Slowly as possible but realistically about 7-12 days. If you can bend a stem and it breaks easy you have to throw them in cure before they dry out too much. In my dry room which holds 68-75 temps and 55-70% humidity I can go 14 days before the stem can snap when bent.
Humidity control throughout the grow is important, but in dry and cure it is really important. You need to find out what humidity range your room is. You want nothing under 50% in dry, nothing under 60% in cure.
