Vivosun Grow Tent S558 | 5' x 5' x 6'8"

Outgrowing a 4x4 tent doesn't have to mean jumping straight to a full-room build. The Vivosun Grow Tent S558 gives you a meaningful step up — a 5' x 5' footprint under a fully enclosed, light-proof shell, with room for more plants or bigger canopies without the space or cost of an 8x8. Upgraded hexagon-pattern Mylar rated up to 100% reflectivity diffuses light from multiple angles across the larger floor space, so the extra square footage doesn't come at the cost of even coverage.

The shell is built to match the added scale: 1680D tear-resistant Oxford fabric, PE reinforcement over 17μm, and a 400g high-density inner layer keep light blocked and the fabric durable through repeated use, while all-metal frame connectors and reinforced top hanging bars support heavier grow lights across the wider 5' x 5' span without the frame flexing.

Multiple duct ports and flexible cable openings make it easy to run an inline fan, humidifier, or heater to manage a larger grow space, and the transparent viewing window lets you check on plants without opening the tent. Bottom vents and removable mesh covers keep airflow and cleaning manageable at this size, and the S558 still sets up in minutes with no tools, plus an included tool bag.
