Ate from our greenhouse all summer
We purchased our greenhouse in spring 2025 and ate from it all summer. It kept our growing season strong, was sturdy, and arrived on time with clear instructions. Very happy with the whole experience.
Heaven in Alaska!
We live in interior Alaska, where growing can be almost impossible without a greenhouse. Ours kept plants warm, handled harsh weather, and helped us grow peppers, cucumbers, tomatoes, and more. We're already considering buying another.
My perfect greenhouse
Your Greenhouses answered all my questions quickly. The greenhouse was easy for two people to build, and I'm ready to start my gardening journey. It's sturdy, beautiful, and I highly recommend it.
Stronger than I expected
We wanted a greenhouse that could handle windy days and still look good in the yard. This one feels solid, was simple to put together, and has already made a huge difference for our tomatoes and herbs.

Built for bad weather
World's Most Popular Polycarbonate Greenhouse
Best For: All-round family gardens & heavy-weather climatesCurved double-wall polycarbonate greenhouse rated for 65 mph wind and 3 ft of snow, in lengths from 13 ft to 45 ft.
65 mph wind, 3 ft snow load
Tested to handle 65 mph winds and snow loads up to 32 psf - roughly 3 ft of fresh snow on the roof. Built for gardens that see real weather.
1/4" double-wall polycarbonate
Two walls of polycarbonate with an insulating air gap between them. The gap holds heat overnight and protects plants from frost, adding weeks on both ends of the season.
6 ft 6 in interior height with 9.84 ft width
Widest footprint in the range, with curved sidewalls that round off the corners wind and snow normally catch. Comfortable working height through the middle and more floor space for beds and shelving than either of the other two models.
10-Year Warranty
Most polycarbonate greenhouses in this price range come with 1–2 years on the frame and no panel warranty at all. Buy this one and you're not replacing it in three years.
What's included
1 front door, 1 back window for natural ventilation.
Pre-Order Today: Save up to $4,000 vs Summer Sale pricing + free delivery. Only limited stock will be offered at this price.
Classic Arch Greenhouse
Best For: Tall crops, premium look, heavy snowA taller arched greenhouse with full standing room and a roof shape that sheds snow on its own.
65 mph wind, 3 ft snow load
Rated for 65 mph winds and snow loads up to 49 psf - about 3 ft on the roof. The arch geometry means snow, hail, and rain slide off instead of sitting and adding weight.
1/4" double-wall polycarbonate
Two walls of polycarbonate with an insulating air gap between them. The gap holds heat overnight and protects plants from frost, adding weeks on both ends of the season.
Full arch shape, ground to ridge
One continuous curve from one side to the other. No flat surfaces for snow to sit on, no corners for wind to catch - the geometry does the weather-handling work.
7 ft 10 in interior height with 9.84 ft width
Full standing room down the center, widest footprint in the range, and enough overhead clearance for trellised tomatoes, climbing cucumbers, and indeterminate vines.
10-year frame warranty, 5-year panel warranty
Most polycarbonate greenhouses at this price come with 1-2 years on the frame and nothing on the panels. Buy this one and you're not replacing it in three years.

1 front door, 1 back window for natural ventilation.
Pre-Order Today: Save up to $2,800 vs Summer Sale pricing + free delivery. Only limited stock will be offered at this price.

65 mph wind, 3 ft snow load
Rated for 65 mph winds and snow loads up to 32 psf. The peaked roof pitches snow off both sides instead of letting it pile in the middle.
1/4" double-wall polycarbonate
Two walls of polycarbonate with an insulating air gap between them. The gap holds heat overnight and protects plants from frost, adding weeks on both ends of the season.
8 ft interior height with 8.2 ft width
Tallest ceiling in the range, with straight vertical sidewalls right up to the roof. Run tall trellises, hang baskets from the ridge, and use the full width for shelving without losing space to a curve.
10-year frame warranty, 5-year panel warranty
Most polycarbonate greenhouses at this price ship with 1-2 years on the frame and nothing on the panels. Buy this one and you're not replacing it in three years.

what customers say
Cucumbers and tomatoes went crazy
We built it with our grandkids most of the time, so it took us six weeks to complete. The plants that were started and put inside went crazy. They loved the atmosphere and produced huge amounts of cucumbers and tomatoes. Bruno's always available to answer questions.
Danny Rankin
Built it solo at 68
We got our greenhouse last spring. I am sixty eight years old, and other than holding and starting screws by my wife, I built it by myself. Easy, but time consuming. It's complete and we love it.
Russell Carson
Passed city code in the Midwest
It's the only one that would meet the requirements for the city, meeting 65 mile an hour wind loads and 3 feet of snow! Perfect for the Midwest! It was easy to assemble as well!
