How to choose the right greenhouse

How to choose the right greenhouse

If you want to solve the greenhouse issue once and for all, buy a greenhouse with a polycarbonate cover. After all, this honeycomb plastic perfectly transmits light, and the longitudinal stiffeners give the panels (2.1 m wide and 6 m long) the necessary strength.

The frost resistance of the material is also unique, because the panels are designed for use at temperatures up to minus 50 ° C (no load) and up to minus 40 ° C (with load). If you want a polycarbonate greenhouse to last for more than one decade, choose a material with a protective layer against UV rays.

Polycarbonate transmits soft ultraviolet light that is beneficial to plants and protects against the harmful effects of hard radiation; has low fragility; does not require a strong foundation for the greenhouse; does not collapse in case of accidental skewing of the frame.

When choosing a polycarbonate greenhouse, it is imperative to pay attention to the following frame characteristics:

  • the thickness of the metal profile is at least 1.5 mm;
  • the distance between the ties should be no more than 1 m;
  • the absence of drilled holes in the frame - this increases the strength of the greenhouse.
  • availability of reliable anti-corrosion protection of the entire structure;
  • snow load of at least 50 kg / m2 (for climatic conditions of the middle lane).

When developing models of polycarbonate greenhouses, the specialists of our company "Life in the Country" took into account all these features (see the table of the company's assortment). Let's take a closer look at the model “Life at the Dacha - PVC 3”, which is popular among gardeners. The frame is made of a round PVC profile - it is lightweight, durable, does not rot, does not corrode and does not require painting. The structure can withstand a snow load of up to 85 kg / m2. And also PVC frame and polycarbonate have the same coefficient of expansion when heated, and the coating does not "slide" along it, as it happens on metal structures.

Since polycarbonate and PVC frame materials are quite lightweight, there is no need to build a strong foundation and do concrete work. The greenhouse is installed on "piles": under each arc of the frame, a 1 m long stake with a special plastic nozzle is driven into the ground. An arc is put on the stake and fixed with self-tapping screws. This allows you to quickly assemble the frame and easily align its elements, as well as move the structure to a new place at any time. In order for the roof to withstand a force of up to 85 kg / m2, the greenhouse uses a supporting frame ridge in the form of a truss, which provides special strength.

New models of greenhouses - "Life at the Dacha - M" are made of a steel square shaped pipe 20x20x1.5 mm, clad in a PVC sheath, which protects the frame from corrosion. This technology allows you to extend the life of the frame and gives the greenhouse on the site a more aesthetic appearance. A PVC-sheathed steel frame is more practical to use than a galvanized or painted metal frame.

In new designs, the number of longitudinal ties has been increased to 7 pieces, which allows avoiding the pushing of polycarbonate under the weight of snow. Another important advantage of our greenhouse frames: there is not a single hole in the arches. By the way, to simplify transportation, each arc consists of two parts. Greenhouses of the "M" series are of 4 types in width, the length can be any, with a step of 2 meters.

Greenhouse cover

Let me remind you: I considered only greenhouses with a honeycomb polycarbonate cover. Since, before my shopping trip, I had already read the article Nuances of choosing and installing cellular polycarbonate for greenhouses and greenhouses, I knew that this material can be different in both its characteristics and quality. Therefore, I also considered the proposed options from this point of view. What turned out:

  • In the vast majority of cases, the manufacturer offers two configuration options products: only frame and frame with polycarbonate.
  • The offered polycarbonate can be as own productionand third party manufacturers... In the second case, options are also possible: a greenhouse manufacturer can cooperate directly with a specific manufacturer (as a dealer) or purchase polycarbonate from wholesalers or different manufacturers. The last option, in my opinion, is the worst, since it does not guarantee quality in principle. Occurs among small producers - serious firms still choose a different path.
  • A rare manufacturer offers the consumer a choice of equipment up to polycarbonate thickness inclusively more often (we are talking exclusively about the products that I have seen - I do not pretend to have a complete overview of the market) a variant with 4 mm thick polycarbonate is offered.
  • It is worth paying attention to the proposed fastening methods cover sheets to the frame: most manufacturers limit themselves to self-tapping screws, and only a few provide for fixing polycarbonate with galvanized tape (which is stronger and reduces the likelihood of damage at the attachment points).
  • Finally, many claim that their coating is of high quality and has protective properties against UV rays... I would not take their word for it and have read all the same with the relevant certificates.


