Since something is pollinating the ladies, until you find-out which plant(s) have the nanners, seeds will keep coming and they will be at at different levels of maturity upon harvest.
You'll have those big healthy brown, black or brown-black striped ones, yellow immature ones, and those annoying little popcorn ones that are impossible to find till they are exploding in your pipe.

A seeded plant also suffers in the yield department. A 2 oz cola can easily hold an ounce of seeds which are useless if from a genetic hermaphrodite. After stems and seeds are removed, perhaps 1/4 to 1/2 oz of smokable cannabis could remain. Not a very good return on investment.

Herms affect all the ladies in the room, so you'll have to decide whether or not it's worth it to just start over.

Whatever you do, no more 'virgins' in the flower room until room is free from pollen.
