Do you want to open your own small business of growing vegetables? Or do you just need greenhouseto provide them with your family?
Please - offers on the market a huge amount. As a budget option, you can consider and do it yourself HDPE greenhouse.
Greenhouse do it yourself from polypropylene pipes
The choice of pipes for the greenhouse due to their strength. We will not be interested in such parameters as working pressure and other characteristics for water pipes. Pipe should be plastic and solid, withstand aggressive environment and heavy weight.
TO merits polypropylene can be attributed to it environmental friendliness - pipes from it are used to supply drinking water, which means the absence of harmful impurities in the material and fumes. The flexibility of the material allows the installation of arched structures. Such pipes are resistant to high temperatures. Another advantage of them is weight - They are the lightest of all plastic pipes. Greenhouse design can be easily transferred to another place, it does not require much physical effort to create it.
disadvantages few but rather serious. With -15 ° C polypropylene pipes become brittle and can collapse under the weight of snow. The frame of them must be disassembled and removed for the winter. Such pipes ultraviolet sensitive, which reduces performance properties - they can be deformed.
HDPE pipes of polyvinyl chloride have the same virtues as polypropylenebut more resistant to UV light.
The service life of pipes - from 10 to 12 years.
To make a greenhouse with your own hands polypropylene pipes, the pipe diameter (external) can be from 13 to 25 mm, depending on the weight of the covering material. For a film, a tube of 13 mm is enough, for polycarbonate - 20-25 mm. Wall thickness must be at least 3 mm. Such parameters will provide structural strength.

Film mounts
How to fix on plastic frame film without damaging it? Together with arcs for the greenhouse of polypropylene pipes usually go special clipsjust pinching the film in the right places. They are plastic, so safe for its integrity. They are sold separately packs of 10 pieces. When purchasing ready-made clips, pay attention to the diameter of the pipe for which they are intended.
Can do clamps with their own hands from the scraps of the same pipes. To do this, small pieces with a length of about 7-10 cm. They are cut along the wall and moved apart. Sharp edges can be processed sandpaper or to melt.
Is it possible to mount polycarbonate on the frame?
Can. Pipes are enough durableto withstand the weight of polycarbonate sheets. But here you need to focus on expediency. Greenhouses are built from polycarbonate and polypropylene pipes with their own hands, as a rule, taking into account wintering, they are not intended for permanent assembly disassembly.
BUT polypropylene badly withstands winter temperatures. In warm regions where winter temperatures do not fall below - 5 ° СThis option is fully justified. Where frosts crack in winter, it is better to make a collapsible film-coated greenhouse.
Preparation for construction
This, of course, is not a house, but preliminary preparation for the construction polypropylene greenhouses do it yourself is necessary.
The choice of location, design, foundation
It begins with a choice places, especially for stationary greenhouses. The construction site must be level so as not to have to complicate the construction.
It should be sunnyotherwise the meaning of its construction is lost.
Usually, a summer or stationary greenhouse is oriented with ends from south to north. So the sunlight will fill it all day.
Place must be protected from strong winds, from which steel structure may collapse.
If there is no such possibility, it is necessary to build a greenhouse so that it is protected at least from the northern wind carrying cold.
Greenhouse should be located at a distance 5 meters from other buildings on the site. Of polypropylene pipes You can build a greenhouse of any design - a house, arched, wall. The choice depends on the seasonality of use, financial opportunities and the area of the beds that are planned to be broken in it.
It also depends on what crops will be grown in it and how tall the plants will be. The most common summer design is arched greenhouse. It is aesthetic and functional.
Material for foundation and its type depends on the design. For light film greenhouses it will be enough to have a wooden base in the form of a timber or base from boards. For a permanent greenhouse with polycarbonate coating will need a more solid support.
It may be strip foundation. It is durable and suitable for removable design, if it is not intended to move around the dacha. Besides, wooden foundation will begin to rot, even if it is well treated with an antiseptic. It will have to be changed about once every 3-4 years.

Calculation of materials
amount pipes depends on the height and length of the structure, on the coating material - it will be a film or polycarbonate. For the film greenhouse, you can use pipes of smaller diameter, for polycarbonate, you need thicker, stronger pipes. In addition, to fasten the structural stiffeners, you must purchase couplings.
The calculation also includes the material from which the foundation will be made. The pipes are attached to it with metal fittings. Internal supports should also be provided. In addition, a fastener is calculated that will be used during construction.
Important! Before calculating materials, make drawing greenhouses.

Do it yourself: assembly instructions
How to make frame greenhouses from polypropylene pipes do it yourself? Greenhouse frame from HDPE pipes are perhaps the easiest to manufacture. For greenhouse size 10x4 you will need:
- baseboard 2x20 cm - 28 p / m;
- polypropylene pipes or HDPE diameter 13 mm - 17 pcs. 6 m each;
- fittings 10-12 mm, bars 3 m long - 10 pcs .;
- strips for lathing butts 2x4 cm in accordance with the drawing;
- plastic connecting clamps;
- fasteners (nuts, bolts, screws, brackets);
- aluminum fasteners for connecting arches with a wooden frame;
- film for coating;
- clips for fixing the film;
- locks and hinges for air vents (if provided).
Arched greenhouse with a frame made of HDPE pipes - step by step instruction:
- Shallow (10-15 cm) is dug out at the chosen place. trench around the perimeter of the greenhouse. The wooden frame is installed in it. The bottom is covered with sand or lined with roofing felt. Bar or board for the foundation must necessarily pass antiseptic treatment for longer life. Measure both diagonals of the frame, if they are equal, it means that it is set correctly and has right angles.
- In the corners of the frame, short pieces of reinforcement no more than the sides of the frame are hammered into the ground. They will keep the design from deformations.
- The rest of the cut pieces of reinforcement are driven in half the length along the walls on the outer side of the frame in increments of 60-62 cm.
- Six meter tubes worn on pins on both sides, first with one, then with a neat bend, with the other. Attached to the base board with a metal bracket.
- From the ends is done wooden crate. 4 racks are installed. The distance between them depends on the width of the doorway. Vertical slats are necessarily cross-linked to impart rigidity.
- Under the top of the structure is pulled stiffener. To do this, using plastic clamps, two polypropylene pipes are joined and attached to the arches.
- Last step - fixing the film with the help of clips - purchased or homemade. The bottom of the cover needs to be weighed down so that the film does not rise by the wind. You can press it with stones or a long bar.
Build from pipes polypropylene greenhouse even a novice in construction can do it. It will serve more than one year, if it is properly operated and, if necessary, replace the wooden frame at the base. Good luck to everyone and good harvests!
