Greenhouse own hands

Many owners of private houses on their dream of having a greenhouse areas.This agronomic building owners will provide your family with fresh herbs and some types of vegetables in the late spring or early summer.Well, some of the design of greenhouses that involve heating and lighting used to grow crops all year round.

Greenhouse own hands

Greenhouse own hands may be built of wood and brick in combination with metallic elements, having a carcass structure, for example, made of a light metal pipes.

In implementing the ideas in the first place is determined by the place where it will be installed a greenhouse.From its area directly depends on the size of the future structure.

Next, you need to decide when to use this facility - in the spring or during the whole year.If you select the "winter" option, then you should know that the building will be much more expensive, as the materials for it will require more and will be necessary to carry out the lighting, heating, plumbing and ventilation.

Then, select the type of material of manufacture and construction of greenhouses.To dwell on one of them, some of the most frequently used options will be considered.

greenhouse design, in principle, is not very complicated, so it can build any site owner alone.To do this, you need only prepare the material and tools.Greenhouses can be divided by type, starting from a variety of criteria - is the manufacture of the material, the shape of the structure, permanent or temporary, it will be.

material for covering greenhouses

to cover greenhouses used several different types of materials.They should be transparent, may be favorable for the growth of plants shades.For example, polycarbonate, which has become particularly popular in recent years, sometimes chosen not only colorless, transparent, and yellowish or green.

Polycarbonate cover greenish

often to cover the walls and roof of the greenhouse glass is used.It is in its structural composition and the transparency is excellent for this room, but to set the glazing must create a highly reliable solid frame construction, as this material has a considerable weight.Capital winter greenhouses sometimes erecting of metal-plastic frames and double glazing, but such a structure will cost very expensive.

Traditionally, glass is widely used for creating transparent walls and roof

Traditionally Another option, which is used most often for covering greenhouses is a polyethylene film for creating transparent walls and roof glass is widely used

.It can be used for pulling on the frame, constructed of any material, since it has a very small mass.Recently there has appeared a special reinforced film that is more durable, and it is easier to fix on the sheathing frame.

To determine the choice of material, you need to carefully examine its performance, which are presented in the following table:

Fastening and weight has a low weight, and in certain constructions can be used without any additional elements of the frame, andalso without the base. Glass has the largest weight in comparison with other coating materials, and by selecting it, it will be necessary to consider reliable frame mounted on the foundation. polyethylene has a very small mass, but requires a special attachment.
If the material is not reinforced, it is fixed to the frame through a special rack and further fixed ropes stretched thin.
Durability Polycarbonate greenhouses as a coating can last 18 ÷ 25 years, depending on its quality.
This material is flexible and has sufficient rigidity to be self-supporting element of the design.
Fixed on the frame, it is not deformed and does not bias.
Glass can last for a long time, since it is not influenced by UV rays and moisture.
On the other hand, the glass is brittle and inflexible material, therefore does not tolerate mechanical impacts, loads and large deformation of the carcass structure.
Polyethylene has the lowest service life in comparison with other coating materials, as affected by UV light, which is gradually degraded.
In addition, you can not call it sustainable and to temperature.
Noise Polycarbonate well suppresses wind noise and rain, thanks to its structure. If the material is made of poor quality installation, during strong wind gusts air can penetrate inside, and glass to issue ringing. film does not protect the greenhouse from the noise, and if the wind is very strong, then the material will be greatly rustling in the wind.
Appearance Polycarbonate structure gives aesthetic look and can make a real gem of a conventional greenhouse area. Properly installed glass greenhouse will give a neat appearance. film looks neat and is transparent, only the first season of its use, and that - not always.
Then, under the influence of the sun, temperature extremes and wind, it becomes turbid and loses its aesthetic appearance and light transmitting capacity.
Security Polycarbonate has high strength, exceeding that of glass, about 200 times, and the easier it is about 15 times.
Falling material is not fragile and can not injure by fragments which are in or near the greenhouse of people.
Poorly installed glass - is extremely dangerous for people working inside.
In addition, if the pieces fall to the ground a greenhouse, you can seriously hurt in the subsequent conduct of cultivation.
Therefore, if it is planned to install the glass, it is recommended to entrust the installation of professional craftsmen.
perfectly safe for people and for the greenhouse soil.
Care For this material easy to maintain - it is enough to wash with water, setting a strong pressure in the hose.
However, it should be noted that the dust on the surface of the polycarbonate is almost invisible, so the greenhouse do not have to be washed frequently.
On the glass there are traces of the drops of rain, and well retained the dust.
To get rid of the dirt on the surface, you need to make a lot of physical effort.
particularly uncomfortable and dangerous to carry out harvesting activities in the greenhouse roof.
PE film does not wash, because after wet cleaning on it remain divorces, and it becomes cloudy, making it difficult to complete the penetration of light inside.
only solution when very dirty - complete replacement of the film.
Generated microclimate Polycarbonate can reliably be insulated greenhouse and protect plants from wind.
vapors deposited on the inner surfaces, drain them into the soil.
In addition, the material is not only perfectly passes light, but also makes it more soft and diffused.
heat generated by soil and plants, is securely stored inside the building, which creates the greenhouse effect.
Glass is not able to create a high thermal insulation, if it is not made of metal construction with double-glazed windows.
material perfectly passes light, but does not dissipate it, and sometimes even a bed focuses on specific, which is extremely harmful to the plant leaves.
Dense new plastic film is able to create a high insulation, but this season, under the influence of temperature, sun and wind, it becomes thinner and loses its original qualities.
therefore recommended coating films change every year.

