Here is my new system to build a vertical garden – it is my next project. Please excuse the messy planting – this is concept stage only.
It is normally positioned the otherway up and provides air into homes (see below)
The vent does not offer a lot of growing room therefore a shallow rooting plant is required.
Dry tolerant plants would be best given the likelihood of this vent to loose water very quickly. I am thinking succulents – Mother of Peral is the main plant I have used in this demonstration and am thinking it might perform well.
I will line this hood with a geotextile to ensure soil does not escape out the metal mesh.
Notice how the back of the vent is inverted (image below) ? This is good as the back will not sit flush against a wall or fence thereby protecting the vertical surface from water damage. Also the frame allows the vent to be hung very easily over wire as shown above.
I can see heaps of potential – stay tuned
