It’s always growing season inside backyard greenhouses.
Quite simply, that’s the appeal of a backyard greenhouse– or even a larger-scale greenhouse on your acreage property. Even when there’s snow on the ground and the cold wind is howling, it’s always summer in the greenhouse. The controlled climate inside a greenhouse makes it possible to grow ornamental plants and edible fruits and vegetables all year long.
According to Tammy Wylie of Advance Greenhouses, you can enjoy the benefits of having your own greenhouse without being a professional grower. “Greenhouses enable you to enjoy growing plants all year long, and that’s the best way to take your gardening to the next level,” she said.
Many avid gardeners and property owners have installed a greenhouse to grow their favorite plants—especially homegrown fruits and vegetables—throughout the year. That’s because an impressive variety of greenhouse styles, sizes and price points is available. Some lightweight greenhouses can even be moved from site to site. Some kits can be built with permanent foundations and foundation walls. Plus, professional-quality greenhouses can be constructed onsite.
The editors at Home, Garden and Homestead have reviewed the attributes of dozens of available backyard greenhouses. Here’s an assortment of greenhouses that can make year-round growing a reality on your property.

Backyard greenhouses with Gothic Arch performance
If you’re looking for a nice-sized backyard greenhouse with style, or a larger greenhouse for a larger property, consider a Gothic Arch Greenhouse. Why? Well, for starters, a Gothic Arch is one of the strongest architectural shapes known to man.
The heart of a Gothic Arch Greenhouse is the sturdy, energy-efficient arch made of Bald Cypress wood. The hand-crafted structural arches are always at an ideal angle toward the sun. Because of the high profile of the ridge, a Gothic Arch Greenhouse is perfect for growing taller plants such as tomatoes, cucumbers and many tropical trees. In addition, the Gothic Arch design encourages condensation run-off inside the greenhouse, and the design also prevents snow accumulation on the roof.
A backyard greenhouse or homestead greenhouse from Gothic Arch Greenhouses comes with three greenhouse covering options: corrugated polycarbonate, 8 mm twin-wall polycarbonate, and 8 mm triple-wall polycarbonate. Greenhouses are available in five widths—8 feet, 12 feet, 14 feet, 18 feet and 22 feet in four-foot increments in length. Install the greenhouse directly on the ground, or place the structure on a foundation wall to raise the height of the roof. Prices start at about $5,200. Check the sizes and pricing options here.

Polycarbonate sheets for greenhouses
Backyard greenhouses are also available as kits. Many property owners buy greenhouse kits in standard sizes. But others choose to build custom greenhouses to fit their specific size and shape requirements.
Polycarbonate sheets from Advance Greenhouses make it possible to build a high-quality, cost-effective greenhouse to your own specifications. One reason polycarbonate glazing is a popular alternative to glass is because it offers higher R-ratings for insulation. Plus, polycarbonate offers multi-wall options for strength and additional options including specialty sheets and anti-fog coating.
The polycarbonate sheets available from Advance Greenhouses come in five thicknesses (6mm twin wall, 8mm twin wall, 10mm twin wall or triple wall, 16mm triple wall or quintuple wall, and 25mm triple wall). All multi-wall sheets have at least a 10-year warranty against hail damage and change in light transmission. Also available are Lexan, Gallina and Polygal polycarbonate sheets that offer 100% light diffusion for happy and healthy plants. A free Greenhouse Planning and Building Guide is available from Advance Greenhouses.
