DIY urban farming

Growing plants on my roof is like trying to grow plants in space. For a long time I've been planning to build a green house on my roof in San Francisco. I've tried growing a few plants without the protection and they last two or three days before the wind sucks the life out them. So I was excited to see this new DIY approach to farming that uses a hydration system to grow plants in your windows.

The plan seems limiting at the moment, but what if we adapted the idea slightly and created a facade for a house that enabled plants to grow up the entire front of your house or apartment. With the use of hydroponics and a protective, greenhouse like cover I can see this as a real possibility.
