I had a Hydroponic system but still was not satisfied with the output verses input. the natural evolution of the system was to add fish to feed the plants. as long as you don't go crazy with the fish food the system will stay balanced and the output was about 6 times as much.
all I have at the moment is a video of the controlling system but will make a video of the system in action soon when i get a chance.
what i need to do is make a schematic of the system as a whole but what i have posted so far will get a person there.
I wanted to have the system control the PH level or at least monitor it and also the temperature of the air and water but that would add a complexity way beyond my understanding of coding so i decided to add those features separately so the newbies like me can build it easily.
