I grew 22 sativa's outdoors from seed gifted to me.
About a half were essentially female, with one or two having the old male flower; a quarter showed a few male flowers initially then (mainly) all female flowers; and the other quarter a few female first flowers then all male flowers. Talk about a dud batch of seed.
I concluded that the seeds I was given were probably created in a similar situation to my grow, with the hermaphrodite tenancy passed to all the offspring.
Fantastic smoke though
