For the price this greenhouse is absolutely the best on the market, it is extremely sturdy, the black powder coated aluminum tube frame is exceptional looking, and with the fast click system it is very easy to assemble compared to others out there. The 10mm triple walled polycarbonate panels are amazing for sudden temperature changes and the light diffusion is next level. I am so happy I finally decided on this unit. I trust you will not be disappointed if you go this route as well.

I build 3 season and year round sunrooms for a living so I was definitely weary and skeptical during this selection process but as soon as I started unpacking and checking the parts my fears were put at ease, the customer service was some of the best I've ever experienced and with a project such as this I believe that is very important, Eric and the others there at ACF were so quick to respond and kept me well informed on the status of my preorder and shipping. A BIG THANKS to you all!

If you are researching, on the fence, or just interested in a professional hobby greenhouse, look no further, your search is over. You will not find a better structure for this price. I know I am a professional so assembly was probably a bit easier for me than it will be for most but I did 95% of it myself and in only 1 day! (one quite long and darn windy day too I might add, which I also don't recommend!). The entire project took much longer though, laying out and prepping the raised foundation, the pea gravel floor, and building the benches are the parts that took the longest. I recommend getting a second set of automatic vent openers on top of the ones provided in the kit and installing them straight away to avoid installing and removing the manual ones later. They make things much more convenient.

This unit is also extremely roomy, I designed two 32" wide/full length benches on each side and still have an extra wide isle almost 4 feet wide!

I truly couldn't be happier that I did my homework and went with this unit over so many others out there.

I expect to enjoy this greenhouse for many years to come with the proper maintenance and care and I am completely confident that you will enjoy yours as well.

Good luck and happy growing!

       

What sold me was the extra thick 10mm polycarbonate panels, solid frame construction, a real door, available automatic vent openers, and great customer service. I have had the greenhouse for about a year and it's great! Best value for the price and not cheaply made.

The only reason I don't give this greenhouse 5 stars is the gaps around the door and the roof vent frames. I'm not growing tropical plants in the winter but I do expect a fairly sealed up greenhouse. This is not. The base is square and level but I have half an inch to two inches exposed to the elements around these areas. I'm using aluminum tape to fix these issues, it’s an ongoing thing. I find it odd that the door and vent frames have channels in the steel instead of being solid construction. The rubber seal around these areas could be more substantial to help seal up drafts. I would pay extra for a weatherizing kit if available.

Eric is awesome and helped me problem solve some of these issues. And maybe I'm expecting too much at this price level. I dream of, but can't afford the Cross Country line of greenhouses. I wouldn't take my review as a reason not to buy this greenhouse (the pictures from other reviews look great and that may be what you’ll get). I'm writing based only on my experience so far.

This is not the first greenhouse I have bought and constructed by myself, but I expect it to be my last. The GM10 with one extension is lighter, better insulated and 1/3 the cost of the one I bought over 20 years ago, both being of similar size. Each and every piece of the frame was well machined, and it went together with no issues, other than the time it initially took to decipher the instructions. Every piece, including hardware, was labeled, which made the assembly go very quickly. The lightness makes it easy for one person to assemble but does not compromise the strength of the completed unit.

Technical support and the integrity of this company are stellar. I ordered the kit in May, but unforeseen surgery prevented me from unpacking and doing an inventory as is suggested until October. After I completed the project, I noticed that I had probably ordered and paid for two extensions but received just one. I called customer service, and they confirmed that I was billed for two but only one was shipped. They quickly offered to ship the additional extension immediately but when I explained that the greenhouse was now complete, and I was happy with the size, the representative refunded the cost of the additional extension without question.

I am beyond happy that I decided to do business with ACF and feel sure customer support with assist me if ever I need them in the future.

Love this greenhouse! It replaced my 15-year-old Canadian Cedar greenhouse with the identical footprint but new one has 10-foot ceiling rather than 6-foot. I've doubled my shelf space!

One assembly caveat - hardware for that wonderful ceiling-mount fan must be installed while assembling the greenhouse. The joints are too tight to add hardware without partially dismanteling the greenhouse afterward - at least, we can't figure out how to mount it otherwise.

On Dec 2015 I placed an order for a Grow More GM10 and 2 extensions. These shipped in 2016 and we installed it in 2016 and butted it up against a storage shed. We ran a concrete footer for the Greenhouse and the storage shed. I am attaching a finished photo from 2016.

I am also attaching a photo of Thursday, March 14 2019 Amarillo Globe News. We had sustained winds of 49 and 50 miles per hour with gust up to 80 miles per hour. You can see that number in the article below the photo in the paper.

We have a total of 8 vents, each vent has two (2) Univent openers attached. The Univent openers kept the vents from blowing off or being tore off. I am very happy with the sturdiness of the Greenhouse.

 

We love our Grow More Greenhouse. We are happy that we added an extension to the 10 x13 house, and also added a back door for easy access. The house is quite sturdy and also attractive. The Dutch style doors are a nice touch and very practical. Assembly was fairly easy. We especially liked the click-lock method. We are happy we made this purchase. It is a good value for the money.

   

This greenhouse is an exceptional sturdy priceless product due to the provison of spacious roof vents, 10MM triple wall polycarbonate panels and rigid hinged wide dutch door that makes it tough to compete with versus all the other models on the market. I wish I knew about this model years ago. But like they say better late than never. This product will certainly last a lifetime and bring many happy memories for vegetable garden growers like yourself. I want to personally thank Eric Gordon and ACF Greenhouse staff for their wonderful support and hospitality in making this greenhouse a success beyond my wildest dreams. There is a Santa Claus out there folks if you truly believe in miracles. Ho! Ho! Ho! Also, have a HAPPY THANKSGIVING too and looking forward to next spring for the best growing season ever and harvest.

 

This is not my first aluminum framed, polycarbonate panel greenhouse, but it is by far the very best I’ve ever had. The packaging was very secure, and assembly instructions were fantastic. The shipping was unbelievably fast. And the quality of the materials is absolutely wonderful. I ordered the 10x13 with one 6.5’ extension, and as a testament to the quality of these panels, I’ve been able to keep this greenhouse heated to 50F on 24F nights with only a 1500W electric space heater. The customer service also can’t be beat if you have a problem or question! I couldn’t be more pleased with this purchase.

 

Here is a picture of our GM10 with 1 extension. We plan to paint the foundation black along with all the pavers and three 55 gal. drums filled with water to retain as much heat as possible.

We really like the design and how it went together. Thanks for your help and support.

 

Purchased at the end of August, installed by myself over the course of 2 weekends and a couple evenings. Would have been easier with a second pair of hands, but I managed to get it done with only a few frustrating issues of having to read between the lines of imperfectly described diagrams and pictures of a few key steps.

Despite that, this was the best quality greenhouse for anywhere near the price point. Totally worth the effort. Good luck!
