CultiBox D-Series 120x120x200 is a 4x4 ft class indoor grow tent designed for easy access and clean airflow management. The D-Series layout adds two zipped side openings so plants can be reached from both sides, and uses lower mesh vents with Velcro to admit passive intake while reducing interior pressure. The tent provides a highly reflective inner lining to improve light distribution and an opaque exterior to block light leaks. For the 120 cm model, CultiBox specifies one adjustable intake port and two adjustable extraction ports (≈230 mm), plus two cable pass-throughs (≈100 mm). Dimensions are 120 cm wide by 120 cm deep by 200 cm high, giving 1.44 m² of canopy area.
