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.

Bamboo Privacy Screen/Trellis

I am inspired by Zen garden ideas about importance of boundaries.  So as the first step in remodeling the southern balcony in Japanese style I built a bamboo trellis which doubles as a privacy screen.  I hope it will also help to fight the scorching heat while retaining the light breeze.
So here are the steps I took for this (not so) little DIY project:

Plumbed Draining Tray

Ideal planter for my balcony would have drainage which I could plumb so that the water is routed off the balcony.  Self watering containers could probably be customized for this.  So far I am focusing on creating a drip tray with plumbing routing the water off the balcony.

Common Parts

I use economy-priced of-the-shelf components.

Tray

Elbow 1/2" male thread to 1/2" barb

1/2" tubing

I took the design through a couple of iterations.

Lessons Learned - Planters and Plant Stands

My balconies are made of wood.  And there are neighbors under.  Therefore I do not like the idea of having pots on the balcony floor.  Its makes hard to keep floors clean and neighbors would not appreciate water dripping from their balcony ceiling.
Therefore pots need saucers.  And stands.  So that I can use a leaf blower to clean the balcony in seconds.  Oh! And the saucers should come with drainage for water runoff.  Outside the balcony.  I still have not found yet an ideal combination of planter/saucer/water drain. 
Therefore I am trying to build one!
