lol. I love the suggestions.
I might try fixing it up so they can't see inside plus putting a sign on the roof would be good "No weed here asshole". If there was a way to shorten "If you can read this you are trespassing, even if you're police" that could be another good one.
Please tell me you at least flipped them the bird? Maybe you should install a bunch of heat lamps and such in there and see if you get raided.
Unfortunately I didn't, although that would be a good one if I have a camera ready. I'll flip them off and make sure I don't get on camera doing that and when they go to flip me back it might get on camera.
Oh yeh, I'm not growing anything either. If I was, it wouldn't be in the greenhouse. A greenhouse seems to be a good distraction, though
