The problem is that once you start living off aeroculture or aquaculture food, your population will develop significant deficiencies. You need mineral soil for … minerals, amongst other things. Magnesium, calcium, there’s a reason they’re called alkaline earth metals. And once you think of adding something to the water, there will probably be something else you haven’t thought of.

Sorry, but that’s just not true. Hydro- and aeroponics systems use tailored mineral solutions to start out with. What deficiencies are you speaking of?

Some organic farming enthusiasts and lobbyists tend to treat ‘ponics as a competitor and a few occasionally go a bit overboard. Factoids get into the wild that have no relationship with what actually goes on in a ‘ponics farm.

… and yeah, a hobby when I was younger 🙂
