Features

  • Heavy Duty Greenhouse for Outside: Keeping a greenhouse outside can help you keep your shovel in the soil year-round. Whether you want to nurse seedlings or grow tropical plants, our polycarbonate greenhouse kit offers plants protection from cold, wind, rain, and wild animals.
  • Polycarbonate Greenhouse: Elevating humidity with superior insulation, transparent polycarbonate panels make our greenhouse ready for outside conditions. They allow in nourishing sunlight while still blocking scorching UV.
  • Rooftop Vent: Let excess heat and humidity escape slowly outside so you can reach peak grow conditions. Keep control of the air inside by making use of the hinged vent found on the top of your backyard greenhouse.
  • Sliding Door: A sliding door gives you room to walk planters, tools, and other equipment into your outdoor greenhouse with ease. Open it to vent away old air, or seal it swiftly to maintain a heavy-duty outside barrier.
  • Heavy Duty Against Water: Powder-coated aluminum gives our outside greenhouse a water-safe build that's easier to assemble. A galvanized steel base reinforces the structure for more strength overall. Rain gutters aid in collecting natural rainwater. Note: We recommend placing it against a wall and out of the wind.

  • Awesome greenhouse purchase!
Color: Dark Green Size: 74.75" x 99.25" x 79.25"
The media could not be loaded. Love this greenhouse! (Now that it’s built) Building it took a bit, a few choice words, some busts of anger, and a couple snacks to easy the process along 😂 But overall now that’s its build it’s amazing! I was worried about other reviews I saw about the panels blowing away. I live in a SUPER windy area, we haven’t had a single issue. None have even tried to blow away. We did do the extra step with the screws through the panels and I think that’s what sealed the deal. Plenty of space for what I needed. It’s very sturdy. I added fans to the little peep window up top and a stand fan by the door. We installed a misting system all around as well. We also added a shade cover on the east side for the hot morning sun, it blocks 40% light and that has helped so much. I love this cute greenhouse! ... show more

  • Faulty product- Brittle Polycarbonate
Color: Gray Size: 74.75" x 75.5" x 79.25"
This Greenhouse was purchased 1yr and 5 months ago. It took us 3 months to finally put it together. We were happy with it for the most part until today. I looked close at the polycarbonate paneling on the roof and it has holes in it where it meets the metal bracket. This is the only place where there are holes and the material is very brittle. I touched it and the polycarbonate fell apart. ... show more

  • Nice greenhouse...comes in 3 boxes!!
Color: Gray Size: 74.75" x 122.75" x 79.25"
This is a good greenhouse for this price point Although it says heavy duty, it seemed a little shaky putting together. Once you get it all together, its much better. Unless you live in an area with NO wind, you need to anchor it. We used 4x4 with extra anchors at each corner. We are still in the process of caulking to make it even better. That is a time consuming task! The polycarbonate panels are thin, I was surprised, as I thought they would be sturdier, so I don't know how this will hold up with snow next winter. I have a feeling I'm going to be scooping snow off the greenhouse every time it snows. The window panels are very loose, they kind of slide back and forth about 1/4 inch, and we don't know if this was supposed to happen or not. Putting it together...nothing like a picture book instruction manual to get the blood flowing! Some of the pictures are very tiny and required a magnifying glass to see the angles and how the ends went together. So their instructions could definitely be much better. Listen and follow the instructions! Don't tighten everything, you'll just end up loosening and retightening those screws later after adding more sections connecting those screws that show up later in the instructions! Also, there is protective covering on each side of the panels. One is white and one is clear. Something we missed...the white side cover on the panels needs to be facing out on the greenhouse. We just peeled and put them up and now have no idea what side was what. One side has the protective UV covering... But that being said, if you take your time and work together, read ahead a bit in the "instruction book" and get an idea of what is what, but don't skip any steps! Once it started coming together it was wobbly, and Im glad I read the reviews so I was prepared for this. But we did keep saying, this can't be right it's too wobbly. Panels in make it much sturdier and by the time the roof goes on, you'll be thinking, now it's getting better. There are gaps, especially in the door and the windows, we will have to get some weather stripping or something where it cannot be caulked. it took us almost 2 days working about 6hrs each day. It's a good size, (10x6), perfect for what I needed. It was about 95 degrees in there yesterday with our outside temp at 69, so it does get hot quickly, but it wasn't really retaining the heat by the time it was getting chilly outside, maybe that will change once we finish caulking. I had the windows open and a fan running to keep the air circulating. Can't wait to be able to keep my plants in there when its warm enough at night! The seller is very easy to work with! They even answer the phone when you call! The greenhouse comes in 3 boxes and FEDEX lost one. Aesom was very quick about getting a replacement sent out, but then FEDEX pulled their heads out and we received the box. Aesom has sent messages to make sure everything is here and for that they get 5 stars!! ... show more

  • Value exceeds price, customer service is EXCELLENT
Color: Dark Green Size: 74.75" x 75.5" x 79.25"
Packaging (B+): Came in 2 boxes; one for the frame, one for the plastic panes. Zero damage to the panes (great packing). Very minor bending here and there to a handful of the dozens of frame pieces (corners and such), but they are aluminum, so easily bent back. Assembly (B-not easy, not hard): I was able to assemble this 99% by myself over several hours, although the estimate in the manual contemplates 2-3 people. I had to puzzle out some of the instructions, but overall they were pretty good. Caveat: I am really good at assembling things. If you are not, you should expect to need help from someone who is. There are A LOT of parts. Quality (A+ for value): Machining was excellent. Frame is sturdy. I want to say upfront that for the price this is a tremendous value. That said, I would not expect panels to survive a harsh winter in the Northeast U.S. (they are fairly flimsy), and will take precautions. I will either cut outdoor plywood to cover it or will put it inside a tent storage unit I have. It is easily picked up an moved by two people. Incidentally, because it is so light, I am going to anchor it to a 24" steel spike driven into the ground at each corner, just to be safe. The spikes are available from a big box home center in the concrete rebar section and only cost around $10 for 4. Just one more note on value: I may replace all the panels with Lucite in a couple of years. I think this will cost about as much as the unit did originally, but in my opinion the frame is of high enough quality that even if this causes the cost all-in to double, this is still a great value. Customer service (A+++): A small bag of 6 screws was missing from my unit. I contacted customer service and they responded promptly. Then, they went above and beyond the call of duty to resolve the problem. ... show more
