Kit arrived fast and easy to put together if you have a drill. Could use a latch on front but easy to remedy w two extra screws and some wire or string. Looks good and hopefully will protect early seedlings and fall extension of veggies. Smells good too. Cheryl. West Hartford, CT. Sat Mar 11 2023

So very disappointed in this greenhouse purchase. The metal is VERY thin. Bolts and plates are already rusting. Hasnt even been a month yet. Finished setting it up around Sept. 19, 2026 as we still had to finish prepping the area when it arrived. Wish I had sent it back before we even attempted to put it together. But we were hoping it would be sturdy once it was built. I bought it because it said heavy duty, price was good, had a 4+ review and wind rating was higher then most. We are retired, on a fixed income, so I try to be smart with big purchases. There's ALOT of room for improvement.. Lulu. FL. Tue Oct 06 2026

The cold frame greenhouse provides a big space to hold various types of plants, the top part of this greenhouse could be opened and closed, and two bolts on the two sides could be used to fix the top. On a rainy day, you could close the top to keep it away from the rain. Giving you a dream garden you dreamed of.

I’m happy with the product. I’m personally using it for indoor use. I find the top part doesn’t sit flush and the directions for assembly could be better.. Sanjeet. Chicago, IL. Sat Sep 19 2026

very light weight and flimy and some of the parts were bent and or squished. That being said, it looks pretty good and will get the job done, hopefully hold up, and will have to see what strong midwest winds do to it. The instructions weren't very intuitive and the top roof panels were labeled incorrectly but I was still able to get it assembled with trial and error in probably 15 minutes total. Maybe my fault, but one thing to keep in mind is that the 23" H dimension does not refer to H=Height, but instead is the dimension of the base footprint. The height is ~18". I assumed that H equaled height and that the base footprint was width and depth so the greenhouse did not fit inside my raised garden like I had hoped and I had to use screws to fix it to the garden instead of using the provided stakes..

My wife has been wanting a greenhouse for awhile now. I ordered the 9.5 x 14 foot one for the backyard. Delivery was fast and it comes in three big boxes. One box came on one day and the other two came the following day. Assembly is easier if you lay out all the parts. One of the boxes has all of the plastic sheeting for the walls and ceiling. The other two contain all the metal parts for the base, frame and hardware. Tools are included for assembly, but I highly recommend a power drilldriver to speed up assembly. Assemble was time consuming, but not not super complex if you follow the directions and don’t try to rush it. There are some parts of the assembly that does require two people. My son helped with constructing the base and the wall and ceiling frames. The rest I did alone over a three day period for 2-3 hours a day. The greenhouse is massive and has plenty of room. I was surprised at how all the pieces fit snug like a glove. I am happy with the quality of the materials and my wife loves her new greenhouse.. Scott. US. Sat Dec 09 2023

It turned out pretty nice for the price. We have a couple of spots that are damaged- one seam was apart and the Velcro strap came off when strapping around the bottom.
