A greenhouse or greenhouse makes it possible to get good yields, regardless of climatic changes. Vegetables and greens from your garden are really useful, because you know exactly what the plants were treated with, and therefore you do not have to risk your health.
Advantages and disadvantages
Greenhouses provide many benefits:
- The main advantage of growing plants indoors is the extension of the growing season. In a greenhouse made of cellular polycarbonate, you can plant seedlings 1-2 weeks earlier than the usual planting dates for a particular region.
- Plants are kept in an airtight, isolated space. It is more convenient to carry out preventive and curative measures in greenhouses. It is possible to fully implement the methods of Organic Living Farming without the use of chemicals.
- Modern greenhouses are successfully equipped with technical innovations. For example, automatic irrigation systems, the operation of which is carried out in accordance with the specified parameters. The system creates optimal conditions, in connection with which the yield increases by an average of 15-30 percent.
With all the positive qualities, greenhouses also have negative properties
- The constructions cannot be assembled without the appropriate skills, and the study takes time.
- Most greenhouses are covered with polycarbonate and are not scratch resistant.
- The strength of the material deteriorates over time due to exposure to UV rays.
- In an open space, plants are pollinated by insects, without this there is no harvest. In isolated conditions, the gardener must take care of the pollination himself, or he will have to buy self-pollinated plants. In addition, you will have to monitor the state of humidity, temperature, because without appropriate conditions, the pollen of plants falls off, you can also not wait for the fruits.
- Professionals do not recommend growing identical plants in the same place in a greenhouse. Crops must be swapped to do less damage to the plants. The harvest from year to year will deteriorate if the same crops are left in one place.
- If the greenhouse is not properly assembled, condensation will form inside.
- Polycarbonate tends to shrink and expand due to temperature changes. In winter, polycarbonate greenhouses often crack at folds and fixings.
- Over time, the aesthetics of the building are reduced due to the fact that transparent polycarbonate becomes cloudy, and color fades.
The main advantages of greenhouses are:
- convenience and ease of movement;
- insignificant weight;
- ease of installation;
- inexpensive price;
- no need to install a foundation;
- in high rates of moisture conductivity - plants do not require frequent watering;
- no need for special tools and equipment;
- in the optional possibility of adjusting the width and height of the greenhouse being equipped;
- excellent thermal conductivity, so that plants can be protected from frost and freezing.
Among the main disadvantages of greenhouses are the following:
- little resistance to winds;
- insufficient height of the structure, due to which the choice of plants possible for growing is limited;
- due to the peculiarities of fastening the covering material to the frame, it becomes difficult to replace it in case of damage.
Working with a greenhouse or greenhouse requires knowledge of certain nuances.To get rid of possible problems that may arise during operation, we will clarify the main differences, which will allow the use of structures with maximum productivity.
The greenhouse and the greenhouse are characterized by their own application features. A greenhouse is a structure, usually small in size, designed to protect the plant from poor climatic conditions, in particular, from periodic freezing temperatures in spring. As the plants grow, gardeners move them into the open ground. The greenhouse cover is usually light, intended for use in one season.
The greenhouse is characterized by a sturdier and more complex structure. The difference lies in the installation methods.
For a greenhouse, for example, you need a base, roof and walls, which are made from a variety of materials in artisanal conditions. Carbonate, film cover, glass are used. Profile of a classic greenhouse made of aluminum or galvanized. Greenhouses with a wooden profile require periodic touch-up and antiseptic treatment. If the greenhouse is covered with plastic wrap, it will last for 2-3 seasons. In addition, this material will provide poor-quality thermal insulation. Usually, it is customary to remove film shelters with the arrival of bad weather. Let's consider the constructive varieties of greenhouses and greenhouses in more detail.
The design of the greenhouse is more voluminous, more massive, often provides for the installation of a foundation. The varieties of greenhouses and greenhouses are similar, for example, they are gable. This design is easier to implement yourself. This species can be considered year-round, since in winter it will not break under the weight. A gable roof offers a wide range of coating materials.
The disadvantages of gable structures are not very high-quality tightness. The massive gable roof requires a reinforced base.
The positive characteristics of the arched structure are that it lets in more light. Cultures in such structures grow to a greater height than in gable structures. Of the negative aspects, the complicated care of tall plants is noted.
Another unpleasant moment is possible deflections and breakdowns of the arched structure in winter. If strong winds are observed in the region, arched structures are often demolished due to poor fastening of the frame to the foundation.
