Own greenhouse on the site is a good opportunity to provide yourself with early vegetables and high-quality seedlings of various cultures. It is possible to make such a construction in a matter of hours., thanks to the simplicity of design and compact size.
Using greenhouses
There are greenhouses in most household farms, many install them at summer cottages. Practically for every gardener, such a construction is one of the most important attributes of the site.
If the area is small, greenhouse can be arranged right at the wall of the house from the sunny side. When choosing a place you need to consider not only his illumination, but also wind protectionrisks flooding and rain erosion, soil quality.
The list of main crops that can be grown in greenhouses:
- radish;
- spinach;
- onions on greens;
- salad turnip;
- early cabbage;
- parsley and dill;
- salad;
- zucchini;
- early tomatoes;
- cucumbers;
- Strawberry;
- various ornamental plants.
Cold-resistant crops can be sown directly in the prepared greenhouse soil., but tomatoes, eggplants, peppers, cucumbers and others heat-loving species must be planted seedlings. To do this, their seeds are first germinated indoors using special cassettes or boxes.
When transplanting plants in a greenhouse is very important prevent thickened landingsAfter all, in close quarters, the stems are drawn out, lose their strength, and are more often subject to illnesses. Should be considered and open-air landing dates: overgrown seedlings obscure other cultures, complicates the care of plants, worse survives.
For the same reason greenhouse is not recommended to choose curly and tall species. For example, to get an early crop of cucumbers, give preference to better bush and low-grade self-pollinating varieties that do not need large space and do not require a garter.
Advantages and disadvantages
Film-coated greenhouses possess nearby advantages:
- the construction of such a construction requires minimum costbecause the film is one of the cheapest materials, and the frame can be assembled from wooden bars, fittings, metal pipes unnecessary in the household;
- to stretch and secure the film, do not necessarily have special skills;
- this coating is absolutely safely in operation, does not need special care;
- film greenhouse low weighttherefore it can be installed anywhere and does not require a solid foundation;
- film is great lets in sunlight.
It is possible to assemble and install a greenhouse alone. in a few hours. If necessary, the design is easily moved to another place at the end of the season, and as easily dismantled. To care for the plants and airing, the coating is simply rolled up on one side or tilted upwards on the frame.
There are film greenhouses and separate limitations:
- film ineffective with severe frosts and prolonged cold snaps, therefore the greenhouse is used only in a warm season;
- this coating must be removed from the frame for the winter and completely change in 2-3 seasons;
- on bright sunny days in tightly closed greenhouses occurs overheating of plantsfrom which they can die. To avoid this, you should open the greenhouse for ventilation in a timely manner or shade the film from above;
- weakly fixed to the frame will be blown away.
The device greenhouse film type
Despite the simplicity of the design, a greenhouse with a film coating has its secrets. Very important right pick up the material for the frame and properly fix the filmto avoid its damage. The simplest option is polypropylene pipeswhich easily bend into arcs, keep their shape well and do not rub the coating. The ends of the pipes can be stuck in the ground, but more securely fasten them to the frame of the boards.
Important! So that the greenhouse of the tunnel type does not move under wind loads, vertical supports of the bars are installed under the extreme arcs. The lower part of the bars driven into the ground, and at the top, for ease of mounting, cut out the recess of the tube diameter.
Wooden frames are more durable and resistant, but without special treatment, they do not last very long. If the choice fell on wood, you should take care of the purchase in advance. protective impregnation or paint.
In addition, all elements of the frame must be carefully sandedto avoid rubbing the film at the attachment points.
In the presence of fittings, steel angles or pipes You can make a frame of them, but such a greenhouse should immediately be installed on a permanent place or make collapsible. It should be noted that metal, unlike wood and plastic, heats up strongly under the sun and heats the film, which leads to premature deterioration of the coating.
In addition, the rough surface contributes to rubbing of a film in places of prileganiye. Both problems are solved very simply: rubber is put on over the metal (hose pieces, plastic tubes) and painted white. Rubber and plastic do not tear polyethylene, and the white color reduces the heating of elements by almost two times.
