Stretching 15 x 7 x 7 ft, this walk-in tunnel greenhouse gives serious backyard growers room for multiple rows of vegetables, flowers, or potted plants with space to walk, prune, and water comfortably. It ships with a built-in irrigation setup of 6 brass nozzles and a 32.8 ft hose offering 3 adjustable spray modes, so watering the whole tunnel takes minutes instead of a can and repeated trips. The Q195 galvanized steel frame is 0.5 mm thick with a center support bar for rigidity, and ground stakes with guy ropes secure it against wind and rain for long-term outdoor use. The 140 g/m2 double-sided coated PE cover lets sunlight through while adding insulation and water resistance, and 8 vent windows plus a zippered roll-up door keep air circulating on warm days. At 45 lbs, bolt-fixed connections and tube end caps make assembly straightforward, with an extended bottom edge for added ground weight.
