Weather conditions do not always allow growing vegetables and flowers in open ground. Greenhouses and greenhouses are used for growing seedlings or for the full period of plant growth and fruit ripening.

1. They have a small height - no more than one and a half meters.
2. Lack of doors. The ability to access plants depends on the design of the greenhouse.
3. In greenhouses, artificial heating and lighting are often arranged. Greenhouses are heated only by solar energy and compost.
4. Unlike greenhouses, greenhouses are not only stationary, but also portable.
5. Greenhouses, simple in design, are installed for the period of growing crops.
6. For growing plants in winter period greenhouses are not suitable. For these purposes, they construct permanent greenhouses which are equipped with lighting and heating.

Only experienced gardeners understand such subtleties. It really doesn't matter what you call a protective device for growing seedlings or heat-loving plants. On sale, some designs have a double name - a greenhouse-greenhouse.

Types of greenhouses and greenhouses

Many people first buy and install a greenhouse, and then think about its advantages and disadvantages. When choosing a design, have clear answers to such questions:

• what crops are you going to grow;
• the location of the greenhouse;
• the possibility of summing up the power point for the lighting device;
• heating method;
• how much you are willing to spend on the purchase and installation of facilities.

Structures for the protection of soil and plants differ in location, design, material for the frame, type of coating and internal structure.

1. According to the method of location, the greenhouses are adjoining, which are attached to a standing building and stand-alone. Adjacent structures are often called wall structures.

Advantages of adjoining greenhouses:

• construction requires less costs than freestanding ones;
• there are no problems when summing up electricity and water;
• the possibility of an exit device to the greenhouse from the house.

The disadvantages include the fact that it is not always possible to install a greenhouse on the south side of the building and the need to create additional wall insulation from high humidity.

Advantages of stand-alone greenhouses:

• the possibility of choosing a form and design;
• optimal choice of location for installation;
• access to light from all directions.

The disadvantages include the complexity of summing up communications.

2. According to the construction method, greenhouses are capital and temporary. Capital types of greenhouses are installed on the foundation. The foundation is arranged along the perimeter of the greenhouse to the depth of soil freezing. Outside, the foundation is insulated with expanded clay or other heat-insulating material.

Temporary or portable greenhouses are convenient in that they can be installed elsewhere if you decide to change something on your site.

3. According to the height of the soil, there are two types of greenhouses - buried and ground.

For the construction of buried greenhouses, they dig a hole, cover the bottom with soil, and cover it with a film on top. In such greenhouses, early seedlings can be grown due to the fact that the soil freezes less than with the usual, ground-based method of arranging greenhouses. Mini-greenhouses are convenient for protecting plants in open ground.

4. According to the type of construction, greenhouses and greenhouses are divided into arched, polygonal, single-slope and gable. The shed design is mainly used in the construction of near-wall structures. Gable and arched structures are convenient, in which you can move to full height and plant plants in 2-3 rows.

5. Heating in greenhouses is possible in several types - electric, biological, water. The easiest and cheapest way to heat is a bucket of smoldering coals. When choosing a heating method, one should take into account what material the structure is covered with.

6. Plants are grown in the ground or in pots or boxes on racks. Racks are convenient for low-growing plants.

7. Plant nutrition can be soil or hydroponic. In the hydroponic method, plants are grown on aqueous solutions of substances necessary for crop growth. This method is not widely used among gardeners, it is used mainly when growing vegetables for sale and is not suitable for flowers.

What materials are used to make the frame

For the frame, wood, plastic and profile pipes, metal, fiberglass are used.

Coating for greenhouses and greenhouses

The choice of coating depends on the frame of the greenhouse.

1. Glass is used in wooden structures. It is used in permanent buildings or fixed in frames, from which a greenhouse is subsequently assembled. It is possible to use old window frames for building a greenhouse. Due to the complexity of installation and the fragility of the material, glass is becoming an increasingly unpopular coating material.
2. Greenhouse film, plain or reinforced, is used to cover all types of structures and is the cheapest material. The disadvantage of the film is a short service life.
3. The most durable coating is cellular polycarbonate. Polycarbonate is not recommended for PVC pipe frames. The incompatibility of the two types of plastic reduces the service life of the greenhouse to 3 years. A suitable frame option is from a galvanized profile or a galvanized profile pipe.

