Any summer resident or the owner of a small country house, at least a little keen on farming, must have at his disposal a mini polycarbonate greenhouse. A standard plot of 4-6 acres does not allow for a more solid construction, and if you do not consider gardening as a small business, then a “mobile” greenhouse frame is enough to grow seedlings and get quite a decent crop of early vegetables or flowers by a certain date. A "miniaturization" of greenhouses and the use of modern plant cultivation technologies have led to the fact that some models can be installed directly in the house.
Polycarbonate mini-greenhouse in the area
If we consider only the structure, and not technical equipment, the greenhouse from the greenhouse differs in size and method of arrangement.
An ordinary greenhouse literally "creeps" above the ground, has a temporary frame of separate sections without a base, which is placed directly on the ground. His task is to ensure the growth of greens, vegetables and root crops in the spring, when the probability of night frosts is high. More often the framework is covered with a film, less often with sheet transparent materials. Maintenance of the greenhouse and the care of seedlings occurs "from above" with a partially removed cover. When steady heat comes in, the greenhouse is dismantled until the next season, and the plants remain in the open ground.
A conventional greenhouse has a more solid construction. It may have a small foundation and a stationary place assigned to it. The size of the greenhouse in length and width can be any, the shape and type of the roof of different models are also different, but at the highest point of its height should provide free movement of the person. The most "advanced" samples can have their own heating, lighting, ventilation and irrigation systems, with automatic control and temperature control, timer for switching on the fan, lamps and auto-irrigation.
The difference between the greenhouse (left) and the greenhouse (right)
The mini greenhouse takes an "intermediate spot". It is also low and compact, like a greenhouse, and served "from the top" or "side". As a translucent material may have a film, polycarbonate film or glass. Its construction is more rigid, although even assembled, it is “mobile” and can be easily moved.
Differences from the greenhouse in the simplest models for the dacha and the site are so insignificant that many manufacturers and sellers call this category a “mini-greenhouse greenhouse”.
A technically equipped mini greenhouse can have its own "life support" systems, up to and including the cultivation of plants using hydroponics and aeroponics technology.
Country models of mini greenhouses of factory production are made of aluminum or steel profiles. The covered area usually does not exceed 3 m 2 , and the height of the “one-story” structure is within 1 m. The aluminum profile does not require coating, the steel profile is zinc coated and a layer of powder paint is applied. For ventilation and air access, part of the translucent cover can be removed, and the method of ventilation depends on the materials of the fence.
Still mini-greenhouses are used as a greenhouse.

The most inexpensive mini greenhouses for giving use a plastic film with a thickness of 200 microns. The disadvantage of such covering material is low strength and wear resistance. Plastic film is not more than two seasons, and sometimes it changes every year. Another disadvantage is that it is inconvenient to air such mini greenhouses - every time you need to fold or fold a part of the film on one side of the frame
Unlike polyethylene, transparent PVC film is more durable and last several seasons. From it make a cover in the form of a cover, in which provide air vents for ventilation. The cost of PVC film is more than polyethylene, but not by much. And since the cost of the frame makes up most of the price, this covering material dominates the mini greenhouse market.
For reference! Many manufacturers for their models sell PVC film covers separately. This is attractive for two reasons - you can replace the old coating with a new one or “copy” the framework construction from other materials and get another mini greenhouse.
Mini-greenhouse with polyethylene coating
Another popular soft material is spunbond. This is a type of non-woven textile that has a very wide specialization.For greenhouses and mini-greenhouses use white translucent material, which consists of special stabilizers absorbing ultraviolet light (marking SUF). Advantage of a spanbond - porous structure. This ensures the breathing properties of the shelter, capillary penetration of sediments and the natural maintenance of an optimal microclimate.
Analogues of spunbond - lutrasil, agril, agrin, agrospan. They also belong to non-woven synthetic agrotextile, have similar properties and are used in crop production as a seedling shelter and in the manufacture of mini-greenhouses.

