A variety of daikon
How to sow tokinashi daikon: Direct seed outdoors
Sun requirement for tokinashi daikon: Plant in Full Sun
A very long, white daikon with a green shoulder above ground that stays tender even when large. It grows very fast and is very slow to bolt. Used raw in salads, in soups, stews and stir-fries, and for lactic pickling; the greens are edible and nutritious. Scatter-sow in trays in autumn or early spring and transplant at the second leaves, 15 cm apart on the diagonal, or direct sow year-round except where winters are very cold.

What are growing degree days?
A plant grows with warmth, not with days. A growing degree day is one day's worth of useful warmth: how many degrees the day's average temperature is above the lowest temperature the crop grows at. Add them up from planting and you know how far along the crop is, whatever the calendar says.
Say that lowest temperature is 10°C. A day averaging 17°C gives 7 growing degree days. A day averaging 8°C gives none, as it is too cold for the crop to grow. That is why the same lettuce takes about 50 days in a summer and 90 in an autumn: it needs the same total warmth either way.
For tokinashi daikon, the FAO EcoCrop database gives a lowest growing temperature of 10°C and a shortest growing cycle of 50 days at its best temperature, about 450 growing degree days to a first harvest.
Where you've told us where your garden is, we use this and the weather there to predict when your tokinashi daikon will be ready to harvest. We don't use it for how long a plant lives or when it finishes: we go by what members have logged for that.
