I couldn't get permission to copy a photo of this, but I'll describe it and provide a link.
"The flying soda bottle flotilla"
"wall of bottles"
"100 bottles of pop on the wall"
"I did it sideways"
Someone made hanging planters from 4 or 5 bottles (2-liter soda bottles) hung
sideways on two wires running [u]through the bottles, near the cap and near the
Each bottle has a rectangle cut out of its uppermost side for the plant. I couldn't tell if they drilled drainage hole or how they handled dripping.
Then they made a "wall" with 6 sets of those hanging planters, around 3 dozen bottles.
