I love the idea of hydro/aquaponics and built a system as a student more than a decade ago. It’s a fun project.

But as a form of agriculture it’s a spectacularly bad idea at home.

This setup is about 1 square meter of NYC space, that’s about $18k. Meanwhile agricultural land goes for about $2/m2, or 9000x less. Then you spend $700 in parts to set up the 1 square meter, even if you put the system on cheap rural Kentucky land. Then you pay $170 a year to power the system for again, 1 square meter.

Meanwhile the 1 square meter produces like less than $100 in annual produce.

Green house farms like in the Netherlands have perfected this growing method and it’s quite effective. Home food production is a joke by comparison just like home anything production of a commodity product.

So fun DIY projects but as a serious way to grow food it’s terrible, not economical or sustainable. I tore down my project the same year I built it, taught me a lot but made no sense to continue.

Yep. I initially looked into it as a potential avenue for sustainably producing some of my own food, but the math absolutely did not make sense.

Growing a bunch of potatoes in a barrel would be a lot more bang for your buck with that goal in mind. To really optimize costs and labor, though, as you say, you need a greenhouse and/or a big old field, just like always. There are no small-scale shortcuts. Not yet, anyway.

It makes me a bit sad that even with modern tech we haven't really made it much easier for people to produce their own food. But it's a reminder that our food production requires large scale collaboration and cooperation. Maybe that's a good thing.

By this logic, doing anything yourself is inefficient and a waste of time.

However, I think that by reducing it purely to a monetary number, you are not measuring things correctly. Part of the output of doing DIY things is the knowledge, experience, and fun that comes from doing it. If you insist on putting a dollar sign on that, I’m sure it ends up being much more equal.

No one is reading this thinking it’s going to replace industrial farming. It’s just fun
