Scott is giving away his aquaponic system! If you are interested in it, please email brian@anacostiaaquaponics.org and we will put you in contact with him to arrange the transfer.

The system includes an IBC fish tank, a full IBC sump tank, a 55-gal
settling filter, 3 half-IBC grow beds and 4 half-barrel grow beds.

Here is the work required to operate the system:

Daily (about 10 min but only during growing season)

Feed fish, general upkeep of plants, check water flow and unclog anything as needed.  Sometimes harvest daily, sometimes less frequently.

Weekly (about 20 minutes)

Discharge solids from settling tank (I discharge to my lawn but could use as fertilizer in garden), check and adjust water chemistry (more on this below), check water flow and unclog anything as needed.

Annually Late Fall (1-4 hr)

Clean out plants.  Shut off part of the system (close a valve). Install cheap pond heater to prevent freezing.  Could plant cold-weather plants but I usually have a few greens already in there (oregano, parsley, beets, some perennial onions) that survive winter OK. In winter, feeding is much less (once per week) and plants don’t grow.

Annually Spring

Plant out beds. This can be putting individual seedlings in a carefully organized way.  Lately, I just throw handfuls of seeds in the beds and whatever grows, grows.  Greens like kale, kholrabi, beets, turnip greens, and herbs (parsley, dill, oregano) grow well without any intervention.  Fruiting plants require a bit more care and careful attention to water chemistry and nutrients. In the past, I’ve grown fruiting plants well, like green beans, eggplants, and tomatoes.  In the photos, you can see some greens going to seed (beets, dill, parsley).  I just let them go, collect the seeds and throw the seeds back into the beds.

Sustainable DC Agriculture Progress Report

Washington DC just released its Sustainable DC Progress Report.

Check out the Report here: https://sustainable.dc.gov/progress

The main agricultural goal is to put 20 additional acres under cultivation for growing food by 2032.

Is total acreage the appropriate goal? How much food is expected to be grown on these 20 acres?

And does anyone have data on the current agricultural production in the district? What % of our own food are we growing!?!

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!

DC Teachers’ Night at Botanic Gardens

Anacostia Aquaponics will have a table at DC Teachers Night this Thursday, Jan 30 at the U.S. Botanic Gardens.

This event is an opportunity for teachers to meet with environmental educators and bring more environmental education into DC schools.

Aquaponics is a powerful tool for STEM education and teaching environmental concepts. Aquaponic lessons fit perfectly with Next Generation Science Standards. Students learn and study the interaction of fish, plants, and bacteria in the living aquaponic ecosystem!

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 and flower startup industries.  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.
