for 20 years i captured, held, and shipped live marine specimens. and for almost 20 now i have grown pot hydroponically so i've got a couple of questions for you.
at some point the combined nitrogen inputs from the fish waste will become toxic to the fish and the water must be changed.
regarding cannabis specifically, isn't this level of toxicty to the fish below the level needed for plant growth?...
...if so are you concentrating the solution in a separate tank before circulating to the plants?
also, how did you plug up the pipe ends?
No, growing aquaponicly requires much less NO3, while conventional hydroponics is much more, and is below the level of that which would keep a fish from being health.
Nitrate (NO3) is not nearly as toxic as Ammonia (NH4) or Nitrite (NO2), and is used by plants, to help them grow.
As you may know, Nitrogen is needed far higher in cannabis's Veg cycle, and less in Flower.
Typically, cannabis requires 20-30ppm of NO3 to grow in Aquaponics, while fresh water fish may live in conditions of that at upwards in the hundreds of ppm.
Hope this helps, cheers
thank you! in a typical aquarium the ammonium and nitrite are converted to nitrate by bacteria rendering them much less toxic to fish. so you are using the plants to remove a greater portion of the ammonia and nitrite before it can be turned into nitrate?
how do you balance fish bio-mass and plant bio-mass?
I can't view the videos.
