Yea I don't know the process of how they make their fems but I have always seen they had issues when it can to fems. Some do better than others but when they first released SinMint Cookie fems lots of reports on herms. One reason why I think hey stopped on fems for a while but when it comes to Cookies you better be prepared for herm issues cus it can happen especially with the crosses straight to the cut and not f2 etc and worked.
I didn't see any nanners or balls on my SinMint Cookies regs but one had to have a nanner as I found seeds a couple in a few plants around SinMints and in SinMints themselves but it wasn't an issue for me as I never saw any balls and of course I'm not a breeders trying to sell seeds
