Talking about plastic bottles...I bumped into this vertical garden project made out of used plastic bottles in Sao Paulo. It is part of the project called Lar Doce Lar done for Brazilian television in which Studio Rosenbaum designs homes for people living in poor conditions. Through this project they try to improve the living conditions of these families. This urban garden was part of the Rodrigues House project... a house for a mother who raises her 2 daughters on her own and earns around 80 euros per month . These women were already using used cans for planting, so that's where the idea came from.
I just love the idea, and will try to do something similar next summer for my home. The designer even made a tutorial on how to make it on your own...Awesome, if you ask me :)
