Step 1: What you will need
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.)
hole saw (for yogurt cup)
hole saw (for PVC pipe)
Step 2: PVC fill tube
Step 3: Drilling the inner bucket
Again using a drill-mounted hole saw or a reciprocating saw, cut a hole large enough for the PVC pipe. This hole is located near the side of the bucket.
Drill a few 1/4" holes in the bottom to let excess rainwater drain away from the roots.
