Aim
Gaining better knowledge on the existing systems and
map the benefits and disbenefits of each system.
Researching the challenges vertical green wall producers
and installers experience and search for possible
innovations and improvements to cope with these
challenges.
Execution
Demonstration of 9 different Living Wall systems
Charactarization of these Living Wall Systems
(stress tests)
Trials on plant sortiment, substrate choice and
irrigation/fertigation

LWS common problems
Problem Solution
Drought problems in the upper part
of the system: gravity
Blockages of drip irrigation
At the moment we are researching
the possibilities of pre-filters and
disinfectants to decontaminate
multiple types of drip lines from
algae
