What's the difference between auto flower n normal seeds???

Hiya was finking about buying seeds for the first time as I normally buy cuttings but I'm not a 100% shore there the real deal. And I was wondering what the difference is between feminized seeds and auto flowering seeds? And also which 1 is Best? Thanks.....

"Auto-flowering" is not a type of seed, it's a type of plant. They will flower, reguardless of what light period you have them on, whereas normal strains must be placed on 12/12(light/dark) to induce flowering. "Feminized seeds" are seeds that are bred to be all female, with no males to be sorted out and discarded.

Be careful if you choose to go with autos, because many of them don't flower automatically, like they're supposed to.

Thanks a lot is there any difference in the size of the yield?