Types of polycarbonate greenhouses

Polycarbonate greenhouses have a number of advantages.

1. Ease of installation.
2. High strength.
3. Light weight.
4. Provide good light transmission.
5. They have high thermal insulation characteristics.

The disadvantage is the high cost. Building a greenhouse with your own hands will cost you less than buying a finished one.

Greenhouses differ in shape, design, number and arrangement of hatches.

Butterfly greenhouse. The design allows for maximum access of light to plants in sunny weather.

Greenhouse-bread box (snail) has a very comfortable design.

Belgian greenhouse with a pitched roof. The roof can be raised for ventilation or fully reclined.

What to consider when installing greenhouses and greenhouses

1. Choice of location. The greenhouse is installed with ends from north to south at the place of maximum illumination of the site.
2. Do not assemble a plastic coated greenhouse at low temperatures. The optimum temperature for installation is 10-12º above zero.
3. When using a polycarbonate cover, choose an arched type of greenhouse construction. This type of construction will protect the coating from damage in the winter.
4. Buy high-quality polycarbonate with a thickness of at least 4 mm. In appearance, the plastic sheet should be transparent without any inclusions.
5. For installation, use fittings intended for the installation of polycarbonate - thermal washers, press washers, sealing tapes, end edging profiles, bead seals for sealing.
6. Install partitions in greenhouses where you plan to grow different cultures. This will help avoid cross-pollination of plants.

Building a greenhouse with your own hands.

let's consider modern views greenhouses for personal plots.

With the advent of polycarbonate on the market, almost all designs of modern greenhouses are focused on covering with this particular material.

This is justified by its performance and relatively low and ever decreasing price.

Advantages of polycarbonate:
Ultra-high impact strength (cellular polycarbonate with low weight is 200 times stronger than glass and 8 times stronger than acrylic plastics and PVC).

High temperature resistance

High fire resistance

Extreme lightness, small specific gravity(cellular polycarbonate weighs 16 times less than glass and 3 times less than acrylic of the same thickness)

High thermal insulation properties, low thermal conductivity

High light transmission (up to 86% transparency)

Good noise and sound insulation

High chemical resistance

Flexural and tensile strength

Excellent weather resistance

Durability, invariance of properties (warranty period of service of polycarbonate products is 10-12 years

Safety and ease of coating (polycarbonate does not break, does not crack, and therefore sharp fragments upon impact)

Protection against ultraviolet radiation (a special protective layer prevents the most harmful UV radiation from penetrating the interior)

Excellent structural possibilities, the lightness of the sheets allows you to create light, original and elegant designs.

Its disadvantages:

If the sheet is not positioned correctly (with UV protection inside), then its service life will be reduced from 10 to 2-3 years.

It also has a hollow structure, where dirt and water will very often get into. This leads to a deterioration in light transmission and a faster loss of heat, which is not desirable in our conditions. also spoils appearance. Agree when plastic near the ground has black-green color it's not very pretty. That's why .

Under polycarbonate, frames are also made and built, they differ in shape and in the use of material.

By shape: the most common are arched and tent (house), the rest are variations of these two.

Arched. These are mostly factory-made greenhouses.

Their advantages:
Ease of assembly;
Low cost;
Less consumption of polycarbonate.

Flaw:
Little functionality;
The small height of the extreme beds.

Good for low crops (pepper, eggplant)

Tent. This form of construction is often chosen for self-construction, but there are also factory options.

Their advantages:
Individuality of designs;
Non-standard sizes for any crops;
Good functionality.

Flaw:
The need to use a more durable material for the frame, taking into account the increased snow load;
higher cost;
Higher consumption of polycarbonate in terms of area.

The materials from which the frames are made:

Omega or as it is also called for its shape "hat" profile.

