The greenhouse makes it possible to grow a huge variety of crops, including quite exotic ones. That is why many gardeners are embarking on its construction, however, not all of the existing projects can boast really effective. This article will describe the main features of the Nursing Home-Umnitsa greenhouse with an opening top, as well as the main advantages and disadvantages of the structure.

Design features of the “Umnitsa” greenhouse

This building compares favorably with many greenhouses. First of all, the construction allows you to get better and more saturated fruits with useful substances, which is achieved thanks to special structural capabilities. However, before building a greenhouse, you must definitely look at its shortcomings.

Benefits

• The main advantages of "Clever":
• this structure is a product of industrial production, therefore, it is distinguished by reliability and perfect design;
• the basis of the design are only high-quality materials, which provides it with a long service life;
• the scheme of the greenhouse is quite simple, so almost everyone can assemble it;
• the created structure is quite light, therefore it does not require a deep and thorough foundation;
• the design is often distinguished by a retractable roof, this allows airing, and also provides plants with natural pollination;
• It makes it possible to provide natural litter and snow cover on the soil, which improves the quality of the substrate and its mechanical structure;
• does not require huge areas, so it can be installed even on a small area, an area of ​​one hundred square meters;
• a removable roof avoids the snow load of the structure, which extends its operational capabilities at times.

Disadvantages

• "Clever" does not have many shortcomings, the main ones are the following features:
• this model will require considerable investments;
• To reduce the cost of the construction, cheap plastic panels are often used, they are characterized by low mechanical strength and low resistance to solar ultraviolet;
• the technical components of the structure consist of complex factory-made elements, therefore, in case of damage, it is quite difficult to repair them.

Did you know? The greenhouse "Umnitsa" is a product of Russian engineering. It was manufactured and designed on the basis of the Metal Service production event (Novosibirsk), in 2010.

Choosing the best greenhouse option

Today, this type of greenhouse allows you to create on the site a design of almost any size and shape. At the same time, the gardener has to go through several simple, but at the same time important steps. Behind them is significant preparatory work, which often affects the efficiency of the greenhouse and its mechanical strength. In addition, during this, it is imperative to determine the model of the greenhouse.There are two popular models on the market today:

• nurse - is a monolithic dome with a fixed roof;
• standard plus - A more expensive model, however, a system is installed in it that allows you to open the roof. Often it has an automatic control unit and microclimate control, in which case the building becomes the so-called "smart greenhouse".

Size selection

The selection of optimal design dimensions is considered the most important step. They determine it according to the area of ​​the plot suitable for the construction, which must meet certain requirements. If they are observed, an optimal microclimate is created inside the greenhouse for the successful development of almost any cultivated plant.

First of all, it is necessary to pay attention to the illumination, the greenhouse must be in a bright, well-lit area. To do this, choose a place away from any outbuildings and no closer than 2-3 m from the tree vegetation.It is also desirable that the structure is located on the long side in the south, this will subsequently lead to a more active and efficient heating. It is best to build a greenhouse in the depths of the site, this will help to avoid sudden changes in temperature and winds.

Important! It is not recommended to place the greenhouse near the fences, in this place the snow melts much longer, which leads to undesirable overcooling of the soil.

Coverage selection

The coating of the entire structure can be made of various materials. Polycarbonate can be called the best option for equipment. It is a porous sheet of high strength plastic. Such material provides excellent light transmission, and also allows the construction of lightweight, but reliable structures.If necessary, polycarbonate can be replaced with any other alternative. To reduce the cost of the greenhouse, it is often replaced with thick PVC sheets, plastic film or spanbond. A more expensive alternative to sheltering walls and roof is glass. Besides the fact that it is several times more expensive than plastic materials, its use requires a more complex structure, requiring a well-designed foundation. However, such a greenhouse will have good heat-insulating properties and light transmission, which is important enough for the cultivation of particularly heat-loving species.

How to assemble a greenhouse "Clever" do it yourself: step-by-step instructions

After you have decided on all the structural features of the future structure, you can proceed with the installation of the “gardener assistant”. However, often many farmers simply have no idea how to assemble it correctly and what to begin with first of all. The installation often consists of just a few successive steps, including the installation of the foundation, the installation of the frame and then the cover panels.

