At 10,150 sq. feet the double-sided hydroponic green wall completed by Green over Grey in 2013 is the largest outdoor living wall in North America. A custom-made platform gantry was used to install and maintain one of the most biologically diverse living walls in North America. Some 50,000 native plants across 120 species grow hydroponically. It’s been calculated that the wall is sequestering the same CO2 as 47 medium sized trees.
This photo was taken before spring maintenance. Normally that takes a week and may involve replacing 5-10% of the plants, a number that could be higher in a bad winter. Planting outdoors is from March until August
Mountains & Trees, Waves & Petals was installed as part of Guildford Town Centre’s LEED Gold certification.
