We positioned the frieze board on one side, then removed the scrap to install the other side. First, precut cedar 2×4 blocks to match the spacing of each stud bay. Fasten the blocks to the gable 36 inches from the peak, tip up the next truss, fasten it to the blocks and then add the next blocks.

Double-check the truss layout to verify that the edge of each sheet will land on a truss, then set the sheets in place. We fastened a long board to the center cripple toward the top of the gable to use as a brace, pushed the gable upright and then braced it plumb. With it in place, we added a second top plate to the side walls where we’ll rest the trusses. Second, the collar ties are cut from 2-by material and fit between the two rafters. Third, we added cripples to match the layout of the wall they’ll be sitting on.

Built from plastic, plexiglass or glass, a basic greenhouse turns sunlight into heat while protecting plants from pests, disease and weather extremes. In a greenhouse, the gardener creates the ideal environment for their plants. They can adjust the temperature, control humidity, provide shade as needed and experiment with different soils and fertilizers.

We cut the sheets to length, making sure each seam landed on a stud, then used two-inch stainless steel roofing screws to fasten the sheets. Along with the front door, there's a large roof window that you can open or close to control the interior temperature and humidity level. Although no shelves are included with the greenhouse, you could easily add your own shelves if desired. You can also add a small heater if necessary during the coldest winter days. Top the frame with the green high-density polyethylene fabric cover, and you are ready to go.

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. The cover is made from polyethylene plastic, which helps control temperature and humidity, although not as effectively as polycarbonate. Still, we appreciate the two side windows for extra ventilation, as well as the large double-zippered front door. Plus, the greenhouse comes with 12 shelf panels that can be attached down the full length of the sides to hold pots and baskets. Maximize your herb, vegetable, or flower gardening with this attractive walk-in greenhouse from Palram.
Of those gases, known as greenhouse gases, water vapour has the largest effect. Unlike conventional rectangular greenhouses, our octagon-shaped structure not only enhances visual appeal but also maximizes sunlight exposure from various angles, promoting optimal plant growth. So, whether you want to grow the odd palm or feed your family with fresh veggies from the garden year-round, here’s everything you need to know about how to build a greenhouse, even if you’re not royalty.
There’s even a 60-acre greenhouse in Kentucky that produces millions of tomatoes a year! But for homeowners, it typically involves installing a greenhouse in your garden area. If you’re an enthusiastic home gardener curious about greenhouse gardening, read on — we’ve got you covered. Cheap but effective, the underground greenhouse is a great way for growers to produce food year-round in colder climates.
A greenhouse is heated partly by the rays of the Sun and partly by artificial means, such as circulating steam, hot water, or hot air. Greenhouses can range in size from small sheds to industrial-sized buildings and enormous glasshouses. The smallest example is a miniature greenhouse known as a cold frame, typically used at home, whereas large commercial greenhouses are high tech production facilities for vegetables, flowers or fruits.
A mini greenhouse can protect your herbs and other small, potted plants. By 1663, Louis XIV had the Palace of Versailles orangery to house the citrus trees from Italy, Spain, and Portugal. Eventually, the two-sided gallery—protected from the elements by stone walls and south-facing double windows—stretched about 165 yards long, with 42-foot-hight vaulted ceilings.
Be sure to build the frame to the exact span of the walls, then draw a line up from the center point to locate the ridge miter. Up from the corner on each side of the template at a 45-degree angle. With this setup, we could accurately mark and make all the necessary cuts before assembly. Make a template to accurately cut the rafters and assemble the trusses to ensure they’re all identical. We built a simple 2×4 frame on a pair of sawhorses and fastened a piece of sheathing to the top. You could even set it up on a balcony to create a sunroom or growing area.

You can also increase the wind resistance and durability of the greenhouse by assembling it over a concrete or brick foundation and bolting it down. Whether you are new to gardening or have been gardening for years, our top pick from Veikous will serve you well. We love that it's large enough to hold plenty of plants but not overwhelming.
The modern greenhouse is usually a glass- or plastic-enclosed framed structure that is used for the production of fruits, vegetables, flowers, and any other plants that require special conditions of temperature. The basic structural forms are the span-type greenhouse, which has a double-sloped, or A-shaped, roof, and the lean-to greenhouse, which has only one roof slope and leans against the side of a building. Two or more span-type greenhouses are sometimes joined side by side so that they have fewer external walls, and heating costs are consequently less. A greenhouse has a large expanse of glazing on its sides and roof so that the plants are exposed to natural light for much of the day. Glass has been the traditional glazing material, but plastic films, such as polyethylene or polyvinyl, and fibreglass are also common. The framing of the structure is made of aluminum, galvanized steel, or such woods as redwood, cedar, or cypress.
In the UK and other Northern European countries a pane of horticultural glass referred to as "Dutch Light" was historically used as a standard unit of construction, having dimensions of 28¾″ x 56″ (approx. 730 mm x 1422 mm). This size gives a larger glazed area when compared with using smaller panes such as the 600 mm width typically used in modern domestic designs which then require more supporting framework for a given overall greenhouse size. The warmer temperature in a greenhouse occurs because incident solar radiation passes through the transparent roof and walls and is absorbed by the floor, earth, and contents, which become warmer. As the structure is not open to the atmosphere, the warmed air cannot escape via convection due to the presence of roof and walls, so the temperature inside the greenhouse rises. Without the heating caused by the greenhouse effect, Earth’s average surface temperature would be only about −18 °C (0 °F). On Venus the very high concentration of carbon dioxide in the atmosphere causes an extreme greenhouse effect resulting in surface temperatures as high as 450 °C (840 °F).
