Home greenhouse for seedlings with hands. Greenhouse for growing seedlings at home. Greenhouses for seedlings from plastic bottles

Growing good quality seedlings is troublesome and labor intensive. To do this, she needs to create the right climatic conditions. Everyone dreams of a good harvest and fast plant growth. In the past few years, small mini-greenhouses have become the most popular. They create ideal conditions for the growth of cultivated plants, both in the personal plot and in the apartment.

Mini-greenhouses are used to grow cultivated plants not only in the summer cottage, but also within the walls of a city apartment. It is suitable for planting whimsical and thermophilic varieties.

Protects young plants from winds, drafts and precipitation.
Provides the necessary climatic conditions for plants.
Young seedlings do not get sick when transplanted into open ground, since addiction occurs slowly and gradually.
Plants are easy to care for.
They are not only easy to install, but also easy to store.

Most summer cottages are small in size. Full installation is impossible. Since such structures occupy most of the site.

Differences between greenhouses and greenhouses

All gardeners know that there are two irreplaceable structures on the backyard for growing not only seedlings, but also adult plants. But there are significant differences between them:

Height no more than 0.5 meters.
It lacks vents and doors.
The greenhouse is heated in a natural way. For this, sunlight and bio-fuel are used.
You can change their location.
These are temporary structures that are used mainly only for the summer cottage period.
Year-round use is possible indoors.

Views

There are many types of miniature greenhouses. They can vary in size, shape and cover material. We present to you several popular types that can often be found both in the apartment and on the site.

"Home"

The design is small in size. Fits on any windowsill. Used for growing. In design, they are similar to street greenhouses, but in miniature. Installation in several levels is possible. You can design it yourself or purchase it at a gardening store.

Portable plank construction

It is a box-like structure that does not have a bottom. Polyethylene film or glass is used as a covering material. Its convenience lies in the fact that, if necessary, it can be installed anywhere on the site. Its main application is to protect plants from frost.

"Belgian"

To build this model, you will need to dig a ditch. In it, equip ridges with fertile soil. Cover the top with polyethylene, glass in a frame or a sheet of polycarbonate.

It is best to build this type with a shed cover. You save space on your site.

Model "Butterfly"

Named after a small feature that opens the doors on both sides. They are visually similar to a butterfly. The main advantage is access to plants, which is possible from both sides. It can be any size, but in most cases they use small structures that do not take up much space on the personal plot.

Bread box model

It has one sash that rises completely to the top. The roof is semicircular. The sash is opened by sliding it over the main part of the roof. Plants are easily accessible. The place on the site does not take up much.

"Shelf"

An unnecessary rack or cabinet is suitable for the construction of this type of greenhouse. The cabinet is left without a back wall and is covered with polyethylene or covered with polycarbonate. Instead of doors, frames are used with the same covering material that covers the rear wall. Visually, this design resembles a shelf from a store. It is easily installed on any balcony or loggia of a city apartment and is used all year round.

Wall model

This miniature structure is installed against the walls of outbuildings or a house. Compact. Great design for small areas. The roof is mainly of a pitched type. There is a minus, but not significant. In winter, it is required to constantly clear of snow.

From scrap materials

Small greenhouses that do not require any financial investment will be a good solution in arranging a personal plot. And they will take very little space on the site.

Plastic bottles

For the construction of this mini-greenhouse, you need a simple bottle of 5 to 10 liters. Making a greenhouse out of it is simple:

Cut a rectangular hole. You do not need to cut one side. This will be the door of the future greenhouse.
Fill the bottle with nutrient soil.
Plant seeds are planted.
After the seeds have ripened and rooted, the greenhouse is opened.

Do not forget to make several holes in the side of the bottle, which is parallel to the door. This is a drainage system for removing excess moisture.

Old tin barrel

From an old barrel that has not been used for a long time, you can make a mini greenhouse. This process is simple and consists of several steps:

Cut several holes from the sides of the barrel.
A dense covering material, for example, double-folded plastic wrap, is attached to the upper edge of the barrel.
The holes should be at a level where you can comfortably follow the plants.
The barrel is filled with earth and the plants are planted in it.

Window frames

A mini-greenhouse made of this material is installed once and should not be moved any more. The old window frames are heavy and massive. To install them, you will need to build a foundation. Further, construction is carried out as follows:

Window frames are cleaned of old paint and covered with a wood decay and insect protection agent.
For the frame, you will need - a rack (1 piece) and a pair of straps.
The floor is being concreted.
The roof is made of a gable type.

Materials for making

The construction of a mini-greenhouse is a process that is based on the use of improvised means. It can be created from anything. Mainly used by:

plastic;
metal profiles;
wooden bases;
plastic wrap;
polycarbonate sheets;
glass.

If the design of your mini-greenhouse has an arched shape, then the installation of a flexible frame is required for its construction. Common materials for such bases are plastic and metal profiles. Wood can be used, but it is highly susceptible to decay. Polycarbonate is irreplaceable and modern. It is also possible to use plastic film and glass.

