DIY Sub-Irrigated Container

I am very much impressed with this project!  And decided to use this approach for my next container.  No, I did not buy it new, rather "used" which is much much more affordable.  So here it is with 3" corrugated perforated drain pipe - 10' piece cut to fit the 36" container.

From what I can tell the key to success is the soil mix:

The basic idea here is that you're constructing a mix that will effectively wick moisture to a vertical height of at least 14" (peat moss). However, that same mix must be porous so as to provide proper aeration to plant roots (perlite). Also you should have enough drainage for rain water to escape down into the water reservoir.

Community Garden Plot

I've got a 10'x10' plot in a community garden.  For 5 years.  The plot has a water supply and is built on a solid clay soil.  No permanent connection to water supply is allowed.  My plan is to build two 10'x4' raised beds.  Here is my inspiration.