An unusual and rarely used design of greenhouses and greenhouses is a teardrop shape. The advantages of structures are many. Firstly, the snow on such a roof will definitely not linger. Secondly, warming up the soil in spring is noted as more efficient. The only negative quality of the design is the complexity of installation.
Polygonal options for greenhouses and greenhouses can be found even less often than the previous option. Polygons are more suitable for use as greenhouses. They are often made from different types of matching materials.
Plants receive more heat and light thanks to the external features of the Dutch greenhouse. The design helps to remove excess moisture, and also eliminates the effect of drops due to the accumulation of condensate. In addition, the Dutch greenhouse is resistant to strong winds.
It is easy to equip the greenhouse with an additional system for adjusting the level of sunlight penetration. The greenhouse itself can be equipped with stationary heaters or an entire boiler room. Inside, you can equip an automated irrigation system.
If greenhouses and greenhouses are structurally similar, then outwardly the structures are still different due to their size. Greenhouses are not equipped with doors and vents, since it is enough to remove the side of the structure to care for the plants. The height of the greenhouse is usually from 2 meters. The structure includes both doors and vents.
In terms of mobility, greenhouses can be considered a better option, since it is easier to move a small structure from place to place. Moving the greenhouse will be more difficult.
By deepening into the ground
Inside the greenhouse, tall beds are usually arranged, sometimes the plants are located on special shelves.
Greenhouses are set up with a deepening into the ground, plants are located directly on the surface. The soil in the greenhouse requires mandatory mulching.
By type of operation
The operation of the greenhouse is not year-round. It is designed for early growing plants or for growing short crops. The greenhouse can be operated all year round.
In winter constructions, you can grow not only the usual vegetables and flowers, but also exotic fruits. For a major winter building, a foundation is definitely needed. Summer greenhouses are operated from spring to autumn. In case of cold snaps, structures can be additionally heated by artificial means. In summer greenhouses, as well as in greenhouses, bioheating with compost, manure or humus is often used.
The greenhouse does not include any additional equipment. The greenhouse can be supplied with water, a convenient heating system.
Based on materials
According to the materials of manufacture, both structures can be identical. For example, both structures have a frame. A film cover or carbonate often acts as a protective material for both the greenhouse and the greenhouse.
Both the greenhouse and the greenhouse have an arched view of the roof. This is a kind of protection against water ingress. The liquid flows down without problems.
When choosing a design, you need to evaluate:
- the period that the plant should be in protected ground;
- the growth of cultivated plants;
- financial opportunities.
If you have a limited budget and want to grow early vegetables, it's best to choose a greenhouse. It can be installed somewhere in the middle of spring, and dismantled immediately after harvest. In the vacant space, you can plant other types of plants. The most inexpensive option for a seedling shelter is from a film.
If you plan to grow early crops such as cucumbers, tomatoes, it is better to take care of a stationary greenhouse installation. The cheapest construction is made of a metal frame, covered with plastic wrap. Polycarbonate sheets are the more expensive option. However, such structures are considered durable, since they do not deform from bad weather conditions. Combined structures look interesting options.
In recent years, the market has been replete with greenhouses covered with polycarbonate sheets. Greenhouses are equipped with side vents, with which it is convenient to ventilate.
The frame of such greenhouses is reliable, metal. Often, such structures are mounted on a stationary foundation. Wooden or brick bases are used. Modern manufacturers offer functional equipment for greenhouses, due to which the difference between the two options for structures practically disappears.
Modern buildings are distinguished by a variety of forms and functional content. However, prices and installation costs often force summer residents to look for ways to independently execute certain options. Before choosing, it is worth calculating the economic benefits of the planned project.
For example, a greenhouse that will meet the needs of a family - of one type, it will be of a completely different type if it is chosen to generate additional income. Investments in the second project will be much more significant.
Stationary models of arched or gable type greenhouses are more often suitable for those who live on the site all year round. Since there are frequent cases of thefts at dachas, it is better to choose a collapsible greenhouse that can be easily removed at the end of the season.
Interesting options for growing and irrigation systems, equipped in greenhouses or greenhouses.
There are ways:
- on the ground;
- on a variety of mixtures: peat, coconut, expanded clay, perlite, and mineral wool are used.
Watering methods are:
- simple, with a watering can;
- fully automated.
The above parameters can be easily changed after the greenhouse has been installed. Therefore, it is possible to minimize the costs of these systems, and take into account only the strength and durability of the selected frame and coating materials.
