I'm sure if people here were to answer you'd get the benefits from both sides.
I only use the fem. seeds for now cause I grow in soil and I got it inside my brain that they will all be female, but they can herrmie if they get stressed.
Others like regular seeds grow them out till they show sex and weed out the males.
Since I grow in soil,,Fox farms and it is expensive for me I Like the thought of Fem. seeds and taking really good care of them not to stress em', There are no guarentees just better odds IMO.
I'd say go Fem. if you never grew before.
