I'm guesing they would have to get a warrant to come search your house. If you do call the cops and be like "Hey. my neighbor is growing weed.", they will more than likely kick your door down, shoot your dog, eat the rest of your donuts, and confiscate your lights and equipment and probably accidently shoot you in the ass.(Happened to this guy's gf, when he got raided. Swear to God.)

On the other hand, keep it safe, keep it clean, and don't even get a speeding ticket and fly under the radar you should be ok. And whenever you meet a cop face to face, ask him how it is going, crack a joke, be friendly, go to town meetings, act like you care and be an upstanding citizen, they won't think twice.
