I absolutely love this 4x6FT outdoor greenhouse! The size is just right for my small backyard, yet it provides ample room for my herbs, tomatoes, and flowers. The polycarbonate panels are sturdy and let in just the right amount of sunlight while protecting plants from harsh weather. I was pleasantly surprised by how easy the quick-installation structure made assembly—took just a few hours with a friend. The vented roof window is a great feature for airflow and temperature control. The aluminum frame feels solid and windproof. Highly recommend for any hobby gardener looking for a reliable and attractive greenhouse!

Update: they gave us a very nice discount for the issues we were having. Now that I’ve had it up and set up for a while it is very nice. The skylight vents don’t stay in so I decided to take them out until it gets cold. But the greenhouse itself holds heat very well. I don’t think I’m going to have any problems with heat in the winter. We used silicon to fill in all the gaps. I really do like it and it is very nice. I got the 10x12 and it’s okay. Definitely not the best design. I don’t know if we’re doing it wrong or what but the vents at the top don’t latch. There’s few gaps within the frame. The worst part was putting it together. It took my husband and I almost two days to put it together. There’s so many parts. The directions are terrible. They don’t show which way some parts go so we spent most the time trying to figure out which way certain parts go. We couldn’t go 1 step without having an issue. We build and put things together all the time and this was the hardest thing we have put together. On the up side, it’s very spacious and it looks very nice. It seems sturdy but I live in a fairly windy place so we’ll see. We had to use our own anchors bc it only came with ground anchors, not concrete anchors. But it seems like it will be good and I am very excited to get it all set up and started!

We are currently in the process of building this greenhouse and here are a few suggestions. The directions aren't written so be very careful to follow the pictures. Inventory all items before you start. If parts are missing or broken, call or text the number available. The customer service is very helpful and our one missing part and one damaged part are on their way. All parts are labeled with a small identifying letter/number. Keep those labels on until you have attached the unit to the frame. Remove them before sun or rain. They are easier to remove. The panels have protective plastic on both sides. Be sure to remove these covers before assembling. We had the two ends up when we were hit with 45mph winds. We had braced the two ends at the lower half with chairs and tables and had no damage when the storm had passed. The greenhouse seems to be sturdy and able to withstand serious weather. btw, we are a couple in our mid-70's and are doing the assembling ourselves.

This greenhouse is a good size for a small garden and gives plenty of space for plants. The frame feels sturdy and the panels keep the heat in well. I like the vented roof window because it helps with airflow. It works great for protecting plants and starting seedlings.

Don’t waste your money on this product! It can’t even handle a light wind. The materials are cheap, and the overall build quality is terrible. To make matters worse, the seller refuses to pay for return shipping.

Probably the worst directions of any large scale project I've ever had. The overall quality is ok. Some of the panels are a tad wonky with fit. But the directions were a nightmare and even had several places that we had to backtrack and redo pieces. It was not for the weakhearted. And many pieces and hardware parts were either not labeled or mislabeled. Also, the corner connectors are just cheap plastic. I would probably not repurchase this given what I know now.

Lots of parts and pieces but it was easy to follow the instructions. Installed a couple pieces backwards but easily fixed. All the parts were in the box! Very happy with finished product.
