Well keep him down wind and hopefully whatever they have doesn't spread. It's never worth growing and trimming questionable plants. Who wants a freezer full of gross fucked up outdoor? It's gotta be a perfect crop just to be a decent smoke. If they start off sick. They don't usually make it worth the time to feed and trim. But beats the old days. With the feuding and the bad blood.
Anything that comes from a hermi will be inferior... From the seeds it makes from self pollination, to the seeds in other plants it has bread with. Plus even if successful at removing the pollen sacks the level of THC will be like the brick weed from back in the day. I'm not 100% sure those are hermied plants, but I'd go with "dude cut those down, bud from that plant will be like smoking catnip".
