Solar Decathlon: Plant rack

One of the houses at the Solar Decathlon had this great plant rack and watering system.

The full rack.

The watering system is just a drip hose run back and forth at the high point of each pot.

Come on, Dad. You've got enough scrap metal around the farm. You can whip out one of these.
