Taller crops in a Bonanza 1m2 need more vertical room, and this set provides it. Fitting the panels raises the cabinet 56cm to a 232cm finished height, freeing space above the canopy for bigger plants or a higher light mount.
The kit ships with a fresh set of back panels, drilled for the air inlets. Outlet and cable entry points are cut into the extension panels themselves, which keeps the build tidy and the airflow correct. A matching lock is included.
