Problems with container gardening include not enough root space and the difficulty of effective watering.  Top watering is slow and it is hard to get enough water into the container to satisfy the plant's needs.  The double bucket approach to container gardening provides more soil for roots than many containers provide and there is enough water available so that even tomatoes usually don't dry out during the day.   The PVC pipe delivers the water to the bottom of the container where the roots can more easily get at it.   

Step 1: What you will need

Picture of What you will need
Materials:     2- 5 gallon, nesting plastic buckets
                       2' x 1-1/2" PVC pipe  (diameter is up to you but a larger diameter is easier to fill)
                       1- 3/4" x 6 screw ( I use hex head)
                       1- yogurt cup (8 oz.)

Tools:            drill
                        bits
                        saw
                        hole saw (for yogurt cup)
                        hole saw (for PVC pipe)

Due to the height of the yogurt cup, I cut off the entire bottom using a hacksaw. You could just put three or four 1/4" holes in the bottom using a knife.
