A greenhouse with an opening roof is the dream of every summer resident. After all, she is not afraid of overheating when growing plants in the summer, when the puff airing is not enough, as well as snow drifts in the winter.
In this article we will talk about the purpose and advantage of using a greenhouse with opening roof.
Appointment of a greenhouse with opening roof
All greenhouses with an opening roof are usually translucent, and the built-in automatic roof opening system allows airing and opening access to sunlight for plants. The roof in the greenhouses opens as if in a casket, allowing fresh air and heat to penetrate inside the room. Today, new products are on the market, greenhouses of this kind are becoming increasingly popular both in private and in industrial cultivation.
The most important purpose of the greenhouse with opening roof is that in sunny warm weather you will not need to leave the greenhouse closedBecause the weather conditions will be positive for the plants. But in the usual greenhouse in the same weather will be much more heat, that is too hot microclimate than you need to grow plants, which will lead to the death of your crops.
Features of the design of the greenhouse-cabriolet
A prominent representative of the opening designs is greenhouse with sliding roof. Thanks to the convertible top in the greenhouse, good ventilation, even if it suddenly rains and there is a strong wind, the plants will not be damaged. Greenhouses with a removable roof are made of polycarbonate, so they dissipate light quite well and can even withstand hail. The design can be used in the temperature range from -40 ° C to +90 ° C. 
The roof of the convertible greenhouse can be moved down. Sheets of material are made so that they can be effortlessly lifted up or moved, depending on weather conditions. Thanks to the clamps that are provided in greenhouses, the sections themselves do not move down. They fix the sheet in the desired position. When snow falls on a convertible greenhouse in winter, it thereby provides the soil with the necessary heat and moisture to keep the microorganisms in the ground. The locking elements in the greenhouse are designed for a long time, however, if the need arises, they can be replaced or made yourself.
In such a greenhouse also provides vents. Experienced gardeners recommend opening the roof in hot weather, since it will not be enough for a full air flow and airing the vents. Sliding greenhouses are very popular because they are easy to install and do not need to remove snow from the roof in winter.
The advantages of using greenhouses with sliding mechanism
Of the advantages of greenhouses with a sliding mechanism, it is worth noting the sliding roof element. This is one of the most important components of the design, since it performs many functions. For example, he without effort and effort helps to shake off the snow and dirt from its surface. For this purpose, special hinges are used in the roof structure, on which it makes its movement. It takes only a couple of movements, and the roof will be completely cleared. 
In summer, when the sun bakes, the sliding roof creates favorable conditions for growing plants. When the sun's rays penetrate the surface of the greenhouse, all the plants and elements that are under it are heated. In order to avoid overheating, you just need to move the roof, fresh air penetrates under the surface of the greenhouse, and the plants get the sunlight they need.
Thanks to the sliding mechanisms, the roofs of the garden are reliably protected from bad weather and precipitation, so rain, hail or strong wind will not affect your plants, but remain outside the greenhouse.
Did you know? Most manufacturers make sliding greenhouses from polycarbonate, so they are lightweight, durable and inexpensive at the same time.
Popular models of greenhouses with opening top
Today there is a large selection of different models of greenhouses with a roof that opens from above. Among them are the three most common types of greenhouses: "Present", "Nurse-clever" and "Matryoshka". Each of them has its advantages and features.
"Gift"
"Present" - a greenhouse opening from the top, has an arched frame shape. Details are made of a profile pipe, with a size in section of 33 * 33 mm. Since the pipe is covered with zinc on all sides, it prevents corrosion. Pipe wall thickness of 1 mm. Since the roof of the greenhouse "Present" is presented in the form of sliding panels, the manufacturer did not install excess struts and arcs for the winter period, because the roof "descends". Therefore, the distance between the arches is 2 m. The standard width of the greenhouse is 3 m, and the height is 2.2 m. Thanks to the modular insert, the greenhouse length can be different: 4.2 m, 6.3 m and so on. 
Did you know? Sliding panels are located in the grooves of the side parts of the greenhouse and can be selectively shifted for good ventilation.In winter, the panels are best moved down completely, this is necessary so that the snow gets inside the greenhouse, and the ground is frozen. In addition, if you move the panels, you will not need to strengthen the greenhouse with supports. Since the greenhouse has a retractable roof, there is no need to furnish the "Prezent" greenhouse with vents. At the ends of the installed doors in the greenhouse, which can be opened at 180 °.
"Nurse-clever"
The greenhouse "Nurse-clever" with an opening top is made of a square steel pipe with a polymer coating of 20 * 20 mm. Arches of an arched structure are installed through each meter, the wall thickness is 1.5 mm, the greenhouse length is from 4 to 10 m, and the width is 3 m. Increase the length of the greenhouse can be phased. Some manufacturers of the greenhouse "Nurse-clever" make its walls with a thickness of 1.2 mm. Therefore, gardeners often have doubts about its strength. However, those who have already purchased this greenhouse model, say with confidence that although the frame seems thin, but in fact it is quite reliable.
Important! If a new greenhouse, "Smart nurse" with a retractable roof will crush with snow (if it was closed), then the manufacturer undertakes to replace it completely.At the ends of the greenhouse there are 2 vents and 2 doors. Polycarbonate coating provides the necessary illumination as well as UV protection. This coating also protects the greenhouse from corrosion. Among the peculiarities of the polycarbonate greenhouse “Nurse-clever”, it is worth noting its fully opening roof with a winch, which even a child can easily roll.
"Matryoshka"
The Matryoshka models are polycarbonate greenhouses with an opening top. In contrast to the greenhouse-cabriolet, the roof here is not shifted downwards, but to the side, according to the principle of layering sheets on each other. Sliding the roof can in one direction, it does not take a lot of effort, everything is quite simple. However, gardeners point out one drawback of this design. Part of the premises remains under a canopy, and as a result, the snow does not cover this piece of land, so they have to settle it on their own.
This type of greenhouse looks very compact, in no way inferior to a convertible greenhouse. Greenhouse "Matryoshka" is ideal for those who grow plants with the same requirements for the microclimate. The roof of the greenhouse "Matryoshka" cannot be moved in parts, therefore it is impossible to arrange different zones for different cultures. 
How to install a greenhouse with opening roof
In order to install a greenhouse with an opening top, first of all you need to assemble a frame of galvanized profile. The lower ends of the risers must be dug into the ground or attached to the base. In the case when the supports of the greenhouse cannot be deepened into the soil, transverse slopes should be attached to them, this is necessary for stability.
Important! The lower part of the greenhouse with an opening top can be insulated, for this use foam sheets. However, it should be borne in mind that this material is very fond of the mouse.If you decide to make a greenhouse with low-level insulation, you can use any other available materials. With the help of furniture corners polycarbonate sheets are attached to the structure. If you use old window frames in your construction, then bricks can be used as a foundation. In order for the roof to open, you need to put two end stops. If you have a building material such as polycarbonate, then everyone can assemble a greenhouse. You do not need any special tools to assemble the structure, and there are nails, screws, a screwdriver and a hammer in every household.
Features of operation of greenhouses with sliding mechanism
The most important and indispensable condition for the proper operation of greenhouses with a sliding mechanism is the need to push the roof completely for the time of winter. Such facilities should be regularly cleaned, if necessary - repaired. All drop-down greenhouses require proper and careful installation. Before planting and after harvesting, the walls of the greenhouse must be well treated with disinfectants. Also should be treated and prepare the soil.
