Plant a piece with buds just under the surface of a wide pot, hold it warm plus add a lamp once shoots appear.
The short answer
Ginger wants warmth plus moderate light. University of Vermont Extension advises a wide pot plus a warm spot of 70 to 80F, with sprouts in 3 to 8 weeks. UC ANR notes ginger needs 2 to 6 hours of direct sun a day, so a grow light fills dim winter days.