Foundation selection

The foundation is considered the foundation of any structure, the durability of the entire structure depends on its successful laying. The foundation can be made using a variety of techniques and even from improvised materials. Most often it is created in the form of a monolithic structure made of concrete or brick up to 50 cm deep. This foundation allows you to create a solid and indestructible foundation that will support the structure for many years.However, today more and more farmers are refusing such a technical solution as wasteful spending. Since the skeleton "Clever Ogorodnitsy" is a monolithic structure, it can be safely installed on open ground. Moreover, in order to avoid the influence of soil movement on it during the operation of the building, a small stand of a wooden beam with a section of 100 × 100 mm is installed under the frame.

Frame assembly

Collect frame elements based on the following steps:

1. Assembly of the ends. With the help of crab mounts and bolted joints, end arcs with a base are installed. Between the sides mounted stiffening ribs, increasing the mechanical strength of the ends. On one side, a doorway is installed in the form of a regular rectangle, which is attached to the end edges.
2. The connection of the ends. With spacers, two ends are attached to each other, and then installed in a constant place. After that, the others are attached to them, the assembled structure is strengthened by end arcs, which are fixed in the roof zone by means of struts.
3. Roof installation (in the case of a monolithic design, the step is skipped). A sliding system of rollers is installed on the finished frame. After that, small end arcs are interconnected using spacers, using bolts and special fasteners. Then the roof is mounted on the frame and fixed to the sliding system.
4. Door installation. After the whole structure is ready for cladding, the door frame is installed on the doorway with a hinge.

Did you know? The world's first modern greenhouse was made in Cologne, in 1240, in honor of the arrival of King William of the Netherlands in the city of Holland. Its founder was the German scientist and philosopher Albert Magnus.

Frame cladding

As mentioned above, polycarbonate is most often used as a skin for a building - it is a sufficiently durable and versatile material that does not require special tools for processing and fastening. It is often replaced with spanbond or dense polyethylene. Despite the fact that such materials are cheaper, they are unstable to ultraviolet, and therefore require replacement every season.Installation of the casing begins with the fastening of polycarbonate to the end panels. To do this, the sheets are cut to small squares covering the ends. Polycarbonate is attached to the ends with the help of roofing screws, directly to the frame with a step of 30 cm. After that, the ends of the sheathing are cut off in the shape of the ends, using a strong stationery knife or a small hand saw with a small tooth. After that, the doors are sheathed, and also with a step of 30 cm using roofing screws.

Next, the side walls are mounted, the installation is carried out in the same way as the installation of the ends. In this case, the sheets are fixed both to the bearing elements and to the stiffening ribs. Separate sheets are interconnected using connecting tapes. At the end, roof sheathing is carried out.

Important! Self-tapping screws should not pinch polycarbonate, otherwise it will crack during operation. And this will lead to depressurization of the greenhouse and the deterioration of its effectiveness.

It is best if it will consist of monolithic sheets, however, if necessary, they can be connected by hermetic connecting tapes. They fix it to the base with the help of roofing screws with sealing rubber.

Tips for the maintenance and operation of the Umnitsa greenhouse

To ensure an efficient and continuous operation of the greenhouse:

• in the off-season, it is mandatory to check the functionality of all technical nodes;
• periodically inspect and check all the connecting elements for strength;
• after harvest, remove all plant debris and contaminants;
• if possible, it is necessary to open the dome for the winter, because under the influence of the gravity of snow it can break through the roof. If the roof of the greenhouse does not have a sliding system, polycarbonate is dismantled;
• once every several years, treat all metal parts from corrosion.

The greenhouse "Umnitsa" is an excellent option for both professional and private crop production. Despite the considerable costs of the construction, it allows you to create a multi-functional durable construction. With its help, you can successfully grow almost any fruit crop, regardless of the climatic characteristics of the region. However, for this you need to carefully choose a place for the greenhouse, on which the microclimate inside the structure directly depends.
