Often, at a summer cottage, the need to build a small greenhouse is brewing, for example, when there is still no capital greenhouse. A small auxiliary structure is also indispensable, especially in the middle and northern latitudes, when growing tomatoes, cucumbers, peppers. It turns out that the easiest way is to build it with your own hands from scrap materials. Well, all the moments connected with this process deserve separate coverage.
What to make a greenhouse: types of materials at hand
Of course, the question of finding suitable parts arises immediately, as soon as the decision is made to build the described product. Although no one is experiencing difficulties here. Usually, any material available on the site or in the garage is used. Old window frames (this is the best option), and unnecessary easily bendable tubes or wires, coupled with plastic wrap, and old wooden blocks, and even plastic bottles will work!
Of these options, old window frames have a particular advantage.
- They accumulate heat well inside the greenhouse due to the rather thick glass.
- Often they can be obtained for free where plastic windows are installed.
- It is not difficult to mount them on the site into a common structure.
Frames are often made into a real greenhouse.
On the other hand, window frames are too bulky and heavy, and also have a very unaesthetic appearance, as the paint quickly peels off them. A greenhouse made of wire and plastic wrap can "boast" of other important advantages.
- It is very easy to mount it on the site - it takes literally half an hour.
- The material is easier to obtain than window frames.
But this design also does not shine with aesthetics.
It can be made large enough
Usually, when a decision is made of what to make a small greenhouse, the main argument is still the available arsenal. Hosts evaluate what they have or what is easiest for them to get. Consider the two most common options for making a greenhouse from the simplest materials - from window frames, as well as from wire.
Preparation for construction: dimensions, drawing and sketch
First, we will assemble a greenhouse from window frames. Its dimensions directly depend on the amount of available material. Suppose there are identical leaves in the size of 1 mx 0.5 m. Their number is 6 pieces. Then we are planning a greenhouse of the following type.
The long sidewalls will each consist of two flaps mounted on the largest rib. Then the ends of the greenhouse will turn out each of one part, laid on the long side.
Thus, the dimensions of our product will be:
- length - 2 m (1 + 1),
- width - 1 m,
- height - 0.5 m.
Let's draw a sketch for clarity. On paper, we indicate the dimensions of each frame, as well as the total length, width and height of our greenhouse. Everything can be done on a regular sheet with a pencil and a ruler.
In this case, a roof made of frames is also provided.
For ease of manufacturing, we will close the upper part of our product tightly with plastic wrap.
Also, at the preparation stage, it is necessary to choose a place for the greenhouse. This should be a sunny patch of good land, close to major plantings and water supplies. It is better to use the eastern part of the summer cottages, since vegetables grow better in the morning, and the sun rises in the east.
Calculation of the required material
Sometimes it also happens that they first plan a greenhouse, and then look for material. Suppose we decided to create a greenhouse 3 mx 2 m 1 m high, and cover it with foil on top as well. Then we need to find window frames by the following parameters.
- For each of the two long sides of the product, 6 sashes are required, each 0.5 m wide and 1 m high (6 x 0.5 = 3 m).
- For the ends of the greenhouse, 4 flaps of the same parameters are needed (0.5 + 0.5 + 0.5 + 0.5 = 2 m).
- The amount of film for a flat roof is calculated based on the length and width of the greenhouse: S = 3 x 2 = 6 m2.
After such a calculation, you can start looking for window frames.
Advice. It is better to select doors with well-preserved paint. Sometimes you can take a one-piece frame with two doors or with a window. The opening parts will serve as doors or vents in the greenhouse.
For work we need something from the standard arsenal of a carpenter.
- A hammer.
The last attribute is required to prepare the installation site.
Step-by-step instructions for making a greenhouse from window frames
We start work at a pre-selected location. In addition to the above criteria, they are often guided by the following consideration. The best place for a greenhouse is next to a large greenhouse for ease of maintenance.
