- The protective layer on which the inscriptions are applied must be located with outside greenhouse
- To get the maximum robust construction be sure (!) to pay attention to the location of the polycarbonate “honeycombs” - they should only go vertically, in inclined structures - parallel to the slope.
- When creating arches, keep in mind that polycarbonate sheets bend only in one direction - lengthwise, that is, along the line of the stiffeners.
- The joints of the sheets should be at the center of the frame post; the sheets are connected only in this way.
- This type of plastic is cut construction knife, jigsaw, grinder. You can also use a hacksaw or a circular saw.
- To firmly connect the sheets to each other, special plastic profiles. Manufacturers do not recommend overlapping polycarbonate. In practice, when making a polycarbonate greenhouse with your own hands, it is not always possible to cut and fit the sheets perfectly. Some craftsmen even manage to do without connecting profiles, placing polycarbonate overlapping. The most important thing is that the joint must be in the center of the rack, and not sag in the air. Moreover, even with ideal installation, snow pressure can force the sheet out of the profile. In the case of overlap, this does not happen.
- It is not advisable to use a powerful drill for screwing in self-tapping screws - it will overtighten the fasteners and often slip off during operation. It is better to work with a regular screwdriver. Polycarbonate is drilled at low speeds with little effort. Next, turn off the tool, insert the screws and continue working.
- The distance between the screws to be screwed in is 25-70 cm. It all depends on the type of frame and the expected snow and wind load.
- When assembling polycarbonate structures, rivets are sometimes used instead of self-tapping screws. However, dismantling the greenhouse or replacing a damaged sheet in this case will be more difficult.
- When the temperature changes, plastic can change size. When making butt joints between the sheets, be sure to leave small space a couple of millimeters in size - technological gap. Otherwise, cracks will form at the junction. For the same reason, the size of the holes for fasteners is made a little larger. To prevent the plastic from cracking, do not tighten them all the way.
- To compensate for expansion and protect against cold bridges, it is recommended to use special thermal washers for polycarbonate (screws are purchased separately). Allowed to use roofing screws EPDM, equipped with a gasket or standard for metal with a rubber thermal washer, in which the threads have a small pitch.
Obvious:
- low cost;
- ease of installation;
- mobility of the structure;
- the ability to install buildings of any configuration;
- durability due to resistance to unfavorable conditions. Such greenhouses, when properly assembled, last no less than 15 years;
- environmental friendliness. PVC does not emit toxic substances. They are easy to clean, which means they will not accumulate mold and mildew that can infect plants.

Preparatory activities
Before you start construction greenhouses, you need to decide on the type of structure, make a list of materials and calculate the cost.
Greenhouse from PVC pipes can be arched, rectangular with pitched roof, rectangular with an arch at the top and a combination of sections. For such structures, the optimal dimensions are 2-2.4 meters height, 3m. width and length from 4 to 12 meters. Specific dimensions are selected depending on the purpose and installation location on the site.
Pipes with a diameter of 25-32 mm for arched structures, 50 and more mm for rectangular racks. To connect pipe sections, special cross angles are used, which can be purchased at any plumbing store.
By quality of material PVC pipes are divided into two types:
- Hard– used for straight structures in the form of pitched houses.
- Flexible– used for arched, hemispherical and spherical greenhouses. It is convenient to use such pipes for superstructure arched roof made of wood or metal.
IMPORTANT! The design must be selected with a minimum amount docking ports, since they significantly weaken stability.
For installation tools needed:
- hacksaw for wood and metal;
- hammer;
- building level;
- screwdriver;
- machine for welding pipes (for the manufacture of non-demountable structures).

Site selection and site preparation
To install a greenhouse from PVC With your own hands, you need to choose the right place, taking into account the lighting, soil quality, and wind direction. There should be a convenient approach to the construction. The optimal orientation to the cardinal points will be west-east longitudinal direction.
Turf is removed from the selected area according to the size of the future greenhouse with a small margin of about 50 cm in width and length. The resulting area is leveled horizontally. The height difference is permissible no more than 5-6 centimeters. All recesses must be filled and leveled.
Structures can be collapsible or non-demountable. Pipes can be left on winter on site, as they are not afraid of temperature changes. The film is most often removed for the winter. Polycarbonate can be left over the winter with proper preparation and care during snowfalls.
