Mostly genetic: Molecular biologist, chao quing lai states "about 60 to 80 percent of the difference in height between individuals is determined by genetic factors, whereas 20 to 40 percent can be attributed to environmental effects, mainly nutrition. This answer is based on estimates of the "heritability" of human height: the proportion of the total variation in height due to genetic factors.".

Mostly genes: Nutrition is rarely a factor unless you are nutritionally deficient. Males are expected to reach the average of both parents height plus 5 cm while females reach the average less 5 cm. There are no exercises or special foods to make you grow taller.