How to do it right: Make a decorative garden

A couple of decades ago, the vegetable garden was a great help for the family budget. But now gardening is more of a hobby. Growing your own vegetables is unprofitable, labor intensive, hectic and responsible. However, it is very interesting! I'll tell you what is important to know about creating a decorative garden.

About the author: Oksana Razumovskaya, the chief landscape architect of our studio, has been professionally caring for gardens for over 27 years.

How does an ordinary vegetable garden differ from a decorative one?
A vegetable garden is a relatively small piece of land primarily dedicated to growing vegetables. It may also contain berry bushes and fruit trees. In the village and gardening associations, the vegetable garden is usually located in the immediate vicinity of the residential building.

The vegetable garden can be utilitarian: rows of beds, above them arcs with a film (greenhouse). And there is a decorative garden. For example, container, when vegetables are planted in beautiful containers and decorate them with terraces, patios in the manner of flower pots. Or in the form of rockery, using stones and gravel from the dump - this is usually used to grow herbs.


How to put a greenhouse correctly: requirements for choosing a place

Before proceeding with the construction of a greenhouse structure (or the installation of a purchased finished structure), the following list of factors must be taken into account, namely, such as:

  • - the degree of illumination of the place where it is planned to put the greenhouse
  • - wind conditions and the ability to protect the object from blowing and drafts
  • - relief of the selected area (lowland, hillock, etc.)
  • - remoteness of the selected area from the country house, power and water supply sources (keep in mind that, ideally, it is better to place the greenhouse not far from the indicated objects)
  • - drainage of the soil in this part of the backyard territory (is there a threat of waterlogging and stagnation of water in the selected area, or, on the contrary, does the water quickly go into the soil after a heavy downpour?).

Do not forget that when building wall greenhouses, you need to take into account much more nuances than when building a single structure. For example, wall objects can be either an independent construction or a full-fledged part of a country house (of course, with their appropriate arrangement and thoughtful organization of the internal space).

The degree of illumination of the area for the greenhouse is one of the key criteria that should be guided by when choosing a suitable place. Try to carefully study how well the area you like is illuminated, and how well the light falls on it in the cold season. By setting your greenhouse so that it faces south instead of north, you can avoid unnecessary costs for setting up and running a heating system during the winter months.

However, if the building is planned to be operated only in the summer, then you can completely put up with the long shadows formed in the low winter sun. For the same summer residents who plan to install a winter greenhouse on their site (the one that is operated throughout the year), our country site moja-dacha.com recommends turning the building to the south side - so that the sun's rays are not met on the way to no obstacles to him. The ideal option here is the complete absence of shade on the greenhouse building and its direct heating by the sun's rays.

If it is not possible to find places evenly illuminated by the sun on the backyard territory, then it is allowed to locate the greenhouse in such an area where it will be illuminated at least in the first half of the day (it is in the morning hours that the greenhouse buildings are coldest).

Wind regime is another important factor that needs to be taken into account when deciding whether to how to properly set up a greenhouse... By placing this object on a hillock or a wind-blown hill, you will get the exact opposite effect in the form of a constantly cold and, as a result, absolutely ineffective structure. If it is generally impossible to find windproof places on the garden plot, then it is better to install the greenhouse in the country so that one of its walls (the one that will be attacked by the wind) is reliably protected.

