Here’s another installation of an indoor green wall using yet another method. They’ve got a custom built drip tray to catch all the water, and from there I’d imagine they’ve got a pump on a timer to periodically send the water back up and through the system again. With this type of system, the only maintenance you need to do is top up the water in the resevoir about every month or so as well as add more nutrients to the water. With a system that big, they’d probably check the PH levels to ensure the plants stay healthy.
