If my aquaponics has been up and running for a while, would the nutrients in my aquaponics   be good  to grow duckweed without adding anything else, if not what  else should I do, just make sure, that the ph is at 5.5 to 6.5 please help .Thanks for any help that is given( MICHAEL from Tampa Florida)

be careful when adding duckweed to AP systems it can take over the entire surface very fast and become a plague. In the aquarium trade we called it aquarium herpes. Its a great fish food but id be careful if i was adding it to a system i grow some at home in rubber mades to put on my salads and sandwiches.

Sure duckweed is the highest protein per gram of any plant on earth. Its also one of the fastest growing. Its great animal feed and not bad to add to your food for extra protein. It also has vitamins B and C. Its a great little extra vitamin source that is ridiculously easy to grow.

In my experience unless you quarantine the duckweed in the FT the fish will devour it. I had an IBC covered with duckweed and a batch of fingerlings took care of it in 4 days.
