The use of polycarbonate greenhouses allows for a shorter time to get a high-quality and large crop, so the acquisition of such modern greenhouse structures has become an important aspect in the development of private and industrial agricultural enterprises. One of the most sought after models is the 2-Doom.

Technical characteristics and equipment of the greenhouse

The manufacturing company is the Volia enterprise, which has established itself as the creator of strong and reliable structures made of metal profiles among hundreds of gardeners and gardeners from amateurs to professionals.

The frame of the structure is made of a metal profile with a large coefficient of snow load, which is 120 kg / m². The end parts of the greenhouse have doorways, one on the opposite sides, into which the door and the ventilation window are built. The length of the structure can vary from 4 to 12 m, using additional inserts it can be increased to the required size.

Other parameters are close to the standard:

width - 3 m;
height - 2 m.

The greenhouse frame is fastened using special endings in the form of the letter T. The greenhouse is covered with polycarbonate panels on top. Indoors, at the joining points of polycarbonate sheets, struts are installed to make the structure stiff, they can be located every 0.5–1 m.

To cover the frame, polycarbonate is used, the thickness of which is 4 mm. It contributes to the distribution of sunlight in such a way that there is an almost uniform flow of light to the crops grown from all sides. This thickness provides the necessary protection from such difficult weather conditions as snowfall, hail, strong wind.

Did you know? A paradise project was implemented in England - artificially created biomes, or biospheres, in which there are millions of plants from different parts of the world. They are divided by climatic zones and are located on 1,6 thousand m². The dome of the structure is gigantic and has a height of 55 m with a width of 100 m and a length of 200 m. Almost half of the water for irrigation is taken from water reservoirs, where rain water is collected.

Benefits

The modern summer cottage greenhouse "2-Dum" has a lot of advantages among other similar structures, since in the process of its design many nuances and shortcomings of previous models were taken into account.

The main positive qualities include:
the ability to change the dimensions of the structure in accordance with the size of the summer cottage and the availability of free space;
window leaves in opposite parts of the greenhouse, which allow you to create the necessary ventilation to eliminate high humidity;
the ability to install additional stiffening ribs, if necessary, to strengthen the structural strength, if there is a possibility of a large amount of snow falling;
ease of transportation, since the greenhouse is sold disassembled, the parts are compactly packed and do not take up much space;
the package includes all parts and materials necessary for the construction of the structure;
the metal profile frame is protected against corrosion due to galvanized coating;
the greenhouse can be assembled independently, since all the details are numbered;
This model does not require disassembly for the winter.

Disadvantages

Negative reviews about the 2-Dum greenhouse were not noted at farmers' and horticultural forums, however, it is worth noting that the assembly of the structure should be carried out in accordance with the manufacturer's technology. Particular attention should be paid to the installation of polycarbonate profiles, since there is the possibility of damage to sheets, which, for all their strength, are fragile at the edges.

In addition, if the sheets are not installed correctly, scratches may appear on them, which can affect the life of the greenhouse. The disadvantages also include difficulties with independent fastening of doors, so often for the construction of a structure there is a need to seek help from professionals.

Buying Criteria

When considering options for polycarbonate greenhouses, first of all, you should pay attention to such criteria:

durability according to the passport;
the presence of hot galvanized coating;
the profile of the frame must be open;
the distance between arched arches should be no more than 1 m;
polycarbonate thickness and the presence of a light stabilizing layer;
convenient form of construction.

As already mentioned, the 2-Dum greenhouse meets these criteria, therefore it is ideal for growing tomatoes, eggplants, cucumbers and other vegetable crops in a summer cottage.

Build Features

Having opted for the 2-Dum greenhouse, you need to know what its equipment is:

in packaged form, the weight can be in the range of 60–120 kg, depending on the length;
polycarbonate sheets - 2.1 × 6 m (5 pcs.);
straight frame parts;
end;
accessories for installation;
arcs;
sealing profile.

When purchasing a greenhouse from a supplier, experienced gardeners advise you to seek professional help on site to create door and ventilation openings, indicating the required size of the window and door, since the polycarbonate in the kit is cut to construct the roof and side walls, and the end parts must be cut independently.

Nuts and screws are used to connect the polycarbonate sheets, however, it is worth remembering that it is impossible to fasten the joint panels in the joint, since they can be brittle at the edges, which can lead to cracks.

When installing U-shaped props for winter as an additional reinforcement, the number of arches must be taken into account. This will make it possible to significantly reduce the load on the greenhouse.

Important! Polycarbonate honeycombs must have a vertical position, which will not allow condensation to accumulate. Install it with the side with a protective film, labeled accordingly, outward, and the side with a transparent transportation coating should be facing inside the greenhouse.

In order to secure the loosening of nuts fastening the structure, which may occur over time, it is necessary to cover them with paint.