Glass makes the structure heavier and therefore, first of all, you will need to take care of strengthening the frame or installing the foundation.

Professional gardeners use a specific covering material for certain mini greenhouse models:

Polycarbonate sheets are suitable for the Butterfly and Breadbasket models.
Polyethylene - for those structures that will be located in the apartment, at home, on the balcony.
Glass - for stationary greenhouses on a personal plot.

Features and Benefits

The mini-greenhouse maintains a high temperature regime and can maintain constant air humidity for a long time. If you live in a city apartment. A small greenhouse is a great place to grow greenery.

It is also suitable for growing seedlings of whimsical plants. After all, many gardeners have met more than once with the fact that when planting seeds, their germination was zero. When grown in mini-greenhouses, optimal conditions for germination are created.

Main disadvantages

Like any design, a mini greenhouse has not only positive aspects, but also negative ones. These include:

do not tolerate strong winds;
the range of cultivated plant varieties is narrow, since the height of the greenhouse is small;
it is difficult to replace the covering material if it is damaged, since the attachment to the frame is difficult.

How to choose a design

Each garden, suburban or other piece of land is unique. It can differ in landscape features of the area, in its size and, of course, in the composition of the soil. In order to create ideal conditions for plant growth, you should carefully choose the design of a mini-greenhouse. To do this, you need to consider:

individual characteristics of the land plot;
what area will be allocated on the site for it;
what kind of lighting will be used;
what volumes of seedlings or plants will be grown.

Taking into account all of the above, you can choose the desired type of mini-greenhouse for your site and seedlings.

Installation of different types

Mini-greenhouses, depending on the type of supporting structures, can be built using several different methods. For greater clarity, let's start step-by-step recommendations for construction with a mini-greenhouse that does not have a frame.

Such a greenhouse is a bed covered with plastic wrap or other identical material. Seeds are sown and covered with a covering material on top, and they are pressed along the edges with bricks and wooden yards.

Arched mini-greenhouse, instruction

To build an arched greenhouse, you will need to adhere to the following instructions:

For construction, you need 5-6 arcs made of plastic or metal profiles, polyethylene film, a couple of meters of wire and about 20 clamps.
Arcs are made by hand or bought in a store.
They are installed at a distance of 35–45 centimeters from each other.
To strengthen the frame, a wire is pulled between the arcs.
Cover the resulting structure with a film. Then they attach it on one side with clamps.
On the other hand, the film is attached to a wooden strip. It is from this side that your greenhouse will open.
From the sides, the structure is also covered with pieces of polyethylene and pressed to the ground with a brick or wooden lath.

Portable polycarbonate, instruction

To build a portable greenhouse made of polycarbonate leaves is a more laborious, but no less interesting process. This will require:

wooden slats;
self-tapping screws;
awnings;
lever.

Instructions that must be followed when building this mini-greenhouse:

Make a base frame. It should resemble a box with a slanting top.
The frame is mounted from the rails. It is used to create a greenhouse roof.
A piece of polycarbonate sheet is inserted into the frame.
A support for the frame - the roof - is erected from a wooden block.
Attach a hook to the lid to fix the frame on the bar.

These construction methods are quite simple to install, but they provide seeds and seedlings with optimal climatic temperatures and humidity for germination and further growth.

Bio-fuel in greenhouse construction

There are situations in which additional heating of small greenhouses is needed. Biofuels can do this very well. Its installation is quite simple.

After the place for installing the mini-greenhouse is established, a small hole is dug.
Mix manure, straw and dry leaves with earth and place in a pit.
Watered thoroughly with water and place fertile soil on top.

The layer of fertile soil should be thick enough for the plants to grow well.

Now a greenhouse is being installed.

The heating process is based on the decomposition of biological additives. Due to the release of heat, additional heating of the soil under the plants occurs.

There are a huge number of mini-greenhouse designs and everyone will be able to choose for their site exactly the one that will provide the best growth of seedlings and other garden crops and at the same time will not take up a large amount of space on the site.

A mini greenhouse is a great way to grow healthy, high-quality seedlings, which gradually gets used to future growth conditions and, after planting in a permanent place, does not get sick and gets used almost instantly.

For a serious gardener, the presence of a greenhouse pavilion on the site is mandatory. But for the construction of a stationary structure, not everyone has a place or resources, so a mini-greenhouse is an ideal solution - a simple and effective shelter for plants that can be easily assembled from available materials.

For all their simplicity, these structures provide an optimal microclimate for the plants planted in them and allow not only growing seedlings, but also getting an early harvest.

If you ask a layman who is not privy to the secrets of the construction of greenhouse facilities, how greenhouse shelters differ from greenhouses, then, most likely, you will hear in response - a small size. But this is not entirely true. There are indeed mini greenhouses among them, suitable only for growing seedlings, but this is only one small group.

You can build a small shelter in the country yourself

The main difference between these two types is the way the microclimate is formed under the shelter.

