This is an ERECTOR set assembly. Directions are not great. Multiple "take aparts" to get it correct. Really do need to have a mechanical aptitude to get this assembled. Once together, it is very nice and works as advertised; especially for the price point.

We are pleased with this greenhouse. The instructions weren't too great but overall it is strong and does the job. One suggestion to the manufacturer..... the bolts that stick outside into the "rain gutter" are rusting immediately. Change to a galvanized bolt.

This product could be a 5 star product if they addressed three issues. The first has been mentioned by several other reviewers. The instructions aren’t very clear and it takes a bit of studying to understand how it’s meant to be assembled. The second issue is that the structure isn’t very stable in high winds (30-40 mph or more). I had 3-4 inches of sway and the center ridge angle bracket buckled during one particular gusty day. I remedied this instability by adding internal guy wires across the length and width walls to both square the structure and add substantial rigidity. This was done by using 1/8” stainless steel cable and turnbuckles attached to the structure as an “x”. Now under 60+ mph winds it barely moves. I feel this should be part of the design especially since most people installing these greenhouses probably live in areas where there’s substantial wind during seasonal weather changes. The third issue is that the side wall panels and roof panels are too short. The sidewall panels appear to be 1/4-1/2” too short. The roof panels are 1/8-3/8” too short. When the side panels are fully seated in the groove in the base, the top of the panel is short of the top groove by about 1/8”. The result is that the panel flexes at the top due to a lack of support by the groove and if you push hard enough, it bows enough for the sides of the panel to slip out of their grooves. The first windy day blew several of the panels out of the walls. I attempted to put a shim in the bottom groove so that the panel would “sit high” in the groove so the panel would engage in the top groove, but it only ends up with about 1/16” of engagement in the top and bottom grooves, which is not enough to prevent the contraction during low temperatures from causing the panel to pop out of the top groove during windy conditions. The roof panels also move and flex with the wind causing them to also pop out of their grooves although they seem to be less problematic than the side panels. I’m making some additional modifications to keep the panels restrained but all of this extra work could have been avoided by providing slightly longer panels. If the manufacturer would remedy these issues, this would be a 5 star product. It’s visually appealing and the overall quality seems to be good. I had all of the parts and no other real fitment issues. Once I’ve secured the side and roof panels from popping out of the grooves, I think this product will last quite awhile.

I have put together many things with bad instructions, but none compare to how ridiculous these instructions are. The pictures are not helpful and often did not look like the parts that were called for. I finally got it put together the day before yesterday, however, I cannot get the vent to stay attached. Yesterday was windy and rainy and the vent blew off. If I can't get it easily attached again without taking anything apart, or I'm unable to get it to stay attached, I'm taking the rest of it down and sending it back. I also had to go to the hardware store to pick up more nuts for the bolts because not enough were provided.

Nice when completed but putting it together is another matter. The instructions are VERY misleading and not at all helpful. Love the finished product but unless you want to spend DAYS putting it together, would not buy it.

EDIT: now August 5, 2025. Greenhouse is still standing strong. I recommend siliconing around the panels to keep them sturdy. The only complaint I have: the vent panel that lifts on the top comes off in wind if not secured some way other than the latch and is very hard to get back on. Overall still very pleased! Original review: I will agree with the other reviews that the instructions leave a lot to the imagination, but once you figure out the main gist of things, it moves right along. It took my husband and I four evenings to put it together. Everything showed up in two boxes with everything in great shape. I must admit, taking it out of the packaging I thought it might be wimpy or cheaply made, but now that’s it’s all together, this thing is sturdy! So far it’s done well with 20-25 mile wind gusts. I’m looking forward to filling it with plants! This is a great buy if you’re a quick learner and good with puzzles! I would recommend this. Invest in a drill and some bits!
