TUCSON - If you're interested in growing your own food, and learning how to conserve water, check out the Aquaponics Association's National Conference.
It starts Friday and goes on until Sunday at the Loews Ventana Canyon Resort, located at 7000 North Resort Drive.
Experts from across the United States will explain how it works.
Dr. Gene Giacomelli, Director of the Controlled Environment Agriculture Center at the University of Arizona, gave us a tour of a greenhouse where tilapia fish and lettuce plants are grown.
The fish are in several tanks. It takes about 7 months for the fish to grow to normal size.
Dr. Giacomelli says the water from the fish tanks goes to feed the lettuce. Once the lettuce grows, that water is recycled back in a re-circulating system.
Aquaponics integrates two growing systems: aquaculture or fish farming, and hydroponics, growing plants without the need of soil into one symbiotic system.
Dr. Giacomelli says the technique conserves water because the water is re-circulated.
He says it's better for the environment too because no chemicals or pesticides are used.
