Cannabis sativa is a dioecious plant.

Those who grow it for its psychotropic properties have in recent
years developed a style of growing called "sin semilla" (without
seeds). This requires identifying the sex of seedlings as they flower
and promptly removing all the male plants.

Why that way around? Why not grow only male plants? Are the female
plants better?

Can't one just remove the flowers?
