think about this. Say the chance is 50/50
if you plant one seed, you have a 50% chance of a fem.
if you plant two seeds you still have a 1/4 chance of getting two males
but it's also 1/4 chance of getting two fems

what i'm saying is that two seeds doesn’t guarantee anything
harris7 Reviewed by harris7 on . What determines a plants sex ? When does it actually happen ? What controls it to become a male or a female ? Im sure its a lot different than human birth but what actually causes a plant to become a male or a female ? is it just a luck of the draw ? Ive always wondered this. Especially now since I have a lot of equipment headed my way including the seeds. I just dont want a male, I want a female. Would planting 2 plants increase my chances of a female ? Thanks. Rating: 5