If in a greenhouse the microclimate and biorhythms of plants approach natural, then a humid warm climate is formed in the greenhouse, saturated with oxygen during the day and carbon dioxide at night. The soil serves as the main source of nutrition, therefore it is quickly depleted and needs regular fertilization. Plants in greenhouse conditions grow intensively due to the rapid accumulation of plastic reserves.

A polycarbonate greenhouse can be compared to a small greenhouse.

for thawing and warming up the beds in early spring;
growing seedlings;
forcing early greens and radishes;
early planting of crops with a long vegetative period;
protecting plants in the garden from late frosts;
acceleration of fruiting;
obtaining several harvests per season;
creating an optimal microclimate for heat-loving crops.

Types of greenhouses for beds

Mini greenhouses for garden beds are very easy to build on your own. To do this, it is enough to choose a covering material - film, agrofibre, polycarbonate or glass, prepare supports and correctly orient the entire structure.

Ground shelters for insulation

Agrofibre beds warm up faster

One of the annoying problems of the gardener is the discrepancy between the timing of warming up the soil and the timing of sowing crops. This can be easily corrected with the help of earthen shelters. This is done this way: after the snow melts on the site, the beds are covered with a greenhouse film or agrofibre.

The soil under the shelter warms up 10-14 days earlier, and the temperature under the film is 10 ° C higher than the ambient temperature, which allows you to plant seedlings earlier, sow greens or vegetable seeds when the weather has not yet settled down.

Simplest tunnel shelter on arches

Tunnel shelter on arches

This small "Snowdrop" type greenhouse is easy to build from available tools - agrofibre, PVC film or polyisopropylene. Suitable for growing seedlings, forcing greenery and for early planting in the ground. Arches are used as supports, which can be made of thick steel wire, galvanized profiles, metal-plastic pipes or long rods.

How to make a home mini greenhouse with your own hands:

Prepare a site for the construction. If necessary, lay compost or manure under the garden bed, pour 30-40 cm of fertile soil on top. It is better to make the bed width 0.6-1 m, length 2.5-3 m, orientation from north to south. Along the perimeter, you can fence the garden bed with boards so that the earth does not creep.
Depending on the length of the ridge, prepare 6 or 7 pipe sections with a length of about 2 m and 12-14 pegs (50 cm) for driving into the ground and fixing arches. If there are no pegs, then it is better to take the pipes half a meter longer in order to securely fix them in the ground.
Bend pipes into arcs up to a meter high. You can make a special template on the board or use a large iron barrel of a suitable diameter.
Drive pegs on the long sides of the future blinking greenhouse every 50 cm. Fix arches on them (or stick arches into the ground 25-30 cm below the soil level).
Install a connecting strip on the arches or simply tie the arches together with a cord or wire.
Secure with foil or agrofibre. You can use clamps or just tie.
On the north side, collect the hanging end of the covering material, pull and secure, on the south side, you can leave it free.
Fix the film on the soil around the perimeter. It is better to take stones for this, and not sprinkle it with earth, since periodically you will need to lift the film to access the plants.

Box with transparent lid

The cassette mini greenhouse is ideal for growing seedlings and early radishes. A box with a height of 40-50 cm for it is made of boards, the width and height of the frame are chosen according to the size of the upper shelter. For early sowing of seeds into the soil, it is recommended to select the soil in the box to a depth of 40 cm and fill the hole with biofuel. Fertile layer - 20 cm of normal soil. For pallets with peat tablets, it is better to make the frame small - 0.5 m * 1 m.

Cassette greenhouse with peat tablets

For the cover, you can take old window frames or tighten the top with a film (or better with agrofibre). You can also use thick glass or triplex, but in this case, you need to make sure that the edge is glued or carefully sanded. After seedling under cover, you can grow young greens - onions on a feather, herbs, watercress.

It is better to orient such a structure from south to north.

Modification of a cassette greenhouse - a box with a transparent lid. Its difference is that the upper frame is installed at an angle in relation to the soil surface. In length, they are located from east to west, the south side of the frame is usually half the north. The dimensions of the box are arbitrary, and for better illumination of the plants, it can be made of a polycarbonate roof.

The butterfly house is a convenient portable shelter

A mini-greenhouse of the "house" or "butterfly" type is suitable not only for growing seedlings. Depending on the height, tomatoes, peppers, eggplants, cabbage, cucumbers and other vegetables can be planted in it for early harvests. Such shelters can be assembled from scrap materials - boards, slats, film, agrofibre, polycarbonate.

Greenhouse scheme "butterfly"

The easiest way to make such a structure is to mount the frame from slats and cover it with foil or sheathe it with polycarbonate. For polycarbonate, the frame can be assembled from a galvanized profile.

A distinctive feature of this type of greenhouse is that the gable "roof" is movable on both sides. This makes it easier to ventilate and care for the plants.

