there is a common misconception that females only produce seeds under hermaphrodite conditions.. Sometimes if you grow big enough amounts they will have a very small amount of seeds and it has more to do with the female wanting to reproduce. But for example from 16 ozs I got about 4-5 seeds and they were feminized and not hermy. and from 11 oz I got 3 seeds and I only 1 was viable... But you get the idea.. With enough buds they may be the odd seed or two but if there was lots of seeds then it's more of a case of hermy..
Did the guy you bought it from grow it? otherwise, you have no one to ask..
you'll know if you keep it under 15+ hours of light and it starts to bud out on you.. it is an autoflower :)
good chance that seed is tarded, but looks like you may have gotten lucky. Still a really good chance it herms out on you..
Good luck with your bag seed. Most are the cause of a plant hermaphrodite. Which usually passes on the same genes. This is why feminized seeds are the go too choice now. Why fret putting work into a plant you won't want! Happy growing!
You can not know it now, you have to wait about 1 month. If it blooms regardless of the light period, it is a auto, if it continues to grow, it does not.