Preparing the base
Greenhouse from PVC pipes light, so the capital foundation for it not needed. At the same time, the presence of a frame will give strength to the frame and maintain its shape during operation. Let's consider options for preparing the foundation for various types designs:
- Wooden frame. It is most appropriate to use it for an arched greenhouse, but it is also suitable for building in the form of a house. To make a frame you need to prepare following materials: boards 1.5-3 mm thick or bars 6Х12, 8Х12. A rectangular frame is knocked down or twisted using self-tapping screws from the prepared material. Using a tape measure, check the diagonal of the frame to avoid misalignment of the sides. Fix the manufactured frame with pieces of reinforcement on the soil so that it does not move around the site. The pins are driven into the corners inside the frame.
- Metal pins. You can attach the pipes to pieces of metal reinforcement driven directly into the soil. This design will be lighter compared to a greenhouse on a wooden base. For such a foundation, along the length of the future structure, they are driven in on both sides. metal rods 70-80 cm long. The pins are driven into the ground half the length at a distance of 50 cm from each other.
- Metal frame from pipes with pins welded to them or a base assembled from the same PVC pipes. Such a base can only be made by using welding machine. Its advantage is maximum mobility structures. The frame together with the frame can be easily moved to any place on the site. Alternatively, instead of a frame, you can make two pipes equal to the length of the greenhouse tunnel and weld pins to them. Such pipes are laid on the ground and fixed with metal slingshots. In this case, at your discretion, you can change the width of the greenhouse depending on the installed pipes.
IMPORTANT! The wooden frame must be treated antiseptic so that fungus does not develop on it. If this is not done, the frame will last one year and will be unusable by the next season.
Greenhouse diagram - polyvinyl chloride frame: 
Manufacturing technology of various designs
Depending on the chosen type of construction from pipes the required amount of material for the base is prepared, fasteners are prepared and material for the coating is selected.
Frame and cover
How to make a greenhouse from PVC pipes and polycarbonate with your own hands? To make a greenhouse in the form of an arched tunnel, pipes of the required length are cut. The pipes are easily bent and attached to the base of the greenhouse. The pipes bent into an arc must be secured along the entire length of the frame.
For fastenings there are two options:
- Mounts directly to frame. To do this, the pipe is fixed on the surface of the board using metal fastenings for plumbing equipment.
- As an option along the length of the greenhouse driven into the ground metal pins close to the frame. The pitch between the pins is no more than 50-60 centimeters. Pipes are strung on them.
Along the length of the tunnel must be fixed stiffener. To make it, a pipe is taken with a length equal to the length of the tunnel. This pipe is secured with plastic ties at the top of the arches from inside the structure. If the structure is long and wide, you can attach stiffening ribs to the side walls, this will increase durability And greenhouse strength.
The next step will be manufacturing ends. It can be made in the form of frames from wooden blocks or in the form of a plywood semicircle with holes for entering the greenhouse. It is advisable to provide ventilation vents in the end coverings. Pediments can also be assembled from pipes.
To do this, using plastic turning angles and tees, it is assembled plastic frame along the height of the greenhouse.
The length of the transverse pipes is equal to the width of the doorway.
To ensure the strength of the ends, vertical pipes are additionally installed on both sides of the opening.
To the greenhouse frame PVC pipes are fastened using tees placed on the outer arches.
Prepared frame for a greenhouse from PVC pipes covered with plastic film or polycarbonate sheets. The film used for such structures is thick and reinforced. The coating is attached directly to the pipes using self-tapping screws.
To prevent the resulting holes from tearing the film, tapes of linoleum.
The film can be thrown over the greenhouse and secured with ropes, mesh, or double-sided tape. If a polycarbonate covering is selected, self-tapping screws along the bottom edge are attached to wooden frame using wooden slats. The film must be attached with maximum tension, otherwise it will sag and tear during operation.
REFERENCE: To ensure uniform coverage, film attachment begins with center of the structure with gradual tension towards the ends.
It is advisable to attach the film to the end frame using construction stapler . The entire frame is covered with film. The door is assembled separately and placed on hinges. A frame door with hinges is also needed for plywood ends. You can use wooden frames from old windows as a door. But instead of glass, it is better to stretch the film or cover the frame with polycarbonate sheets. Glass for greenhouses from PVC pipes It is not used at all, as it has a lot of weight.
Along the bottom edge of the film should lie on the ground, so the margin on each edge should be at least 15-20 cm. Bottom edge of the film sprinkled soil.
Polycarbonate It is more expedient to cover the arcs along the entire length, joining the sheets at the locations of the pipes. The joints are taped with tape or neutral silicone sealant. Frame covered polycarbonate, is non-separable, therefore in winter period The greenhouse must be regularly cleared of snow. Additionally, reinforcing supports must be installed under the arches so that the structure does not collapse in winter under the weight of snow.