Cucumbers in a greenhouse "house" under a film

To grow cucumbers, you need a mini-greenhouse of a slightly different design:

At the chosen place, prepare a bed for two rows of plants and make a wooden strapping. Such a "house" can be arranged on the south side of the house, but the seeds must be sown in one row.
Fasten the uprights for the side walls to the harness. The height of the central post is 1.5 meters.
Connect the central posts with a longitudinal strip. A twine for garter cucumbers will be attached to it, so you need to make it strong.
Sew up the sides with foil, glass or polycarbonate.
The removable roof can be made in the form of a frame with cladding, or a film, which, if necessary, is simply rolled up and tied up.

Original solutions for country beds

Home greenhouses are not only a significant help for the gardener, but also a way to realize their creative ambitions. These designs prove once again that even a piece of straw or leftover foil will be used by the thrifty owner.

Straw-protected crops

Greenhouse made of straw and window frames

In horticulture, straw is often used for mulching beds and as a material for warming perennial plants in winter. In this design, straw bales act as a building material for the box. Due to the properties of straw, it is good to retain heat and moisture.

The air under the glass warms up quickly, and the plants get a head start in two to three weeks. Window frames or polycarbonate are used as the cover.

Straw bales and foil frame - efficient design

Protective foil umbrellas

Late frosts are a serious threat to the crop. Sometimes you have to literally save the beds from death - to huddle all the plants or urgently fill up especially valuable specimens with straw. But the problem can be solved in another way.

Individual "umbrellas" of two arcs and a piece of film or agrofibre are able to protect against frost. The arches are fastened with construction tape, the film is fastened with clips.

The same devices can be used for glasses with seedlings during the hardening period - during the day the plants are hardened, and at night they are reliably hidden from hypothermia.

Two arcs and agrofibre will save you from frost

An old plastic barrel - in business

If the farm has an old plastic barrel with a capacity of 200 liters, then in half an hour you can build a spacious greenhouse mini-greenhouse. You can grow seedlings, greens, even mushrooms in it. The design retains heat and moisture well. In addition to the barrel, you will need construction scissors, film and construction tape. For detailed instructions, see the video.

Lattices and pallets are an excellent frame

The framework for the simplest tunnel shelter can be assembled in an hour from waste materials. Useful gratings, pallets, regular slats or thin boards. Finished sections are fastened with tape and covered with agrofibre. The soil in the beds warms up quickly and seeds can be sown.

Sections are held together with tape

Under such a roof, the soil warms up quickly

The use of wood helps to avoid any negativity - it does not rust, does not release chemicals, does not react with fertilizers and herbicides.

The second life of old refrigerators

Good mini-greenhouses come from old refrigerators, which are easy to get from landfills or neighbors.

The engine, cooling system and door are removed from the body. The lid is made of glass or polycarbonate. Refrigerators keep temperature and humidity well, so an ideal microclimate is created inside. The only thing that you need to worry about additionally is the drainage holes under the ground, since without them, excess moisture will lead to rotting of the roots and the death of crops.

Greenhouses from old refrigerators in the country

Polycarbonate for mini constructions

Small polycarbonate greenhouses are lightweight, durable and comfortable. From this material, it is easy to build almost any model of a mini-shelter. The only drawback is that such construction can be expensive. But it is not necessary to buy whole sheets on purpose. You can use the pieces left after the large-scale construction of a gazebo or greenhouse.

In addition to polycarbonate, you will need material for the frame (slats or galvanized profile), screws and a suitable scheme.

Small greenhouses for an apartment

For the keen summer resident, the gardening season begins in February. And it doesn't matter that the entire site is covered with snow - seedlings can be grown on the windowsill. And small home greenhouses from scrap materials will help in this.

Peat pellet trays

Popular peat pill trays can be bought, but it's cheaper to make your own from an egg tray and plastic containers (bottles or cake boxes). Water the seedlings in tablets through a tray.

Operating procedure:

Drill a drainage hole in each recess in the tray.
Select a suitable plastic packaging (pallet and cap). If there is no large container, then the egg tray can be cut. Several holes must be drilled in the hood for air exchange.
Put a peat tablet in each cell and pour over.
After 10 minutes, the tablets will swell and you can sow seeds in them.
Place the seed trays in pallets and close.

Egg Tray Will Replace Peat Pill Tray

If there is no suitable container, then the cap for a mini-greenhouse can be made of plastic plastic bottles:

Cut the transparent bottles carefully.
Cut 5 rectangles from the panels for the box (do not forget the allowances for gluing). Select the size so that the tray with tablets fits freely inside.
Glue the box-cap with tape.
Use a tray as a pallet.

Plastic box

Cakes or biscuits can also be used to grow seedlings. Holes are drilled in the walls for drainage and ventilation, the soil is filled up - and the mini-greenhouse is ready for sowing work.

Mini greenhouse from plastic containers

Plastic bottles as greenhouses

Waste material - plastic bottles, in the skillful hands of a gardener often turn into useful devices. In addition to irrigation devices, mini-format greenhouses are often made from plastic containers.

