Grow Tent Pro 4x4 P448 (48″ x 48″ x 80″)

Vivosun’s Grow Tent Pro 4x4 P448 is a 48 x 48 x 80 in (121,92 x 121,92 x 203,2 cm) enclosure built for indoor cultivation. The Pro variant uses 2000D Oxford fabric lined with reflective mylar and features a larger viewing window, SBS zipper door, and cable-management slots. A 1-inch (22 mm) steel frame with extra support bars and an included high CFM kit improves rigidity and hanging capacity; the technical sheet lists 220 lb load-bearing and side doors for easier access. The P448 provides multiple duct ports (two 4 in and five 8 in) and pre-filtered air vents, and ships with a floor tray and filter straps. Vivosun recommends a 6-inch inline fan and pairing with 400–500 W LEDs (e.g., LumaLight 500W/400W or AeroLight 400W).
