I recently joined the windowfarms community and am very excited to have discovered this idea.  I will be starting on my first window farm this weekend and have started gathering the materials for it.  I will post a parts list and cost when my first version is up and running.  As an engineer in the solar industry I love using the free Google Sketchup 3d modeling tool for many of my projects.  Below are several images and a youtube video of some of the concepts I’ve drawn up to try and come up with an aesthetic design to increase the wife acceptance coefficient of my project.  I like the idea of using cut wine bottles but it will take me quite a while to gather enough bottles.  I started with the idea of using an aluminum strip as a central support but decided on something that would hide the tubing better.  I’ve narrowed it down to using 4″ glazed clay pots to hold the net cups, supported by 4″ grates made from sytrene plastic.  I will eventually switch to all copper tubing but for now will be using black drip line tubing I have lying around at home.  The central support structure is 3/4″ galvanized steel electrical EMT conduit to aesthetically hide the tubing.
