This study was carried out to investigate the optimum temperature and the cultivation period according to the different growth stages of Gastrodia elata (G. elata). The growth period for the indoor cultivation of G. elata is divided into four stages that require specific temperatures during the enlargement of the tuber. The optimum temperatures and cultivation periods during the growth stages of G. elata were observed to be 20oC for 30 days during the mycelial growth stage (MGS), 25oC for 120 days during the tuber formation stage (TFS), 6–24oC for 60 days during the tuber enlargement stage (TES), and 5oC for 30 days during the dormant stage (DS). The total cultivation period was shortened by 120 days in the indoor cultivation facilities by reduction of 30 days from the mycelial growth stage, addition of 30 days to the tuber formation stage, and reduction of 120 days from the dormancy stage as compared to the outdoor field cultivation. These results provide a basis for a growth model that permits year-round cultivation of G. elata.