Advantages:

1. You can take it away in a car.
2. Reliable protection frame from corrosion. Usually galvanized sheet does not rust for about 6-8 years.
3. Low price due to streaming production and little use of manual labor.

Of the minuses:
1. It takes a very long time to collect. For example, for an 8 meter greenhouse, 1210 bolted connections must be tightened. You will understand how much time you will spend if you tighten 10 bolts, add 5 minutes to read the instructions and multiply the resulting time by 121. By the way, this may take more than one day.
2. Most frames of this type, according to the passport, can withstand up to 20 kg / m2 of snow. Those. in the event of a snowfall, it is necessary to remove the snow from the plastic cover almost immediately. The exception is the Volya company, which produces really strong frames, but also at a fairly high price, which exceeds the price of greenhouses from a profile pipe.
3. Due to streaming production, there are: mismatched holes, missing holes. There are frequent cases of incomplete equipment or equipment with unnecessary parts.

Profile pipe (square, rectangular).

Let's list the advantages:
1. Available as all-welded and collapsible, the ability to make it yourself.
2. Due to the presence of a minimum number of connections, the frame can be assembled in 1-2 hours. The entire greenhouse is assembled in 4-5 hours.
3. Withstands heavy snow loads. For example: Favorit, Novator, Grand, Kremlin have a reinforced frame that can withstand loads from 180 to 250 kg / sq. m. And each arc can withstand a load of 250 to 350 kg.
4. Installation both on the foundation and on the ground without any problems.

Of the minuses:
1. Higher cost.
2. The need for painting.
3. Large dimensions during transportation, especially all-welded ones, and they are the most durable.

Wooden:
They are made independently from linear timber.

Pros:
1. The ability to build independently according to your drawings without having the skill of a welder.
2. Warmer due to low thermal conductivity.
3. Simplicity and reliability in fixing the roof.

Minuses:
1. High price.
2. Lack of factory blanks.
3. The need for protection with an antiseptic.
4. Complexity and duration in manufacturing.

Other materials, such as angle or round pipe, are rare and, in my opinion, are only reasonable if you already have this material in stock.

Based on this assessment, the following factors should be considered when choosing a greenhouse:
1. Place of residence, taking into account the snow load.
2. The culture you are going to grow.
3. Possibility of improvement if necessary (auto-ventilation, drip irrigation, etc.).
4. Availability of finance
5.Own craftsmanship.

Using greenhouses to grow flowers and crops is a win-win.

It protects plants from adverse climatic conditions and allows them to be grown all year round.

The design consists of the main cover and the frame to which it is attached. The choice of material and configuration for the base is strictly regulated by established standards.

For the construction of the frame, galvanized or steel profiles of rectangular or square section are applicable. Each of the materials has its own advantages and disadvantages.

Frame types

Feature of a galvanized profile in budgetary cost and small weight. However, such a frame cannot be called durable. To give stability during assembly, use a large number of elements.

Connecting parts require additional reinforcement. This is a rather light construction, therefore it should not be installed with heavy rainfall and strong winds.

Rectangular steel bases are difficult to manufacture, which affects their final cost.

Possessing increased resistance to mechanical stress, the material requires additional treatment against rust and corrosion.

Here are a few things to keep in mind when choosing a frame:

• The thickness of the metal must be at least 1.2 mm;
• It is advisable to choose designs with solid arcs;

Preference is given to profiles with a square or rectangular section, the ideal parameters of which are 20 x 40 millimeters. Before buying, it is advisable to familiarize yourself with the proposed copies.

Choice of polycarbonate

Good ones performance characteristics greenhouses are conditioned the right choice coatings. It has been proven that polycarbonate is ideal for these purposes and more.

The choice of coating depends on the type of material, its thickness, as well as light transmission.

There are two main types of polycarbonate:

• Cellular (cellular).
• Monolithic.

The first option wins in its characteristics due to several layers of material and the presence of longitudinal bridges between them.

Such polycarbonate has a low weight, perfectly transmits light and is resistant to temperature fluctuations.

With its flexibility, the honeycomb material is highly resistant to mechanical stress. The light transmission of the material helps to create a greenhouse effect.

