m0useanswered grow question 2 years ago If its a true hermi "both male and female separate sex organs" its not good to keep, it will pass on them weak genetics and the chances of it herming again is high. so not the best for crop yields.
If it popped a few nanners in late flower that's not as bad, the pollen from them is not normally all that fertile and its an average reaction to stress in plants. Some really nice strains do this and its excepted in some circles. I have had a handfull of plants make a single nanner, sometimes I spot it and others I don't, I know it was there because in my entire sealed tent grow I'll find like 2-5 seeds. Meaning it was very small in its effect.
If these are branded bought seeds contact the company "breeder" you bought them from and ask for advice or replacement. If breeders do not stand behaind their products they are not worth showcasing on here and wasting your time. Stay away from growers choice, GOG and Expert Seeds, they are the worst. Lots of other shity breeders out there as well but these one are the bigger ones,
