noob @ cloning, REVEG?

i have taken 2 clones off my super grape outdoor, the plant was 2-3 weeks in bloom and since the clone has rooted, but they still has the white hairs on top, i was wondering how long its going to take to fully reveg and grow.
i cant find a clear answer

and i have them in a 3 gal pot, the clones are small, i mean nothing special and the roots are already popping out the bottom of the pot, should i transplant again?

2-3 weeks to reveg

thanks^^^^^
