Shelfponics is a combination of vertical farming and hydroponics. The idea comes from the GardenPool project in Arizona, but Shelfponics does not need a warm climate. Trays and racks could be set-up anywhere inside where sunlight reaches.

So I was looking at an unused corner of the Garden Pool when I had an idea: vertical growing. It was a small area with about 78″ of vertical height, perfect for vertical growing. We generally used the corner to store unused buckets, aquariums, or small starter plants in soil.
The next task was to find a simple solution for vertical growing. What was found was a bookshelf that was used to store tools and miscellaneous GP stuff. I took down the bookshelf and installed a simple plywood shelf elsewhere to take its place. While examining the bookshelf I noticed that the shelves could be snapped-in upside down. This would make a perfect tray Ebb & Flow system. Over the next 9 months we would experiment with and perfect what we have coined shelfponics.
