Backyard models are rated to 75 psf (360 kg/m²), commercial models to 98 psf (480 kg/m²) — maintenance-free through winter.
Heavy Duty greenhouse construction that resists winds up to 65 mph (100 km/h)
Every Planta greenhouse uses a heavy-duty galvanized steel frame with 6 mm or 10 mm twin-wall polycarbonate panels — structural materials, not the aluminum-and-film construction used in big-box kits.
Every frame carries a published snow-load rating: 55 PSF on Sigma Gen III, 75 PSF on Sungrow — the strongest backyard model — and 98 PSF (480 kg/m²) on the commercial Everest. All models rated to 65 mph (100 km/h) winds.
Planta's twin-wall polycarbonate blocks 100% of UV radiation while transmitting the light plants need, protecting both your crop and the panels themselves through years of direct sun.
Most Planta kits accept extension sections, so a 10' × 20' backyard greenhouse can grow past 100 feet later. Extensions bolt onto the frame you already own.
Galvanized steel resists rust and polycarbonate needs no sealing, painting, or re-glazing. Most owners wash the panels once or twice a year and do nothing else.
Planta's team helps with sizing, foundations, and assembly — before and after the sale. Orders process in 2–4 business days and reach most US addresses in 1–2 weeks.
A Planta greenhouse extends the growing season at both ends — starting seedlings while the ground outside is still frozen, and carrying greens, herbs and root crops well past first frost. In Zone 5, that's roughly 6 additional weeks of harvest a year. Twin-wall polycarbonate holds heat better than glass, so most growers get 3- or 4-season use without adding a heater.
"This was my second greenhouse. I have grown tomatoes, cucumbers, beans, peppers and zucchini. The greenhouse has given an additional two weeks of growing time in the spring and Fall. Even without heating. I found Planta Greenhouses to be very professional to deal with.
"I love gardening, and the purchase of the Planta Greenhouse was just the thing I needed for my garden. The first year using it, I figured was a learning curve, but so far so good! I've attached some pictures I took of my greenhouse this past summer...
"We just love our greenhouse. Didn’t know it could be that strong lol! Actually grew cantaloup, watermelon, celery, peppers, tomatoes and cucumbers. Last summer was our first summer with the greenhouse and its the best! Cant wait for this summer! 😃 Actually spinach was totally amazing in there!"
"Its a really sturdy and solid steel structure (weight around 400 lbs. Its like a mini house. Since I installed it 2 years ago, I did not have to clean the snow off it or move it or take it apart. Its perfect if you get a lot of snow or wind in your area."
I just wanted to says how impressed I am with your product. I bought one a year ago April. I live in Stevensville Fort Erie and we had the worst wind for almost 24 hours, gusts up to 120km and my greenhouse survived. Keep making this great product.
