Bob Pellegrini and Peter Kastan from Jungle Walls in Miami emailed in photos of their Patrick Blanc style vertical garden they created. The call it the “River Wall ” because it is located on the South side of the Miami River.
Inspiration - The 12′ X12′ Hydroponic Wall follows the concepts set down by Patrick Blanc .
Lighting - The lighting consists of 4-400 Watt overhead lights .
Plants – 500 plus plants are Sub Tropical , bought at local South Florida nurseries, and are from around the world.
The basic construction consists of;
- Frame - 3 Aluminium frames , 4′ X 12′ . Made if 1″ X 2″ box extruded Aluminium were joined to form a 12′ by 12′ frame . This frame was hung several inches from the brick wall
- PVC - This frame is covered by 3/8 ” thick sheets of 4′ X 8′ expanded PVC
- Felt – Then the surface is covered by 2 layers of a thick felt-like material. high quality , non-rotting poly propylene , produced by Hydrotech in Chicago . It is 3/16″ thick , ( 200 mm ) , with a water retention capacity of 0.13 gallons/sq.ft , ( 5.31/ sq.m. ). There is no soil used
- Irrigation – Nutrient-rich water is delivered to the top of the wall and ” wicks-down ” through the fabric to a gutter , which deliverers it back to the reservoir. The gutter at the bottom of the River Wall , is designed to return the nutrient-rich water to an aquarium located in a separate room.
- Planting - Slots cut in the outer felt layer are used as pockets for receiving the plant roots