- We determine one of the corners of the future greenhouse. This is an arbitrary point near the secondary path of the dacha. Usually the owner of the site imagines this corner in his imagination. The long side of the greenhouse will start from here. We drive in a peg.
- Align the strip for the window frames with a shovel. You can put boards covered with roofing felt to strengthen the support platform.
Old ones will do too
Place the first frame on the edge so that the peg of the imaginary corner is on the edge.
- To fix the window frame in a standing state, we drive small sticks into the ground in pairs on both sides of the rib of the part.
- We install the end flap and also fix it with pegs.
- We drive in nails on the side of the vertical bar of the frame, thus fastening two standing perpendicular parts. Metal corners can be used. They will add additional strength to the structure. In this case, instead of nails, it is allowed to use screws, but then you will need a screwdriver.
They also used metal fastening strips.
- We install a second flap for the long side of the greenhouse. We fix it with pegs.
- We fasten the frames with nails.
- We mount the flap of the second end of the greenhouse, repeating points 4 and 5.
- We collect the second part of the greenhouse, according to the processes already described.
- We fasten the end frames with nails. For the stability of the entire greenhouse, we also nail transverse wooden blocks with a meter step from above to the frames.
Diagonal stiffening ribs are also applied here.
At the same time, the transverse bars will serve as an additional support for the upper transparent coating.
- We cover the top of the structure with plastic wrap.
Here it is better to fix one end of the film on the end frames of the greenhouse with small nails with plastic washers, and wind the other on a strong metal tube as long as the width of the structure. Subsequently, the cover can be easily wrapped around this part to open up access to the plants.
The technology described here describes the manufacturing process of a structure in which long walls consist of at least two leaves or frames each. In the simplest case, a miniature greenhouse is made from four parts and a cover.
Easiest to do
In this case, you don't even need to prepare the foundation.
Step-by-step instructions for making a wire structure
Consider another common version of the described design. Its frame will consist of wire arcs. Only a strong and thick wire of any metal is needed. But at the same time, she must bend by hand.
In the manufacture of such a product, due to its extreme simplicity, you can do without a sketch.
The amount of material required is calculated based on the accepted dimensions of the structure.
How much material is needed
Let the wire product be 2 m long and 1 m wide. The height will be 1 m.Then, offhand, three standing arcs are enough for us, located with a step of 1 meter.
We calculate the length of the wire for each arc approximately. Since the height of the greenhouse is one meter and the width is the same, then we take a roughly sought value equal to 3 m (as if the arc looks like the letter "p"). Excess material will still sink into the ground during installation.
The total length of the wire is 3 meters x 3 pieces = 9 m.
The dimensions of the film with which we will cover the structure are obtained based on the approximate length of the arc, as well as the length of the greenhouse. That is, the dimensions of the coating are 3 mx 2 m. The ends can be left uncovered for ventilation.
Here, we only need a shovel and pointed pliers to cut the wire. Usually these blades are closer to the handles of the tool.
At worst, if there are no pliers, the material can be broken by hand, but for this it must be bent for a long time in reciprocating movements.
- According to the recommendations indicated earlier, we select a suitable place for a greenhouse.
- We separate from the coil of wire three segments 3 meters long each.
The incisors are clearly visible here
- We bend the wire with our hands, making an effort. In this case, you should get a regular parabolic arc with a height of 1 meter (not counting the segments at the ends for deepening into the ground). All measurements are carried out using a tape measure or by eye.
- We repeat the previous operation for two more wire segments. We fit all arcs to each other in size.
- We dig small holes in the ground with a shovel at equal distances from each other. These points will mark the outline of the future greenhouse.
- We insert the ends of the arcs into the pits and bury them, then carefully ram them. For greater strength, you can tighten the arcs with the same wire along the structure, top and bottom.
The place of the greenhouse was marked with black film
- We close the resulting frame with plastic wrap. You can fix it with tape.
Here, the ends were also covered with a film.
