Who wants a house with a large greenhouse. Unique hydroponic greenhouse "Aleynu"

We are so accustomed to straight lines and angles that it is difficult to imagine something else in our summer cottage. We have square or rectangular houses and the same greenhouses. In the meantime, there are more advantageous forms of buildings, for example, one of the oldest forms used by nomadic peoples is domed buildings. Such buildings have excellent aerodynamic qualities, they retain heat better, and it is quite easy to build such greenhouses and even houses.

Tents can be called one of the first makeshift dwellings built by man. Teepees and yurts were light, simple and mobile shelters for nomadic peoples. But this design is not outdated - modern architects and designers use such structures to build huge stadiums and observatories. It turns out cool and at a minimum cost.

Frame and cladding materials

Dome structures assembled from straight parts are called geodesic. They are assembled into triangles, and the more triangles you make, the smoother the shape of the building will be. The material for the frame can be wooden slats, D20 metal pipes or PVC pipes.

There are several sites and forums dedicated to domed buildings. For example, rather old, but functional site desertdomes.com

There is a special calculator here that calculates the length of the parts for tents with different frequencies.

For example, you choose a dome with a radius of 10 feet (about three meters) and a triangle frequency of 2. The calculator calculates the length and number of parts and fittings for you.

Using metal pipes as material, you can easily compress their ends and drill holes in them for fastening with hand tools. Of course, with a vice and a drilling machine, everything will go easier and faster, but, in principle, you can do this with a hammer and a drill.

The more accurate the holes in the parts of the frame, the easier it will be to connect them later with bolts.

If you use wood for the frame, you can connect the parts with metal fasteners and screws.

Top Coat

When the frame is ready, it's time to cover the greenhouse. You can use plastic wrap, it is the cheapest, but will last no more than a season. You can also use a more durable reinforced film or PVC film, which can last up to three years.

Another option is to cover the greenhouse with sheets of cellular polycarbonate from 4 to 10 mm. Sheets can be simply cut with a knife and mounted on the frame.

Shape provides strength

The aerodynamic shape of the dome ensures the strength of the building even in strong winds. In addition, this shape allows you to maintain the temperature inside and evenly distribute heat.

For example, on a sunny day at -15 °C outside, the air in the greenhouse can heat up to +26 °C. And for a particularly cold winter, you can make an additional greenhouse inside the tent from wire and plastic wrap.

Dome house in two months

So, with minimal cost, you can make a solid geodesic greenhouse on your site. But that's not all the dome shape can be used for. For example, you can even build a country house, and, moreover, manage it in just a couple of months.

Of course, a house needs a foundation. For example, some builders in the Tyumen region used a pile-screw, which can be easily installed without the help of specialists. Of course, for heavier structures, a solid foundation is needed.

The frame of the house is built of wood with metal fasteners and sheathed with sheets of moisture-resistant plywood on top. Various heaters and materials are used for exterior decoration of the house.

Even kits for self-assembly of a domed house are sold.

As a result, beautiful round houses are obtained, which, despite their cheapness and speed of construction, are durable and retain the temperature well, which means they save on heating.

The high-tech "miracle" of the Israeli agro-industrial sector - the Aleynu greenhouse - presents a revolutionary concept to the human judgment, which, according to the creators of the project, is able to turn the mind of a person in his attitude to consumption. Greenhouse with an area of ​​4.500 sq. m. is located on a picturesque section of the road from Jerusalem towards the Dead Sea. The main activity of the greenhouse is the creation of an environmentally friendly bioproduct, specifically, the cultivation of various greenery.