weigh the "pros" and "cons" of materials, as well as taking into account the design of the planned structure, you can choose the type of coverage.

Construction of greenhouses

Greenhouses have different designs - this can be a large room, or just a big box, covered with glazed frame.Used as buildings, leaving half of its height in the ground.Opt for one of the species will be possible only after the owner will understand the features of each.

  • The simplest greenhouses design that can be built from scrap materials, consists of a conventional box, the size, for example, 2000 × 1500 mm, assembled from planks and installed in a favorable area of ​​territory.For such as greenhouses roofs often use old glazed frame.

These greenhouses are commonly used for the cultivation of sprouts or greens from early spring to late autumn.

  • Another option simple and accessible in the construction of the greenhouse is a simple frame structure made of reinforced plastic or polypropylene pipes, fittings, and sometimes even of thick steel wire, covered with plastic wrap.

If greenhouse plastic pipes are selected, the frame of which the strength to make even the female hands, as this material is easy enough to bend and keep their shape well.

greenhouse Such an option can be used during the spring-summer season, starting with spring and ending in late autumn.Ease of construction is that the seeds are planted under a film, for example, tomatoes, after emergence and consolidation, the seedlings can not be transplanted.It simply thinned, and in establishing a stable on the street and a comfortable temperature for the plants, with the construction of the film is removed, opening the free flow of air and sunlight.In very hot weather, to the newly created frame can be quickly thrown over a special mesh that creates a penumbra, but allows light to penetrate right to the plants.

  • more complex structure, which is collected from a wooden bar and they cover film can also be used throughout the spring-summer season.Dimensions such greenhouses may be different - they vary on how many seedlings planned to plant, and with a view to ensuring the convenience of working gardener.

In this design, be sure to provide a hinged lifting roof to access the plants to sunlight and air.It - also a seasonal version of the structure, and it is advisable to use it only for the cultivation of seedlings, as summer temperatures in stable vegetables and herbs recommended to grow still in the open field.

  • If you want to grow a small amount of greens or sprouts, it is possible to make a greenhouse out of metal barrels, in which the slits are made in the form of windows.As the roof in this design uses plastic transparencies - it at any time can be removed by opening access to the air, and close to the cool night off-season did not cause damage to plants if necessary.

  • more sophisticated greenhouse construction in which it is already possible to set a moderate heating and start using it has a very early spring.It consists of a wooden or metal-plastic frame.This is a full room, and it not only plants, but also the gardener will be protected from the wind and cold temperatures.This greenhouse can be covered by a very dense polyethylene film or cellular polycarbonate.When creating the design of the pipes, it must be remembered that it is easy enough to get, and a strong wind can move it, damaging the seedlings, so for her reference to the place you need to drive into the ground, metal corners or fittings.
An interesting solution - the greenhouse frame is welded from very expensive polypropylene pipes and accessories.

  • Capital structure greenhouses equipped with heating and irrigation, can be used throughout the year.To a greenhouse to work effectively, it is usually made of a plastic composite or aluminum construction and glass, which set the foundation.

For easier maintenance heating and water delivery to the premises greenhouses, quite often, these designs is attached to the south wall of the house.In this case, the structure will serve as a kind of a winter garden that will delight owners not only fresh vegetables and herbs, and ornamental plants color in every season.

  • Another version of the winter greenhouse, whose design helps save on heating - this room it takes to half their height in the ground.This structure, thanks to its high-quality energy-saving, often called the "greenhouse-thermos."To achieve the desired effect, for this greenhouse dug pit, leaving deep into the soil for 1600 ÷ 2000 mm.In addition, above-ground height of the wall being built 500 ÷ 700 mm, and then the entire structure is covered with a skeleton made of timber or metal bracket.

Work on the construction of the structure is quite laborious and long-lasting, but in the course of its operation will be enough to save his system of heating.One of the important moments in the construction of greenhouses, a thermos is not only the improvement of the heating system, and effective ventilation.

Form greenhouse roof

Another criterion by which the greenhouse is divided, is the shape of the roof.
