i have a very nice and potent PurpleWreckOG photo plant that has a tendency to hermie, but it's so good! i keep it around but i have to check it every few days for male parts.
i spray it down with water to help de-activate some pollen, and i just pull off any male parts that i find. i usually end up with a few seeds from each plant, but it's great smoke! not sure how long i'll keep cloning it, it is kind of a hassle to babysit it all the time.
yeah, just prune off the male parts and ride it out. you may get a few seeds, but you should still get good smoke from them.
