January 1 to May 1, 2017

Current Challenge: H2GROW

We need food to survive. But food security is a problem around the world, and at home. Get creative as you design a sustainable living environment for aquatic life while growing food in this season’s Purple Plow Challenge!


This system must address the following needs:

  • Produce a plant based food source
  • Produce an aquatic animal based food source
  • The system cannot hold more than 20 gallons of water
  • A weekly documentation of water quality by pH


Success will be determined by

  • Harvesting an edible food product within 90 days or showing progress of plant and animal growth within the time frame allotted for your specific situation
  • Creating, constructing, and maintaining an environment that is suitable for aquatic animal life within 90 days
  • Posting a picture or short presentation showcasing the team’s prototype to social media using #PurplePlowChallenge.
