VSU Water Quality Checkups

Before COVID struck, researchers from Virginia State University took water samples and bacterial cultures from aquaponic and hydroponic systems in the Virginia region, including at IDEA Public Charter School. The tests will check for water quality parameters (pH, hardness, total ammonia) and for food safety considerations.

The results will be used to promote sustainable aquaponic production in Virginia.

Water quality and food safety tests are important for the IDEA PCS aquaponic and hydroponic systems because the produce is served in the school salad bar.

These tests also introduce students to the food safety profession, which will be increasingly important as the population grows and the climate changes.

Seeking new school partners

Anacostia Aquaponics is seeking to expand aquaponics and urban agriculture education in Washington, DC.

Across the country, aquaponics is proving to be an ultra-engaging teaching tool for STEM Education concepts and Career and Technical Education.

Let’s foster a new generation of urban growers in DC! Contact us: brian@anacostiaaquaponics.org

Aquaponics in STEM Education Info Packet

We had a great time at DC Teachers Night last week at the US Botanic Garden (USBG).

Check out our STEM Aquaponics Info Packet.

Also check out a great new free resource: Greenhouse Manual; An Introductory Guide for Educators from USBG, City Blossoms, and the National Center for Appropriate Technology.

Did you know over 90% of our seafood is imported and our average lettuce travels 1,500 miles!? Let’s boost urban agriculture!!!

Rooting DC Feb 29

Mark your calendars for Rooting DC, DC’s free annual Urban Ag Forum.

This year’s event will be at Ron Brown Prep in Northeast on February 29, from 9:45am to 4:15pm.

Anacostia Aquaponics will be co-hosting a table with IDEA Public Charter School.

Anacostia Aquaponics Director Brian Filipowich will give a presentation Small-scale Aquaponics for Urban Food Production at 9:45am.

Above is a pic from Rooting DC two years ago when we had some fish in the vendor showroom!

Aquaponic Flower Experimentation in MD

By Tom Precht

Our flower farm, Grateful Gardeners, is a 1 acre plot in Boyds, MD, providing fresh, organic cut flowers to the local market.  We are big believers in green practices like aquaponics.
While vegetables are grown readily and with great success, flowers have not been fully attempted and investigated (with a few notable exceptions).  We decided to implement a pilot study of whether or not we could grow a few different forms of flowers; Zinnias (seed), Ranunculus (corm), Dahlia (tuber), and Dahlia (cutting).
We started with a basic DIY Barrelponics system, built from the free online plans out of 3 x 55 gallon food grade plastic barrels.  We had very little money to invest in this and so we decided to use pea gravel as our grow media (a decision we would regret later as all the manuals show out there) because it was less expensive than Hydroton.
We started with Tilapia fingerlings once the system was cycled. Initial results were promising, we saw rapid growth of Ranunculus corms, Dahlia cuttings, and Zinnia seeds in the system.  Tubers did not seem to take off, but the quality of the tubers may have been an issue.  The images of the growth show the speed with which they developed.  The pea gravel started to create some pH issues and because we were not in a fully insulated space, and this was November and December, we couldn’t regulate water temperature adequately.
We eventually lost all the fish and had to shut the system down early.  We are only now restarting the system in a newly built greenhouse which we hope to be able to heat through the winter months to try these same experiments again.

Aquaponic Lettuce at IDEA PCS Salad Bar!

The IDEA Public Charter School Cafeteria recently served lettuce grown by students in aquaponic and hydroponic systems.

Students in Urban Ag Club germinate, transplant, and harvest lettuce. They also feed the fish. Then they see the fruits – nay, vegetables – of their labor in the salad bar!

Students learn the science of growing, and also build skills in urban agriculture, food safety, horticulture, and water management.

Students learn that we must follow Good Agricultural Practices if our food will be served in the school or sold commercially.

The next step is to scale up and see how much we can grow!

Hosting Chinese Government Delegation

Last month, Anacostia Aquaponics hosted a delegation of 20 researchers from the Chinese Government for two days of lectures on aquaponics. We also arranged a tour of Bella Vita Farm in Brookeville, MD.

The delegation is travelling the U.S. for three weeks to study modern agriculture technology. They are visiting Washington, DC, New York, and Chicago.

Anacostia Aquaponics Director Brian Filipowich stated “I enjoyed spending time with the researchers and discussing different agricultural trends in our two countries. We have a lot to learn from eachother.”

Three More Small-Scale Aquaponics Graduates

Thanks to Sean, Gerald, and Damon for participating in Anacostia Aquaponics’ Small-Scale Aquaponics Training Course. That’s now 20 graduates — 19 from the DC metro area and one from Nigeria 🙂

The Course is designed to provide participants the skills and knowledge necessary to understand and meaningfully participate in the design, construction, and operation of a small-scale aquaponic system (10- to 1,000-gallons).

Stay tuned for another opportunity to learn small-scale aquaponics in Winter 2020!

Commercial Aquaponics in Gaithersburg, Maryland

Bella Vita Farms LLC in Gaithersburg, MD opened a new greenhouse with a state-of-the-art aquaponic system about three months ago.

The farm has had no problem selling their produce at great prices because local chefs recognize the quality. In fact, they cannot keep up with demand and the farm already plans to expand the aquaponic system.

Bella Vita staff noted that not only does aquaponics provide top-notch produce, but it is also much friendlier for the environment because it uses much  less water, and no synthetic pesticides or fertilizers that pollute our waterways.

The Farm started with koi, but just recently transitioned to tilapia, which they also plan to sell to local restaurants.
