Green Box HIGH 120x120x220 is the 4x4‑foot, extra‑tall (220 cm) variant in Green Box’s grow‑tent line. It offers a 120 x 120 cm footprint with added headroom for taller cultivars and for mounting larger fixtures or filters. Construction mirrors other Green Box tents: heavy‑duty steel frame with push‑fit corners, steel roof hangers and straps, double‑stitched 600D Oxford outer with 620D diamond/silver mylar reflective lining, removable mylar floor tray, double‑cuffed duct socks, and mesh‑screened intake vents with light‑proof flaps. An uplift irrigation bar and exterior hygrometer pocket are included. Official listings confirm multiple “HIGH” 220 cm models and a 120 x 120 cm format in the range.