To make the greenhouse stronger, you must install additional spacers in the corners of the structure and stiffening rib from each side. If the structure is tall and long, you can put several vertical props out of the timber inside. Some gardeners prefer to strengthen greenhouses with the help of stretch marks from wire, stretching it between the frame and the pegs hammered into the ground.
How is the film fixed on greenhouses and greenhouses? Having dealt with the frame, you should take care of film fixing methods. On small greenhouses, she just pounce on top. and is fixed around the perimeter with something heavy, for example, pressed down with stones, planks, bricks. For larger structures This method does not fit. There are several options for mounting the cover:
- beadings or wooden slats and nails;
- furniture stapler;
- special mounting profiles;
- plastic clips of various diameters.
Fixing film with the help of beadings and nails does not require much effort, but the quality of such attachment is noticeably reduced by the end of the season. The tree cracks in the sun, gaps appear between the frame and the film, the coating is kept only on the nails. Two or three windy days are enough for the polyethylene to break off. Similar problems arise and when fixed with staples: over time, gaps appear in the attachment points and the film has to be changed.
Factory mounting profiles allow you to quickly and accurately fix the coating on the frame. They are suitable for both straight and curved sections, so they are often used in the manufacture of arch type greenhouses.
Working with them is quite easy, and the only drawback is the high cost of fasteners.
The most convenient and practical option of mounting the film when mounting it yourself is plastic clips for the greenhouse.
They differ in diameter and length, are highly resistant to temperature effects, serve at least 5 years. If necessary, the clips can be cut into pieces 2 cm wide.
Important! Since the clips have a round section, the frame must be made of reinforcement or pipes, for structures made of wooden bars and metal corners, they are not suitable.
The mounting process is very simple.: Put the clips in hot water for 1-2 minutes, then apply the film to the pipe and put on the fasteners, gently pressing them all over the surface. 4-6 clips from 8 to 15 cm long and at least 20 pieces with a length of 4 cm are required for 1 linear meter.
DIY assembly
How to make greenhouses and greenhouses under the film with your own hands: consider the photo and step by step instructions? First you need to decide on the size of the greenhouse and find the optimal place for it. In the absence of experience, you should not immediately occupy a large area, it is better to add later. By the size of the future greenhouse prepare the site: it should be located from east to west, be illuminated by the sun most of the day, have protection from the wind. The selected area is cleaned and leveled, the fertile soil layer is removed and set aside.
Now it is necessary pick up material, prepare tools for work. The easiest way to do it yourself PVC arched greenhouse type of pipe, film and strengthen it with a wooden frame. During the construction process will require:
- 4 boards with a section of 40x200 mm;
- rebars 70 cm long;
- PVC pipes;
- metal fasteners for pipes;
- thick plastic film;
- nails, screws and screwdriver.
Step 1. Boards soaked with antiseptic and dried in air. Further knock out a rectangular box the size of the future greenhouse and set it on the prepared site.
Step 2. From the inside at the corners of the box drive metal rods into the groundwhich will provide additional strength to the base.
Step 3. The length of the box from the outside drive in reinforcement every half meter. The rods must be buried not less than 30 cm. On the opposite side, they do the same, placing the rods parallel to each other.
Step 4. The pipes are cut so as to form pieces of the same length, after which they are put on the ends of the reinforcement protruding from the ground. Should turn out parallel parallel arc above the box.
Step 5. Take metal fasteners and fix the pipes to the boards with screws and a screwdriver.
Step 6. Fill the inside of the box with a layer of organic matter, then spread a layer of dry leaves or rotted straw, and on top of it pour a fertile soil with a layer of about 10-12 cm. Now you can cover the greenhouse.
Step 7. Unwind the film and stretch it on top of the arc. On both sides the film should hang down to the ground. With clips the cover is fixed on each arcwhile trying to maintain the same material tension. The bottom edge of the film around the perimeter powdered with earth or pressed down with boards.
At this construction is completed. It will be possible to start sowing after the soil inside has warmed up sufficiently..
So, with minimal cost, you can make a convenient greenhouse on the plot. Depending on the type of material (you can make a greenhouse with your own hands from a covering material), the assembly methods are slightly different, but the basic steps remain the same. If technology is observed, the greenhouse will last more than one year., providing its owners with environmentally friendly products.
