Each plant has some special requirements and critical needs. So, the first important issue is to choose various plant species having the same special requirements and critical needs within a living wall. Secondly, the plant species used for indoor projects are different from those used for outdoors. Therefore, based on the huge experiences we have gained during the years on this very important field, we will advise you on choosing the right plant species based on the specific conditions of your project as well as your personal interests and favorites.
Based on your personal interests and favorites, you will have three main options for your project concerning its performance system which include "non-smart", "smart" and "full-smart" living wall systems. Furthermore, based on the the availability of the main perquisites of irrigation & nutrition system, e.g. water supply, drainage point, etc., at your property, you will have an "open" or a "closed" irrigation & nutrition system.
Our non-smart living wall system is a lightweight hydroponic living wall, having a multi-layered structure in which the plant species can grow throughout a hydroponic skin, in a water based, nutrient rich solution by the support of an inert medium such as perlite, rockwool, clay pellets, peat moss, or vermiculite. In this system, irrigation and nutrition of plant species are done manually without using any smart system. Alternatively, it is also possible to automate the irrigation part only, if there is water supply available at the site. However, nutrition of plant species must still be done manually in this case.
Our smart living wall system has all the details and specifications used in the non-smart living wall system concerning the whole structure of the living wall, plus an extra feature by which it is possible for the user to send irrigation, nutrition, and lighting orders to the living wall via our Higreenwall Smart Controller by manual setting of the mentioned orders on our Higreenwall App.
Our full-smart living wall system has all the details and specifications used in the non-smart and smart living wall systems concerning the whole structure of the living wall, as well as all the features used in the smart living wall system, e.g. sending the irrigation, nutrition, and lighting orders to the living wall via our Higreenwall Smart Controller+ using our Higreenwall App+, plus three extra specific features: (1) In our full-smart system, it is possible for the user to receive several regular reports from the living wall regarding the actual amounts of irrigation, nutrition, and lighting, with the help of various sensors embedded within the hydroponic skin; and (2) Our full-smart system uses Machine Learning (ML), as a branch of Artificial Intelligence (AI) technology, to continuously monitor the latest condition of the living wall based on the data collected by the sensors, self-learn the user’s habits based on his/her previous orders, automatically reset the orders, and send them to the living wall via Higreenwall Smart Controller+; and (3) In our full-smart system, Higreenwall App+ receives the signals of any probable problems related to electricity outage and/or water leakage from Higreenwall Smart Controller+, and alerts them to the user through SMS and/or push notifications.
If you choose to have a living wall with an "open" irrigation & nutrition system, then you have to prepare several main perquisites such as the water and power supplies, a suitable drainage point, as well as sufficient ambient lighting. In case, you cannot prepare a suitable drainage point for your living wall, then we have to consider a "closed" irrigation & nutrition system. In addition, for any living wall system, your location must have sufficient ambient lighting. However, if there is insufficient ambient lighting at the location of your living wall, then we have to simulate the sun light for your plant species by the use of some lighting projectors.
After finalizing the installation process, and training you on how to use and control your living wall system, we start our initial maintenance services for free during the first period of 1-3 months including one visit per month. Once the 1-3 months period of the initial maintenance services is finished, you may decide to extend our maintenance services for a longer period of time, e.g. 6 or 12 months, by signing a regular maintenance contract with us. In such a case, we will take care of everything for you, and there will be no reason for you to be wondering about the maintenance operations of your living wall.
No, you don't have to necessarily continue with us for our regular maintenance services. This is fully up to you, and you may decide to do it by yourself. Don't worry! If you decide not to continue with us, we will fully train you on how to maintain your living wall by yourself.
In case of occurring any probable problem during the maintenance period, you will let us know the issue by calling on the phone, and we will send our maintenance team to your location, as soon as possible, to investigate and solve the problem. If we find out that the problem has been occurred due to any reasons covered by our warranty policy, then you have to pay nothing for such services.
