Although all green walls accomplish the same goal of adding plant life to vertical spaces, there are different ways to approach this and the specific limitations and needs of a space will ultimately dictate the best choice.
There are three different types of green wall systems.
Tray systems are the simplest green walls to set up and maintain. Using a grid of 4” slots, replacing plants is literally as easy as popping in a plant that’s still in its grow pot. The plants never actually leave the container they come in from the nursery. Tray systems are irrigated once every week to 10 days, and the pots sit in small amounts of water within the trays until the moisture can be fully absorbed.
Eventually plants in 4” containers will become root bound, and there will need to be periodic replacements of them. While still able to become very lush, the grid system doesn’t provide quite as much design flexibility as the hydroponic wall. However locations looking for a precise design that is easy to maintain, this is often the best option.
Using little to no soil for the root mass, these systems are the lightest weight load of the three. The roots grow behind a wall of capillary fabric and the nutrients are delivered through a solution mixed in with the water supply. This is the best choice for a long term installations.
The plants are able to grow uninhibited, which means the largest and lushest display, and the biggest variation in texture. Under the right lighting conditions this method is able to grow the most diverse array of plants.
While the upfront cost is slightly higher, the long term maintenance cost is reduced because plants are able to fully establish themselves over time with larger, healthier root systems.
The least expensive of the three systems, pockets can work well for the right application. The pockets are large and filled with dirt, causing the largest structural load on the wall of all the systems. Because of the size of the pockets, it’s very difficult to cover the felt with plants, and it requires the most pruning to get it looking right. Even on an expertly planted wall, black felt will be visible.
Felt allows for the easy passage of air and water, and these systems can dry out quickly. They work best in outdoor settings where humidity and rain fall can help maintain the right environmental conditions. When used inside irrigation systems are imperative for long-term health. Because larger cascading plants are often part of the design, maintenance can be time consuming.
