Hey there Outlawimmortal, I think you should be ok mate.
Just as everyone else has said.
Keep it simple and tell no one.

Just stick a few plants in pots in your garden.
That is defo not Sophisticated :P

But yeah if you do have Light/Fans/Scales/Cash/Nutes and all other brilliant paraphernalia, chances are your in the deep shit..

If you get caught expect a hefty fine and maybe some community service
But hell everyone should give back to the community anyway.
Look at it as a win win situation.

And if you ever smell the bacon knocking on your door... Get ready to eat some sexy green

Peace.
