🥕 Carrot
Hardy and drought-tolerant; sweeter after a touch of frost.
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, 30) − 4), and Carrot is ready when that total reaches 950. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.
| Base temperature | 4°CBelow this, the plant accumulates no growing degree days at all. |
|---|---|
| Degree days to maturity | 950 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 7–27°CWhere it grows without stress. |
| Frost damage below | -4°CLeaves start taking frost damage below this low. |
| Killed below | -10°CBelow this it does not come back. |
| Heat stress above | 30°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 70–90 days |
| Yield per bed | 14 carrots |
Things worth knowing
- The first carrots were purple — the orange kind was bred by the Dutch in the 1600s.
- Frosted carrots turn starch into sugar as antifreeze, so winter carrots taste sweeter.