For the ends, a frame is made of pipes or wooden slats and sheathed with pieces of polycarbonate. The strength of the frames is ensured by diagonal slats or pipes. Doors And windows are placed on hinges.
Pitched in the form of a house
According to reviews from experienced vegetable growers, greatest strength has gable frame greenhouses made of PVC pipes. This frame is most suitable for a non-demountable greenhouse covered with polycarbonate. Gable roof Snow loads are not scary, so such a greenhouse does not need to be cleared of snow in winter.
The process begins with the manufacture of a wooden frame required size. Installed on long sides pins as described previously.
Straight pieces of pipes of the required height are put on them.
Alternatively, it is possible to install vertical pipes on pins driven into the ground. The length of the pins is 80 centimeters.
They are driven into the soil 40 centimeters along the long sides. Put on the pins pipes.
Special ones are put on the top of the pipes tees, are attached to the corner pipes crosses. Next, the roof of the house is assembled using pipe sections of the required length.
This design is best covered polycarbonate. It is attached using roofing screws with thermal washers. Polycarbonate is cut into pieces for the side walls and roof separately. The joints are sealed with special tape for polycarbonate greenhouses or construction tape.
ADVICE: It is better to purchase pipes and fastenings to them from ready set so that everything will definitely fit in diameter to each other.
Rectangular with arched roof
For the manufacture of frame In such a greenhouse, pipes are installed in the same way as in a pitched greenhouse in the form of a house. Using tees at the top they are attached bent in an arc pipes. This design is easier to assemble compared to a pitched one. A stiffening rib is laid in the center of the arched roof.
You can use them as stiffening ribs in the side and top parts of any greenhouses. wooden slats , treated with an antiseptic.
Greenhouse from PVC pipes has a much lower cost compared to stationary polycarbonate structures. With some effort, you can easily build it yourself.

Any summer resident can build a greenhouse on his plot - just make simple calculations, prepare necessary materials and free yourself for one or two days from other activities in order to calmly and without haste begin construction. Small greenhouse from plastic pipes It is built with your own hands very quickly and simply, requiring very little effort and financial investment. The reward for your time will be the opportunity to practically all year round enjoy your organic vegetables.
Arched greenhouse made of pipes and film
According to its quality and operational characteristics plastic structures are not inferior, and in some ways even superior to wooden and metal ones. Plastic pipes are not subject to rotting, like wood, and corrosion, like metal. They are light and at the same time durable, do not weigh down the structure and do not require the installation of a complex foundation, and at the same time withstand heavy loads. Service life exceeds ten years.
Plastic is a flexible material and bends well, which allows you to independently special effort give it the desired configuration. Thanks to this, it is not at all difficult to realize any form of a greenhouse made of plastic pipes with your own hands, for example, in the form of an arch, in the form of a house with a gable or pitched roof and even a complex geometric design.
Pipe greenhouse with gable roof
Preparatory stage of construction
Before you make a greenhouse with your own hands from plastic pipes, you need to prepare its drawing and make calculations about how much and what material will be needed for construction. This will help you avoid buying excess.
Where is the best place to put a greenhouse?
This is far from an idle question, since not only how the planted plants will develop depends on the installation location, but also the amount of crop grown. For a greenhouse made of plastic pipes, it is advisable to choose an open and sunny plot, on which there is no shadow from trees and country buildings.
With a lack of natural light vegetable crops will grow slowly and develop poorly, which will require additional lighting.
It is best to place the greenhouse from east to west. In this case, it creates optimal conditions for plants, since it will be illuminated throughout the daylight hours.
Construction plan and calculation of the amount of material required
It is quite difficult for a non-professional to make a design drawing on their own. But this is not a problem, today you can find a lot finished projects, and based on them make the necessary calculations. Below is a drawing of the greenhouse arched type. Based on it, it is easy to make an approximate calculation of the material that will be needed to build a greenhouse.
Scheme of a greenhouse made of pipes in the form of an arch
So, a greenhouse made of plastic pipes has a length of 6 m, a width of 3 m and a height of 2 m. For production you will need:
- fifteen plastic pipes 6 m long for the arch, screed, two gables and additional elements;
- boards or timber 6 m long for the base and thin wooden planks for securing the film;
- crosses and tees for connecting pipes;
- polyethylene film for greenhouses 6 m wide – 36 m2;
- fittings 0.75 m long - 24 pieces;
- screws, nails, angles, staples, plastic clamps, door hinges, hinges and handles.