Method 1. Greenhouse-glass for seedlings:

Cut two bottles in half
Place the upper part in the lower glass of the first bottle and fill with soil.
Sow the seeds and close the bottle with the other top.
Don't forget the drain holes.

Growing in a bottle

Method 2. Seedlings in bottles:

Cut a bottle with a volume of 6-10 liters lengthwise, leaving the threads intact.
Drill holes in both halves
Pour soil into the lower part and sow seeds.
Close and seal the cut with tape.

Greenhouse from a plastic bottle

Home mini greenhouses are a good alternative to industrial polycarbonate and tunnel structures. It is easy to build them, but you can use them both in the apartment and on the beds, so be creative and create, then your harvest will always be rich.

Growing seedlings is a complex of complex agrotechnical measures, each of which is of equal importance. In this article, we will consider only one factor - the creation of an optimal microclimate.

For growing seedlings outdoors, it is advisable to use mini greenhouses.

What are their advantages?

Versatility of use. In such structures, it is possible to maintain the parameters of humidity and temperature for all types of plants.
Mobility. Mini-greenhouses can be moved to other places annually, taking into account the peculiarities of seedlings and the availability of free space on the site.
Low cost. For construction, both purchased and any scrap materials are used, the remains of pipes and metal, the field of installation of complex engineering systems, used structures, etc.
Minimal loss of time. The simplest structure can be made in an hour; for more complex reusable use, it will take no more than one day.

In this article, we will consider several options for manufacturing greenhouses using various materials and technologies. This information will allow summer residents to choose the best option for themselves, to realistically assess their capabilities and harmonize them with their needs.

Mini greenhouses from sawn timber for seedlings

The most affordable option for manufacturing, several boards are always available at their summer cottage. How to do it?

Step 1. Think over the dimensions and specific location. For a mini-greenhouse, a length of 2 m and a width of 1 m is sufficient. The height is selected taking into account the width of the boards.

Practical advice. There are options for the manufacture of inclined mini-greenhouses, in this way a water stack is provided. We advise against doing this for several reasons. Firstly, rainwater will never harm the seedlings, let it fall into the greenhouse and natural watering is carried out. Secondly, one high side shades the plants, which does not benefit them. Plants in the shade grow weakened, the stems are too elongated and thin. Third, such a structure is more difficult to manufacture. Why do you need to worsen the conditions for growing seedlings with your own hands?

Step 2. Assembling the box. Cut two boards 2 m long and two 1 m long, trim the ends under a square. There are two ways to assemble the box: end-to-end or using bars. The second method is preferable, when assembled end-to-end, thin boards can crack. To avoid such consequences, we recommend pre-drilling the holes, the hole diameter is 0.5–1.0 mm less than the diameter of the hardware. True, in this case, it is desirable to use self-tapping screws, the pressing force with ordinary nails may be insufficient. If the greenhouse is stationary, there are no problems, and if it is planned to move it to a new place, then the structure may collapse.

Practical advice. We recommend to strengthen the box, this will significantly increase the time of using the mini-greenhouse. Reinforcement should be performed with isosceles right-angled triangles, the side length at the apex is about 10 cm. Prepare 4 such elements and fix them at all corners. It is better to install the squares from above, so they will not succumb to decay processes.

Step 3. Now you need to choose the option of covering the mini-greenhouse: using glazed window frames or ordinary plastic wrap. For long-term mini-greenhouses, we recommend making glazed frames, they are stronger and more reliable, and it is more convenient to use such devices.

How do you make them?

For a length of 2 meters, three frames with perimeter dimensions of 100 × 66 cm are sufficient. Frames can be made from a bar of approximately 50 × 50 mm.
Cut the bars to size, you will need 6 pieces for three frames. length 1 m and 6 pcs. 66 cm long. Make a glass chamfer on one side. Chamfer dimensions up to 5 mm in depth and width.
It is better to assemble the frame using metal furniture corners, it is simple, easy and fast. The corners are fixed with self-tapping screws or studs 20–25 mm long.
Take measurements under the glass, cut and install it in place. To increase the reliability of the fastening, glazing beads can be used.
On the inside, along the perimeter of the box, nail small slats, the frames will lie on them. There is also a second option - to increase the size by several centimeters more than the width of the box, then the window frames will rest against the sides.

At this point, you can finish the production of a mini-greenhouse, install it in place, prepare the soil and plant seeds for seedlings. But we will consider a few more options for lumber greenhouses.

First option. Hang the window frames on the hinges. This will make opening / closing them somewhat easier. In the open position, the structures rest on special stops. The disadvantage is that some of the seedlings will not receive enough full spectrum sunlight. Glass does not transmit ultraviolet rays, and it is they that have a negative effect on pathogens.

Practical advice. Do not use cheap furniture piano hinges, they are non-separable. During the transfer of the mini-greenhouse, the windows cannot be removed, which greatly complicates the process of transporting the structure.

