1 - Me.
Never tell anyone! I once told a friend about my plants outdoors cause he would eventually see them from the window. He swore he wouldn't tell anyone. Well he eventually told another friend who has a big mouth. Then the big mouth brought it up in front of a guy who is a bit seedy. The seedy guy then told 2 other guys who ripped off about 1.5 pounds of outdoor satvia and dobbed me into the police as well. The police then came around and seized several ounces of already harvested indica.
Thats why you should never tell anyone.
