Yep, I have 14 plants in my grow tent. 3 are hermies. I just give them a good look over every time I water and pluck what ever male flowers I find off. Yeah, I am going to find a few seeds here and there...no big deal really. It's not like I let a male sit in there and have its way with my ladies for an entire grow (or day for that matter).
I'd hold onto it if it's a good looking plant and only a mild hermie. Just pluck off the male flowers as they show (try to do this away from your other girls to cut down on chances of seeds). If it starts popping male flowers like crazy...kill it..more hassle than its worth.
