Really cool and easy way to garden vertically and avoid weeds and soil pests.
If you are a small farmer or a home gardener that wants a proven system to grow crops and flowers you will appreciate this one.

4 tiers of painted cola bottles on a 4 x 4 post.

Drip irrigation and a timer make this a real water saving system too. You have to find someone who drinks lots of high fructose corn sugar AND is willing to donate their bottles for recycling.

The other components can be purchased at Home Depot and the parts list and instructions are online to print here for this system. Have fun!
