If it has little white hairs and it has round balls than its a boy If it has red hairs and the balls are more tear drop shape than it's a girl. nice plant though.
No actually that is false, a female in the beginning will have white hairs not red until its matured and ready to harvest.
if u plant let say ten seeds the first who show the symptoms of a male and are bigger than your other plants are most of the time a male This is like in al the nature things males stronger and bigger
