Hi all,
I'm a young entrepreneur from Chicago and have been concerned about our food system for some time.
Out of college, I started an indoor farming company to research and develop next-gen ag. systems.
I designed some of the largest indoor aquaponics systems around and am now trying to launch a new side venture:

Basically, I set out to design an indoor aquaponic garden that can be built and operated with parts available at many big-box retailers nationwide.
And I've done it.

Now I want to share my DIY Plans with anyone who is interested in growing their own lettuce year round.
Terrestrial plant Groundcover Plant Grass Shrub

The system is call the Lettuce AquaGarden 3624 and it can produce up to 450+ heads of better-than-organic lettuce per year!
That's enough to feed two people, day in and day out.

Again, every single part can be purchased from local big-box stores, so you can start farming at any time.

Imagine knowing that your food supplies will never run out; that you can always have the freshest greens imaginable- even in the dead of winter!
It's really simple because I've spent years developing the procedures and designs that allow for easy assembly, operation, and scaling.

If you are interested in the ultimate piece of prepper equipment, check my site out at New Document - Created By AjaXplorer for more information.

Happy Prepping,
The AquaGardener

Here is a pretty good book imo, it is old, probably out of print, but there are a lot of intersting books on indoor hydroponics growth.

100x150 feet is generally sufficient to supply a
family of five persons, not considering the winter
supply of potatoes

Also in a real SHTF, major problem people may not have access to animals so knowing how to treat your urine and feces to grow food may help...
These are useful documents from the world health organization:

If you know your stuff, communal lantrenes can be turn into a source of methane for cooking and heating.

Urine should be kept seperate from feces, it turns into ammonia more or less which is a powerful fertalizer.

Urine is VERY useful, take for instance

As a fuel

Ammoniacal Gas Engine Streetcar in New Orleans drawn by Alfred Waud in 1871.

The X-15 aircraft used ammonia as one component fuel of its rocket engine
Ammonia was used during World War II to power buses in Belgium, and in engine and solar energy applications prior to 1900. Liquid ammonia also fuelled the Reaction Motors XLR99 rocket engine, that powered the X-15 hypersonic research aircraft. Although not as powerful as other fuels, it left no soot in the reusable rocket engine and its density approximately matches the density of the oxidizer, liquid oxygen, which simplified the aircraft's design.
Ammonia has been proposed as a practical alternative to fossil fuel for internal combustion engines.[52] The calorific value of ammonia is 22.5 MJ/kg (9690 BTU/lb), which is about half that of diesel. In a normal engine, in which the water vapour is not condensed, the calorific value of ammonia will be about 21% less than this figure. It can be used in existing engines with only minor modifications to carburettors/injectors.
To meet these demands, significant capital would be required to increase present production levels. Although the second most produced chemical, the scale of ammonia production is a small fraction of world petroleum usage. It could be manufactured from renewable energy sources, as well as coal or nuclear power. It is, however, significantly less efficient than batteries.[citation needed] The 60 MW Rjukan dam in Telemark, Norway produced ammonia via electrolysis of water for many years from 1913 producing fertilizer for much of Europe. If produced from coal, the CO2 can be readily sequestered [52][53] (the combustion products are nitrogen and water). In 1981 a Canadian company converted a 1981 Chevrolet Impala to operate using ammonia as fuel.[54][55]
Ammonia engines or ammonia motors, using ammonia as a working fluid, have been proposed and occasionally used.[56] The principle is similar to that used in a fireless locomotive, but with ammonia as the working fluid, instead of steam or compressed air. Ammonia engines were used experimentally in the 19th century by Goldsworthy Gurney in the UK and in streetcars in New Orleans.
