Green wall is a showstopper

Green walls are best suited for indoor spaces where the temperature is over 15 degrees celsius. It is also possible to build green walls outdoors for short term projects. Outdoors, the plants will stay fresh from a few days up to a week. The green wall can be made to fit any specific shape. Our most typical projects are green walls made of living plants and rectangular in shape. But sometimes there is a need for something totally different because of the space or a specific request.

We always prefer to use living plants if possible. Sometimes the space and users create restrictions for the use of living plants. We aim to use of more than one species of plants in our green walls to for example prevent the spreading of various plant diseases. The use of several species of plants makes the wall more bold and showy and with the choice of plants we can create different atmospheres. The green wall can be playful, dramatic or calming if needed. InnoGreen’s green walls are all planted in our facilities before they are transported to the customer. We also maintain the plants in the green walls on a regular basis. Additionally we can change the plants for blooming seasonal plants to bring variety and a new look.

The maintenance-free moss wall has also become increasingly popular in recent years. Stabilized plants or leaves and other natural elements can be attached to the wall to create more dimension. The base underneath the moss layer can be any shape, so moss walls can be used to create green letters, different logos or, for example, a map of the world. Moss walls and stabilized plants are also a good option when you want to bring greenery to a ceiling or other high spaces, where maintaining the plants would be difficult or dangerous.

The moss is stabilized, which means that living moss has been preserved with glycerin. Stabilized moss retains its beautiful green color for years, it doesn’t require watering or regular maintenance and it’s recyclable and biodegradable. Of course, sometimes people can’t resist touching the soft-looking moss in public spaces, for example, and in that case even stabilized plants might require occasional repair.

The modular structure of our green wall

Our green wall structures are not fixed but are made of several modules. The modules can be stacked, placed side by side or organized on top of a frame in the shape of a e.g. a plane. The green wall is usually mounted on a wall but because of its versatile structure the wall can also be a freely movable element. Just place wheels under the wall and you have a space divider!

Our walls consist of two parts: the plant panel and the basin. The plant panel is attached directly to wall structures. The necessary water and nutrients are fed through the basin. Depending on the circumstances, the basin can be replaced with a tap water connection fitted with a solenoid valve, nutrient doser, timer and pressure regulator.

Plant panels of the Green Wall

The plant panel is modular. One module is 600 mm wide, 165 mm high and 200 mm deep. Each module can house four plants in their own individual SACK planter bags. The modules are made of ABS plastic by Okartek in Kaarina, Finland.

Module aluminium rails

The modules are mounted to aluminium rails so the panel is not in direct contact with the wall material. The fixings and other structures do not need to be protected as the water circulation within the panel is closed. Irrigation pipes run inside the modules and distribute water evenly between them.

Module irrigation system

The irrigation system is always closed. This means that there is no water dripping from the leaves or along the wall.

There are two irrigation systems available:

1. A pump inside the basin pumps water and nutrients to the plants once weekly. The irrigation can be timed to cause minimal disturbance to those staying or working near the wall. The basin has a biofilter, which recycles and oxidises water to prevent unwanted bacteria.

Water loss is minimised by recycling excess water back into the basin. Should the pump for some reason remain on, it does not consume any extra water.

2. Green wall is equipped with a tap water connection. The green wall is fed lukewarm water via a timer-controlled solenoid valve. The pipe installation is fitted with a doser that regulates the nutrient content of the water. Any excess water is directed to a collector positioned at the bottom of the plant panel and on to a drain.

A green wall for any space

Our selection of green walls is growing with a new model in spring 2023. The new green wall is built from the same modules than our original green walls, but it is stripped from any technology such as water pumps. The plants are watered manually every 2-3 weeks at the same times as the plants are maintained. The same selection of plants is available for the new green wall model as the original ones, so you don’t have to compromise on your dreams. The new green walls can also be built both indoors and outdoors. 

The lighter structure of the new green wall also means a lower cost, so the new model works for both smaller spaces and smaller budgets. The simpler structure creates new possibilities for the green walls – for example, they can be hung on a wall like a painting, since without a water basin they are light enough and there are no pipes in the way. The new green wall helps bring plants into even more challenging spaces and lets us be even more creative.

Green wall plants

In hydroponic gardening systems, the plants grow in expanded clay aggregate completely without soil. This intensifies the plants’ air quality improving properties and eliminates any soil-related health problems, such as the distribution of mould spores. In semi-hydroponic systems, the plants and their root balls are inserted in an inorganic growth medium.

The plants are selected according to the customer’s wishes and the atmosphere of the space. The final selection is made on the basis of the plant supplier’s proposal.

The lighting is realised with a state-of-the-art LED system characterised by a very long service life. Bulb spectrum is similar to the appearance of daylight, which not only allows the plants to receive just the right kind of light, but also enhances their visual appearance.

Green wall power consumption

65 W pump: 1 h/month (15 min./week)0.065 kWh/month
5.5 W biofilter: 24/73.96 kWh/month
2 × 50 W LED: 12 h/day54.425 kWh/month
Total power consumption is 58.45 kWh or about 5 €/month.
In models fitted with a tap water connection, the only power consuming function is the lighting.
