You actually have a aquaponic system. Without the fish it would be hydroponic system.
If you want a very self sufficient hydroponic system that doesn't use any electricity then I recommend Growbox 2.0 by Mike Adams from NaturalNews.com.
I also recommend that you subscribe to his weekly newsletter to get inform about the food revolution and herbal medicine from food you can grow.
Correct, i renamed it, thanks! Yeah, i know this product, awesome! But for now we stick for our diy project :)
