At 9.8 x 6.6 x 6.6 ft, this walk-in tunnel greenhouse is sized for smaller yards and patios while still giving you enough headroom to stand and tend plants comfortably. The galvanized steel hoop frame pairs a top beam with 2 diagonal poles to resist rain and snow buildup on the dome, and the kit includes ropes, stakes, and guy ropes so you can anchor it firmly to the ground. A 140 g/cm3 PE cover shields plants from UV rays, rust-causing moisture, and rain year-round, fitting snugly over the frame to hold in warmth during cold nights. Six roll-up mesh windows and a zippered door open up for cross ventilation on hot days and seal shut to protect seedlings from frost. Weighing 28.2 lbs, the frame assembles with connectors and scratch-resistant screw covers, making it manageable for one person to set up in a small garden bed or backyard corner.