Photo 2. In the short period of its existence, Aleynu's products managed to attract the attention of almost all major supermarket chains in the country. In addition to being a supplier of fresh lettuce, the greenhouse grows fragrant herbs that are used in the preparation of all kinds of seasonings. However, what really distinguishes "Aleina" from other farms of this kind is the educational moment. The revolutionary concept of rooftop greenhouses contains the idea of ​​farming in a post-industrial society. According to the creators of Aleynu, the greenhouse is a clear example of how traditional conventional agriculture is obsolete and unsuitable for providing the population with ecologically clean and fresh green products of the highest quality all year round in a modern city. In the photo you see the creator of the greenhouse - Ben-Zion Kabakov

In order to really understand the full benefits of urban greengrowing, it is worth considering in detail one factor first - the volume of greenery. The product grown on the roof of our greenhouse fits into a twelve-ton truck, while its weight is not even 300 kg. These 300 kg. it is quite possible to transport in a small car, however, due to the impressive volume, companies are forced to resort to the help of huge trucks that burn a lot of gasoline along the way and pollute the environment. In the case of vegetables and fruits, the situation is not so acute, since their weight is ten times greater. As a result, we get an absurd situation where thousands of trucks plow the continents, delivering greenery from the south of Spain to France and from California to Alaska and from Krasnodar to Irkutsk. Oil is burned, exhaust gases are emitted. Price? The consumer pays the price. And all this instead of growing greens directly in the places where buyers live - in the city. When the journey from the garden to the plate is calculated in hours, vitamins and minerals remain in the most intact form, and their health value is much higher. At the same time, irreparable damage to the environment is not caused when transporting products over long distances.

The whole logic of the development of society indicates to us that in the coming decades a new sphere of human activity will develop, and a new labor market will appear - urban agro-industrial production.

The new field of economy requires a deeper knowledge of plant morphology and an understanding of physical and chemical processes compared to conventional agriculture and, accordingly, more qualified specialists than today's farmers. It is among urban residents that it is easiest to find and educate suitable personnel, while simultaneously creating new jobs for citizens.

I see the future of urban farming in the unification of all forces and activists in the following areas:
- commercial, through:
— creation of a network of small microdistrict greenhouse farms with an area of ​​100 to 1,000 sq. m. each, united by a single harvest planning and cultivation protocol with a single system of cooperative marketing.
– creation of automated production agro-industrial greenhouses with an area of ​​over 2,000 sq. m. each, capable of providing tens of thousands of citizens with fresh products all year round at their place of residence.
- public, with an emphasis on the educational and educational nature of the activity, as an important part of the overall environmental protection program:
- equipping communal and private gardens, dachas and farms with agro-industrial hydroponic means of production to increase productivity and acquire the skills of modern urban agriculture by citizens.
- distribution of home hydroponic installations available to everyone, providing a successful harvest of greenery right on the windowsill, regardless of the weather, all year round. These plants are easy to use, do not require any prior cultivation experience, work without any control or additional equipment, decorate every home, become an integral part of the interior and represent the first experience of self-sustaining urban farming.

Photo 18. The company has developed and implemented a set of methods and technologies for the construction of automated industrial aeroponic greenhouses. Five years ago, in the suburbs of Jerusalem, Israel's first rooftop greenhouse with an area of ​​4,500 square meters was built and put into commercial operation. meters. This greenhouse produces over 3,000,000 of the highest quality plants per year. Cultivation is carried out in closed chutes filled with moist air and mounted on a conveyor. The chutes move along the conveyor from the planting point to the harvest point. Throughout the journey, the human hand does not touch the plants. Near planting, young seedlings grow densely, close to each other, since in the first couple of weeks the seedling develops mainly the root system and does not require much space under the sun. As the plants grow, the automated conveyor increases the distance between the plants. Thanks to this, a more efficient use of planting areas is achieved, and the technology allows you to collect 2.5-3 times more plants per unit area compared to conventional planting methods adopted in greenhouses. So, for example, the average planting density in our greenhouse is 60 plants per square meter.

Photo 19. The farming methods used in this greenhouse were adopted by the Israeli Ministry of Agriculture in the development of a new quality standard for agro-industrial products, IsraGAP, known for its strict attitude to the control of the use of pesticides. "IsraGAP" is an informal name similar to GlobalGAP.

