My ultimate system is definitely aquaponics and all its various offshoots. Growing fish and vegetables all in one system? That's just cheating at this point surely ๐๐คฃ๐๐๐. I can blame my foray into aquaponics to landing me in this world of sustainability and permaculture. The moment I saw it, it just made sense.
A system where biological process defines every element of the growing processes? Whaaaaat?!! ๐คฏ๐คฏ๐คฏ๐คฏ. You allow the biology to naturally grow, you add the fish, the fish waste feeds the microbes, the microbes convert the fish waste into food for the plants.... The plants filter the water and reoxygenate the water, that same water is used to grow the plants and you pump the water back into the fish tank....
Understanding that cycle ,led me squarely into permaculture. It's the same process. Understanding the biology, the soil, what we,animals and plants need .... Then working towards allowing nature to do its thing...
The fish water has had massive part to play in the successes we have had to regeneration of our land. And it doesn't have to cost an absolute fortune to build your own...
Have you heard about aquaponics?