In the above drawing, one pipe located in the center is used as a tie; however, to strengthen the structure, it is better to make the same tie on the sides of the greenhouse. Front doors You can install it only on one side, and make a blank wall with a window on the other.
When calculating the total length of the pipes, add 10% for any unforeseen cases.
Requirements for basic materials
There are plastic pipes different types, for greenhouses it is advisable to choose polypropylene or made from polyvinyl chloride (PVC). They are resistant to frost and do not deteriorate from exposure high temperatures and withstands changes well temperature conditions. Pipes with an internal diameter from 13 to 25 mm are suitable for the greenhouse.
Since building a greenhouse from plastic pipes with your own hands does not require installing a foundation, wooden boards with a thickness of 20 to 40 mm or timber with a cross-section of 30x30 mm are suitable for arranging the base. If you plan to use film as a coating, then it is better to choose reinforced film with a density of 120 to 200 g/m2.
Reinforced film for greenhouse covering
A cheaper option is textile material such as “agrotex”, but it has a low degree of thermal insulation. Polycarbonate is considered the most durable and durable coating, but in this case the cost of the structure will increase significantly. Sheets with a thickness of 4 to 8 mm are suitable for the greenhouse.
How to prepare a site for future construction
To install a greenhouse made of plastic pipes, you need flat area without bumps, holes and other irregularities - before building the foundation, it is necessary to prepare the site. To do this, you need to remove a small layer of soil one meter wider and longer than the future structure.
To make the structure more stable and durable, dig a trench around the perimeter. Its depth and width depend on the size of the board or beam, which should be half buried in the ground. Fill the bottom with crushed stone, and then lay roofing felt.
You can check how level the area is using a building level; if necessary, level the surface. The height difference should not exceed 5 cm. If there is a significant slope on the site, then the platform for the greenhouse can be leveled using boards, as shown in the photo.
Installing a greenhouse on a site with a large slope
Main stages of greenhouse construction
After all the calculations have been made, the necessary materials have been purchased, and the preparatory work, you can begin to construct the structure.
How to make a base for a greenhouse
Wooden boards are used to make the base of a home greenhouse. It is advisable to first clean them with a plane or sand them with sandpaper. It should also be noted that untreated wood special compounds may rot over time. Therefore, be sure to cover it with protective antiseptic preparations that prevent rotting processes.
Wooden base
The wooden frame is assembled directly on the site prepared for the greenhouse. The boards are secured to each other using galvanized screws or nails. If beams are used for the base, then they are connected without metal elements using the half-tree cutting method.
Then the frame is installed in the trench and tightly covered with earth so that there are no cracks or gaps left. To strengthen wooden foundation It is recommended to additionally fasten the internal joints of the boards with steel corners.
To check the accuracy of the design, measure its diagonals; their lengths should be equal. To fix the frame, reinforcement is driven into each corner.
The protruding part of the metal rods must correspond to the height of the base. From outside or inside long boards, reinforcement is also hammered in increments of 67 cm, which should protrude 40 cm above the surface. The rods should be positioned clearly opposite each other.
Fastening boards from the inside
Making a frame from plastic pipes
There are several options for installing the frame. One of them:
- Take a plastic pipe and place one end of it on a metal pin driven into the ground.
- Fasten the other edge to the opposite rod. You should now have an arc.
- For strength, screw them on both sides to wooden base metal staples.
Another option is to make a greenhouse from plastic pipes with your own hands, as shown in the photo.
Greenhouse with lower horizontal bar
For this:
- Cut the pipe into pieces 40-50 cm long.
- Place them on the reinforcement, and then use plastic crosses to connect them to the horizontal guides and the main arcs. Thus, a pipe will pass through the lower part of the greenhouse, which, on the one hand, will add strength to the frame, and on the other, will increase its height.
- Next, you need to install horizontal ties in the center and sides of the structure. It is recommended to make them from rigid PVC pipes. They are attached to the main arched skeleton using plastic clamps.
- To strengthen the frame, it is advisable to install wooden beam or a hard plastic pipe. One end of it needs to be buried in the ground, and the other must be supported by the arched structure.
How to install greenhouse ends
Door structures can be made from pipes or wooden planks. For convenience, it is better to assemble the doors separately, and then ready block install on the front of the greenhouse.
You will need four plastic pipes. Two of them should have a length equal to the height of the door, the other two for the opening should be 10-15 cm higher. Also prepare three cross bars 80 cm wide and one 10 cm wider.
Door assembly drawing
- Assemble the doors and opening using plastic corners and tees, as shown in the diagram above.
