Just space them out. I have that damn chopper overhead here every season and every time I'm freaking out and pissing my pants
I grow mine along with alot of brush that keeps them covered, I keep them spaced out and always tie them down if they get too tall. I usually end up growing about fifteen and harvesting atleast ten ladies and never have any trouble. Just make sure that you don't wear a groove in your path so they can't see that and make sure that the dirt does not look fresh. Keep things undercover and never tell a soul! That is always the biggest downfall,it's not the cops or the choppers or the nosy neighbors...it's the loose lips and the pissed off ex friends or ex girlfriends and boyfriends..I know it's hard..trust me! But in the end you can tell them and share with them and be safe! Just don't let them know where the stash is!
