I managed to grow a ginger plant by placing the root into a pot of sand and compost with added fertiliser and placing it in the hottest part of the conservatory, which was against the south wall below the level of the windows. The pot was wide and shallow.
I used a root from the local grocer, washed it several times in warm water over the course of a day, planted it and sprayed it with warm water every day. It will rot if over watered and die if cold water is used. It seems to like heat but not sunlight. It was shaded from the sun by a wicker waste paper basket the year it grew best, so about 50 percent shadow.
Use a heavy pot as it can grow quite tall.
