Today, Dutch greenhouse technology is one of the best in the world. In such buildings, you can grow quite large volumes of vegetables, berries, fruits and flowers, and the design features allow you to get the maximum yield from one plant. In our country, this technology is just beginning to gain momentum, but most farmers speak quite flatteringly about greenhouses made according to Dutch standards. You can find more information about this in our article.

What is a Dutch greenhouse?

Growing vegetables and fruits in greenhouse conditions has long been commonplace, but it was the Dutch designs that served as the starting point for business development in many countries of our world. Such structures, without exaggeration, can be called the best, but their use will be justified only in largescales. That is why the construction of a Dutch greenhouse, a photo of which can be found in the next section, is best done on large plots, and not on a private courtyard.

The advantages of greenhouses from Holland lie in their durability, since the highest quality materials are used in the construction process. For example, a metal frame ensures structural reliability even in the harshest conditions with strong winds. Durable coating allows you not to be afraid of large hail. And reliable insulating qualities give the farmer confidence that the crop is safe.

Design features

As mentioned earlier, the frame of Dutch industrial greenhouses is made exclusively from metal parts, since this material is highly reliable and durable. As a rule, a rectangular metal pipe with a cross section of 60 by 40 millimeters is used in the construction process. The upper trusses are made of thinner iron, since their main task is to fix the structure in one place, and the main load falls on the beams.

As for the coating, everything is extremely simple - cellular polycarbonate is the only right solution for the construction of the roof and walls of the greenhouse. Depending on the type of roof (curved, gable, and so on), there may be problems with the removal of precipitation. To do this, it is customary to equip greenhouses with a special metal drain, through which liquiddrains to the designated place.

Inside the structure is insulated with glass wool, especially at the joints of polycarbonate sheets and the contact of the walls with the ground. Particularly enterprising farmers create condensate drains inside, which originate at the ceiling of the greenhouse, and then move towards the water tank for irrigation. Well, or as an alternative, you can use a special gun that drains the room. Although such equipment is quite expensive.

Advantages of Dutch designs

Decided to grow roses in a Dutch greenhouse? To get started, we recommend that you familiarize yourself with the main list of advantages of this design, so that you don’t have to worry that your expensive flowers are in some kind of danger. It looks something like this:

• light penetrates polycarbonate in sufficient quantity;
• design dimensions allow growing any crops inside;
• greenhouses are equipped with protection against strong winds.

In addition, on an industrial scale, you can equip your greenhouse with almost any automatic system: drip irrigation, additional lighting, water heating, warm beds, and so on.

Disadvantages of Dutch greenhouses

No obvious shortcomings of the Dutch designs were identified. However, do not forget that such greenhouses are most suitable for industrial production, since the costs of theirconstruction will be quite serious. If you decide to put a greenhouse in your garden, then it is best to give preference to the classic version of boards and film. In many regions, the construction of such facilities is financed by the state, so you can return most of the funds for construction (300 rubles per square meter). Well, as a greenhouse for large scales, the Dutch version is best.

Ventilation

In the summer, any greenhouse should be well ventilated, especially when it comes to building in warm regions of the country. To do this, you will have to make special ventilation frames at a sufficiently high height (about 6 meters). This is one of the main features of Dutch greenhouses. Even if you make twice as many windows in a conventional design, but at a low height, ventilation will still not be as effective as in Dutch greenhouses, since the air speed is reduced due to plants that interfere with the normal course of the air flow inside. In addition, hot air is known to rise all the time.

Irrigation system

The irrigation system in Dutch greenhouses is fully automated and is based on special tapes that lie on the beds. Water supply is carried out using a water tower located in the center of the building or using a special pump that is connected to a computer. Also in containerwith water, there is usually a special department for fertilizing. Water is mixed with useful elements in the right amount, after which it is sent through the main pipes to drip tapes. By the way, holes in such tapes are located every 30 centimeters, so plants will have to be planted every 30, 60 or 90 centimeters so that water gets under the root, and unnecessary holes are simply sealed with adhesive tape for a while.

Shading

Did you decide to start growing strawberries in a greenhouse using Dutch technology? Then you will have to take care of additional shading in the hot season, since excess sunlight can adversely affect this crop (the berries will simply be baked in the sun without having time to grow to the desired size. Therefore, for the summer it is recommended to shade the greenhouse from the inside with a special shading net). To do this, it is necessary to put several lines of wire under polycarbonate at the construction stage, in order to then hang shading material on it. Well, by autumn, you can simply remove it so that the plants again enjoy more light.

Lighting

As for additional lighting, it is most necessary for young plants and seedlings. If your greenhouse has a special section for growing seedlings, then most of the fluorescent lamps should be placed there. However, several light sources should also be hung over adult crops (at least every 5-6 meters). Such actions will allow growing berries and vegetables.even in the winter season, without fear that there will not be enough light for fruit set.

As you can see, the Dutch greenhouses are high-tech facilities in which almost all the main systems are automated, and harvesting can be done throughout the year. However, the construction of such a structure can cost quite a large amount, so the technology is most suitable for professional farmers.
