as high as you let it, its a nearly pure sativa so it will probably get at least a foot of strech during its 12 week flowering period, if you want to grow this plant to its best potential you need too get it large so it has much energy to produce
, this is a plant that will reward you if you grow it big, but you can low srtess train any plant and make it short, like my b.b.cheese that would easily be 1.5ft, tall but its only 4 inches...