- To strengthen the door, you can also lay a diagonal strip from the middle to the bottom line.
- Place two tees on the outer arched arch at a distance equal to the width of the opening, and secure the door block to it.
- If you want to make a window in a greenhouse from plastic pipes, the opening for its installation can be assembled according to the previous diagram. The photo below shows how the window is assembled.
- Before installing the openings into the main structure, wrap them plastic film, which can be secured to pipes using self-tapping screws or double-sided tape.
Assembly diagram of a blind opening with a window
How to cover a frame with film
- Distribute the plastic film over the entire greenhouse structure so that there is an even supply on both sides.
- Then, fixing the film with planks, nail it to the wooden frame. First fasten one side, moving from the center to the corners, then stretch the material well and also nail the opposite side.
- Lastly, take care of the blind ends of the greenhouse. To secure the film instead of planks, you can use a furniture stapler.
To prevent the film from blowing up in the wind and to fit more tightly to the frame, it is recommended to additionally secure it to the pipes. This is especially true in cases where the greenhouse is covered with ordinary rather than reinforced film. To do this, you can use special clips, a piece of flexible hose, or a small piece of the same plastic pipe, cut lengthwise. Pipe clamps and office clips hold the film well.
Possible options for attaching the film to the frame
Covering the greenhouse with polycarbonate
Covering the greenhouse should start from the end parts. After assembling the openings, take the necessary measurements, lay the polycarbonate on a flat surface and cut pieces of the required sizes with a small margin. Sheets can only be installed in a vertical position, keep this in mind when taking measurements.
First, the end parts of the structure are coated
- Remove protective film from the inside of the material and screw it using special roofing screws with thermal washers to door block, vents and blind parts of the ends of the greenhouse. You should twist it very carefully so as not to damage the material. Cut off the excess polycarbonate with a knife.
- To cover the rest arched design Screw the polycarbonate to the wooden base on one side.
- Then carefully lift the sheet up and at the same time tighten the screws on the plastic pipes every 60-70 cm.
- On the opposite side of the greenhouse, also fix the covering to the wooden frame.
- The next sheet of polycarbonate is laid overlapping the previous one and fixed with self-tapping screws.
Installation of polycarbonate sheets
You can learn more about how to assemble a greenhouse from plastic pipes with your own hands in the video.
To make a greenhouse from plastic pipes with your own hands, it is not necessary to have special skills or be professional builder. Having all the necessary materials available, you can build a shelter in just one or two days.
By making a greenhouse at your dacha yourself, you will not only save money, but also get a reason to invite your friends to appreciate your work. And most importantly, from early spring until late autumn you will have vegetables grown at home on your table.
It’s quite difficult to build or purchase a stationary expensive greenhouse, but to build it yourself inexpensive greenhouse from PVC pipes is quite possible. Let's see how this can be done so that you can plant early seedlings in your garden.
Greenhouse made of PVC pipes: its advantages and disadvantages
The design of a greenhouse made of PVC pipes is quite simple and consists of a foundation, polyvinyl chloride pipes, fastening and special connecting elements, as well as a certain coverage.
Such a greenhouse has many advantages:
- Does not require special skills and qualifications for its installation, and complex equipment and expensive instruments;
- It has high level durability and can last even two or three years without dismantling;
- If necessary, the greenhouse can be removed in one day;
- It is not subject to decomposition and tolerates high levels of humidity, unlike greenhouses made from old window frames.
Disadvantages of a greenhouse:
- Short service life of film polyethylene coating;
- Low level of thermal insulation of polyethylene.
But these problems can be easily solved using cellular polycarbonate, but this is a more expensive coating.
Attention! In regions where there is frequent precipitation, which falls in the form of a thick and dense snow cover, there is a high risk that a greenhouse made of PVC pipes may collapse under the weight of wet snow. Therefore, when carrying out calculations, it is necessary to provide a large margin of safety.
Fully assembled PVC pipe greenhouse
Preparation for construction: drawings, dimensions
Before you start installing a greenhouse, you need to choose the most convenient place for it, level it and make sure that the soil does not sag under the weight of the greenhouse.
If you use polyethylene film to cover the frame, then the dimensions can be taken arbitrary. We will look at an example with a size of 3.82x6.3 meters. Why exactly these sizes, you ask?
The pitch length between the pipes in the frame will be 900 mm, so with 8 sections we will have 7 spans. And if we multiply 7 spans by 900 mm, we get a greenhouse length of 6.3 meters.
drawing of the greenhouse frame indicating the span length
You can choose other sizes depending on how large the greenhouse you want to build, but remember that what more design, the less stable and durable it is.
