Aquaponics and its benefits
Hydroponics is a method of growing plants with a medium other than soil; it can be peat, sand, vermiculite etc. Here nutrient solution is used to water plants.”Hydro” meaning water and “ponos” meaning labor. Vertical Growth, No soil required It notably cut transportation
“
Aquaponics is a system that combines aquaculture with hydroponics. It is a symbiotic relationship where aquatic animals provide food for the plants and plants in turn perform cleaning of the water. It is a closed loop system that means it is a self-sustaining system where waste of one element is used as a resource of another element of the system

costs to the food retailer
of procurement
Fish are grown in a tank and produce waste
costs in the US
10
Times less land than farming
CUT TRANSPORTATION COSTS Water is circulated into the fish tank
MITIGATE SUPPLY CHAIN
Rainwater capture, water reuse and low- soil needs
Waste goes into a filteration system in which bacteria convert waste into nutrients for plants
RISKS FROM CLIMATE CHANGE Diversifying the food chain hedges against risks from an unpredictable climate future.
25
TIMES
Could be able to capture and reuse more than 810,000 gallons of water
less water than traditional farming methods
The nutrients and the water are pumped to the roots of the plants in the grow tray
ADVANCED HYDROPONICS Cable- culture hydroponics can produce 10 times the yield of traditional outdoor farming
Fater growth of plants
Lightweight plastic envelope Roots Suspended Suspension Cable in water
IMPROVE MARKETABILITY
Growing fresh, organic products locally, grocers can respomd to shifting customer demand
The plant roots help filter the water
No chemical Fertilizers
Intensive planting yields 150 - 200% more per sq ft compared to land farming
Increasingly grocers are looking to local growers to satisfy demand
No runoff into surrounding ecosystem Significantly less FOOD MILES

SAVES ENERGY Rooftop farms insulate the building from sunlight People who integrate and construct their own rooftop farms on refrigerated warehouse space can reuse waste heat from building refrigeration in the greenhouses
Water drains to the middle
Nutrient - rich water enters a reservoir
3
2
Water flows in at both ends to feed the roots
4
Water is collected and recycled
Can be grown anywhere, rooftops, paved lots, indoors and it is portable
Reduces risk of Pest infestation
5- 10 % of the amount of water than traditional agriculture
Organic produce and access to fresh Fish
