Depending on where it is. If it was like a seedling, they'd probably dust whatever could hold fingerprints that the grower would have touched, and left.
If it was a larger plant, they'd probably wait for you to come around and build up evidence against you and you wouldn't know it until you were fucked.

If it was 5+ plants they'd arrest you on the spot.

My advice:
Grow in your neighbors yard somewhere. Trust me, theres some spots around. I successfully grew two three foot tall plants in plain view of more than one house, and just because the people were old, got away with it.

How big of a deal would this be? i live in united states, i know its a little diffrent from state to state, but what would the cops do if they were tipped off or just found 1 mj plant? what would they do, chop it down and leave or dust for fingerprints. how far would they go? im getting real paraniod. i never been this paraniod ever. have the cops ever found your shit?