Polycarbonate, intended for exterior decoration, including greenhouses, is treated with a special compound that protects it from damaging UV rays.

The presence of such a coating is indicated by a mark on the package, “protective UV layer”.

The thickness of polycarbonate for greenhouses ranges from 4 to 10 millimeters. For arched structures, it is recommended to use thickened sheets. For vertical greenhouses, thinner sheets are suitable.

Construction type

Among the many configurations, the most common are greenhouses in the form of an arch, wall structures, single-sided or double-sided.

The choice of the type of greenhouse is determined by the financial capabilities of the buyer, as well as directly by its purpose.

The first to appear was a double-sided greenhouse. Outwardly, it resembles a small country house with a flat roof and vertical walls. This is the easiest type for installation and, moreover, the most affordable financially.

Shed or in other words wall structures are installed on the sunny side. Maximum roof pitch.

Only in this way will it be possible to avoid stagnation of snow. The main support is the wall of the house or outbuilding.

The greenhouse, whose shape resembles a drop, has additional stiffeners, which makes the whole structure more stable.

Arched greenhouses can be solid and have only one entrance, or have lifting side walls. The second option is convenient in that it provides free access to the beds and makes it possible to fully ventilate the room.

Regardless of the design, polycarbonate greenhouses must be securely attached to the foundation. The base of the steel frame is usually welded, and the galvanized steel is fastened with dowels and anchors.

To date, the size of greenhouses is practically unlimited, and their choice depends on the size of the site itself, on which they will be installed.

Greenhouse designs and equipment vary greatly depending on what time of year they will be used and your preferences.

In recent years, mobile greenhouses have become popular. By design, they are rectangular, arched, block-arched and hangar.

During the season, 2-3 times the greenhouse is sequentially moved from one crop to another. Movement is carried out with the help of tractors, cables and winches. All operations for tillage, making ridges, sowing, and sometimes planting are performed by ordinary machines, after which the greenhouse is moved to the prepared area.

The simplest rectangular greenhouses (with a gable roof) may consist of an aluminum frame on which a plastic film is stretched. The optimal dimensions of such a greenhouse are: length (assembled) - 4-5 m, width - 2.0-2.2 m, height - 1.80 -2.00 m. The film coating is attached to the frame through rubber gaskets with flat spring clips . The frame of such a greenhouse is tubes interconnected by brackets. Stretch wires are needed to eliminate warps and sagging of the film. The greenhouse should be provided with opposite curtain doors through which the structure can be ventilated. Including, if necessary, you can fold the side of the film.

There is another type of the simplest greenhouse - arched (the so-called "metro"). The optimal dimensions of such a greenhouse can be the same as those of the first one, i.e. designed for two beds and a passage between them.

Typically, the frame of such an arched greenhouse consists of five to six arcs made of profiled duralumin alloys and connected by four to five longitudinal ties.

The film is attached to the frame with wire, starting from one of the ends. The assembled greenhouse is installed and fixed with fixing pins. They are driven into the ground through holes in the brackets. The lower free ends of the film are pressed to the ground with bulk earth or some kind of load. Such greenhouses are recommended to be disassembled for the winter and stored indoors.

Shed capital greenhouses

Unlike previous versions of greenhouses, which can be transferred annually, or even several times per season, there are. Least cost requires the construction of a shed greenhouse. For a better light regime and warming up, such greenhouses are oriented to the south or southwest. They can be cold - without heating, with a pit and without a pit. In the simplest case, amateurs build shed greenhouses from two to four greenhouse frames. The optimal slope of the frames along the horizon, regardless of whether they are with glass or with a film, is 45 degrees. Frames can be glazed or covered with one or two layers of film.

The walls of the greenhouse form vertically placed greenhouse frames, resting on the lower trim and with the upper end entering the quarter formed by the board sewn on the racks. Boards are sewn along the top of the racks, forming a stop for the lower end of the obliquely laid greenhouse roof frames. In the upper part of the frame, they are inserted into a quarter selected in a ridge beam, or placed on a rail nailed to it.