To ensure a longer daylight hours in a greenhouse, it may be necessary to install additional lighting:

reflex lamps;
fluorescent lamps;
high pressure sodium lamps, with photosynthetic effect.

Preparation for construction

In the process of preparing for the construction, the main point is the construction of the foundation, which will make it possible to more firmly strengthen the structure and use it for a long time. The manufacturer proposes to install the building using only a fastening with T-shaped legs, which can prevent the greenhouse from sagging, however, this cannot guarantee its stability under aggressive weather conditions, for example, hurricane winds.

Experienced farmers recommend establishing a foundation, the material for which can serve:

pipes or metal corners;
a rock;
thick wooden bars;
brick;
reinforced concrete.

For self-installation of the greenhouse "2-Doom" may require a lot of time. On average, it takes 2 days if you clearly follow the instructions in the instructions and follow the procedure for performing the actions.Greenhouse frame 2-Doom

Necessary tools

During the installation process, you may need:

stationery knife or jigsaw;
roulette;
Phillips screwdriver or screwdriver;
pliers.

Important! If metal structures are used to build the foundation, they must be coated with anti-corrosion material.

Step-by-step assembly instructions

All construction details have their own number indicated in the accompanying instructions for the greenhouse. There are illustrations with a detailed indication of all compounds.

The order of work is as follows:

The assembly of the frame begins with the end part. Part No. 2 (extension cord) is fixed with part No. 1 (arc) using 2 screws and nuts. Another 2 arcs are fixed in the same way. Then they add another extension cord.
Part No. 4 (stand) is attached to the middle arc using a corner.
Attach to part 4; part 6 (door extension). Assemble a second rack in the same way.
Part No. 5 (threshold) combines the racks at the top. The second part No. 5 connects 2 door extensions to the bottom of the structure.

Part No. 7 (the cross-section of the end part) is connected to the arc using a corner on one side and with a stand on the other side, being fixed with 2 screws and nuts. Correspondingly set and symmetrical to her part on the other hand.
At the end of part No. 3 (stringer), a corner is fixed, after which it is fixed perpendicular to the extension cord with two screws and nuts.
Set part No. 5 (threshold) with two holes in the direction of the stringer and four in the direction of the doorway, securing it with screws and nuts. On the other hand, the structures produce a similar assembly.
One end of part No. 8 (mowing) is connected to the end face with a screw and nut. The other end of the part is fixed at the junction of the door extension and the threshold. Set the mowing on the second side of the doorway.
Did you know? The very first greenhouses appeared in ancient China. In references to them it is said that they were built for growing plants at home, which were used to prepare medicinal decoctions and potions.
At the end of part No. 3 (stringer), a corner is fixed and the part is fixed with two screws and nuts perpendicular to the arc. The same procedure is carried out to install 4 more stringers.
The stringers are interconnected by parts forming another arc (parts No. 2 and No. 1).
Then stringers are lengthened, adding one more part No. 3 to them and fastening them with bolts. Then repeat the operation of fastening the stringers with an arc using parts No. 1 and No. 2.
Then half the frame, which is already assembled, must be turned over and installed in the place where it will stand in the future. The second half of the frame is collected in the same way.
Both halves are installed with a small gap between each other.
When assembling the basic kit, the last arc is assembled from parts No. 2 and No. 1 and is thrown onto one of the parts of the frame.
They move the two halves of the greenhouse and fasten the stringers with screws, then install the last arc at the place of their connection and fasten it with the whole structure with screws and nuts.

If the greenhouse will have a length greater than the standard, then all the necessary arcs are collected separately and thrown on one of the parts of the frame. Then connect part No. 3 (stringer) and No. 13 (spacer), which are installed between the assembled halves of the greenhouses. Then fix all the arcs to the desired location.
To give additional rigidity, parts No. 14 (amplifiers) are installed at the junction of arcs and arcs with extension cords. In the basic set there are 3 parts No. 14, which are installed on the middle arc. In the case of the construction of an elongated structure, the package includes 3 more such parts that are mounted on 4, 7, 10 arcs, in accordance with the number of extension sets, every 2 m.
In order to fix cellular polycarbonate, it is necessary to attach corners to the extension bars on both sides of the frame.

Next, assemble the doors. This process takes place separately from the installation of the frame of the greenhouse. After assembly, they are installed in place from one and the other end parts.

Then they are taken for the assembly of vents and their installation.

Greenhouse sheathing technology:

Start the process from the end. The sheet is marked and cut according to the sketch, after which the details are attached to the end of the frame. If their edges extend beyond the frame, pruning can be done with a clerical knife or a jigsaw.
Next, the roof sheathing is made by bending the polycarbonate sheets along the profile of the arcs. You need to know that polycarbonate sheets must overlap, and the excess at the edges will serve as a visor above the ends.
Next, the polycarbonate is fixed using either a polypropylene tape, which is attached to the frame parts with a buckle and tightened, or a metal tape, which is drawn by screws to the frame from both sides.
