Here’s a very interesting youtube channel called Adi Irawan ; you might have guessed they are indonesian!
They explain quite well how they build and run home made aquaponics systems.
Here’s an introduction video in english, while most of the others are in indonesian… which you sadely might not speak like me 😉
Their latest structure tutorial for rice growing is rather interesting to follow as it is quite efficient and apparently neither hard or costly.
This « spiral » structure for lettuce is nice and efficient, much to like here!
I kind of wonder which fishes species they find adapted to their setup. Apparently they used to be golden fish but in the most recent videos they seem to be using a smaller variety.
