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
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 on the commercial Everest. All models rated to 65 mph 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.

"We're in our 70s and I just wish we had done this earlier! The old hoop house we had was not insulated and needed new plastic every year. This green house is so sturdy and needs so little to be done other than visit to tend my winter greens. Will be starting earlier this year outside in the greenhouse instead of the dark basement! YAY!"
"We live in a very windy and snowy climate in the winter. This greenhouse does not make a noise, does not shift and can hold plenty of snow weight. This is a much better purchase than anything that you will find in big box stores like Home Depot."
"Everyone at Planta Greenhouses was very kind and helpful. I lost my old greenhouse to the December storm of 2020, and couldn't find a similar size greenhouse until I found the Planta Greenhouse company. It was just what I was looking for at half the cost of anything else I could find. They let me pay 1/3rd down for my 10x32' model, and then two more installments over the winter. When spring arrived, they contacted me as to the shipping date, and everything came in great condition."
"I'm very happy with the quality of it and I can't wait to grow more produce and extend our growing seasons."
"It is a beautiful extension of my farm and I can’t wait to utilize it in many ways.
For example I live in Virginia but I would love to grow tropical bananas, avocados and strawberries 🍓! ...
