Find other plants that could mask the smell and plant tons of those. search for strong smelling weeds and flowers and do what it takes to get your hands on them. also, sometimes if people who already KNOW you are growing they are more in tune with the smell because they already know its there. Did he already know? Honestly, myself, I don't let anything wreck my grow. I do whatever it takes and run with it 'till its done or it gets cut down. There's a weed you could find at the river that smells like black licrish, find it and dig it up and keep it alive and bring it home and feed it good to make it stink. the more you get the more effective the smell will be. Hope that helps.