Photo 20. Alas, today the phenomenon of "urban agro-industrial economy on the roof" has not yet received recognition. And since water tariffs and municipal taxes are calculated according to the legal status of the land, these tariffs are tens or even thousands of times higher than conventional agriculture, which kills the very idea of ​​​​urban agro-industrial economy in the bud. As always, Israeli bureaucracy stands in the way of Israeli high-tech in new areas

A blanket, warm socks, hot coffee - this is the first thing we resort to if the weather is bad outside and the house is not too warm. But the people of Stockholm Charles Sacilotto and Mary Granmare decided to approach this problem from a different angle.

The couple initially decided to build energy efficient house from scratch. But then they met the architect Bengt Varna. The man offered them his very interesting concept, which interested the spouses.

The couple purchased a small house around which a greenhouse was built from 4 mm protective glass.

Such a project has a huge number of advantages: the temperature inside stays around 20 degrees Celsius, even when it drops below zero outside. In addition, the family has covered terrace and your garden.

The couple grows very outlandish products for Scandinavia inside their home: figs, tomatoes, cucumbers.

But most of all they like to spend time under a glass roof. Here Charles and Mary sunbathe, play with a child or simply relax.

True, the spouses admit that from time to time they have to turn on the heating for a short time, because the system simply cannot work without failures all year round.

It is undeniably unique, though not the first of its kind. I am sure that the spouses do not regret that they once decided to build it!

If you like this idea, be sure to share it with your friends and acquaintances!

Even experienced summer residents in the middle of the first decade of the new century began to abandon the greenhouse, they say, there is a lot of trouble, but the result is not so impressive. Moreover, the younger generation is inciting: tomatoes are sold on every corner, and all summer you bend your back over one bush.

But the next crisis seems to put an end to these doubts and reasoning. A greenhouse is needed. It allows you to get a good harvest of fresh herbs and vegetables, and environmentally friendly products. And this is not only saving the family budget allocated for vegetable products, but also for medicines, because clean products allow you to maintain health, receive vitamins and microelements. The only question is how, with less money spent on the purchase and maintenance of a greenhouse, to grow a full-fledged crop without a headache either from the cold or from overheating ..

The best option for a high return on a greenhouse is if someone lives permanently in the country from spring to autumn. This is quite realistic for pensioners today, because modern technologies, at low cost, make it possible to insulate a country house and create comfortable living conditions in it. But permanent residence does not cancel some measures to facilitate physical labor in the country.

If the holiday village is protected, then, of course, the best option is a stationary greenhouse covered with polycarbonate. It will serve for many years, even without heating, it will allow you to grow greens and vegetables from the end of March to November. The arched structure on the foundation will save on covering material and will withstand wet snowfalls without problems.

The word "foundation" does not mean at all that a concrete base needs to be poured under the greenhouse. The best option is a base made of wooden beams, treated with anti-rotting agents. It will play an important role in the thermal insulation of the greenhouse, and will successfully serve at least 10 years. And this is an excellent time, because in a small garden it is extremely problematic to use the greenhouse in one place, it is easier to install a new foundation and move the frame with polycarbonate.

If cases of theft in your village are not uncommon, then it is better to make a good foundation on which you can quickly and easily install a collapsible greenhouse and cover it with a dense high-quality film. Such a greenhouse is also beneficial for the reason that in snowy winters it will not suffer from snow load.

I have already written about the choice. Perhaps, we can also mention the new generation of cellular polycarbonate labeled Bio, which guarantees an increase in yield and the amount of vitamins in vegetables. Actually, this, as in the case of the film, is the result of the action of light-transforming additives. I would prefer just such a polycarbonate, remembering that the effectiveness of light-transforming additives will fall after a certain number of years. As far as I know, manufacturers give a guarantee for 10 years.

I will add that it is very important to find a material whose price and quality are in harmony. In the comments to that article, we recalled how strong and durable the reinforced film produced in the 90s was, and how quickly it now crumbles. Same with polycarbonate. The first roof of my polycarbonate greenhouse has served faithfully and partially still serves for more than 20 years. But one day I decided to change the design of one slope and, foolishly, partially used a piece of newly purchased polycarbonate. So he served only 3 years, but I already notice signs of destruction along the edge of the roof overhang.

