Green house

A greenhouse is the best way to extend your growing season or grow exotic plants that otherwise wouldn’t thrive in the climate you live in. But their various types and uses vary, points out Veronica Lorson Fowler, a master gardener based in Ames, Iowa, and author of a number of gardening books. "A hoop-type greenhouse/row cover that is temporary might be fine for those gardeners who simply want an early start on cool-season vegetables, like lettuces and other greens," she says. "A serious orchid collector will want a sturdy wood- or metal-framed greenhouse with excellent climate-control features, like venting systems, fans, and depending on the climate, a heating system with an alarm." To find the best greenhouses for specific needs and uses, we researched dozens of options in all sizes, ranking them based on material, structural stability, and overall value. What We Don't Like • Not very stylish Our pick for the best overall greenhouse is the Home-Complete Walk-In Greenhouse. This budget-friendly greenhouse has a sturdy steel frame and a durable PVC plastic cover that controls the greenhouse temperature and lighting, keeps out pests, and encourages plants to thrive all year long. One of the best features of this top-rated greenhouse is its size and light weight (20 pounds). We also like that it can be used both indoors and outside. You'll find it small enough for most outdoor spaces such as patios, but large enough to walk comfortably into to manage your plants and mov...

It provides an ideal environment to magnify or reduce sunlight as needed, control Transparent roofing and insulating walls, controlled ventilation and easy access to water make all this possible. Not all greenhouses amplify light. Some provide shade to protect plants that can’t tolerate full sun and high temperatures. And some incorporate sunny and shady zones so a diverse ecosystem can flourish. Types of Greenhouse Materials Although there’s no reason a greenhouse can’t have a structure as strong as a house (and some do), most have rudimentary frames made of metal pipe, plastic pipe or wood. • Plastic piping is the least expensive material, but lacks the rigidity needed for a large structure. Here are a few tips for buying • Wood is a good thermal insulator, important in cold climates. • Metal piping (aluminum or steel) is long-lasting and durable, but it isn’t a good insulator. Especially aluminum. Large greenhouses often have well-insulated glass walls and roofs. But clear polycarbonate, acrylic and fiberglass also work, especially for smaller structures. • Glass is the traditional greenhouse material. It’s expensive, difficult to install and can crack. But it insulates well, looks best and transmits light the best. Browse our top picks for • Acrylic is also expensive, but it’s long-lasting and, unlike glass, can be bent and molded (to a degr...

• Extend the growing season (maybe even year-round depending on your location). • Start seeds early and inside. • Expand your options for a wider variety of vegetables and flowers. • Stop worrying about the weather. • Protect plants from bugs, birds or pesky nibbling rabbits, squirrels and other wildlife. • Maintain correct and consistent moisture and temperature levels for bigger, healthier, and faster growing plants. • Use built-in potting benches to work with ease and comfort. No aching back or kneeling in the dirt. (*potting bench optional) • Store containers, tools, and gardening supplies in one convenient place.
