  • One smart gal can build it alone in three days after work.
Style: 15ft-Greenhouse Color: Green
With a few little tweaks, this greenhouse is dynamite! 1. The frame was pretty easy to put together. Similar parts are bundled together, and each part has a label sticker on it. It was a little awkward assembling it by myself, but I managed to build the frame in about three hours after work. It is a easier to use a wrench instead of the small tool that is provided. 2. The frame does need a little reinforcement. Otherwise, you are relying on the cover too much to hold it in shape. 3. I drove steel pipes into the ground at each corner, just inside the corner, and wired the frame to them. If you put the stake outside the corner, it will interfere with the cover. This was the first major step that really held the frame squarely to the ground. This took one more evening after work. 4. The next step was to wire the diagonals. There are only two diagonal pipes on the frame, which is not quite sufficient. The wired diagonals are shown in the second picture. 5. I also wired the diagonals on one end. This limits the greenhouse to one entrance, but significantly strengthens the structure. All told, I used a 100 foot roll of galvanized wire that is rated for holding 75 pounds. The wire cost around 13 dollars. 6. After I stretched the cover over, I used a stronger cord instead of the thin cord that came with the kit. The roll was less than 10 dollars. Also I used cinder blocks that I had around. Also, I put it near an existing fence. 7. So for less than 25 dollars, plus some things that were laying around, this thing can be made super sturdy. After I take the cover off during the hot part of summer, I will also reinforce the top bar and add some vertical supports. With these additions, I am sure that the frame will last for at least 5 or 10 years. 8. For the price, this greenhouse is great. It definitely needs some tweaks, but the whole thing is so inexpensive that is worth it. My intent is to leave the cover on in spring and fall for a season extension. That way, the cover is not damaged by the worst of summer and winter. 9. Right away, I moved in a chair and some shelves and a little mini greenhouse that I had inside. Now I don't need to carry my seedlings in and out of the house each day! 10. The screen zippers are not as durable as the main zippers. Be gentle with them. 11. I am being critical of the weak points, but the poly-carbonate greenhouses that cost several times what this cost have weak points, which are harder to remedy. This thing is a great bargain, if you have just a little skill to make it sturdy. It has tons of space! I love it! ... show more

  • Very nice DIY greenhouse!
Style: 10ft-Greenhouse Color: White
We bought this greenhouse to keep our back porch plants protected from the frost. Fits on the porch nicely. We secured it to the porch so it wouldn’t blow over in our wind gusts by putting three 5 gal paint buckets filled with sand on the metal frame base. No problem with the wind so far. We ended up taping the bottom cover flaps around the bottom of the frame using gorilla tape, normally you would stake it in the ground. Stakes and rope were provided. They even provided two extra bolts and extra other accessories. It took two of us carefully following the instructions to construct it as it’s important to assemble it so that the bolts connect all of the parts at each joint. Screws are locking, so don’t tighten them beyond what you can do by hand until it’s all constructed fully and all pieces correctly joined. That way you can disassemble partly if needed to properly join a piece you might have forgotten. This is particularly important for the upper stage/ level and roof support assembly. They give you 2 Allan wrenches and 2 small open wrenches for the bolts/ nuts. We found that using a pair of locking grip pliers with the Allan wrench worked much better than the open wrench. They even provided 2 pair of work gloves. Instructions are in Chinese English so there are funny phrases like “firstly do this…”. But they are nicely detailed and give a good description. It took us 2 hrs to assemble. It’s very sturdy looking and feeling. Plastic is thick and durable. It’s see through enough to allow ample sunlight in. It also has nice screen windows and doors that can be exposed for air ventilation when needed. So glad we got it. It nicely does the job. ... show more

  • Nice Functional Sturdy Greenhouse
Style: 10ft-Greenhouse Color: Green
This greenhouse held up through some pretty insane wind storms! I live in a place where it’s extremely windy a lot of the time and not once did it blow away, though sometimes it did kind of seem like it might. The zipper on the door broke, so I contacted the company and they sent me a replacement cover. The plastic cover makes a very loud noise when it flaps in the wind so I took the cover off during the winter season when its windiest. It kept my plants out of the scorching sun in the summer and protected them from the high winds. It definitely does get 10-15 degrees warmer inside of the greenhouse. It wasn’t too hard to put together, my boyfriend and I did it in a couple of hours. It’s big enough to stand up inside and stick my hands up a little and I’m 5’6. I will be putting the cover back on and using it again this spring! (-1 star for the zippers being cheaply made and breaking easily, but big thank you to the company for replacing it!) ... show more