If the lateral end of the film is fastened to a long handle, then when opening the greenhouse, polyethylene can simply be wound on this stick, and in the closed (unrolled) state it will serve as a load for the film on the ground.
The simplest greenhouse is ready.

After making such a useful product, you can enjoy the process of growing vegetables in it. Maintenance of the greenhouse is practically not required - just know, check the stability of the structure during the summer. If necessary, something can be backed up by any available means. And vegetables grown in such a greenhouse will seem twice as tasty!
How to properly organize the space inside the greenhouse for cucumbers: photo
No matter if you made a minido-it-yourself greenhouse for cucumbers or have built a full-fledged greenhouse, it is very important to rationally use the space available inside. As a rule, the dimensions of the arches for the greenhouse or other elements that make up the frame are selected taking into account the fact that in the future you will need to take care of the plants. Here are some guidelines to help you organize the space inside the greenhouse for cucumbers:
- for small-sized structures, the ideal scheme for planting cucumbers in a greenhouse will be to divide the space into two equal parts, where there will be beds on the sides, and a path will pass in the middle
In a small greenhouse, it is convenient to plant cucumbers in two rows with a passage between them.
- so that the beds have clearly defined boundaries, think over a fence for them. It may be small, but should clearly delineate landing areas and aisles.
- be sure to treat all materials that are used to decorate the space inside the greenhouse with a special protective agent. This will prevent moisture decay.
- attention is also required to the soil, which is in the greenhouse, and in which you will plant cucumbers. Its humidity should not be excessively high, especially in the cold season.
You should also take care of the quality and moisture level of the soil in the greenhouse.
- high humidity in the greenhouse is a prerequisite for good plant growth, therefore all materials that you plan to use for the design of paths and fences must be resistant to moisture and temperature.
Accurately adhering to the recommendations on how to do it yourself greenhouse for cucumbers many troubleshooting problems can be avoided in the future. Thus, saving time and effort to eliminate errors.
The choice of window frames and other materials for the greenhouse, tips
The choice of material from which the frames are made is not so great. For this purpose, glazed frames made of wood, metal and plastic can be used.
Wooden window frames
Wooden frames are the most common building material, as they were the only ones used in the construction of houses in the past decades. It will not be difficult to purchase the required amount: plastic windows are becoming more and more popular and you can often see discarded wooden frames, even with whole glass, near landfills. In addition, it is worth asking neighbors or acquaintances - maybe one of them also decided to change the windows or re-equip the balcony.
A simple but original structure can be built from wooden frames.
Window frames made of this material are convenient due to their price and ease of installation. However, after 2-3 years, the wood in some places may rot or dry out. This will lead to the appearance of cracks and gaps that facilitate the penetration of cold air into the greenhouse. To prevent this, it is necessary to check the structure for the indicated defects every season. Since a warm and humid microclimate prevails inside the greenhouse, the paint on the frames peels off after each season. In this regard, the glazed frame must be tinted.
Frames should be tinted periodically
The service life of a wooden glazed structure ranges from 5 to 7 years. A greenhouse made of wooden frames can last longer, but due to external weather conditions and the characteristics of the internal microclimate, it can crack, losing its geometric shape... This will lead to a reduction in the greenhouse effect inside the building.
Wood window frames are susceptible to wood-borne insects.
Despite these nuances, wood remains the most affordable and popular material for building greenhouses and greenhouses.
The availability of the material allows the construction of greenhouses of various sizes and designs

Window frames made of this material are rare due to the high cost of metal. As a rule, such structures are made individually for each building. In this regard, it is difficult to find them thrown away in the form of construction waste.
If metal frames are installed, the greenhouse will retain its integrity and will not lose its shape for 25-30 years. The only enemy for this material is corrosion. It is more expedient to install metal frames on a frame made of a similar material. In this case, the window frames are welded to the supporting structure to form watertight seams.
The greenhouse in finished form is heavy. Therefore, the structure requires the installation of a capital foundation in the form of a strip or pile foundation. Sealing of such frames is carried out using polyurethane foam and bitumen sealants.
