male pollen will travel very far so it would be to hard to control but dont worry you will have time to kill the males before they break open and pollinate your females. I would have your plants at least 5-6 feet apart and no more than 6-8 per plot in case it gets found. I have been using Off insect repellent around the plant and chili powder mixed with water in a small spray bottle and I spray a light coating on the foliage of the plant this has kept bugs and animals from fucking with my shit. good luck
