Machrus OGrow Greenhouses for Outdoors- Small Portable Walk in Greenhouse Kit for Plants- 4X6 Green Houses for Outside- Polycarbonate Greenhouse Panels with Sliding Door, Heavy Duty Aluminum Frame

Hi, I am a mechanical engineer who saw all the 1-star reviews bemoaning the assembly process - and I bought it anyway. For the first 30 minutes, I was amused at the cut corners - some of them, like the strut channel, actually can streamline assembly vs through holes (and it's cheaper to produce)! However, as time wore on and the metal-bending issues became worse and worse, I eventually found my frame on the verge of collapse so I'll have to grab some L-brackets and resume assembly sometime this weekend. That is, if the bending did not permanently damage the strut - which is paper-thin by the way. Assembly is a nightmare, there is no design consideration for leveling or weight distribution. No sub-assembly, no (or too few) brackets to provide structure. Maybe the thing is solid when constructed (doubtful), but assembly is literally not possible without a wealth of outside tools to prevent catastrophic failure. The "bolt-in-channel" design quirk is cute, but extremely inefficient to supply sufficient torque without stripping -- ESPECIALLY when the next step has a floating 6 foot pole attached on ONE end by ONE bolt. I chuckled that the majority of, if not all, bolts are designed to only slide in at an angle (because the designer hates the customer) AND the majority of bolts are not accessible for tightening up (because the designer hates the customer). I will give this another shot this weekend. Maybe, if everything goes perfectly, I can increase this review to 2 stars.

Can anyone tell me if you take the opal white film off the window slates? Instructions not the greatest. Glad everything was marked. Some of it took 2 people to put together. Seems kinda flimsy for the money!!

The first box I received had been taped up and was missing all bolts and connector pieces. A call to customer service (Machrus) was answered quickly and they sent an email for me to list missing pieces. It was determined that it was easier to send me a full new box. Pics are from the previous model I built. You must use the BILT app (android/apple) to build the greenhouse. Don't even attempt it with the written instructions. Even then there are a few things that you just have to try and figure out. I assembled a 4x4 treated lumber base and 2x4 frame against the house/wall attached to the concrete and stucco. I built and leveled the frame and filled it with crushed granite to have a solid base. Assembling on a windy day is an impossible task, so wait until it is still. You can do it alone, but it will be much easier with a second set of hands. I had an electric screwdriver/drill and an impact socket and it made things much easier than using the included wrench and screwdriver. Some things that took a while to figure out/weren't clear: * the top/corners and middle roof supports should fit tight against the horiztonal members at the very top and front edge. Do not leave gaps where they intersect or your poly pieces will not be sandwiched tightly and can come out. * when putting the poly in on the sides, start with the tallest piece and then move toward the front with the shorter pieces. Trying to get them in the channels of the metal pieces is easier this way. * the door fits on a protected channel in the top, but rests on the outer lip of the bottom sill. I kept trying to get the bottom to ride the middle channel but that causes the door to hit the side support. It seemed like the top/bottom would be designed in parallel but they are not. * the angle brackets that fit on the middle support and roof side supports have an offset hole. You have to make sure this hole is in the correct orientation for the top of the doorframe support or it will not line up. * when you peel the white film off the poly pieces, mark the "outside" edge with a sharpie or sticker. If the rectangular pieces ever come off or get flipped around you won't know which is the outside otherwise. The white film is the "outside", which I assume is treated differently, but I couldn't see any difference. Once assembled the greenhouse is pretty sturdy. I ran a bead of flexseal around the vertical seams to lock the panels into place on the second day of assembly. I hadn't done this on the first day and a few pieces flexed and blew out, causing me to have to dis-assemble and re-assemble parts to get them back in. I also drilled small holes around the outside bottom trim to screw the frame down to the wooden base.

Let me start with the positives, the idea about this is good. The assembly is Terrible. Whoever said that this was easy to assemble is probably paid for it. I have assembled many things with my wife and this has terrible instructions, even with the app on side. The frame is so delicate and the panels do not fit, even at 2-3 mph winds it was impossible to assemble it. We unfortunately have a base built for it , so will try to retrofit some solution for it, but I'd not recommend this to anyone. Unless you're out of work and want to spend 25hours assembling it, don't buy it.I had to bend it in 4 places , but as an engineer I made it work, it has lasted 4 months against winds , so I'll give it 2 stars

This was the worst purchase on amazon I have ever made. It was incredibly difficult to assemble, and seemed so flimsy as we were putting it together. When we finally got it together, and we followed directions on the app to a T, we thought "well it looks great and seems stable". Then the wind came and blew the thing to PIECES. I am hoping the company will replace the missing and broken pieces, so we can rig it back together and figure a way to fortify it. Otherwise this was a complete waste of money and 4 days assembly.

Garbage, do not buy!! Reached out to seller for a partial Refund but they said we had to return the product in full. Generally this is not a problem but my husband had four days of working on putting together and it was a million pieces. So this was just not an option. He ended up building his own frame and using the plastic. Seriously so flimsy and cheap it’s not work 250.00 never mind the 700.0 we paid. DO NOT BUT
