@bluntley420 I disagree with what you said.
Regular seeds and feminized seeds have differences about them. The biggest difference of regular seeds and feminized seeds is that regular seeds your not garunteed feminized seeds, 1/2 or less then 1/2 coups be male and the rest female or you can get lucky and get all females when coming down to regular seeds to help increase chances of females keep temps stable (77 degrees) and roughly 65-75% humidity) along with shorter light cycles can help this as well such as 16/8 or 14/10.
Feminized seeds on the other hand you have 0 chances for males regardless you can get a hermie which would be from being stress induced but when you see feminized that means no males.
@KRoNiK yes they should be all feminized plants
