Its unfortunate. The herms are really a problem that we created for ourselves during the dark years. No internet, knowledge had to be passed around hand to hand. Many people used herms to make femmed seeds back then, amplifying a genetic flaw that we all pay for now. Sometimes you can work a strain several generations before the dreaded herm gene pops up, and SHOULD end the project. Many times it doesn't, too much time and money invested.
Also, many of the big name photo strains are herm prone. Bringing them to auto brings that gene along too.
