  • Great price/disposable greenhouse/ no replacement covers
Color: White
This greenhouse is a great price. The directions were confusing. I had to color on my directions with colored pencils to make sense of the instructions, then mark the parts with sharpie marker when i laid them out on the ground. Two people could put this together, but three is better. It did not withstand snowfall and collapsed, but it was a great first greenhouse. I would buy it again. If replacement covers were sold, that would make it a lot better. Then I could have taken my cover off to see if the frame would have made it through the winter. ... show more

  • Cheap metal breaks easy
Color: White
Very cheap metal that bends and breaks easy. Had some gusty winds and it broke in 3 places after only having it a few weeks. Even when putting it together the metal bent is screws went a little deep. Cheap product, not with the money. Now I have to try to salvage it with repairs and keep my plants alive. ... show more

  • Good greenhouse for casual gardening
Color: Green
The diagrams to build it were a little confusing, but I got it together eventually. The frame is light weight, but I think it will last a while. The plastic cover is still fine after the spring/summer growing season. The ties for the door and windows are garbage though. They all broke with the first use. Good for the price. I didn't want to invest a small fortune in a high end greenhouse when I wasn't sure how good of a gardener I would be. I had mixed results, but that wasn't the greenhouse's fault! ... show more

  • Amazing
Color: White
The QR code is not correct for the size I bought and the parts are also labeled differently from the QR code . Other than that the instructions helped greatly . I needed 2 people to build

  • Flaws
Color: White
Greenhouse is decent but has some flaws. The plastic cover rips easily. The zipper door constantly gets off track and is almost impossible to get back to working properly. All the ties that hold open the door and the window have all rotted off in less than a few months. So now I have to try and figure out a way to rig it so they stay open. ... show more

  • Green house
Color: Green
Was a booger bear to read the directions. Only input would slow and methodical when you go to put it together. Found that not tightening up tight is easier. The final result was well worth it. Thank Y’all

  • Very flimsy tubing with weak joints.
Color: Green
I read reviews and was cautious in purchasing this. It arrived with the 1/2" EMT (pot metal) tubing in poor condition. Ends were bent and collapsed to the point of breaking the metal and losing integrity. I went ahead and put the structure up on level ground and bolted everything together with a proper snug (not torqued) fit. The structure seemed strong enough to stand on it's own and I assumed the extra anchors and tie downs I purchased would benefit keeping the center of the cover from catching wind and becoming a sail due to the lack of hook and pile tape fasteners in the center of the plastic. I took the time to layout the cover and examine it for damage as well and found it to be the only part in good condition. After emplacing the plastic on top of the frame I noticed every joint began buckling from the weight of the plastic. I planned to go to a local hardware store to buy extra supporting pieces to drill and connect onto the extra bolt lengths inside the structure to increase integrity and lifetime of what I had planned to use for an aquaponic greenhouse and well housing. Unfortunately, within ten minutes of the plastic being installed, the joints on all but one half hoop buckled and caved in...no load, no wind, just the weight of the cover. I messaged the seller and am awaiting response...will update with pictures when I get off post today. Update: Pictures added and still no reply by seller. Will update after reply received. ... show more

  • Love it
Color: Green
After reviewing the reviews for this found a nice spot in my backyard where it will be wind resistant and we put the frame in the ground, tucked the flaps with the frame underground and used landscape pins to hold it. assembly was pretty easy after we figured out the directions (which aren’t that great BTW), we will see how it holds up to NC heat and humidity, it’s very roomy and I hope that my garden does well in it. I ordered the 10x20x7. Can fit about 30 (25 gal) grow bags with enough space to walk around comfortably. ... show more
