Rated 5 out of 5 by from Perfect for my tomatoes! We are going to our 3rd winter with this greenhouse and are very pleased with it. Took us quite a bit longer to erect than stated. We erected permanently by bolting to metal t posts driven into ground every other leg. We have extremely high winds to 80mph, sometimes more and didn't want it to blow away! Noting that literature says to take down in winter, we are pleased at the durability having weathered 2 whole years in the High Desert Outback of Oregon. Cover still in great shape. Highly recommend.

Rated 5 out of 5 by from Perfect! This is our second ShelterLogic greenhouse. Our first one has been through 2 full seasons and the shell is beginning to show wear. We will order a replacement for it at the end of this season. We chose this style of greenhouse over building one from scratch for several reasons, not the least of which was assembly time. We are glad we did. Our first was a 10 x 20 of the same design. They have both been easy and intuitive to assemble, quick to arrive, and quite serviceable in various seasons. The price made it possible for us to get started at least a year earlier than we otherwise would have. We did not rely on anchors that came with the greenhouse. We poured concrete footers and bolted our frame to eyelets. We live in a high wind area, which was one of the reasons we felt the need for a greenhouse. The zip vents are great, though this year we added a gable fan which we hung from the rafters inside. We chose a wider, longer greenhouse for our 2nd because we wanted to experiment with permaculture. We built a perimeter raised bed 29" high and mounted the greenhouse on it. We highly recommend ShelterLogic products, as they are of reliable quality, have standardized replaceable parts, good customer service, and extremely affordable, compared to conventional hard-sided styles.

Rated 5 out of 5 by from Great Greenhouse This is a great greenhouse. We built a wooden frame, leveled the ground filled it with sand and put paving stones down for a floor. When we assembled the greenhouse we screwed the tubes to the wooden frame. The greenhouse has withstood winds of 40,50 mph with out a single problem. It has excellent cross ventilation and our plants have been protected from the cold down to the low teens with just a small heater.

Rated 5 out of 5 by from No more veggies for the deer Great little greenhouse - easy to put up. looks nice in the yard and is pleasant to work in. Unless the deer learn to low crawl or unzip the door looks like we might get more peppers, tomatoes and herbs than they will for a change. Only thing that could make it better would be a zipper window on each side.

I want to buy another greenhouse, my only concern is that the last cover didn't even last two years. How do you keep the cover from tearing where it meets the bar on top, and by the zipper. Thank you

Asked by: Mary 007
Hello Mary, By ensuring that the cover is properly sitting on the frame it can elongate the life of the material. In most cases if the cover is too tight or too loose you will see the tearing occur. For troubleshooting or assembly support we are available 7 days a week at 1-800-932-9344. Thank you
