When I buy a house, I plan to buy one with big walk in closets. In one of the bedrooms, im gonna turn it into a home office, but take off the molding around the door to the walk in closet. Im gonna put a big wall unit style bookshelf to hide the entrance to the door so it sits flush with the wall. I could have ~25 square feet of growing space that is totally hidden to the outside world. Have a 6 pin # key to the office door....people could know it, but any unfriendlies wouldn't.

Ya know, if you buy ~13k dollars worth of solar panel stuff, you can create nearly 2,000 kilowatts of constant power for free. If your usage is low, you can actually watch your 'pay' meter spin backwards, as you sell overflow power back to the electric company.
