I agree, rules 1-10 don’t tell anyone!
That being said, in most places more plants=more trouble. So always keep that in mind.
Another thing that probably wouldn’t hurt, is to build/buy some sort of stealth grow box. Options are limited on the web, and depending on how paranoid you are, big brother could always be watching. Grow tents are easy, but having one anywhere in your home is very conspicuous.
Building one doesn’t require a lot of skill, but being handy can really change the dynamic of your box. And a little ingenuity can go a long way. I’ve seen them in pc towers, cabinets, converted furniture, speakers, and lots more. A Google search should give you lots of options.