Pipes and other materials can be purchased at the store. But when choosing PVC pipes, you must choose very carefully, since they can vary greatly in quality. You should not buy cheap low-quality pipes.
Since the frame is built from engineering PVC pipes, it is recommended to take the material that is used for connecting hot water and easily connects to plastic crosspieces. Wall thickness 4.2 mm, internal diameter 16.6 mm, external 25 mm.
The pipe connection elements must be taken from high-quality thermoset plastic (wall thickness 3 mm).
Since the entire frame of the greenhouse is, as it were, “dressed” on special pins driven into the ground, they must be selected in accordance with the diameter of the pipe itself, so that it “sits” tightly on such a pin and does not “dangle” on it. This will ensure the strength and stability of the entire structure, and there will be no need for additional fastening.
Their length should not be less than 0.5 meters, and we recommend going deeper into the ground at least 15 centimeters.
Material calculation and necessary tools
To build a greenhouse from polyvinyl chloride pipes, you need to have a certain amount of material and some tools.
Greenhouse materials:
- PVC pipes (Ø25 mm) – 10 pieces;
- Cross and tees (Ø 25 mm);
- Special oblique tees;
- Packaging of screws and nails;
- Thin iron strip;
- Iron rod;
- Board (size 50x100 mm);
Tools:
- Hammer and hacksaw for metal;
- Screwdriver (or Phillips screwdriver);
- Bulgarian;
- Welding iron for pipes;
- Construction level and tape measure.
Step-by-step instructions for building a greenhouse with your own hands
- We assemble the frame of our greenhouse from the board. To do this, before installing wooden board need to be well soaked with an antibacterial substance. We install the base on the selected area, observing all geometric shapes. To do this, you need to cut four rods 50 centimeters long from an iron rod and drive them into the four corners of the base from the inside, strictly adhering to the diagonal.
Construction of a wooden base for the future frame
- We install a special mount for installing frame arches. To do this, you need to cut 14 identical pieces of reinforcement 70 cm long. Next, along the entire length of the base, we make markings with a marker at intervals of 900 mm. Then, following the knocked-off marks from the outside, we firmly drive in the reinforcement approximately 40 centimeters. It is necessary to drive clearly close to wooden base. Next, you need to make markings along the width of the base and to do this, divide the frame into two equal parts. Then, stepping back 40 cm from both sides, make marks. We also hammer in the reinforcement according to the marks.
Installation of reinforcement for a greenhouse frame made of PVC pipes
- We make arcs. To do this, you need to weld two pieces of pipe 3 meters each together with a special welding “iron” so that they have a cross in the very middle. We made the internal arches, but the external ones are made a little differently. In the center, the pipes are welded with straight tees.
Welding arcs using a cross
- Installation of arcs. To do this, they must be inserted into pre-hammered reinforcement on one side and the other. PVC pipes bend without problems. Thus, we get the frame of the future greenhouse over a wooden base.
Installation of PVC pipe arcs
- Next, you need to install a special stiffening rib in the center of the structure. To do this, we precisely cut the pipe into 850 mm pieces and then weld it well between the tees and crosses. With these actions we strengthen the strength of the frame. Then we secure it to a wooden base using a metal strip, a screwdriver and self-tapping screws.
- We make a door and ventilation window. Since the structure is complete, it is necessary to decide where the door and window for ventilation will be located. Where we installed two rods at width, this is where the door will be located. To do this, measure a straight line up with a level and mark it with a marker on the first pipe.
Door and window design for ventilation
- We marked two points on the same vertical with the reinforcement, and then we will cut the necessary oblique tees into this place. To do this, measure the distance from the bottom of the rod to the mark and, according to the data obtained, cut off the required piece of pipe. We weld a special tee to it, so that we get a structural part with a tee at the top. We join the bevel to the pipe.
- Now you need to cut the arc at the marked point, but very carefully, since it is under load. Then we weld the tee into the resulting space. But here you will need the help of one more person.
- After you have completely checked the frame for strength, you need to stretch plastic film over it. We take ordinary nails and wooden slats. We nail the film well along the entire length, first on one side of the base, and then, after stretching it well, we throw it over to the opposite side and also nail it on the other side.
We nail the plastic film to the wooden base of the greenhouse using nails and slats
- The door and ventilation window can also be easily made from the remains of a pipe. To do this, we make two square pipe structures, according to the dimensions you made before. We weld the pipes with an iron using corners. We also weld special latches to the door, which will hold the removable door. We also make a window.

