height isnt important in the amount of bud ur left with and it depends on strain and how much light the plant was getting though remember in a forest youl need to make sure its growing in a patch where lots of light can get at it all day and even if your plant does germinate theres a 50/50 chance it wont be a female so you should buy 10 and make sure you dont buy an indoar strain if your growing outdoar it should tell you in the description of the plant anyway and put them about a half inch down in the soil
