  • Spacious greenhouse Spacious greenhouse
Color: Charcoal Black Size: 8×12FT
This is one impressive greenhouse and it's really nice. It took four guys to fix it and it took 6 plus hours to fix. They admitted it was tedious to put together but it turned out nice. It's spacious and looks sturdy but this baby gets hot real quick so he prepared to sweat while putting it together. Also, have at least 5 people to help put it together. ... show more

  • Greenhouse vs 60mph winds
Color: Charcoal Black Size: 6×4FT
For the price and what I wanted this was perfect! Putting it together - it’s challenging. I had to walk away a few times. Now the reason I decided to review this - we had 60 mph winds last night and while the greenhouse has some damage, I’m rather impressed how well it held up to strong winds, for the price paid, she’s sturdy! ... show more

  • This is the WORST!
Color: Dark Gray Size: 6×6FT
If you want a greenhouse, I suggest you buy something else. I have spent over 12 hours trying to put this together, about half of which I had help, and am not able to complete the assembly. Things don't line up properly and often don't fit or fit badly. The instructions are awful, badly drawn, and the order of steps often makes no sense at all. This is the worst purchase I've ever made on Amazon. I've missed the return window so have to suck up the money spent and I have nowhere safe to put the seedlings I started to keep them safe from the deer. Wish I'd gone with something else. Do yourself a favor and a save time and frustration by maybe buying something simpler or more expensive. I would have gladly paid more and saved myself this wasted effort and time. Now I have to take it apart and throw it away! ... show more

  • Price and quality Price and quality
Color: Charcoal Black Size: 6×4FT
It is better than the plastic bag greenhouse however as previous purchasers have stated: not true to advertised measurements 5'6 x 3'7....so not quite 6 x 4. Also the window has a gap because it won't sit properly/ window is larger than the hole... so it just kinda sits on top and creates a gap where one side falls in place while other side over hangs. overall I am happy with it; I just finished it today. My daughter helped me(yes it takes 2) and it took us 5 hrs because the directions are limited to confusing pictures/ so you have to have a little common sense when thinking how the directions are implying... I am not sure quality will last more than a year or 2 given I am in Georgia we do not get harsh weather usually. But the polyurethane panels are thin and very bendable and seem to want to slide out of track if you accidentally push or rub against them. Door is also not perfect. I think for the price it is quite nice and I will get treated lumber to shore up the base a little better. *** make sure base is level (this helps with assembly and sturdiness) ... show more

  • Garden game changer.
If you are wondering if you should get an entry level, hobby greenhouse, do it. After having this one for a growing season, I wish I wish I had bought one sooner. It has been a complete game-changer. I put it together alone (which can be done without major issues) but two would definitely make it easier. I was worried about it withstanding wind and such but it has withstood some wind and heavy rain like a champion in grow zone 8a. I installed it on a brick foundation and screwed the base to treated wood that is fixed to the brick foundation. I have been pleasantly surprised with this little setup. ... show more

  • Easy-to-assemble mini greenhouse Easy-to-assemble mini greenhouse
It took me about 5 minutes to put the main frame of this mini greenhouse together. The UV-resistant polycarbonate panels seem well-constructed and durable. Hopefully, it will last a few winters in the Northeast.

  • Lay out the parts, organize and pull the plastic film off BOTH sides of the panels!
Color: Dark Gray Size: 6×6FT
Great value! I made sure to check for all the parts, laid them all out and organized them based on the steps in the instructions. I agree the directions are vague, however I was able to put the entire green house together by myself in about 5 hours. Be sure to anchor the structure first thing! I chose a windy day and had half the structure together when it took flight, traveled about 20-30 feet rolling like Dorothy’s house and then landing. I was amazed to see it held together. Once it was assembled, it’s very sturdy and didn’t budge through 2 storms. Make sure to pull the plastic film off both sides. The white cover faces the inside and is not marked but it comes off like the outside that is marked. If you have trouble getting the panels to fit just loosen up the cams and screws, and then tighten once everything is in place. Overall very happy with the finished product. I love the vent in the roof, the door lock and the gutters. I added rainwater collection barrels and ran hoses from the back down spouts. 5 stars and I’m a Karen. ... show more
