Rear Irrigation Feed
Advantages
Wall-to-wall coverage
May eliminate need for a side treatment (facing material)
Drawbacks
More expensive
Takes more time to install
Deeper profile
Recommendations
May require side treatment depending on site conditions and desired aesthetic. On new construction, consider recessed walls to reduce the living wall profile. For the plants to be flush with the adjacent wall surface, recess green wall area by 11 inches with Standard-sized planters and 13 inches for Large-sized planters. To conceal the thicker furring strips only, recess green wall area 5 inches.
