I absolutely love this gardening idea. Very good gardening ideas for small gardens. I want to do it on my balcony.
The first time I saw it on Youtube. I was really shocked.
Now I find on internet this Filipino garden called JoJo.
Here JOJO with a wide variety of plastic bottles in order to build a strong bottle garden, not only species. Self sufficiency has become a near model of learning for students and residents. Also make him a plastic bottle on a network of people to grow vegetables.
You can set them up on their sides and affix them to walls, or simply lay them down flat. Raised self made flower beds are also a good idea.
These look really interesting.
