best bet dont tell anyone if people do know your starting tell them u changed your mind, really from my experience dont trust anyone %100 especially when it could end u up in jail
a few peps know bout my grow but there people that sell stuff anyway so wouldnt ever dream of even havin a conversation with the feds
but seriously if no1 knows then youve got no way of getting busted unless you tell someone that tells someone and so on
oh and id get rid of your pic if thats you on your aviater as now anyone can see who you are an know your gonna grow
good luck man