Second option. There are options for covering the mini-greenhouse with plastic wrap. To do this, you need to make a supporting frame from the rails, pull the film on both sides, and press it around the perimeter with any heavy objects. For convenience, it is better to sprinkle one side with earth, and press the other.

The simplest mini greenhouses made of lumber

You will need slats or narrow boards, the amount depends on the size of the greenhouse. The slats are connected at an angle at the top with two studs or self-tapping screws. After making the first element, you need to check its dimensions on the garden, if everything is fine, then you can do all the rest. The first element should be used as a template, so you can achieve the same dimensions for all parts. The lower ends should be sharpened to facilitate driving into the ground. To increase the stability of the mini-greenhouse, it is recommended to tie all the elements with wooden bars on both sides. The structure is covered with plastic wrap, and heavy objects are pressed along the perimeter.

Not a bad option, quickly done, creates normal conditions for the development of seedlings. The rods should have a diameter of 6–8 mm, the length is chosen depending on the width of the structure. Height within 50 cm. Such devices are covered only with foil. The problem is to eliminate sagging of the film. This can be accomplished using several methods.

The distance between the arcs is no more than 50 cm.
After all the arcs are stuck in the ground, several lines of rope or wire are pulled between them, on which the film will lie.

Metal arcs can be bent on a specially prepared template or using any round object of suitable diameter. During bending, it should be remembered that after removing the load, the rods will be slightly unbent.

The bending template is made on a flat surface of suitable dimensions. On it, you need to draw a semicircle with a diameter slightly smaller than the desired width of the mini-greenhouse. After removing the load, the rods will bend slightly, the width of the mini-greenhouse will increase.

Nails are driven in along the drawn arc at the insistence of 4–5 centimeters. In the center and along the edges, you need to drive in another nail, the distance between them and the arc is slightly larger than the diameter of the metal bar. The workpiece will rest against them during bending. To make arcs, you will need some practical experience, it is advisable to pre-practice on unnecessary segments.

Mini greenhouses made of plastic pipes

Plastic pipes up to three-quarters of an inch in diameter are suitable for manufacturing. It is not a problem to estimate the length and number of arcs; difficulties can arise during bending. How to bend them?

Plastic is a very elastic material, it is rather difficult to bend it, it always returns to its original state. If you try to bend it too sharply, the pipe will crack. During the manufacture of arcs, the main task is to remove residual forces, it is they that return the pipe to its primary rectilinear state. To eliminate stress, the plastic must be heated to a temperature of + 100–120 ° C.

Step 1. Prepare a template. Drive several nails into a wide board along the desired arc; to prevent the pipe from straightening after removing the force, you need to drive in additional persistent nails along the edges.

Step 2. Insert a piece of pipe of the required length into the template and bend it into the template.

Step 3. Heat the plastic. This can be done with a construction industrial hair dryer or boiling water. You need to work with a hairdryer carefully, do not allow a situation so that the plastic begins to melt. Work, of course, takes experience. It is easier with boiling water, but it does not allow the pipe to be heated to the required temperatures; it will flatten quite strongly after being removed from the template.

Step 4. After heating, the arc should cool completely in the template. Take it out and check the effect. If necessary, you can repeat the heating of the material and again soak in the template until it cools completely.

To make plastic pipes easier to enter the ground, the ends should be cut at an angle. You can use a hacksaw for metal or a circular grinder with a disc for cutting metal.

To increase the stability of mini-greenhouses made of plastic or metal arcs, you need to install inclined supports on both sides. For these purposes, any pieces of metal or lumber are used.

Mini greenhouses are used for growing seedlings, capricious houseplants, greenery and vegetables. Their design is very diverse - from small greenhouses, which come complete with cells for seedlings, to compact buildings at their summer cottage, equipped with irrigation and heating systems.

The variety of shapes and sizes of mini-greenhouses gives room for the gardener's imagination, however, in order to choose the most suitable design, you need to know its purpose and features.

According to their purpose, all mini-greenhouses can be divided into several types:

for germinating seeds and young seedlings;
for indoor plants requiring special treatment;
home greenhouses for seedlings;
summer cottages, early greens and vegetables;
compact capital greenhouses of small size for growing any crops.

Mini-greenhouses and greenhouses can be equipped with local heating, lighting and ventilation. The use of these structures makes it possible to guarantee the growth of capricious heat-loving vegetables and flowers, to accelerate the germination of seeds and the growth of seedlings, and also to bring the fruiting period closer by 1-2 weeks.

Mini greenhouses with seedling cells

If the mini-greenhouse is designed for accelerated germination of seeds, the easiest way is to purchase ready-made mini-greenhouses with cells for seedlings.

They consist of the following elements:

tray support;
insert - cells for planting seeds;
transparent high cover.

In such greenhouses, the seeds germinate quickly, the seedlings immediately start growing, they get sick and rot less. After planting the seeds, the greenhouse is placed in a dark, warm place, and when shoots appear, they are placed under a lamp or on a windowsill. The lid of the mini-greenhouse must be lifted 1-2 times a day for airing.

