I just discovered a gardening idea - Window Gardens. [Used to be open source but has gone commercial, shame too.] The idea is to reuse otherwise tossed plastic water bottles as the plant pots for a miniature hydroponic garden that hangs in a window. Small and looks to be green, easy and enjoyable. Does anyone have experience with them? The attached picture is one made by the creator, Britta Riley. I am searching for bottles to use and will be posting pictures soon of one I have created.

The idea is to use an inexpensive aquarium air pump to lift growing nutrient to the top of a column of pots. The pots have inert growing medium such as growstones, expanded shale, or hydroton in them and are open on the bottom. The nutrient solution drains down, wetting the stones and feed the plant roots. The unused nutrient passes down the column and is returned to a reservoir to be pumped to the top again.

The systems can grow leafy greens, herbs, flowers, and if you make the bottles big enough, even tomatoes and cucumbers.

I will build one, then post a drawing and instructions on how I do it. You can also find videos on YouTube by searching for "Window Gardens" or for Britta Riley by name. If you want to search the web, go to The is now a commercial site where they are selling systems made using the technology.