An even simpler option is a shed wall greenhouse. Such greenhouses are usually attached to the southern wall of the house or hozblok. This allows you to save space on the site.

Shed wall greenhouse

The device of the greenhouse begins with digging a pit, making its walls sheer. With a greenhouse area of ​​22.5 sq. m of a pit, they dig a length of 10 m, a width of 2.25 m and a depth of 1.1 m.

The frame of the greenhouse consists of four pillars with a diameter of at least 20 cm, a height of 3-3.5 m, installed in pits at a distance of 3.33 m from one another. The width of the pits for the pillars is 0.25 m, the length is -0.5 m, the depth is from 0.5 to 1 m, depending on the soil. Two bricks are laid at the bottom of the pits along and two across, fastening them with cement mortar. This is the foundation for the pillars.

Before installation, the lower ends of the pillars are tarred or fired to prevent decay. Install the posts close to the wall and fix them with building brackets. Small gravel is poured into the pits, poured with cement mortar and compacted.

The upper bed, 15 cm thick, is placed on poles, the lower and two crossbars are placed on bricks laid in one row along the outer edge of the pit.

Bricks for strength are fastened with cement mortar. The gaps between the walls and the bed are caulked. The upper and lower beds are fastened to one another with bars 12 cm thick cut into them. Bars are cut between the slopes at a distance of 1.2-1.5 m. The film is pulled from the outside, nailed with a thin rail to the bars, and from the inside (from the greenhouse) . The resulting gap between the layers of the film, equal to the thickness of the bed, contributes to the preservation of heat. The inner layer of the film is fixed with a rail along the perimeter of the roof to the upper and lower beds and the beam connecting them.

The door frame for entering the greenhouse is made together with the frame. The first pillar of the frame serves as a jamb for the door. For the second jamb, a pole 2 m long is installed under the slope, which is buried 0.4 m into the ground. The side jambs are interconnected at the top with a jamb, at the bottom with a threshold. The height of the door is 1.6 m. In the door frame, a groove is selected for the door, which is opened outward. The door is made of boards or a double layer of film. To preserve heat, the vestibule is covered with a film, for which they put 2 more pillars 10 cm thick and 2 m long, which are also deepened by 0.4 m. The pillars are connected by jambs and crossbars. The door to the vestibule is made in the same way as to the greenhouse.

Gable capital greenhouses

In garden plots, a rectangular greenhouse with a gable roof, two retractable vents and hinged doors has become widespread. It can be under glass or under film cover.

They are placed on a foundation, which is made of concrete, brick or wooden beams. Its height along the ridge is 2.5-3 m, width - up to 4 m, length - 6-8 m or more. Such greenhouses can be 100-110 cm deep in the ground. In this case, they retain heat better. Vegetables are grown on racks. Well-established and prefabricated greenhouses. They are made from light frames or in the form of a frame covered with a film. Their width is 2.4-3.6 m, length - 6-7.2 m. Arched greenhouses made of bent metal structures or polyethylene arcs are found in vegetable gardens. The basis of such greenhouses are wooden bars (section 10 × 10 cm). The ends of the arcs are inserted into the inner cutouts of the bars and secured with brackets or strips. Ventilation of arched greenhouses is carried out through the end doors.

The main difference of the greenhouse according to the Mittlider design is a two-level roof, which allows you to make a ridge transom stretching along the entire roof, from end to end. This transom is a functional vent that effectively ventilates the greenhouse.

The shape of this greenhouse is based on a gable structure with vertical walls. But a variant made on the basis of an arched greenhouse is also possible. In both cases, a film coating is used.

The disadvantage of a conventional arched greenhouse is difficult ventilation. The air passing through the door cannot displace the warm air mass that has gathered under the ceiling. Such a disadvantage is also present in a film gable greenhouse, in which ventilation is carried out through a small window, and at worst through a door.

In Mittlider's greenhouse, there is a transom at the top, which is large in area. As a result, the cold air coming from it displaces the warm air and then spreads throughout the greenhouse. Therefore, such a greenhouse is ventilated remarkably. In the improved design of Mittlider's gable greenhouse, the presence of two transoms is generally assumed: one is located under the southern slope, the second is above it under the ridge.