This I mean that you need to buy from a conscientious seller material produced by a company with a good reputation.

And further. In the case of polycarbonate, you should not save money and neglect special edging and connecting tapes - they significantly increase the life of the material and provide a high level of transparency.

Until recently, the glass greenhouse was considered the most perfect. In it, the earth freezes a little, thaws quickly, keeps heat well and has high light transmission. The main disadvantages of such a greenhouse are the need for a solid foundation, expensive materials and construction work. But if you position your suburban real estate as an estate, then it makes sense to incur the costs of a fundamental greenhouse. True, I would abandon traditional glass as a fragile and dangerous material, and replace it with a modern monolithic polycarbonate. It is light, flexible, with high light transmission and 4 times less cold than glass. The price is high, but...

Whatever excellent covering material we choose, the quality and durability of the greenhouse directly depend on the frame. This was experienced by many summer residents in the winter of 2013, when many vaunted structures collapsed from the snow load, at the same time destroying the coating. Now, blowing on the water, at the end of the season, summer residents install spacers and supports in their greenhouses. To be honest, I have not heard that someone was patient and sued the manufacturer. And as long as we support “reliable and durable structures” with sticks from the forest, low-quality goods will be sold on the market.

Alas, the most reliable design for a year-round sheltered greenhouse in the conditions of the Russian winter remains handmade. The best option is from a wooden block. Properly designed and made, it will serve for a long time and reliably, and the material will not let the cold into the greenhouse. Welded metal structures from the do-it-yourself series are also reliable, but the metal itself is a "cold bridge".

However, not everyone can afford a greenhouse to order, so we have to choose from what a huge army of manufacturers offers us, focusing on our wallet and the reviews of the owners of the “greenhouse from the store”.

Ecology of consumption. Manor: Scientists from the Netherlands who created an unusual house-greenhouse. The essence of the idea is to combine energy-efficient technologies and a garden complex in one dwelling.

Citizens are often deprived of the opportunity to purchase truly fresh, only vegetables and fruits plucked from the garden. And many suburban residents do not always have the opportunity to grow everything they want on their site. For example, heat-loving plant species. The limited area of ​​​​the site or unsuitable climatic conditions affect. The solution can be a greenhouse-thermos device.

Thus, the researchers want to test the idea of ​​building an autonomous house that can feed its residents.

For a bold experiment (its completion is scheduled for 2018), a house was built using frame technology, with a glass roof and transparent walls on the third floor.

The house is oriented to the cardinal points. The angle of slope of the transparent roof is designed in such a way that the plants receive the maximum degree of solar insolation. If necessary, the windows are covered with curtains. In addition to the greenhouse, the house was equipped with a rainwater collection system, which is used for irrigation and technical needs, a solar collector, and a ground heat exchanger.

Tests have shown that the idea works, and a variety of vegetables and fruits can be grown in the greenhouse all year round. For example, watermelons, tomatoes, peppers, beets, zucchini and cauliflower.

In order to bring the experimental conditions as close as possible to the natural environment, a family of four settled in the house (according to the results of the competitive selection). Under the terms of the experiment, people should live in their usual rhythm. Despite the theoretical training and detailed briefing, the townspeople had a hard time. The lack of practical experience of life "on earth" affected.

So, people had to adjust their work schedule to the garden. Getting up early in the morning, assigning responsibilities, weeding, fertilizing, deciding who and on what day waters, cares for plants, controls the operation of the ventilation system, etc.

According to Helly Scholten (the wife of the head of the family), they once left home for a few days in the summer, and when they returned, they found that the plants planted in the vertical garden had died due to heat and lack of moisture.

This served as a lesson to the family and made them treat the experiment not as a fun game, but as serious work that requires a lot of effort and knowledge. Things went well. Now the Dutch are fully self-sufficient in vegetables and fruits, and even have a surplus.

The developers of the project emphasize that although the house is experimental, the technology is being worked out on it, ways are being sought to improve the dwelling combined with the greenhouse. In the future, the researchers plan to put the production of house kits on stream so that everyone can get their own personal garden. published