Their purpose is to create a composition of moisture-loving capricious indoor plants. As a rule, decorative mini greenhouses are compact and easily fit on a windowsill, shelf or table. You can make them from glassware or an aquarium.

Drainage, a layer of fertile soil is poured onto the bottom of the container, and then the plants are carefully planted. It is better to select slowly growing indoor flowers, cacti, and spurge for these purposes.

Mini greenhouses made of wood and glass

The purpose of such a greenhouse depends on its size: you can germinate seeds, low seedlings in it, and also place indoor plants there. You can make a greenhouse with your own hands from wooden slats and glass or assemble a ready-made set purchased in a store. The illustration shows the step-by-step technology for assembling a mini-greenhouse from IKEA.

You can make a similar greenhouse yourself, after calculating the dimensions and completing a sketch.

The first stage is making the bottom of the greenhouse.

With the help of a cutter - a drill bit - the grooves for the glasses are selected from two adjacent sides.
The slats are sanded with sandpaper or a special attachment.
The slats are cut to size at an angle of 45 ° at the joints.
Grind the ends and joints.
Prepared slats are treated with an antiseptic or waterproof stain.

Indoor mini-greenhouses for seedlings

The described greenhouse designs are good, but too small to grow seedlings for the garden season. Growing plants require space and good lighting, so greenhouses in the form of racks or boxes are more suitable for them.

A greenhouse in the form of a rack is good because, with a large capacity, it takes up little space, it can be easily transferred to a balcony or an open terrace, and in the summer it can be taken to the garden. The disadvantage of such a mini-greenhouse is poor lighting conditions. When growing light-loving crops, backlighting using LED or fluorescent lamps is required.

The greenhouse frame is usually made of metal; you can use a drywall profile. The shelves are made of a metal lattice or thin sheet metal, or of moisture-resistant plywood, painted in several layers with enamel. From above, the greenhouse is covered with a cover made of plastic wrap or covering material.

A greenhouse in the form of a box made of wood and polycarbonate or glass is convenient when good thermal insulation and natural light are required. Such greenhouses, as a rule, are made mobile or portable.

The sizes of mobile greenhouses are different - from small ones for growing early greenery to large ones, which include all the seedlings for the summer season. For a day, such a greenhouse is taken out in the sun, and in the evening it is removed to a warm room.

A greenhouse can have several tiers, as well as built-in lighting and ventilation systems. The walls of the box-greenhouse are most often made of glass.

The disadvantage of a box-shaped greenhouse is that it is bulky and takes up a lot of space. If you are going to use such a greenhouse only for growing seedlings in the spring, it is better to make the structure collapsible.

Details of a collapsible mini-greenhouse for seedlings:

1 - front wall, dimensions 2620x710 mm;
2 - back wall, dimensions 2620x800 mm;
3 - end walls, 2 pcs., Dimensions 720x710 / 800 mm;
4 - hinged cover, dimensions 2620x806 mm.

All parts are made of a 40x40 mm bar, covered with an antiseptic and varnish or waterproof stain. Studs M12-M16 are used as legs that secure the greenhouse in the ground. The greenhouse is covered with foil or sheathed with polycarbonate. The manufacturing technology of a collapsible greenhouse-box is shown in Table 1.

Table 1. Greenhouse-box for growing seedlings.

Steps, photo	Description of actions
	Workpieces are cut from the bar according to the specified dimensions (the height of the rear wall racks is indicated in brackets). Connect them in a frame with self-tapping screws for wood or by connecting a through thorn. To strengthen the structure, corner braces are installed. From the end sides, grooves are selected according to the drawing for installing furniture hangers and through holes are made for fixing pins Ø8 mm. Install furniture hangers on self-tapping screws.
	The greenhouse cover is made according to the drawing similarly to the walls. The jibs are secured with a thorn-groove connection, having previously selected the grooves by ½ the thickness of the bar. The connection is glued with wood glue.
	The side walls are assembled into frames in accordance with the drawing. The bar is attached to the joint through a thorn with glue or self-tapping screws. Screws with a semicircular head are screwed in from the sides of the end walls, 2 pieces on each side of the wall. The size of the head must be suitable for the furniture hanger. The screw is not tightened by 3-5 mm. The location of the screws is determined locally. Also make Ø8 mm holes for the fixing pins, marking the position in place.
	Greenhouse assembly sequence: install the front and rear walls on a flat surface at a distance equal to the width of the end walls. Screw heads are inserted into furniture hangers and clicked into them by pressing from above. The walls are fixed with pins by inserting them into the through holes.
	The greenhouse cover is fixed using special home-made strips, the drawing is shown in the figure. For the greenhouse, you need to make 4 strips. They are attached to the back wall and lid according to the drawing with self-tapping screws, cutting into the wood to the thickness of the metal, and fastened together with bolts and M6 nuts.
	The legs are necessary when using the greenhouse in the country, when installing it on the ground surface. They are not needed for home use; it is enough to place the greenhouse on a flat surface. The legs are made from M12-M16 studs. Holes of the required diameter are drilled in the lower bars of the front and rear walls. The hairpin is secured with nuts on both sides, using enlarged washers so as not to push through the wood.
	The greenhouse is covered with foil or sheathed with polycarbonate. The film is attached through a thick tape using a furniture stapler. For the installation of polycarbonate, self-tapping screws are used.
	The design allows you to quickly disassemble the greenhouse. To do this, fold the top cover back 270 degrees, remove the pins, remove the end walls from the suspensions and unscrew the legs. Disassembled and packed, the greenhouse has dimensions of 2620x800x200 mm.

