That is not how aquaponics and vertical farming work. They use solulable nutrients which are either gained through a nutrient cycle (the water flows down to a pool which has fish in it), or via mining of otherwise hard to get nutrients. Soil is not used. While the source of all these nutrients is a problem, it is comparible to the huge quantities of petrolium based fertilizers that we use today. It is bad, but what we have now is bad too...

... so you are proposing a bad idea that seems pretty wrong from multiple aspects. generally hydroponics is a sht cheap substitute for real growing for those who cannot afford quality vegetables (sadly, I sometimes fall down that hole too and then regret this decision while eating this tasteless cr*p full of unhealthy chemistry).

no, thank you for many reasons