Metal frames are rare, but they can also be used to build a greenhouse.
It is more convenient to use sheets of cellular polycarbonate as a roof covering. The main criterion for installing this material instead of glass is the ability to withstand hail blows, the weight of snow, and also let in a sufficient amount of sunlight inside the greenhouse.
Plastic bags as sections for a greenhouse
If you are lucky enough to purchase plastic bags for building a greenhouse, then you can be sure that the finished structure will be reliably protected from external influences. Thanks to several chambers of the bags, additional barriers are created for the penetration of cold air currents.
It is more convenient to use plastic as the main frame for the installation of metal-plastic sections. However, the use of wood is acceptable with appropriate processing.
Metal-plastic structures allow you to create an aesthetic structure that will decorate the site
The finished greenhouse made of metal-plastic sections has a neat appearance and will not lose its aesthetic properties after several decades. This is due to the fact that polymer compounds in plastic are not subject to decay, corrosion or the negative effects of ultraviolet rays. In addition, plastic is not a suitable environment for the life of wood-boring insects and rodents.
Double-glazed windows can be installed instead of roofing material. These glazed sections withstand the impact of hail.
The walls and roof of the greenhouse can be built from metal-plastic bags.
Such a structure is heavy, therefore, like the previous options, it requires laying a concrete base.
The choice of materials for the foundation
Since the frame structure of the greenhouse with each of the indicated materials must be installed on a solid foundation, attention should be paid to the foundation material. The following are used as the basis for the frame of the greenhouse:
- a rock
Due to the large weight of the greenhouse structure, as well as the fragility and low resistance to external influences, it is impractical to make a base from wood. The close location to the ground contributes to the fact that after one or two seasons, such a base will be covered with cracks, deform or begin to rot.
The use of bricks for this purpose is more justified. The use of red bricks will make a solid foundation. However, this material tends to deteriorate under the influence of moisture and temperature fluctuations. White silicate brick is more effective for this case. This material is stronger than red clay brick. Such a foundation will retain its original state for decades. The only drawback of white brick is its cost.
It is better to use white sand-lime brick for the foundation.
A stone foundation is the strongest and most expensive foundation, therefore it is more profitable to purchase this building material near its deposits. Thanks to its natural strength, the stone foundation can be considered eternal.
Using concrete as a foundation is the most popular option. This material is cheaper than brick and stone, and in terms of strength and durability it is not inferior to a base made of white silicate bricks. The concrete base is negatively affected by strong freezing of the soil, because of which it swells, damaging the foundation.
Concrete foundation is the most common foundation for a greenhouse

Installation of a wooden greenhouse with a film coating
Along with greenhouses made from scrap materials, a house-shaped structure can be presented as a common version of a cheap greenhouse. In this case, wooden boards, beams or metal pipes are taken as a basis, and the coating function is performed by a film or membrane known to all.
A greenhouse 3 × 4 m can be built with the following materials:
- Planks, beams or steel pipes - 150 m. They are cut into several pieces for vertical posts - 1.5 mx 30 pieces, horizontal lintels - 1 mx 110 pieces. From the rest, braces and door leaves are mounted.
- Film or membrane: on the walls - 35.5 m 2, which is 1.5 × 24 m on a roll; on the roof - 24 m 2 - this is 1.5 × 16 m.
The roof can be closed not only with a film material, but also with cellular polycarbonate, then, according to the parameters specified above, it will need 4 sheets of 1.2 × 5 m in size.When installing the gables, an additional 8 m 2 of cover will be required, and this is a 1.5 × 5 film, 5 m or polycarbonate 2 sheets 1.3 × 3 m.
We plant tomato seedlings
The quality of the seedlings is the key to success in obtaining a good tomato harvest.
