Built for growers who need real headroom, this walk-in tunnel greenhouse measures 14.8 x 6.6 x 6.6 ft, big enough to stand upright while tending rows of vegetables or flowers. The galvanized steel hoop frame includes one top beam and two diagonal poles that brace the structure for stability, and screw covers protect connectors from scratches and rust. Eight mesh windows plus a roll-up zippered door keep air moving through the tunnel, cutting down on trapped humidity while still keeping small animals and pests out. The 140 g/cm² PE cover fits snugly over the frame, protecting plants from UV rays, rust, and rain while holding in warmth through cooler months; it's not recommended for severe weather conditions. Setup uses connectors along with 4 included ropes, stakes, and guy ropes for extra grounding and stability, and at 37.3 pounds the green tunnel is manageable to move and position before anchoring it in place, making it a solid way to protect a full row of plants from cold and frost while boosting airflow through summer.
