Soil vs Hydroponics: Which is Better for Living Walls?

Soil vs Hydroponics: Which is better for living walls?

When considering installing vertical living walls, it’s important to understand the differences between soil-based and hydroponic green wall systems. Both systems can create excellent visual results, improve air quality, and boost well-being, but they operate in very different ways. Let’s discover the key things you need to know about both systems so that you can understand the advantages and drawbacks of both options.

Soil-based Living Walls

Soil-based living walls use traditional growing methods. The plants are rooted in a growing medium, which is usually soil or compost. This provides a natural structure for their roots to establish. These systems recreate the conditions found in traditional gardens, allowing for the growth of a wide range of plant species. One of the most commonly shared benefits of soil-based living walls by owners of this type of green wall is the simplicity of the system. Soil naturally provides a buffer for water and nutrients, making this type of system ideal for beginner gardeners, business owners, or those less experienced with caring for vertical living walls.

A soil-based living wall installation also comes with challenges, and you really need to carefully think about whether you have the time and energy to support this installation. Soil can be heavy, making the wall structure more challenging and expensive to install. After you have this installation in place for a few months, soil can become compacted, which may disrupt root development and limit plant growth. Soil-based systems can also be more prone to pests and diseases, requiring careful monitoring and management. You’ll want to make sure you fully understand the maintenance needs of this type of system before it’s installed to avoid any issues or damage to your plants.

Hydroponics Living Wall

Hydroponic green walls do not rely on soil. Instead, they use a nutrient-rich water solution to provide plants with everything they need to grow and thrive. Plants in this type of system are usually grown in an inert medium, such as rock wool, which supports the roots but does not provide any nutrients. One of the top benefits of hydroponic living walls is their lightweight structure. Without soil, these systems can be installed on a wider range of surfaces, including indoor environments where heavy structures are a concern. They also offer more control over nutrient delivery, which can encourage faster plant growth and healthier plants.

Hydroponic systems can be particularly beneficial in commercial settings or areas with high foot traffic, where regular maintenance may be easier to schedule. The precise delivery of water and nutrients in these systems means plants can grow quickly and evenly, resulting in a very attractive display for your workplace or home. Hydroponic green walls are more technically demanding. They require careful monitoring of the pH levels, nutrient concentrations, and water quality to ensure plants remain healthy. These systems also tend to need more frequent maintenance and the installation of pumps and irrigation equipment, which can add to the overall cost.

Which is the Best Option for Your Living Wall?

The answer to this question largely depends on your specific goals and the location of your intended living wall installation. If you’re adding a living wall to a residential setting or prefer a low-maintenance option, a soil-based living wall might be the best choice. These walls can support a wide range of plants and are easier to maintain if you aren’t as familiar with this type of installation. If you are aiming for a modern installation to change the aesthetic of your space and have access to the required equipment, a hydroponic green wall could be ideal for your workplace. These systems provide excellent control over growing conditions, resulting in healthy plants that grow quickly and consistently.

Whether you choose a soil-based or hydroponic system, installing a green wall can have many benefits for your workplace and employees.