ATTENTION! Sowing is carried out in the first decade of March. For sowing, prepare boxes, fill them with a steam-sterilized soil mixture
A special ready-made mixture for tomatoes is suitable
For sowing, prepare boxes, fill them with steam-sterilized soil mixture. A special ready-made mixture for tomatoes will do.
Or a substrate of four parts of sod land and two parts of sand.
To increase the nutritional value, a little wood ash is added to the mixture (a 10 liter glass).
It is better to germinate the seeds in a moist tissue before sowing. After 4-5 days, they will swell and can be placed in the ground. The seeds should be arranged tightly enough, since there is no guarantee that all of them will sprout. Spread the seeds over the surface, sprinkle them with a 1.5-2 cm layer of soil, cover the box with foil. Germination should be carried out at a temperature of 22-25 degrees, in a bright place.
IMPORTANT! Make sure that the rays of the sun do not fall on the box, otherwise the seeds will simply cook, and you will not wait for germination. As soon as the first shoots appear, the film should be removed, and the temperature should be reduced to 18-20 degrees so that the plants do not stretch out.
When the tomatoes have several real leaves, the seedlings dive at a distance of 8-10 cm from each other
As soon as the first shoots appear, the film should be removed, and the temperature should be reduced to 18-20 degrees so that the plants do not stretch out. When the tomatoes have several real leaves, the seedlings dive at a distance of 8-10 cm from each other.
The predecessors of tomatoes on the site can be carrots, onions, cucumbers, zucchini.
IMPORTANT! You cannot plant them in the place where potatoes and peppers grew. It is also not recommended to plant tomatoes in the same place where they grew in the previous season.
The soil at this place is depleted, as the tomatoes that grew there pulled out the necessary minerals
It is also not recommended to plant tomatoes in the same place where they grew in the previous season. The soil at this place is depleted, as the tomatoes growing there have drawn out the necessary minerals.
If your greenhouse is portable, consider this condition. In a stationary greenhouse, the soil must be replaced. The soil should be loose, with a sufficient amount of sand or peat. It is also necessary to add well-rotted humus. But don't add too much of it, it will lead to overgrowth of the leaves.
IMPORTANT! Do not fertilize tomato beds with fresh manure. The roots from this will burn, and the fruits will not be tied.
It is also necessary to observe the acidity of the soil; dolomite flour or slaked lime is used to reduce it.
It is also necessary to observe the acidity of the soil; dolomite flour or slaked lime is used to reduce it.
We plant seedlings
Before placing tomato seedlings in a permanent place in a greenhouse, they should be hardened, accustomed to the sun.
If you transplant unprepared plants into the ground, they will start to hurt, burn under the sun, and may even die.
The hardening process begins even in cold weather, with the help of open vents.
You can take out the boxes with seedlings to the balcony so that it gets used to the low temperature. In addition, before planting in the ground, it is necessary to reduce the frequency of watering the seedlings.
With the onset of warm days, take the boxes with seedlings outside and place them in a place protected from wind and sun. Keep the seedlings out of the sun, especially in the first week. Before planting, put the boxes in the greenhouse for two to three days so that the plants get used to its conditions. The film or frames need to be slightly opened during the day.
As soon as the threat of frost passes, the tomatoes are planted in the greenhouse. This usually happens in mid-May.
ATTENTION! If a sudden cold snap suddenly occurs, the greenhouse is additionally covered with a layer of non-woven material or any fabrics. Tomato bushes are planted at a distance of 35-40 cm from each other, row spacing - 50-60 cm
If the bushes are stretched out, you can plant them at an angle, with the crown on the north side. Having taken root, the bush will rise to the south, and form a powerful root system
Tomato bushes are planted at a distance of 35-40 cm from each other, the row spacing is 50-60 cm. If the bushes are stretched out, you can plant them at an angle, placing the crown on the north side. Having taken root, the bush will rise to the south and form a powerful root system.
After planting tomatoes in a greenhouse, they are watered and the ground is mulched so that a crust does not form. A week after planting, the plants are treated with a late blight preparation.
