Doesn’t outcome of the discussion depends on defining “hydroponics” and “organics” first?
I mean I’ve been many times using term hydroponics for indication of way to create ideal root environment (air/water ratio) without any need for soil. So I take hydroponics as kind of equivalent to “soil less”. If you don’t put plants into nutrient rich soil, you just have to bring nutrients through the solution.
IMHO In this sense it is perfectly OK to kind of have mix of hydroponics and organics in one system and great example for that is aquaponics (bioponics).
But I know there are many other ways to view and label the same thing.
Maybe it is just matter of labels that we give to thinks to “separate” and “divide” them into categories. Categories that are not so isolated that we might think at first.
There is nice example here on OG - Dumme’s Aquaponics Adventure - how would you describe the system? There are many labels fitting…
