Garden greenhouse 12x7x7

KattApril 12, 2025✓ Verified purchase

Not bad for the price! It's not that strong and sturdy but it's worth the money for a small simple greenhouse. It's just what I needed for my garden area and my herbs. The wind almost took it before I finished setting it up. I attached it to my garden fence and then placed blocks around the outside bottom. I'm glad I didn't get a bigger size. I'm happy with this item and would buy it again. Read more

THE ONE THEY SENT ME IS TERRIBLE

Olivia TapeltApril 29, 2023✓ Verified purchase

The description said "dual Zippered screen Doors" this one has 2 zippered doors, but one screen door. The zippers on the doors do Not go all the way down to the floor and leave too much space for critters and bugs, and one does not zip very well. The only sturdy, durable thing about this greenhouse are the screws and wing nuts. They are Awesome. But you cannot tighten them because it will flatten the frame pieces which will no doubt bend with any wind. And there are NO ties to fasten the cover on the lower part of the frame nor ties to fasten top of the door ends arch to the frame on either end. The ties that are there are so short you cannot tie a bow for easy take down and can barely tie a knot. It is missing one end cap which is necessary to keep from puncturing cover. One of the frame pieces had dents and one had deformed end. The fabric on the white zippers was dirty which makes me wonder if I got someone's return for a cover. I have Never been SO disappointed in a purchase as I am with this one! Actually, I am MAD because I need this Now. I am in Minnesota and my seedlings are ready to be transplanted and moved to a greenhouse NOW. And I did not get what was advertised!!! The one they sent me is TERRIBLE. Their sewing job left long strings on every window. This is also maddening because I have to take it ALL APART to send it back and make a 26 mile trip to return it. I do NOT recommend this item. I was going on the majority of good reviews. I don't see how....they came up with their reviews. Or why did I end up with the bad greenhouse. Read more

Easy set up, good ventilation and pretty sturdy.

DerekDecember 29, 2025✓ Verified purchase

The media could not be loaded. So far the Green house is surprisingly sturdy. I did upgrade the ground stakes to a longer and thinker version but with the tie downs and stakes it’s holding up very well. We have been having some 30 mph wind gust and it’s doing very well. The windows are nice and provide good ventilation. The draw strings used to keep the door and windows rolled up are a lil shorter than I’d like but they work. I’m using it for winterization of my turtle pond. Temps here can get in the 20s at night and even with a pond heater didn’t want the lil guys to freeze. I will try and remember to add further notes once the winter season is over and see how it held up but so far worth the money. Read more

Affordable outdoor housing for your plant babies

Jeanine LingoDecember 13, 2025✓ Verified purchase

Solid and good value.

J.D.November 22, 2025✓ Verified purchase

These aren't exactly fancy greenhouses, but they are pretty tough and good quality for the price. I got them to keep my ducks in during the Avian flu outbreak to keep them safe. I was able to assemble them myself easily, and they've been through a few big storms and they're still standing. Good product. Read more

mine has been through 60 mph winds

Spacious, convenient but need to be steadied

TarkporAugust 19, 2025✓ Verified purchase

DON'T BUY!!! Assembly is difficult, quality is cheap and will not stand even the little wind. Absolutely need two persons to construct. It takes a bit of time to figure it out but it looks good in the end. I built it in summer so still awaiting winter to see if it would stay up. I used rocks to secure it tough. Dont assemble without the gloves provided in kit. It broke down due the the wind at the end of summer. Steel quality is poor, sun will not get to your plants. Completely a waste of time and money. Do Not Buy!!! Read more

Not as good as its competitor . . .

Mom of Great KidsDecember 13, 2024✓ Verified purchase

We use portable greenhouses to protect our lemon trees in the Winter. You set them up, cover the trees with the option to remove them daily if you need to so that the trees can get sun during the day and recover them for protection from the freezing weather at night. A few years ago, we used a competitor's brand. This year, my husband suggested this brand for its green material being more "organic" than the white/clear material used by its counterpart. Plus - they were on sale $20 less for each one (we bought 2). A few observations: 1. This greenhouse only has 1 door vs. 2 on the competitors brand. While that might not be a big deal for some, IF you use a portable heat lamp in conjunction with the greenhouse to protect plants/trees at night, during the day when that heat lamp is off and the sun is creating heat inside the greenhouse, you want ventilation. While these have windows that you can prop open - those windows are small and a 2nd door on the opposite side definitely would make a difference. (See photo.) 2. The green material covering is less thick. 3. The metal/steel material that makes up the skeleton of the structure is DEFINITELY less strong/thick. They bend very easily, which, when you are using this as a portable structure isn't ideal. (See photos.) 4. The cloth "ties" that you use to tie up the window material and which you use to tie the material to the skeleton are VERY short. If you have medium to large hands - or your hands aren't very nimble, you will have trouble tying these ties into a sturdy bow. (We don't do knots because those knots would take forever to undo.) Even 1" more of material would make a significant difference. (See photo.) 5. No stakes are provided with this item. That didn't matter to us though because we weigh each side down with old Trex boards. This item (as well as its competitors greenhouse) have a "lip" at the bottom which allows you to place stones, boards, etc. on it to weigh it down. (See photo.) We are keeping these for this year - hopefully they will last through the next few months, but I have already purchased more of the competitor brand for next year. An extra $20 is worth of cost of the added features. Live and learn. Read more
