Blue Green Box Turns A Fishtank Into A Hydroponic Garden

July 31st, 2013 by  

The Blue Green Box uses the natural waste produced by a fishtank to fertilize plants in its specialized, hydroponic “grow box”. If you have a 10 gallon aquarium, you already have the pumps, filters, etc. to make it work – now all you need to do is get those fish to work for you! You can check it out in this article from Cleantechnica’s sister site, Insteading, below, and head on over to the project’s Kickstarter page to pick one up for yourself.

Urban farming, living off the grid, surviving a zombie apocalypse, spaceflight, and Formula 1 racing. Those seemingly unrelated activities do, in fact, have something in common: the people who are successful at them understand that 1 object can serve…

    I agree with Marion Meads post, but I still think it is cool…

    It is a nice dream but quite impractical. In order for plants to grow well and produce well, you will need plenty of sunlight. If you place your aquarium in the sunlight, you will have plenty of algae in the water. Your algae eating fish won’t be able to keep up with it. That is why we keep aquariums indoors, away from direct sunlight. And this is bad for most of the plants such as tomatoes and peppers. Notice how pale the plants are? The only plants you would be able to use are shade loving plants, and many of them would be herbs.

    But if there’s a will there’s a way. You can put efficient lamps to shine on those plants so that you can produce decent crops. But then again, after factoring all the electric bills by running those lamps, your tomato would cost about $50/lb if ever you get 1 lb.

      Cover the back and sides of the aquarium. That will block sunlight to the tank. The grow box will shade the surface.

      Put it in a sunny window. Rotate your plants about a quarter turn every few days to keep them from leaning too far into the window.

      I built a large one once and used mirrors on the sides and back which made the area look a lot larger.

      That said, this thing is overkill. Just use some wicks that will carry water from the tank to the growing medium. I did a wicking hydroponic system once and seem to remember using strips of cloth for the wicks. Perhaps is was a loosely twisted cord.
