a lot of folks seem to despise fem seeds and i'm not sure why.
i have a PPP fem seeds grow documented (first journal) and the current grow journal (both in sig) is regular Big Bud seeds and a fem PPP.
Now i guarantee someone is going to post something like - fem seeds are more prone to hermie.
Before anyone posts that - my current grow suffered severe heat stress and get this - BOTH Big Bud (regular seeds from bank - not fem) went hermie and the PPP fem did NOT! anecdotal statistically insignificant evidence, yes - but this is the complete opposite of what you'd expect from reading fellow posters fem seed opinions.
i have yet to get a male from a fem seed but i understand your chances are about 1 in 10 being male/hermie. not bad considering the alternative.
If you plan on breeding then fem seeds can have issues and obviously it would be better to just take clones from plants you like - fem seeds or not. But if you grow from seed (like I do) and do not breed - then fem seeds are a viable option. This is my opinion and experience.
Never had any trouble with my feminized Blueberry seeds. All germinated just fine, and even with some lower temperatures and higher humidity, never had any females go hermie. I agree with email468 that fem. seeds probably aren't the best for everybody, but I've had no problems with the feminized Dutch Passion seeds I've used. Peace.
