CultiBox D-Series 150x150x200 is a square indoor grow tent designed for easy, full‑side access. Two side zip openings and a front door let growers reach plants without entering the enclosure. The exterior fabric blocks light in both directions when closed, while the interior uses a reflective liner to improve light utilization. The frame is made from metal bars joined by corner pieces for straightforward assembly and durability. Adjustable duct sleeves and lower mesh vents with Velcro help manage intake, extraction and passive airflow, improving CO2 renewal and reducing internal pressure. Dedicated cable ports simplify routing electrical leads. At 150 × 150 × 200 cm, it offers 2.25 m² of canopy area for medium‑to‑large home gardens.
