It started when our dad (we're in high school) bought an EarthBox® planter. We read in the sales materials that the United Nations was using Earthbox® planters to teach people in developing nations an excellent way to grow food. This sounded like a great project, but we thought it could be made even better by using locally sourced free or low cost recycled materials. That's what got us started.
Also, watering Global Buckets by hand become a BIG pain everyday so we explored ideas on how to automate the watering job using atmospheric pressure. Our system works great! This entire summer we only spent about 20 minutes dealing with water. Previously, we spent about 10 minutes a day. Using some engineering and physics to create wonderful efficiencies was the most rewarding part of the project.
