Will this pollination work?

I got some fem auto seeds. Wondering if I get a male plant from bag seeds, will my auto grow seeds for future use? And what type of seeds will they be?

Yes, you can pollinate your auto, using a bag seed male.
However, what you will get for offspring will be a wide mix of photoperiod, and autoflowering hybrid seeds, with no way of telling which is which, until you grow them. The majority of the seeds will be photoperiod, though, that is the only certainty.

If you're looking to make more autoflowering seeds, I recommend you spend a few bucks, and pick up 5 regular autoflower seeds. Find a nice auto male from that group and mate him to one of your auto girls. Then all of their seeds should be autos, if that's what you're looking for.

If any of that sounds beneficial to you, than go for it, and good luck.

Thanks for that. Very helpful.
