  • I’ve never put something together like this before……
Size: 4' L x 6.25' W x 6.4' H
This took me a minute to figure out. I’m 70. Alone. Female. No tools. I highly suggest using an electric drill. (I actually put this together with the Allen wrench provided, so it can be done but took me awhile.) You’ll probably also need a rubber mallet to get some of the plastic pieces in (or apart, if you put the plastic pieces on the wrong corners like I did). Organize all the parts carefully when unpacking. Everything is labeled, but if there are, for example, three of something, only one will be labeled so you have to have your systems in place. I organized all the pieces in the house and brought out only what was needed for the next step because the panels can blow away. (There is a film on both sides of the polycarbonate that will need removal, btw.) I misread/misinterpreted the diagrams in two strategic places and had to backtrack, which was frustrating, but managed to undo enough to switch support pieces and hobbled along until it was done. I can’t emphasize enough how important it is to caulk every seam, inside and out, when you’re done. I don’t know that it could handle much wind if you didn’t and it would be really loud and probably would let rain in. It goes from rattly and unstable, before caulking, to being a tight, sturdy, really sweet green house if you do and even though it took a lot of time, I think it’s essential. Go slow, don’t force anything. Make sure every polycarbonate panel is cleanly within the aluminum slots. I’m so pleased with the design and functionality. I got it to overwinter my citrus and some tender plants and am happy with my purchase. It’s not easy to put together alone but doable. I recommend this product. Good luck. ... show more

  • Looks nice
Size: 6’ L x 6.25' W x 6.4' H
I set it up by myself on a slightly windy day, it took me about 7 hours to do it by myself. (Any amount of wind before its put completly together makes it difficult without someone else there because the pieces will bend, they do bend back though) Some of the labels for the pieces where mislabeled which made things more interesting. I managed to get it done all by myself though and it looks great! There's no way of attaching it to the ground so we'll see how it holds up to a good ol' fashioned midwest storm. Happy with it so far and would recommend hopefully if you get this product you have a buddy or two to make things go more smoothly and less time consuming lol ... show more

  • Worst 300 dollars ever spent
Size: 6’ L x 6.25' W x 6.4' H
Really big disappointment after I saved so long. Not anywhere near worth the money. They don't package it appropriately for the "windows" nor the aluminum....aluminum shows up dented in multiple spots you will definitely need needle nose pliers to try and straighten it out and make it still usable and the windows with the special uv tape stuff on them show up ruined...peeling off to where you have to smooth it out best you can but it looks like crap and some of it has holes or corners missing...even if you have multiple experienced builders working on it a lot of the seems won't line up because both the windows and aluminum are a bit warped like the way wood does when it gets old or is left in water. The directions were terrible...half the time they tell you to put what goes on the left on the right it's opposites constantly so watch for that...and when you get to the part of installing the top window that opens and it has no arrows or instructions...look at the side without the "leg" on it and match it to the top supporting beam..it has to slide in from the side before you attach the black plastic pieces at the end and it doesn't tell you..so in the end you try to pop it in but it wont...also take care with sides..since the cheap uv windows are bowed and the screws are terrible. Oh and the gutter holes don't line up in the end either.... ... show more

  • Surprisingly sturdy little greenhouse. Very pleased!
Size: 4' L x 6.25' W x 6.4' H
Bought this greenhouse primarily as a place to sit outdoors in the winter and be protected from the elements in the northeast. Add a small heater and its very comfy. Manual is completely picture based, which isn't a bad thing. All parts were labeled well and the manual referred to each of them easily. Did find that a 2 pieces were referenced incorrectly in the manual or were labeled wrong, one or the other. That was a setback for about an hour while I tried to make it work as the manual suggested but the pictures showed something different so I went with the obvious fit and it all worked out. I spend about 2 and half days putting this together in between other things. I'd say it took me about 8 hours total to do it right and gently get all the window panels in place without bending them. Overall, very pleased and surprised by just how sturdy it turned out. Time will be the ultimate test. Some helpful tips. Keep everything loose until you're sure you have it right. Tighten when its all together. Press things firmly together and gently bend those window panels to fit in. Some will slide, some will not. The mis-numbered parts were something like 5 and 4a or 4 and 5a but you'll see when you go to follow the instructions that the angles at the top of the standing poles have to follow the roof line. A few extra bolts and screws were given which was also nice but made me panic a bit when I was done and they were still there. Guess I'll hold onto those just in case. I anchored mine to my deck and used the two provided anchors. Keep in mind those anchor on the inside of the greenhouse, not the outside. Lost some time there too trying to make it work the other way. Kinda like them better on the inside anyway since they are out of the weather. My only complaint really is the lack of ability to flip-flop the door opening. Would like to have had it open the opposite way but because the door frame is part of the roof support, and because its angled to follow the roof line, you have to put it on that way only. I'll make do. Not a huge fan of the roof opening either as it appears to stay closed only by gravity and I'm concerned the wind will catch it. You have to put the opening on the specified back right side only because of the way the rest of the supports are. Would have liked to put it on the left side but then the door would be in the wrong place. Small complaints really. Overall, a very nice greenhouse / sunroom and well worth the money. Just be patient and take breaks when you cannot be patient. It comes together and is worth it in the end. Would buy again. ... show more
