Whats up man, I would see nothing wrong with growing near a cow farm, no suspicion..because your "getting in touch with nature" and also cows roam, no farmers, you should probably germinate the seeds before planting, place them between 2 paper towels and leave them somewhere dark for 3 or 4 days check on them to see root germination,plant them where they'll be camouflaged maybe near a bunch of plants or trees on the outskirt of the farm, check the soil to make sure its fertile enough.. go for it!--peace
