3x6 Garden Cold Frame

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

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.

Only reason for two stars is that one of the large panels came in cracked and I was sent a replacement one with a crack in it as well. Huge bummer as she is not a cheap cabinet.. Madilynn. Holly, MI. Wed Nov 19 2025

Its very cute. Im glad I read the reviews to know what to expect with having to drill holes yourself. It was easy and no, the doors dont line up but it serves its purpose. I think it is highly overpriced though!!!. Kim. Pittsburgh. Fri Sep 25 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.. Michael. Watertown, WI. Thu Apr 17 2025

Ideal to nurture seedlings outdoors and protect plants from the elements. Hinge to prop the roof open while working in the frame. Polycarbonate roof. Treated for protection against wood rot and decay. Treat annually to prolong appearance and strength. 39.4"W x 23.6"D x 15.4"H, 22 Lbs.

Complete garbage. Wood is thin & cracks as soon as you try assembling. I followed the very basic, pictorial directions and used all included hardware and before the frame was even assembled, the wood on all sides cracked and split where the screws were put in and the whole thing fell apart. I considered salvaging the wood and trying to just nail it together but it’s not worth putting more time into this. Horrible product. 0/5 stars.. Rob. Highland, MD. Mon Jun 03 2024

Not great quality. The frame itself folds up so it is easy to set up but doesn’t sit square or firm so there are large gaps between the top lifting pieces. Fairly rickety over all and way over priced.. Katelynne. US. Mon Mar 21 2022
