Rosslyn high rise gets 2nd-biggest active green wall

The 780-square-foot wall — 66 feet wide, with a height that varies from about five feet to 19 feet — is more than just plants stuck in pots on a wall. The active green wall system recirculates air, water and nutrients to the plants’ root zone at a rate that forces the plants to actively perform their natural processes continuously.