In a similar arched-type greenhouse, where a second transom is not possible, its role is partly played by a door or a window above the door. With such ventilation, plants are not subject to overheating, even when the air temperature is quite high. Mittlider's greenhouse is located so that the transoms look south. Due to this, the cold north wind, which can cause hypothermia of plants, does not penetrate the structure.

This design provides for a solid frame, which is achieved by installing beams around the entire perimeter of the greenhouse at a distance of 2 m. In addition, building braces are installed in the corner joints of beams with end posts - elements that provide additional structural rigidity. Due to the high strength of the frame, the greenhouse easily resists strong gusts of wind, snowfalls and hailstorms. Through effective ventilation, carbon dioxide is supplied to plants, which is necessary for photosynthesis. Condensation does not accumulate on wooden supporting structures, as on metal parts. Mittlider's greenhouse is conveniently positioned with transverse horizontal beams that are taller than human height, due to which the side walls are strictly vertical, and not inclined. This makes working in the greenhouse more comfortable and allows them to be used for tying tall plants.

domed greenhouses

A greenhouse of such a plan is more element design than a functional building. But it is convenient when a very large tall plant needs to be planted in the center, and smaller ones on the sides. It is suitable for various tropical trees. Winter dome-shaped greenhouses look very nice, which are green oases in the middle of a snow-covered garden.

It should be noted that this design is characterized by high strength and stability due to its shape. The lighting inside the greenhouse is also very good, as light can come in from any direction throughout the day. The disadvantage of the design lies in the limited dimensions, which is why it is not always convenient to work in such a greenhouse - often there is simply no way to straighten up to its full height. But this applies only to small-sized domes.

The frame of a domed greenhouse, as a rule, is made of metal, using aluminum frames, glass or polycarbonate is chosen as a coating. Frames are made triangular or polygonal. It is difficult to make such a greenhouse with your own hands, and therefore, ready-made prefabricated models are used for its construction.

polygonal greenhouses

This type of construction practically does not differ from domed ones and also serves as an element of decor. Such a greenhouse can be a wonderful small winter garden, where it is pleasant to go on rainy or frosty days, as in a flowering gazebo.

The walls of the polygonal greenhouse are located vertically, and the roof is a truncated cone, made up of several frames that have the shape of an irregular quadrangle. It is advisable to make polygonal greenhouses winter: with good heating, glazed or covered with polycarbonate.

Others - those who see the greenhouse as a business or household help - have more demanding performance requirements; for them, her appearance also plays an important role, but not the most important.

Decide why you need a greenhouse

Moreover, if in the first case your hobby will require insignificant financial costs, then in the second the greenhouse will be a significant investment, the size of which will subsequently depend on your expenses for its maintenance.

Stationary or collapsible?

Decide what you intend to grow in the greenhouse

In a greenhouse, you can grow different and even - it's up to you, but keep in mind: different greenhouse crops differ in both growing modes and requirements for and. Some plants you can grow together, others will not tolerate any neighborhood and - moreover - will only harm each other. Articles will tell you more about this: Having decided on which plants you are going to grow, you can choose a greenhouse of a suitable height. Agree: it's one thing to grow, and quite another - cucumbers or tomatoes. So, if you decide to grow tomatoes, it is better to purchase a high rectangular greenhouse "house", it is ideal for tall plants.

Decide on a growing and watering system

1. on soil - soil (the most common growing system),
2. or on a variety of substrates (organic or mineral) - on peat mixtures, coconut substrate, expanded clay, tuff, perlite, mineral wool or vermiculite.

Photo from the site

Or maybe you decide to grow plants using - a method that is a system of growing and watering at the same time? If so, please note that hydroponic systems also have several subspecies:

• wick passive systems and intermittent flooding systems,
• floating platform systems
• as well as aeroponic systems.

