Extra 4 Groups of Top Hoops Equipped

In addition to the 3 rows of stable top crossbars, 4 additional groups of top hoops are added, preventing damage from snow & rainwater accumulation. Also, the ground greenhouse frame secured by the U-shaped ground staples will effectively grip the ground and reduce wind obstruction. Stability has been greatly improved.

Top Cover Reinforced with Oxford Cloth

To avoid tearing at seams, the 100% waterproof firm Oxford cloth is sewn to reinforce the greenhouse cover. With the waterproof, UV-resistant agent and translucent mesh cover, up to 85% of the sunlight can pass through. The service life of cover is significantly increased.

Fully Sealed Windows and Doors

With all-sided velcro on the windows, the greenhouse can be heat-locked and keep a relatively higher temperature in winter than the outside. Meanwhile, the velcro and greenhouse cover buckles on the doors can make it airtight. Ventilation can also be achieved by 8 flexible screen windows when needed.

Friendly advice

1. The positioning of the front of the greenhouse should NOT face in the direction from whence the wind predominantly blows.

2. We recommend you purchase additional anchoring materials (stakes, weights, screws, etc.) locally or use compost, manure, topsoil, bricks, etc... around the sides to enhance the stability.

3. Find other attractive greenhouse tents at Quictent, such as 12' x 7' x 7' Tunnel Greenhouse and 71" x 36" x 36" Mini Greenhouse.
