@NYDon I live in the country…if this were me and I was concerned about this male pollinating any outside females…. There’s not many options unless you plan to WANT seeds and then there’s no reason to move him….
Options might include:
Moving the ladies inside in a controlled closed setting, treating it as surgery anytime you go from the male plant you’re changing clothes washing hands just being sterile
Moving the male plant more on a down wind side of your territory, and at least 3-5 miles away, this doesn’t guarantee anything but lessens a chance of pollen spreading against the wind right? Only thing is that a lot of pollinators travel on the wind and just might find your outside ladies after finding the male
Isolate the male or females in a greenhouse if inside isn’t a possibility
Like I say not many options but if you’re willing to take a risk then you can do what ya want….anyone growing outside knows this risk and if they get their plants pollinated then it’s their own fault NOT YOURS….grow happy and freely and LEGALLY homie
Note if you have the means time and resources male plants make the best hemp
