does not come back. |
| Heat stress above | 36°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 65–85 days |

Things worth knowing
- Corn is humanity's most transformed crop — its wild ancestor teosinte has an "ear" the size of your pinky.
- Sugar starts turning to starch the moment an ear is picked — "boil the water before you pick the corn".