Of all possible sheet translucent materials, only honeycomb is used to make mini polycarbonate greenhouses. Its advantages:
Cheaper than a solid sheet of the same polymer.
Thanks to the air gap, it has good thermal insulation properties.
In cellular polycarbonate, the strength is slightly lower than that of a monolith, but internal stiffeners make it sufficient to withstand severe mechanical loads (for reference: monolithic polycarbonate is 200 times stronger than glass and 8 times stronger than acrylic glass).
With the same thickness, it weighs less than normal glass by 16 times, and acrylic glass - by 6 times.
The light transmission of a two-layer transparent honeycomb lies within 75-86%, and this is enough for normal plant growth.
Polycarbonate is a thermoplastic material. It is possible to make arched mini greenhouses from it, which have the following advantages:
higher structural strength;
less aerodynamic resistance to wind;
luminous flux is better dispersed.
In a polycarbonate mini greenhouse, it is easier to organize the ventilation - to make a window or a folding part of the section.
A light mini greenhouse that can be installed alone in a few minutes
It would seem , in order to grow seedlings of ordinary vegetable crops at home, apart from crates and pots, no additional shelters are needed. But this is the case if the house is maintained at the optimum level of humidity, and in the winter in a heated room in the living rooms the air is a bit "dry" for tender shoots. Two more mandatory conditions for normal growth - good light and no drafts. In winter and early spring, if you do not use phyto-illumination, a lot of natural light is only near the window (on the table, rack or window sill), but when airing the room drafts are inevitable. And in order to create normal conditions, it is better to use a home greenhouse, in which plants are grown not on the ground, but in boxes and pots.
Previously, home craftsmen themselves produced mini greenhouses for the home. Now this possibility is not excluded, but there are many ready-made models for every taste and budget.
If desired, such a greenhouse can be installed on the veranda or terrace
And for fertilizers you will not have to go far

The simplest mini greenhouse for a house is a small stack of painted profiles and welded mesh as shelves. It can be put on the window sill or stand next to the cabinet, and the same cover made of PVC with a window leaf or a lifting canopy will be protected from drafts.
A home greenhouse can be in an enlarged format and with a large number of shelves - in the form of a floor shelving. The height and distance between the shelves allow you to grow more "tall" plants.
The advantage of this kind of mini greenhouses is that they can be easily transferred from the house to the plot, when the temperature outside allows it. And if they were in a city apartment, they can be disassembled and transported to the cottage.
More serious and solid home greenhouses are made in the form of a cabinet with doors, side walls and a cover made of glass or transparent polycarbonate. Imported samples are not cheap, but they can be made to order in any company engaged in the manufacture of commercial equipment - the design is simple, and the profiles and other components are the same as those of glass slides and display cases.
Mini home greenhouse for growing seedlings
Mini greenhouse when The plant needs individual care.
All mini-greenhouse designs listed above require constant monitoring and maintenance. But there are models that minimize human involvement - the mainboxes and growouts.
If you approach strictly, then this is no longer a mini greenhouse - the walls at the cabinet (box) or cover (awning) are light-tight. Lighting and ventilation occur in automatic mode - this is the minimum set of functions of the simplest device. In more advanced versions, the system itself monitors the microclimate in a confined space - temperature, humidity level and irrigation.
For growing plants in growthboxes, completely different crop-growing skills are needed. Soil preparation, fertilizer, watering, regimes, seeds, and the plants themselves are all very different from ordinary, soil cultivation. It is rather a hobby, a hobby - the yield of soil crops is higher than that of those grown in growboxes, and the costs are lower.
In addition to ready-made structures, there is a whole industry for the production of components for the manufacture of grobitboxes of any size - from a drawer with a drawer size to the equipment of an entire room set aside for this purpose.
Obviously about growing boxes, see the video:

The mini greenhouse allows the city dweller to spend his free time in an interesting and useful way. In order to grow early vegetables, flowers or contain strange plants, a lot of space is not necessary - this can be done in the country or at home. It is enough to choose from ready-made models or to make to order a compact "desktop" or ground greenhouse.