A good "shield" covering the building from the wind, in this case, can be made of protective strips of trees and evergreen shrubs (for example, from thuja), which can reliably protect the building at any time of the year. If the layout of the personal plot does not allow resorting to this option, then the greenhouse wall, which takes on the main wind load, will have to be insulated.

Consider also the fact that if the cultivation structure is protected from the wind by shrubs and trees, then it will be necessary to install the greenhouse with a reserve of "reserve" distance (at least 3-5 meters). Remember that over time, the roots and crowns of trees will grow, and shrubs will begin to stretch towards the greenhouse building, which can lead to a decrease in illumination inside the structure.

The threat of blackout should also be taken into account when installing a cultivation facility near other outbuildings. In this case, it may turn out that in the summer, when the sun is high in the sky, the greenhouse will be well lit, but in winter, with a low position of the heavenly body, the structure will be completely in the shadow of the neighboring building.

When considering how and where it is better to put a greenhouse on the site, pay attention to the direction of the prevailing winds, which in winter bring snow to the base of residential and non-residential buildings. If the cultivation facility is to be operated during the cold season, the snow accumulating on the outside can prevent optimal penetration of sunlight into the building. (And what owner of the dacha would be satisfied with the prospect of clearing the way to the door of the building every time after a blizzard, raking it out of snow drifts?)

However, for winter greenhouses, snow can also do a good job: reflecting the sun's rays from itself, the snow cover contributes to better illumination of the inner space of the cultivation structure. Here it is only important to make sure that the snow accumulating on the covering material does not interfere with the full penetration of sunlight into the building.

If your plans include the operation of the greenhouse building throughout the year, then it will have to be located in the place where there is a possibility of removing the upper part of the soil. By deepening the cultivation structure into the ground, you can protect it from the attack of the winter wind and drafts. But, resorting to this method, be sure to take into account the level of occurrence of groundwater, since otherwise there will be a threat of flooding of the cultivation building. By the way, in suburban areas where underground waters are located at an unsafely high level, it is allowed to install only ground greenhouses with a reliable, indelible foundation.

Thus, when deciding how to properly set up a greenhouse, preference should be given to extremely dry, as even and well-lit places located on a small hill.

It is highly undesirable to install cultivation facilities in lowlands and damp wetlands, since high humidity will inevitably lead to a decrease in the outside air temperature and a deterioration of the microclimate inside the building.

What if the greenhouse has to be placed in a damp place?

If it was not possible to find a dry and flat hill on the site, you should not despair. Previously, a damp place for a greenhouse structure will need to be thoroughly dried (usually this is done in the middle of the summer season, on a dry and hot day). Drainage works in the presented situation will provide for the removal of the fertile soil layer and the arrangement of a drainage system, which includes three elements:

  • - a water intake (it can be played by anyone, even an independently created canal or ravine),
  • - a set of open and closed drainage channels,
  • - drainage (crushed stone, broken brick, etc.)

When the work on the arrangement of the drainage system is completed, the dried-out fertile layer of the earth is returned back, distributing it over the drainage, and proceeding to the construction or installation of a greenhouse.

What are greenhouses and how to choose them correctly?

First of all, you should decide for what purposes this design is required. Many summer residents, in addition to the functionality of this design, pay close attention to its appearance so that it fits well into the interior of the site. There are also people who are going to do business on plants grown in a greenhouse - they, as a rule, care little about how it will look.

The type of greenhouse is also important: will it be located in one place, or is it still worth giving preference to a collapsible design. If there is no likelihood that someone will damage it or even steal it, then it is best to put a stationary greenhouse - such a structure still does not need maintenance, in addition, you will not have to spend time annually on assembly and disassembly.

The shape and functionality of the greenhouse will largely depend on what crops are grown in it, since each plant has its own property preferences regarding temperature, light levels and humidity, in addition, they come in different heights and so on.

