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!

Zippers and Velcro window closures need to be improved, and the edging flap, used to seal the bottom edge of the cover could be longer, for more material to "weigh" it down. Our zipper broke, middle of the winter... ( That zipper underwent 2-4 zips, every day, for 4 months...). I laid a level, 6" gravel bed, mounted the tube frame on top of a 2x4 pressure treated base frame, w/ corner stabilizers (the photo only shows the side rail 2X4s, but the entire tube frame was supported by a 2X4 base) . Then, I attached the tubular frame to the base using metal pipe/conduit (half circle screw-downs). I then drilled holes at each of the 4 ends of the wood frame that I extended, and anchored the entire greenhouse with 3' rebar rods. We intended to keep this greenhouse, and we're relying on it to supply us with food, especially my wife's Asian veggies and herbs, that are difficult to find. We installed it like it was important to us, so we went the extra mile... In the end, we were THRILLED with this greenhouse. Beautiful! Yes, the zipper failed. BUT, I used clear flex tape to realign, and seal the two edges, FROM BOTH SIDES, AND CLOSED IT UP! We started using the zipper on the other side, of the same door, and we had the entire other end of the greenhouse if we had needed it. I never called to complain, I just left a review without giving the kingBird people an opportunity to make it right... WOW, I WAS TAKEN A- BACK when I received an email from them, wanting to know what happened. After explaining the situation, they promptly offered to replace the cover. I couldn't believe it, but, the new cover has been delivered. This greenhouse is worth EVERY PENNY! If you do some extra things, like we did, it will provide you with a GREAT experience. Ours was in a field, and it withstood several wind, rain and snow storms. The wind reached 30-50mph!! Look, if you're expecting an angled aluminum framed, a rigid polycarbonate sheet paneling, and want to pay the $1500-$3000 , go for it... Otherwise, you cannot go wrong with this kingBird greenhouse. Also, the reason I purchased it was because I own the 41' kingbird MOTORHOME cover, and the quality, for the price, impressed me sooo much. Now, having experienced the TOP -NOTCH customer service??? I'm impressed, and that's not something easy to do, for me. Well done, Kingbird. Please, improve the zippers, and YOU'LL hit it outta the park! Customer FOR LIFE!

This greenhouse has been great for 2 years. The frame is still very solid. We anchored it very well when we installed it. The cover has had problems. One of the zippers stopped working after a few months, but I left that side closed, and things were still fine. Now, 2 years later, the Velcro no longer sticks on the windows and there is a rip in the fabric too large to patch. I reached out to the company, Interested in buying a replacement cover, but did not hear back. 2 years is a pretty good run for a product of this price that is outdoors in the elements, I just wish I could purchase a new cover without having to buy an entirely new frame as well.

Setup was easy and arrived 3 days earlier than expected and that saved a bunch of our plants from this ice storm that hit! It held up to some thick ice and snow! We had 3" of ice on it at one point and it held strong!
