Thanks for the replies everyone. I have two original copies of my recommendation and will check into getting one laminated. I've also instructed my wife (the only other person who knows about these plants) on where they are and exactly what to tell any law enforcement officers who have any questions, should anything happen while I'm at work.

I've also secured the perimeter, plugged up some holes and upped the camouflage with other flowering and fruit bearing plants. If you did manage to get into my grow space, you'd have to do some pretty good poking around before you noticed anything.
