This walk-in tunnel greenhouse provides a generous 15 ft. x 6.5 ft. x 7 ft. growing area, ideal for extending your gardening season. The upgraded galvanized steel frame uses 0.8 in. diameter hoops with three top beams and diagonal poles to deliver exceptional stability against snow and wind loads. Eight mesh roll-up windows and a zippered door allow adjustable ventilation, keeping plants cool and reducing humidity. The waterproof PE cover blocks harmful UV rays and sheds rain, while its snug fit retains heat during cold months. Assembly is straightforward with all connectors, ropes, stakes, and guy ropes included; tighten screws only after the frame is fully positioned. Weighing just 37.03 lb, this greenhouse is portable and easy to relocate. Use it for starting seedlings in early spring, protecting tender perennials in fall, or growing cool-season crops through winter in your backyard, community garden, or small nursery.
