Nice tent. Well made and heavy zippers. Bought it to try to keep our planters from freezing over the winter and killing the plants. Guess we will see if it works in a few months.

We have this item on our back porch, and we use it for our outside Cat who loves being outside, and has a customized A frame heated house with his own deck and on legs inside the green house. The heated home keeps him warm and the green house gives him added protection. Of course during very low cold temperatures and or snow, I bring him although he hates being inside. Recommend this item!!

I'm kind of shocked by the positive reviews. The steel rods for the frame are very lightweight and are not sturdy at all, especially for the price of this thing.I barely had the greenhouse up for a month before a wind storm hit my area. Despite the steel wire being tightened to the ground anchors as tight as humanly possibly using a wrench, all four of them slipped through their locking mechanism and the thing flew away. It didn't fly far at all, yet it ending up completely bending one of the rods in the frame.If you live somewhere with absolutely no wind it might be fine, but it still feels overpriced.

I found that this 6x4 size was just perfect for my space and for starting seed trays. The bars of the frame are very strong and seem well made; however, they do not use bolts like the picture suggests. The frame came apart several times while assembling as a result.The instructions do not clearly explain some steps (such as where to place the cross bars) which made the process take longer.Once placed, I used the auger anchors to help secure the green house to the ground. Wire rope came with the anchors but did not reach the cross bars, so had to improvise.Additionally, there are no loops or built-in ways to attach the greenhouse cover to the actual frame and base. Typically you'll find sewn-in ties or loops on the inside of the cover material. But none here, so there is no easy way to anchor the cover to the frame. It is a tight fit, but with our strong winds, we can't take chances with the cover coming off. This was very disappointing. We'll need to configure something that will work.Overall, I would have expected a better system for attaching the cover to the frame. But the quality of the materials is very good. We have high hopes for this one!

The greenhouse overall is great quality, not too hard to setup but two people will be best to finish it within 30 mins. Canvas is in good shape. I do hope zipper handle is both side so I can open window from inside. The bottom is not sealed though so i do find small animals come in and grabbed one spring onion. I might seal it afterwards

I needed a small compact greenhouse to keep my plants alive during winter since my garage wasn't warm enough. ( I live in Texas)Easy to assemble but recommend two peopleKeeps warmHeavy enough where it will not turn into a kite (stakes are included just didn't get around to it yet)One negative would be, I wish it came with a fabric floor to give it an extra layer from the elements

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.

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.

the area that needs improvement is the (4) round sleave-in feet, I would prefer them to be in metal as the remainder of the frame.
