Features

  • Upgraded Roof Vent - Our greenhouse for outdoors compared with the 4-position manual adjustable, the upgraded vent is a pole-less mode with pulleys, which can meet your needs and adjust to a suitable angle. You can easily regulate the airflow by rotating or fixing the buttons tightly to ensure your plants receive fresh air. You can mount the vent in any panel and customize its place during assembly.
  • Powder-Coated Aluminum Frame - The deep gray powder-coated aluminum frame has rust resistance, dirt resistance, and long-lasting durability. The powder-coated aluminum frame is stable and will not be easily blown down by the wind. It is also recommended that you use tie-down kits to improve the wind resistance of the green house. It can withstand harsh weather conditions and provide long-lasting protection.
  • 4mm Twin-Wall Polycarbonate - Our greenhouses are equipped with 4mm double-layer polycarbonate panels, offering excellent insulation and enhanced sunlight refraction to achieve the best conditions for plant growth. The panel has strong flexibility and weather resistance and is not easy to be damaged and aged.
  • Available All Year Round - Our large greenhouse using a sliding panel assembly system, the sealing performance is good and reduces the time spent on installation. Including a metal handle and a lockable door, ensure convenience and security for you. With our greenhouse for outside, you can enjoy gardening all year round, protecting your plants and providing them with the ideal conditions for healthy growth.

My wife loves the greenhouse!! starts plant early

  • Affordable and good quality for price
Size: 6x8 FT
The media could not be loaded. Delivered within a week in two separate boxes, both of which I could move myself. Was overwhelmed by the amount of parts and big book of assembly instructions initially but it was step by step. I laid everything out in numerical order and it simplified the process greatly. A few parts didn’t have the stickers but I was able to identify the number from the pieces list in the front of the manual. HIGHLY recommend using a drill with the bit that fits all the bolts instead of the little Allen wrench sent with it. I built it on a 4” by 4” base which added the perfect amount of height to the doorway on my 6’ by 8’. It is very lightweight and will need something with weight to hold it down if it gets windy. Also added some snap in flooring since it is on concrete. Planning to seal it with caulking soon and then add shelves. Took me a few hrs to build on my own, would’ve been easier with two people. (Also pay close attention to the slope when putting in the center end wall posts- I had them backwards and didn’t know until I went to put the roof on and couldn’t get the frame to align- then had to take the whole back wall apart and flip the posts around to align with a downward slope. Seems like common sense- but it wasn’t on my mind) It was in the 40s today and I was in and out of it and the temp inside was already mid 60s without having caulked the window panes. Love the warmth. Decent quality for the price; rather frustrating to build. Would buy it again in a larger size. ... show more

  • Displeased in Tennessee
Size: 6x12 FT
The greenhouse was assembled according to the printed instructions and the page by page graphic illustrations provided. The end panels went together smoothly. When it came time to assemble the sides of the greenhouse, the polycarbonate panels labeled Panel A were too long. Moving onto the roof of the greenhouse, the panels labeled Panel B and L were too short. The seller responded that their team said the panels were correct. Not good! ... show more

  • Great for the price
Size: 6x8 FT
Great little greenhouse wasn't to complicated and easy enough to assemble by myself I do recommend anchors fully assembled it is a very light structure and high winds would definitely move

  • More work and cost then just buying the green house and putting it together.
Size: 6x12 FT
Over all happy with it, however, keeo in mind a few things. The price you pay for the green house isnt the total price you will spend on it. 1: it will need a base built that it can be attached or anchored too. Its very light and the wind can easily move it once erected. ( made a 2x6 frame on 4x4 skids and decked with plywood.) 2: you have to seal each panel with silicone, otherwise the first wind you get your panels will blow away. I sealed both inside and outside of my panels with clear silicone and havent had an issue since. (It took 7 tubes of silicone to completely seal the 6x12 i bought.) 3: the hinging and leavers in the vents are cheap and i recomend replacing imediately. 4: the door after being sealed with silicone is sturdy, however, it lacks a hold open feature and like to slam in the wind. I suggest using some sort of hold open. (I used a bungge cord.) 5: even after sealing, and mounting to base it is still essential to wind brace the whole structure. I used screw in anchors, cabkes and turn buckles. The positives if after you do all of the above its a solid unit, looks good, and does what a green house should. After the cost of green house and doing all the extras to make it wind and weather proof my final out of pockets expenses were right around 1,000 dollars. ... show more

  • Overall, very pleased.
Size: 6x10 FT
Had an issue with a missing panel. Seller responded immediately and went above and beyond to get us the missing part. 5 stars for customer service. 4 stars because the allen wrench provided was hard to use and stripped screws a lot. We had to get our own to finish. Fortunately extra screws were provided so no issues being short. Gets super warm inside so we're excited to start our garden. We did silicone all seams as we live in a windy area. Overall, very pleased. ... show more
