ya know i had that problem one summer 2many people knew and one night some came over and did a little pruning. so i bought a hammoc, some of them cheap womens pullcord incase of emergency sonic cherping things and a roll of heavy deep sea fishing line, and box of eye lags. i attached the eyebolts evenly around my yard at about ancle height. i set one cherper up around the grow one around my deck area, and another across the whole back yard in a crisscross pattern. so if the line was disterbed it would pull the pin on the cherper and i just slept on my hammoc armed the rest of the summer never had a problem again after who ever tried to rob me heard about the triplines and armed fat dude
