What makes sweet potato plants form tubers?
My plants have been damaged by hail, but I think will continue to grow. Do they flower before they produce tubers? Or is it light or temperature related?

Sweet potatoes are true roots not tubers. As the plant ages it uses the roots roots as storage. They usually begin storing when when about two months old and will continue until the plant dies. They are a perennial and will live until killed by frost. It takes about 3 months on average to form usable sweet potatoes. Many varieties never flower and for those that do has no effect on root development. They are tropical plants in the morning glory family and grow fastest at high temps and humidity.

Thank you! That helps.
We are having higher temperatures, so unless there is early frost I still have hope!

And I have a plan for the humidity for next year:
I will plant them in large Rubbermaid bins, but with drainage holes.
I will place these under the glass topped patio table.
Then I will use tape to make plastic walls around the table
? plastic shower curtains or the like.
If cold spells threaten----I can hang a shop light under the table
to drive off a few degrees of frost if needed.
I could place large pails of water under there too to act as a heat sink.

If you are talking about South Carolina, You can set plants from mid-April to mid June and expect a harvest. Southerners are not pressed for time like folks in the North.
