I know EXACTLY what you are talking about as a neighbor got a visit and had 1 extra plant (it was 5" tall, and I think the variety was "cannibus smurf") he had 37, should have had 36 and they took everything, including all of his indoor equipment, irrigation stuff, fertalizer, barrels, water hoses, stakes - everything even though it was not in operation.

My advice is play exactly by the rules, and don't try to cheat. You'll only be sorry!
