Treehugger has a nice piece detailing an innovative and cost-effective way to maximize growing space: build a vertical bottle garden. All you need is a pile of plastic PET bottles, a roll of twine, cutting implements, and some time.
If you were so inclined, you could modify the design to include a drip irrigation system using rubber tubes or some other kind of pipe. This way you would be maximizing both the use of space and the use of water.
Amazing, right? Another fine example of how great solutions to pressing problems are already here, it’s more a matter a spreading the know-how.
I find these stories of low-cost innovation so inspiring. And lucky for me, more uplifting tales of human ingenuity will continue to arrive faster than ever before.
What a great time to be alive!
