A 20 litre water bottle as a self-watering unit to grow vegetables

Posted on May 6, 2008

Tanushri and Shifali, the 3rd year product-design students who were working on some self-watering systems for PetPuja, designed an extension of the Bottle Biology design. A 20 litre water bottle (which many of us in India use as our primary source of drinking water at home) is cut into half and the top part is inverted to become a container for the soil. The lower part of the container stores water and wicks flowing out of the neck of the inverted upper-half of the bottle draw up water from it and keep the soil moist. In the second photograph below, you can actually see the tiny fenugreek/methi plants!
