Aquaponic System Study Model Fluorescent Grow Light Pump and Particulate Filter Plants Grow Bed Grow Medium (gravel) Drain Fish Tank Water Test Kit Fish Food Grow Light Timer This proof of concept model was set up to learn how the system works first hand. It uses goldfish, and we are currently growing lettuce, broccoli, peppers and tomatoes. farmphilly an urban agriculture project
  • 6. How Aquaponics Works Fish are fed food and produce Amonia rich waste. But, high levels of the waste substance is toxic for the Lettuce- Harvestable in 60-90 days fish. Bacteria breaks down this Amonia into Nitrites and Nitrates. Bacteria is cultured in a particulate filter and/or a grow medium. Farmer/Consumer -Feeds fish and Plants take in these Nitrates maintains the as nutrient. Water being system pumped through the grow -Receives two bed gets filtered by grow crops from one medium and plant roots. system. Water is then returned clean for the fish. Very little water is wasted in the process. Talapia- Harvestable in about 200 days farmphilly an urban agriculture project
  • 7. Adavantages of Aquaponics Hydroponics + Aquaculture = Aquaponics Hydroponics systems grow plants without soil. Aquaculture creates a habitat where fish can live and thrive. Aquaponics takes the best of both systems and combines them. Uses Much Less Water Aquaponics systems use about 20% of the water that it takes to grow using traditional means. The water is recycled so that there is no waste in the form of runoff. Farms Plants and Fish If an edible fish, such as tilapia, is used to fertilize the plants, then the fish can be eaten as well. This creates a much larger yield than plants alone. No Added Fertilizer As long as the fish are being fed, there is no need to add fertilizer. The fish can be fed with the worms that live in and eat compost, which can greatly bring down the cost of fish food. Grow Almost Anywhere Aquaponics systems can produce food almost anywhere. They can be utilized indoors, or in places where the soil can not support plant growth, such as brown fields. farmphilly an urban agriculture project
  • 8. Project Statement As a part of the UArts FarmPhilly initiative our goal is to utilize aquaponics to grow food in an urban setting. Given Greensgrow’s current involvement in hyrdroponics and aquaculture, an opportunity for design exists in an aquaponics system. This design affordance allows for the integration of a repeatable and expandable system that gets food to people, educates and raises awareness. farmphilly an urban agriculture project
  • 9. Why Aquaponics at Greensgrow? Fits into Greensgrow’s mission Aquaponics continues to develop exciting, affordable and workable plans for growing food on land that was once deemed un-usuable. Promote Produce Aquaponic lettuce would promote awareness and interest in alternatively grown lettuce. This interest translates into increased demand and sales of hydroponic and aquaponic lettuce. Sale of fish In addition to providing nutrition to the plants, revenue can be generated by the sale of fish at the end of the season. Increased effiency through vermiculture A worm farm would provide food to the fish as well as afford other opportunities for Greens- grow such as the production of soil. Alternate Energy Solar panels would provide alternative energy sourcing for the Aquaponics system. As a non-profit, Greensgrow could gave solar panels donated which would offset the cost of the system electronics. farmphilly an urban agriculture project
  • 10. System Scale Aquaponics can be done a number of different scales. A medium sized system would be most approriate for Greensgrow. Home System Full Scale Farm farmphilly an urban agriculture project

  • 12. Education Educational content is integrated into the Aquaponics system. The design highlights how the symbiotic cycle, and each of it’s components work. farmphilly an urban agriculture project
  • 13. Grow Bed A remote grow bed allows the plants to grow in nutrient rich water, while being kept sepreratly from from the fish that may otherwise damage the roots. farmphilly an urban agriculture project
  • 14. Fish Tank A habitat where fish can thrive and grow to maturity. farmphilly an urban agriculture project
  • 15. Nutrient Sources Traditional fish pellets are fairly inexpensive, but worm farms and duck weed are nearly free alternatives to purchasing farmphilly commercial fish food. an urban agriculture project
  • 16. Solar Power Photovoltaics could directly power electronics associated with the Aquaponics system, or be wired into the grid. farmphilly an urban agriculture project
  • 17. Water Reservoir The addition of a reservoir increases the volume of the system, making it more consistent. It may also help if the pump goes out. farmphilly an urban agriculture project
  • 18. Cost and Benefits of a 100 gallon system 25 lbs. of Talapia @ $10 /lb. $250 End of Season Gross Sales 40 Lettuce Plants (@ full term spacing) 80-120 Haverested Plants $10 /gal. Intial System Cost $1000 Build Cost of 100 Gallon System farmphilly an urban agriculture project
