In my post I have shown my aquaponics system and what we did with the fish poop.

At the end our backyard garden was way too small and we gave the fish/crayfish poop away to our neighbors and they had the same results.
Their backyard ended after one year as a jungle same as ours did.
Here some pictures of our garden after one year.
bananas are not supposed to be that high, neither should dwarf bananas have so many flowers but also the harvests of veggies (here spring onions in equal size and still there was enough food for our Dutchman's pipe vine to shade the porch and lure wedding couples at our fence for a shot under an abundance of flowers. ;-)
