Walk-in Tunnel Greenhouse, 20 x 10 x 7 ft Portable Plant Hot House with Galvanized Steel Frames, 3 Top Beams, 4 Diagonal Posts, 2 Zippered Doors and 12 Roll-Up Windows, Green

Excellent Air Ventilation: With 12 mesh windows, our tunnel greenhouse can keep out small "disturbances" and increase cross ventilation and airflow. In addition, we have 2 foldable zippers for air to freely enter and exit. Keep your space clean from debris and make sure every breath you take is one to remember.
Upgraded Galvanized Frame: We upgraded the galvanized steel to 0.8" diameter and 0.02" thickness. This high tunnel greenhouse has 3 top beams to prevent rain and snow from accumulating on the dome. In addition, the diagonal posts can ensure stability during extreme weather. We have you covered, so get ready to watch your crops grow all year round.
High-quality waterproof PE: The walk-in tunnel greenhouse comes with a PE cover that can protect your plants from ultraviolet rays, rust, snow and rain all year round. The size of the cover fits the frame closely, which improves the warmth and wind resistance in winter.
All tools included: The arch greenhouse is easy to assemble with connectors, and screw caps can prevent scratches and rust. Includes 4 ropes, stakes and branch ropes for added safety, stability and strength. Note: Do not tighten the screws until the final position is confirmed.