But if it will be possible to somehow influence all the listed parameters after buying a greenhouse, then it is unlikely to affect the place of its installation. That is why before you buy a greenhouse, decide where exactly it will be installed.

country greenhouse should use solar energy with maximum productivity, and there may not be many such places on the site, and their size also varies. You do not want to purchase a huge 10-meter greenhouse, which in the end simply will not fit in the planned installation site?

Photo from the site

Remember: greenhouses for summer cottages are installed in place, as much as possible and drafts. After all, on temperature regime inside the greenhouse, external airflow directly affects, due to which the air can either heat up sharply, or vice versa, cool excessively. It is necessary to position the greenhouse in such a way that it is maximally illuminated by the sun throughout the day: it is desirable to install it in length from north to south.

Everyone, having decided to buy a greenhouse, hopes to minimize the cost of acquiring it, while the benefits should also be maximum. Let's try to figure it out: is this possible, and will the reduction in costs lead to a significant deterioration in the performance of the greenhouse?

What are greenhouses? materials

Cellular polycarbonate

Photo from the site

Thanks to this property, a polycarbonate greenhouse is not afraid of heavy rain, gusty winds and even hail. Another significant advantage of polycarbonate is its long service life - over time (warranty for this material is 15 years) it will not lose its transparency.

You can learn about other advantages of this material and the nuances of its choice and application from the publications: Traditional materials have not lost their popularity, for example ...

Polyethylene film

Photo from the site

It is quite easily fixed on the greenhouse of any design, perfectly passes ultra-violet rays necessary for the normal development of plants, and serves as an excellent protection for the "inhabitants" of the greenhouse from small (up to -3 ° C). It has a density of 100 to 150 microns and a sleeve width of 1 to 3 meters.

Reinforced polyethylene film

Photo from the site

It is produced in rolls, the width of which is about 2 meters, with a density of 200 microns, and it can be used for several seasons in a row.

Covering material spunbond

Photo from the site

It is able to protect plants from frost down to -7 ° C, and it can be used for about 5 consecutive seasons.

Greenhouse shape

• have a single or gable roof and vertical walls,
• be arched, arched with vertical walls,
• have the shape of a pyramid - greenhouses-pyramids.

Rectangular greenhouse with gable roof

In addition, it is very convenient and easy to use, which, you see, is also important. But let's see, nevertheless, what other form a country greenhouse can have.

wall greenhouse

They are deservedly considered one of the most economical, because thanks to this design, it is possible to significantly save both on and on placement, which, you see, is important, especially if the area of ​​\u200b\u200bthe site is limited. There is practically no difference on which side of the building you attach a shed greenhouse, although it is advisable to direct the slope of its roof to the south side.

arched greenhouse

Photo from the site

It costs quite inexpensively, and due to the fact that there are no sharp corners in its design, you will need several times less covering material than, for example, a rectangular greenhouse of the same size. Also, it is precisely because of this that its service life will be significantly extended.

Greenhouse-pyramid

Both the advantages and disadvantages of the pyramid greenhouse are still unknown. The only thing that can be stated with certainty is that the pyramid greenhouse is distinguished by its spectacular shape and complexity of execution, although if there is a desire to build such a structure in your garden plot, then why not.

polygonal greenhouse

It is usually constructed from wood or metal combined with glass. Such a greenhouse is quite practical, because each of its faces is heated at different times of the day rays of the sun.

Pros and cons of different types of greenhouses

• So, for example, cover arched greenhouse you can do it in just an hour, but it will be more difficult to take care of the plants growing in it: of course, access to the plants that grow near the aisle will be excellent, which cannot be said about the plants planted in the extreme row - to get to them you will have to stand on your knees.
• In case of shed roof you can work in a greenhouse quite comfortably, but to cover such a roof, you will have to make a lot of effort - this must be done only in dry and always calm weather, otherwise the film will flutter in the wind, and a little later it will simply sag. Of course, if you use glass or plastic instead of film, this problem will not arise.
• It has its drawbacks and: in addition to being one of the most expensive, it is quite difficult to maintain a stable temperature in it. But on the other hand, thanks to its original shape, it will become a worthy decoration of any garden plot.
