I got a freebie seed in a shipment that has a tendency to hermie toward the end (takes a bit longer to finish up, that's when it gets all freaky). I keep an eye on "her" and pick the little guys off as I see them. They are pretty minimal - maybe five little sprouts on the whole plant - so I haven't really had any issue getting anyone else pregnant. I am a fan of coletrain smoke, super smooth and jazzy, and heavy production, so I don't mind the extra work and continue to clone "her." It's all part of the life, I suppose... I love my freaky lady!
I'd say give it a go, watch REALLY closely, and then when you are trimming see what you get. If you get five seeds or less, good job!
