Sized at 11.48 x 6.56 x 6.56 ft, this walk-in tunnel greenhouse gives you enough room to stand upright between rows while starting seedlings, potting flowers, or overwintering tender plants. The galvanized steel hoop frame includes a top beam and 2 diagonal poles for added rigidity, and ground stakes with guy ropes anchor the whole structure so it holds steady in open yards. A 140 g/cm3 PE cover wraps the frame to block UV rays and rain while trapping warmth on cold nights, and 6 roll-up mesh windows paired with a zippered door let you open up the sides for cross ventilation whenever the weather turns mild. Weighing just 28.2 lbs, the kit assembles with included connectors and scratch-resistant screw covers, so a single gardener can have it staked down and ready for planting in an afternoon.
