  • Survives Oklahoma winds
Size: 20' x 10' x 6.6' Color: White
A year in and the cover has a couple rips and tears but did AMAZING considering the price point. Great for a home medical garden. I recommend using 12-16 sandbags on the bottom rails and it will go nowhere.

  • Good with reinforcements (see video)
Size: 20' x 10' x 6.6' Color: White
The media could not be loaded. Like others have stated, the poles are a joke and very easily bendable. Be careful if you use a screw gun to save time because you will bend your poles if you overtighten. Don’t use the written instructions or step-by-step pictures for assembly. The only think you need is the first pic at the top the has the numbers on it. Two of us put it together in a little over an hour. The stakes and rope that come with it will not be suitable for this application. We purchased 12” spiral tie down anchors (another $60-80) because we have very high winds. We ended up using the rope because I thought it would be fine, but we snapped a couple of pieces tying down so I’ll be replacing that soon. The anchors are at every point and holding well! Cross-crossed the rope over the top and tied down. Lastly, we put what broken bricks and blocks we had around the outside. I’ll need to get some more. The plastic is fantastic! Went on very easily and I love the double doors and zipper which will be very necessary for us to use come summer. The only improvement there would be is to add more Velcro at every cross section to help hold the plastic to the frame. Right now there is only Velcro at the ends. We reinforced the frame by adding an additional conduit header (I was floored how much stronger this was) and middle column support poles. I almost wish I had just purchased or made a pipe bender and made our own conduit frame and then just purchased the plastic cover from the company to go on it. Probably would be cheaper in the long run. We had moderate winds last night with gusts at 50 mph and that will be increasing tonight. This morning, the only thing that came loose is the doors had flapped out from under their bricks, so I’ll add more there. Otherwise, structure is good and strong, albeit creaky in the wind (you can hear it on the video I made). I’ll update if things change. Update 3/19/2022: They are still holding strong! We ended up purchasing thicker 3/8” rope to tie it down with as thinner rope snapped a few times on us probably due to UV damage. This one is working well and should last several years. The winds have been crazy!! We are in the high desert so we see winds. The plastic has seen some damage this year because of it flapping and rubbing against the metal bars. I’m hindsight, I wish I had reinforced some of those edges with tape. I plan to use some greenhouse tape to patch up the holes from rubbing and reinforce a couple of edges, but I suspect I can get another two years at least with this plastic. One more thing: do not open the zipper to the very very top. This caused it to slip off its tracks. It’s easily avoidable if you always leave about a half inch still zipped when you open/roll up the doors. ... show more

  • Good for the price but 2 years later we need a repacement cover. Willing to pay fot it.
Size: 20' x 10' x 6.6' Color: Green
Easy to assemble and last for about two years. Made it through snow and wind storms. Hoping to find a replacement cover as this one is needing to be replaced. We would be willing to purchase a new one if someone could point us in the direction of a place where we could do so....

  • Great quality and design for the price.
Size: 20' x 10' x 6.6' Color: Green
Super impressed with the quality of the construction. All the zippers and seams are perfect and seem very sturdy. Great design with the doors and windows to adjust airflow. Everything fit together perfectly. The metal frame seemed a little wobbly, and I thought they could have added an extra crossbar or 2, but once the plastic was on, it held it all in place really well. I like the way the there is an extra foot of plastic all around the perimeter. I put heavy rocks all around, on top of the extra plastic then covered with wood chips. It looks really nice, and I'm confident it won't blow away. We've already had some strong winds, and it hasn't moved at all. The instructions are not the greatest. I wish they would have added a few more pics. But the overall assembly was pretty easy. Just go slow and use your common sense. I'm a 55 year old woman, and I did it by myself. ... show more

  • *UPDATE* Poorly made product
Size: 20' x 10' x 6.6' Color: White
*After submitting the review below, I was immediately contacted by Quictent. Jasmine from customer service addressed my concern immediately and sent out a replacement cover at no charge. The customer service is wonderful, they do their due diligence to keep their customers happy. I will provide further updates once I replace the cover and have used it for the upcoming growing season.* I had issues with the cover straight of the box. The zippers of the cover were broken, and rusted. I contacted the company and they promptly responded to my complaints. With little difficulty, the cover was replaced. However, this cover will not last long in the elements, following a warmer than usual summer, the plastic began to crack and the zippers started to snag. Before the end of summer, the zippers were non functional on one side. Now, one side is blocked with a tarp because the doors can't close which leaves my plants exposed to the cold weather. I contacted the company again, I was told the warranty for the cover is six months and I will need to purchase the replacement. The cover is not good quality, it rips easily when exposed to the elements. For a cover that is made for outdoors, you would think it would withstand, wind, heat, and cold. This is a huge disappointment for me, this has caused delays in my growing. Although their customer service is great, I'm not sure if I want a replacement, I may need to find an alternative. Please don't purchase. ... show more

  • Great value and excellent customer service
Size: 20' x 10' x 6.6' Color: White
The tent has been a great solution for my citrus trees. It was easy to set up with the help of my daughter. It has been keeping my trees, healthy and 20° weather. One of the zippers broke in the first week, and I received fantastic customer support from Martina, who immediately sent me out a new tent cover to replace the defective one. Overall, I am extremely pleased with the greenhouse, and with Martina! ... show more