If you do not want to attach cheap and low-quality film, then you can use more modern and durable films such as lutrasil, agrospan, agrotex and others. Also a great option can be reinforced and special bubble film. Durable 11mm reinforced film can withstand strong winds, sleet and hail.
Reinforced film for greenhouses
The film is cut sharp knife. You should always cut a piece for the frame with a margin. This is necessary in order to then tuck it in and nail it using a wooden plank.
It is best to then line the lower end with bricks or stones and cover it with soil to protect the seedlings from being blown by the wind.
The service life of polyvinyl chloride pipes is about 50 years, but since they will stand outdoors under the harmful effects of UV rays from the sun, wind, rain, snow and others precipitation, then they will last no more than 20 years, although this period is quite long.
Also today there is an excellent coating for a greenhouse (light-stabilized or aluminum-reinforced polypropylene). These types of coatings are not subject to thermal deformation and are resistant to solar radiation.
Light-stabilized film for greenhouses
In order for the greenhouse to last as long as possible, it is recommended to do concrete covering(foundation) and thereby also increase the strength of the structure. Then, during the off-season, the greenhouse is simply dismantled, but the foundation remains. This way, your seedling boxes will not sit on bare ground, but on a solid concrete base. There will also be no need to make a walking path in the middle of the greenhouse made of wood, which will also rot over time.

Such a simple, but very beautiful and durable greenhouse or greenhouse will delight its owners long years excellent seedlings or a harvest of early vegetables. And if you are a literate person and think about it good system lighting and heating, then this design will be indispensable for your entire family.
Our man traditionally likes to grow trees, vegetables and fruits on his summer cottage. But our weather and temperature vary, and some crops require early landings And long term ripening. This is where the need for greenhouses arises. Factory greenhouses - they can be capital and very light, arched and “house”, their glass and plastic are expensive and do not always fit the area in size and size. But there is always an opportunity to do the simplest greenhouse with your own hands - for example, from plastic pipes.
What is a greenhouse and how does it differ from a greenhouse?
Often these concepts are confused. These designs, of course, are similar in material and design - frames and transparent coating - plastic, film or glass. But a greenhouse is most often a place where you can stand and take care of beds or bushes, and important condition: it must be capital.
Greenhouses come in an endless variety of shapes and materials
To protect against cold, wind, and precipitation, greenhouses are covered with plastic film or plastic sheets.

Plastic sheets are usually cellular polycarbonate- used for stationary heavy greenhouses that are used throughout the year.

A greenhouse is a low, long shelter for a garden bed, often with a semicircular cross-section. As a rule, it is used for growing seedlings in the spring. Sometimes they are made on a wooden base and also stand stationary, on boxes of timber and boards.
A stationary greenhouse of this design is easier to make from metal pipes
And often they are placed directly on the ground above the garden bed. Then it’s easier to make them from plastic pipes so that they can be easily transported from place to place.

Advantages and disadvantages of plastic pipes for construction
A greenhouse has a lot of advantages and very few disadvantages.
Advantages
Affordability - such a greenhouse will cost less than all other analogues
Ease of assembly - such a greenhouse is easy to design and manufacture, and if it is not needed (for example, in winter), you can always disassemble it and store it somewhere.
Versatility - can be used in different places on the site.
Lightness - if necessary, it can be moved from place to place without even disassembling the structure.
Durability - plastic pipes are absolutely durable, not afraid of dampness, cold, heat, fumes, fungus, and rotting. The film or joints may become unusable (from frequent assembly and disassembly), but replacement will also be quite cheap.
Aesthetics - a greenhouse made of plastic pipes always looks bright and does not look like a homemade product made from scrap materials.
Safety - such a greenhouse is absolutely safe for plants and soil.

Flaws
All material must be purchased according to calculations. You won't be able to make do with improvised means.
Making a structure with your own hands
We present here two options for greenhouses - a very simple one for one bed and a more complex and tall one.
The simplest greenhouse
This is the most simple design greenhouse It just couldn't be simpler. Curved sections of pipe are dug in above the bed on both sides in increments of approximately 50 to 70 centimeters. The step depends on the thickness of the film used, and the number of segments depends on the length of the bed.
Let's say our bed is 6 meters long. This means that we will need 12 pieces of pipe with a length of one and a half meters. Since pipes are usually sold cut into 4 meter pieces, we will cut them into 2 meter lengths. This means there will be 6 pipes. Fittings (devices for connecting pipes) are not needed. Ideally, fasteners can be used, but you can also fix the film on the pipes by tying its ends into knots and pressing the edges with stones.
