This 10 x 7 x 7 ft walk-in tunnel greenhouse is built for gardeners who want to water without hauling a can back and forth: it comes with 4 brass nozzles and a 26.25 ft hose that connect directly into the frame, offering 3 spray modes so you can mist seedlings or soak established plants. The Q195 galvanized steel tubing measures 0.5 mm thick with a reinforced center support bar, and ground stakes plus guy ropes keep it anchored through wind and rain. A 140 g/m2 double-sided coated PE cover blocks UV rays while staying waterproof, and 6 vent windows sized 11.8 x 11.8 in work with the roll-up zippered door to keep airflow moving and pests out. At 33.5 lbs, the frame uses bolted connections and end caps to go together quickly, with an extended bottom cover edge you can weigh down for extra stability outdoors.
