The logical choice for my indoor gardening is 1: container and 2: hanging. So after doing a few searches on the net I had come across a few options. There were of course the usual hanging planters that are really nothing more than a regular pot with strings tied to a ceiling hook. These really didn't appeal to me due to previous experiences where the water flowed down through the soil and filled the overflow basin at the bottom. Another option is hanging inverted planters which have been around for a very long time. Some in a much older design made from terra cotta in a traditional Mexican style and a newer one made of plastic that had internal foam spacers for dirt/water containment.
This naturally put my mind into make it myself mode. Whenever I get one of my project ideas. I start drawing different options in paint. I wanted it to be a conical-type container for water retention purposes. After drawing a few designs the one I decide on was to use a inverted 2 liter soda bottle with a few modifications to make it better suited for planter use.