Film can be either primary or secondary processed. The latter is much cheaper, but usually either has an unpleasant brown, yellow or gray shade, or completely opaque - gray or black, so it will not suit us. The film is sold in a sleeve, so we will need to cut it lengthwise. We will choose a thin film with a thickness of 150 micrometers.
The film sleeve is sold in rolls of 10 meters

Making a simple greenhouse
- We cut the four-meter pipe in half. We get 12 pieces.
- We stick each piece one by one into the ground more firmly, knock it down and stick it on the other side of the bed. The bed turns out to be under an arc.
- We cut the roll of film lengthwise and cover the resulting structure with it so that there are identical “tails” along the edges.
- We fasten the film to the resulting arches with clamps - two or three per arch.
- We press the sides of the film to the ground with bricks or cobblestones.
- We tie the “tails” with twine - if desired, they can be untied to allow air to flow.
A greenhouse over a bed made of buried plastic pipes
Our greenhouse is ready. This is a primitive design, but it will fully perform all the functions required for a greenhouse.
Making a greenhouse of a more complex design
Greenhouse more complex design higher, longer, it covers a larger area of land and is suitable for more tall plants, has a door or two doors, sometimes vents, requires more pipes, complex elements of their connection system, more film fastenings to pipes (if film is used) or polycarbonate sheets (if polycarbonate is used). Can be used nonwovens- agrotex, agrospan, spunbond, possibly reinforced, which have much greater strength and can withstand strong winds and even hail. Even bubble wrap is used. They spend worse Sun rays, but retain heat much better.
Therefore, you should approach the choice of greenhouse model and, accordingly, the choice of material with special care.
Choosing a greenhouse model
We choose a design model of average complexity. Let it be a greenhouse made of pipes on a wooden frame (it’s easier this way, no need to concrete the rods). We find the drawing on the Internet and, if necessary, adjust it to the dimensions we need and our capabilities.
Drawing of a greenhouse with wooden parts includes all fastening elements
All nodes are visible in more detail in another drawing; this drawing suits us better; it does not require the presence of wooden planks. It can be seen that everything is very simple - our greenhouse is assembled like a children's construction set.
System of fastening pipes to each other and to the base
Material selection
The length of our greenhouse is about seven meters. According to the drawing, we select pipes. Of course, we will need a pipe of a larger diameter and with greater wall thickness than in the previous one simple version. We choose a pipe with a diameter of 25 millimeters.
A simple plastic pipe is the most budget option
The fasteners must match it. We need quite a few cross fittings of the appropriate diameter for the cross-shaped connection of the pipes.
The cross fitting will hold the pipes together perpendicularly
You will also need tees for the ends of the greenhouse.
We connect the pipes from the ends of the greenhouse with tees
The boards for the frame should also not be very thin, so we choose their thickness of 25 millimeters.
The edged board will serve as the base of the greenhouse
Cups for securing pipes are difficult to find, so you can purchase regular external plugs.
The plug can also serve as a glass
It is better to choose not ordinary polyethylene film, but heat-resistant reinforced one - so that it can withstand serious atmospheric conditions - heavy rains, hail, wind, which often happen in our summer.

Step-by-step process for making a greenhouse
- We choose a place. There must be good access, sunny, close to the water, level.

- We install a frame for panic from boards. We cut them into pieces of the required length and connect them with self-tapping screws. You can strengthen the connections with large steel angles. We carefully treat it with anti-rotting impregnation.
The greenhouse base made from boards is easy to assemble
- We attach plugs to the boards in the marked places with self-tapping screws - they will serve as glasses for the pipes.
Plugs will serve as glasses for pipes
- We cut the pipes into sections of the required length for arcs and horizontal sections.
- We insert the sections that should be the lowest into the glasses and fix them with self-tapping screws.
- We collect further sections. We fix all joints with self-tapping screws directly through the fittings.
Connecting pipes using fittings and screws
Tee connections look like this.

- The greenhouse is gradually gaining constructive completion.
An example of a greenhouse that is close to completion
- Suspended under the central upper longitudinal pipe wooden plank for mounting lamps.
The lamp strip is suspended from the central upper longitudinal pipe
- We cover the greenhouse with pre-cut reinforced film and fix it.
Covering with film goes something like this:
- We cut through the door and windows, strengthen the edges with tape. Here there is complete scope for creativity: you can cut out the door and windows from additional pieces of film, you can cut them directly onto the structure, sew or glue zippers or buttons for fastening.
