Gardening doesn’t get any ‘greener’ than this! Here’s a DIY vertical vegetable garden that uses recycled plastic bottles as planters. And is equipped with automatic watering system, which is powered by solar panels and a wind turbine!

DIY Self Watering Vertical Garden

The vegetable garden is composed of 72 large water bottles cut in half and installed upside down on a wooden shelf. This method enables you to plant large quantity of produce in a very limited space.

There are two water reservoirs. The first one collects rainwater. It’s situated on the side of the green wall, and is composed of eight barrels each can hold 200 liters. The second reservoir located under the wooden shelf collects excess water from the planters, and is made from repurposed street barriers.

The water is pumped from the reservoir into a PVC pipe with holes on top of the green wall. Water then drips to planters and the excess goes back to reservoir creating a complete cycle.

The water is circulated using 12v pumps which is powered by a turbine and two solar panels. The power is stored in a car battery. To maintain the right moisture the watering system is regulated by a timer.

Any ideas on how this system can be improved?
