    • Great greenhouse - nice size for back yard - Sturdy Great greenhouse - nice size for back yard - Sturdy
Size: 6' x 6' x 6'

I wanted a small but sturdy greenhouse to put my plants in when it gets below 45 degrees. Exotic and tropical hibiscus are sensitive to cold and that comprises a lot of my plants. Most greenhouses I looked at seemed flimsy but this one seemed sturdy and it is. Easy to put together. Temps dropped to 38 and it protected my plants. For the 'floor' I bought artificial grass and used plant stakes to secure it. Since I need to move it by myself, I used the steel cables provided and attached them to kettle bells. Has worked well so far. It has 2 bars on the sides that seem to allow you to roll up the cover so the plants get air. I would have liked to see those bars available for the back as well. It has two windows and that was helpful when I wanted to check on my plants without opening the whole door and letting cold air in. I bought 3 tier shelves which worked well since many of my plants are 12-18" tall. Very happy so far. ... show more

    • Sturdy and Heavy Duty. Would Recommend!
Size: 6' x 4' x 6'
This is super sturdy, good quality, the cover is thick! Good size. We get a lot wind where we are and it has not moved. The anchors and poles are heavy-duty. I got this while it was on sale, if I wasn't cheap I might buy it for the regular price. Great for storing plants for the winter. I live in the south so I put this over my bell peppers and jalapeños to see if I could over winter them where they are instead of digging them up. ... show more

    • Overall it is good.
Size: 6' x 4' x 6'
The reason that I give this a 4 stars because the stakes that comes with it does not hold down the greenhouse very well. I can come loose with the wind. Otherwise this would have been a 5 stars. It is very easy to setup. Zipper is kind of hard to pull down, but still good. It protects my plants through the winter mostly. ... show more

    • Excellent so far. Will updated after winter is over.
Size: 6' x 4' x 6'
Received it on time, shipped with no additional packaging other than its own box - very sturdy and arrived with no damage. Easy to assemble, clear instructions. Helps to have two people to put on the covering but can be done mostly with one person. Zippers seem sturdy but only time will tell. Anchored it to a 2x4 frame since I am using it on my covered patio for some potted plants during the winter. It should be protected from winds there. Will house 6 large potted plants with a temperature sensor and a small heater controlled by my home automation system to turn on when it gets below 40F. Watering is handled by an automatic drip system. Will try to update after a few weeks or a couple of months. ... show more

    • Great for storage of tools
Size: 6' x 4' x 6'
Very sturdy, keeps things dry, looks very nice, made of good materials. We are very pleased and purchased two of them. Holds a good amount, great price, and zipper is easy to open and close.

    • So close to perfect - but rust an issue.
Size: 6' x 4' x 6'
Two weeks in and rust has formed where segments attach. Greenhouse was well packed but some of the poles were out of round, bent and dented. Likely happened in transit. Gently eased them back to round but a few were still were a tight fit and resulted in the powder paint finish being scratched upon assembly -- likely a source where moisture expedited the rusting. The interior humidity has ranged between 29% and 50%. Ventilation is fair. Zippers are fussy and require extra light touch. I've my doubts that this will survive autumn and is likely a goner by winter. Set up was not difficult, instructions complete and I was so hopeful as it had so much potential. I'm afraid the rust will compromise the structural soundness as the poles are quite thin (which is wonderful for lightness and mobility) but it will collapse with the continued deterioration. ... show more

    • Too snug cover
Size: 6' x 4' x 6' - 2025 Model
Good design, very sturdy frame but isn't easy to put together. The supports are stamped with numbers for identification but they have blurred, so are hard to read. The cover is difficult to fit over the frame, it seems a bit too small so I am having trouble zipping the door closed. A good size for a small garden, I can fit 3, 5ft racks inside that can hold 24 flats of plants. If I can solve the door zip issue, it will be great. ... show more

    • Good quality
Size: 6' x 4' x 6'
This is nice, big and spacious on the inside, kept my plants in great shape and I love the window, just wish there was windows on the sides too. High quality, held up even with the ice and snow this winter. Kept my plants warmer than outside, but I did have to put a heat source inside. The only thing is I wish it came with built in shelves. But the whole thing overall is of a good quality. Get some sand weights to hold it down in high winds, and we put ours up against the house to help protect it with more heat and from some of the windy days. ... show more
