Proven green wall technology. The Versa Wall is primarily used on interior applications, but may be used in warmer climates, in protected exterior venues. Versa Wall is user-friendly, easy to install and maintain due to the flexibility of 4″ (10 cm) pots that can be placed directly into the Versa Wall tray without any ‘re-potting’. In addition, Versa Wall remains beautiful year-round as plants are interchangeable according to season. User-friendly. Ultra-easy install.
