Vertical Hydroponic Grow Systems in Downtown DC

We recently worked on planting and harvesting vertical hydroponic systems at the new Fannie Mae office building in downtown, DC.

These systems make the best use of space by stacking hydroponic shelves vertically. All four levels are connecting to one common reservoir, which is directly connected to the DC water system.

The hydroponic system is from the Urban Cultivator. Pictured here is Niraj Ray from Cultivate the City.

Cultivator 1.0 Test Model

This past Summer we experimented with a prototype vertical aquaponic system – The Cultivator 1.0 – on the Cultivate the City rooftop farm by H Street, NE.

Re-used food grade 55-gal barrels cut in half served as containers for the fish tank, grow bed, and sump tank.

The Cultivator 1.0 is intended to make the most of vertical space in our dense urban environment by stacking the containers. The vertical arrangement also makes water-flow more convenient.

Was the Cultivator 1.0 successful? stay tuned to find out!

The Hootie 2.0 at Iona Senior Services in NW DC

We just installed our new aquaponic system, The Hootie 2.0, at Iona Senior Services near American U. in NW DC.

The Hootie 2.0 can accommodate up to 8 medium size (.5lb) goldfish or other ornamentals. The fish waste will support a constant growth of herbs and several heads of leafy greens at a time.

The Hootie 2.0 features:

  • a 29 gallon fish tank;
  • a roll-out plant growbed for easy fishtank access;
  • hidden shelf space for electrical connections, an aerator pump, and supply storage;
  • adjustable height T5 floursecent light fixtures; and
  • an automatic bell-siphon drain in the growbed to increase system oxygenation and circulate water.

Thank You Ashlea Steiner at Iona Senior Services for the opportunity!

And Thank You John Favaloro at Avanti Woodworks for the great craftsmanship and creative problem-solving!

The Hootie 2.0

Working with Neto Construction in Sterling, VA on the next model of our indoor aquaponic system, the Hootie 2.0.

It has a 55-gallon fishtank on wheels for roll-out easy access. (See Hootie 1.0)

Here we see Danny Neto cutting some Ultra-Skrim FGC liner, a great product from Global Plastic Sheeting. It’s handy for aquaponics because  it’s:

1) very puncture/tear resistant;
2) pliable;
3) food grade; and
4) only 13 microns thick, whoa baby!!!

Brewing Vermicompost Tea at the Aquaponics Meetup

Here are Julie, Hala, and Cheryl getting ready to brew some vermicompost tea at our aquaponics meetup last night. Cheryl looks to be digging under a bed of newspaper to find our squiggly friends below.

About 10 or 15 local aquaponics enthusiasts came by to participate last night. We tested the system water for pH, ammonia, and nitrates and discussed the results; we chatted about fish feeding ratios; we brewed vermicompost tea and discussed applications for aquaponic systems; and we added worms to the media bed.

Thanks everybody who came out to visit and share your knowledge. We’ll be posting more practical info about vermicompost tea applications in aquaponics, stay tuned!
