All the pros and cons of a buried greenhouse inside out
The golden hands of a real man make an invaluable contribution to the well-being of the family. Nevertheless, he should know all the pros and cons of a buried greenhouse before taking on such a grandiose project. The unique design functions as a thermos greenhouse. This type of structure allows you to maintain a proper microclimate inside the building. As a result, earthen structures allow farmers to significantly save energy and other resources of the farmer.
Showing the pros and cons of a buried greenhouse
As a result, an underground greenhouse for year-round gardening will be able to:
- serve for more than a dozen years;
- function in all weather conditions;
- become an ideal place for growing greens, vegetables, seedlings, as well as flowers;
- keep a rich harvest in a short summer;
- provide plants with heat without additional installation of heating equipment.
Professionals recommend covering the buried greenhouse with polycarbonate. The material is distinguished by its special strength, flexibility, durability and thermal insulation.
Ultraviolet rays penetrate into the earthen structure through the roof. Therefore, the farmer does not need to worry that the scorching sun will destroy his harvest. In addition, this system of growing crops allows you to save on irrigation. Due to the unique structure of the greenhouse, the earth warms up moderately, retaining a sufficient amount of moisture for plants. Yet the pros and cons of a buried greenhouse did not end there. The negative aspects of such a capital project include the significant costs associated with the construction of a thermos greenhouse.
Cons of an underground greenhouse or finance singing romances
Building a greenhouse structure is like building a small house. A very deep trench is being dug under its foundation. In the northern regions or Siberia, farmers have to submerge the building to the maximum depth, because the ground in those places freezes up to 1.5-2.5 meters. This, in turn, is associated with even greater costs. The main problem with greenhouse construction in the ground with their own hands, groundwater often becomes, which does not allow penetration into the ground so deeply.
In addition, additional funds will be needed if:
- strengthening walls with insufficient soil density;
- constructing a suitable drainage system;
- erection of a solid supporting frame;
- installation of a heating system, because the harsh winters of the northern latitudes are merciless.
According to all the rules of agricultural technology, in-depth greenhouses are equipped with a powerful ventilation system. This standard recommendation should not be ignored. Otherwise, mold and fungal infections will become true friends of the gardener and the crops grown.
Yet given the right capital, the farmer needs to invest in this worthwhile business. If he plans everything carefully, he can even launch a successful business and ultimately make a good profit.But how to build an underground greenhouse so as not to suffer damage. For this, it is important to know some of the intricacies of building a greenhouse.
Features of the construction of a deep greenhouse
The choice of a place for a greenhouse building is a determining factor in this matter. Agronomists suggest finding a suitable place on a hill or on a flat area to avoid flooding the structure. Gardeners note that the larger the greenhouse, the more stable the microclimate is maintained in it. For this reason, it is not worth saving on the construction of an overall greenhouse.
In addition, the gardener needs to consider:
- Direction of the wind. Air masses create a draft, which is why you have to spend a lot of money on heating an underground building.
- Relief. Many farmers build a buried greenhouse with their own hands on the slopes of the hills. Thus, they save on walls as well as heating.
- Lighting. Trees should not grow near the building, which, with their shadow, impede the penetration of sunlight.
Location of the buried greenhouse. The ideal place would be the latitudinal location of the structure - from the east to the west. Ultraviolet activity in this position occurs in the first half of the day, when the intensity of photosynthesis is at its maximum.
A universal type of earthen greenhouse is a gable greenhouse with brick walls. The depth of pouring the foundation is 80 cm when used strip base... The walls are erected in one brick, coating all joints with a waterproofing solution. In parallel with this, they are reinforced with vertical metal devices. The optimum roof pitch is 25 крыши. It is constructed from glass or polycarbonate. Even garden crops can be grown in such a thermos greenhouse.
Dimensions of a buried greenhouse. The height of the aboveground part is about 1 meter, and the underground part is up to 1.5-2 m, depending on the terrain. The optimum construction width should be no more than 5 meters.
Single slope recessed greenhouse project
Buildings of this type are constructed from a wooden frame, consisting of 3 rows of racks. The height of the greenhouse is determined by the base to which it will adjoin. The dimensions of the outer side of the structure vary from 160 to 180 cm.
The greenhouse frame is made of three types of material:
- wooden beams;
- profiled pipes;
- polyvinyl chloride profile.
For laying the foundation, one of the proposed options is also chosen: larch beams, concrete mortar or brick blocks. A harness is formed in the lower and upper parts of the supporting frame. Further, it is strengthened with struts and slopes, which are installed under the rafters and between the racks. Then they think over the holes for windows (on the roof), as well as doors. The cladding is made of polycarbonate (100 mm).
To avoid annoying mistakes, you need to correctly and accurately depict a drawing of a thermos greenhouse.
In such a complex process, diagrams and drawings of the building will become assistants to the gardener. The precise dimensions of a buried pitched or gable greenhouse will help the grower build a reliable and practical building that will last for decades.