The material from which the greenhouse is made is also different in its qualities. Cellular polycarbonate has recently gained the greatest popularity - it is able to withstand significant loads, not to lose its properties throughout its entire service life. The classic material is polyethylene film and its type is reinforced film. They are perfect for installation in a greenhouse of any design, the sun's rays pass well through it, ensuring the normal development of plants and reliably protecting them from frost.

When compiling this review, we took into account not only these points, but also relied on user reviews, took into account the value for money and many other parameters that one way or another should pay attention to the choice of model. We hope that our rating will be as useful as possible for you and will facilitate the task of choosing a greenhouse for your personal plot.


Greenhouse selection

Hello dear readers!

Let's talk about choosing a greenhouse for your site. I advise you to buy a greenhouse in the autumn, because having bought and installed a "house for plants" in the fall, in the spring you will no longer waste time, but will immediately start planting plants.

With the end of the gardening season, greenhouse prices tend to fall by 10-15 percent.

Before buying, decide what exactly you need a greenhouse for. For example, you can set up a small greenhouse for growing radishes, early greens and seedlings. Decide what types of vegetables you are going to grow - this will help you choose the greenhouse of the required height.

First, think about how much area you will allocate for the greenhouse, because its other parameters depend on this. If there is a lot of space, then it is better to put a couple of greenhouses: one for watermelons, cucumbers and melons, and the other for peppers, tomatoes and eggplants. Plants of these groups require different air humidity, temperature and watering. Thus, it is easier to provide the necessary conditions in different greenhouses.

At the same time, think over what shape your future building will be. If you plant tomatoes in it, then take a greenhouse in the form of a "house". These plants do not tolerate watering over the leaves, therefore, its roof must be covered with a reinforced strong film, and the side slopes - with any of the available non-woven covering materials.

Determine the model you need - collapsible or stationary. With the last greenhouse, there is much less fuss: I installed it once - and that's it. A collapsible greenhouse should be chosen if there have been cases of thefts in neighboring areas.

If by exercising greenhouse selection, You settled on a stationary structure, you need to choose the right dimensions. So the height in the cornice should be at least 1.65 m, and the height under the ridge - 2.4 m.The size of the door to the greenhouse should be 1.8 meters by 0.6 meters (if you need to transport cars to the greenhouse, choose the width of the door under its dimensions). When calculating the usable area of ​​the greenhouse, consider the space for the water barrel and paths. Consider how best to arrange the beds in the greenhouse: a path in the middle and two on the sides, or three beds with two paths.

The covering material that you plan to use requires no less attention.

The efficiency of the greenhouse, that is, the quality and quantity of the future crop, also depends on how to install it on your site.

If the greenhouse is directed by the facades (greenhouse doors) to the south and north, and the translucent slopes to the west and east, then this orientation is considered "meridian". If the slopes are directed to the south and north, then such an orientation is called "latitudinal".

According to gardeners, in areas located south of 60 degrees north latitude, the best efficiency is achieved with a meridian orientation, north - latitudinal.

In addition, it is necessary to take into account the wind rose, especially if there are frequent strong winds in your area. In this case, the greenhouse is installed so that the wind blows more on the facades, which have a much smaller surface area than the slopes. This will help keep the greenhouse warm more efficiently.

The distance between the nearest buildings or trees and the greenhouse is also taken into account so that the shadow from them does not fall on the greenhouse.


Position the structure so that it is well lit by the sun throughout the day. To do this, it is advisable to install it in length from north to south. Please note that the place must be protected from the wind: due to drafts, the air in the greenhouse can cool sharply, and this will not please the plants at all.

The optimal sizes of any summer cottage greenhouse are:

  • 2.5 meters to the ridge,
  • 1.5 meters - the height of the low wall,
  • 3 meters wide.

Plants are easiest to care for in a greenhouse in size, but you can change them at your discretion.

Ideally, the doors should be about 1 meter wide so that a garden cart or wheelbarrow can pass through them without problems.
