I know that the DEA and other law enforcement agencies use helicopters and IR scanners to look for warm spots to bust growers. Anyone know how much you gotta be growing to raise suspicion. I’m pretty sure 4 or 5 plants wouldn’t be a problem. I keep hearing helicopters flying over my house constantly. I think it migh be Bush and his people flying in and out of his ranch cause I live really close to it. Im not worried though cause I dont grow, just intrested for future reference.