Wall-mounted suburban mini-greenhouse

The greenhouse is attached to the southern wall of a house or an outbuilding. You can install it on the south side of a solid fence, in this case it is recommended to insulate the wall. An extension greenhouse can be very small and resemble a shelving, but the main difference is that you can go inside to care for plants without causing a sharp cooling of the air.

The greenhouse frame is made of a galvanized metal profile. Shelter - glass, film or. Racks or shelves are mounted inside. For ventilation, use a door or install additional vents in the roof.

Not all gardeners like polycarbonate greenhouses and foil, which some say are not attractive enough. And for those who value not only functionality, but also beauty, there are.

Portable mini greenhouse with convertible top

Such a greenhouse is convenient to use for growing greens in boxes and hardening seedlings. If the bottom is not covered with a net, the greenhouse can also be used for thermophilic plants planted in the ground, as protection against recurrent cold and frost. The advantages of the greenhouse are good illumination and easy access to all plants, as well as the low cost of materials.

The assembly order is shown below.

A rectangular box 15-20 cm high is assembled from an edged board. The bottom of the box is sewn up with a metal mesh.
They make a frame of the same size from a wooden block or lath. The corners are reinforced with ties.
Grinds all surfaces, removing burrs.
5 identical arcs of the required height are made from a PVC or MP pipe. Fix them in the upper frame with half-couplings.
The half-couplers are carefully pulled to the frame so that the pipes are rigidly fixed.
A rare metal mesh, for example, a masonry mesh, is pulled over the pipes.
The upper frame is attached to the end of the box using door hinges. Chains or strong twine are attached to hold the roof open.
Cover the top and side walls of the greenhouse with a covering material or film.

Small capital greenhouses

Such mini-greenhouses differ from ordinary ones only in small sizes - up to 10 m 2. They are installed on a foundation, equipped with beds or shelves, as well as a ventilation system (sometimes heating).

The greenhouse frame can be made of wood, shaped pipes or galvanized profiles. The coating is most often a film or polycarbonate - this makes it possible to lighten the structure and use a foundation from a bar.

Note! Small greenhouses quickly warm up in the sun or from a heating system, so they are often used for growing seedlings in spring.

Manufacturing technology of a garden mini-greenhouse

The mini-greenhouse is made of wood and covered with honeycomb polycarbonate. The size of the greenhouse (1.65 x 3 m) allows you to grow seedlings, flowers or vegetables in it for food. A door is intended for maintenance of the greenhouse and airing; if desired, you can install a window or a fan on the back wall.

Necessary materials:

dry board 50x100 mm;
bar 50x50 mm;
ridge strip - a board with machined ends;
textured wood coating;
cellular polycarbonate 4 or 6 mm;
, and ridge profile for polycarbonate;
mounting angles and plates;
self-tapping screws for wood and polycarbonate.

To assemble the greenhouse, you will need an ordinary carpentry tool: a hacksaw or jigsaw; a screwdriver, tape measure, square and level, and a brush or roller for painting.

The greenhouse is placed on a brick foundation. Waterproofing is performed on top of the foundation with roofing material. Anchors fixed in the masonry are used to fasten the lower strapping to the foundation.

A - side walls;
B - frontal wall;
C - rafters;
D - ridge bar;
E - door;
F - back wall.

Step 1. Two identical side walls are assembled from a 50x100 mm board according to the drawing.

Saw out the boards of the lower / upper strapping - 3050 mm and 6 racks of 1524 mm on each side. Workpieces are laid out on a flat surface and connected to mounting corners and self-tapping screws. The corners are attached on both sides of the rack.

Mark the mounting holes for the anchors in the lower trim planks and drill them. Install the side walls in place, secure with nuts and, if necessary, cut off the excess anchor pins.

Growing seedlings is not easy. Plants need the right microclimate to grow and develop quickly. That is why gardeners install mini greenhouses on their plots.

There are different types of such structures. Since the imagination of folk craftsmen is limitless, you can make a simple structure yourself. This requires both ingenuity and improvised means. If you need to make a durable product for outdoor installation, polycarbonate or agrofibre may be needed.

Why do you need a mini greenhouse

A mini-greenhouse is sometimes needed only for a garden or a summer cottage, but also in an apartment. Whimsical and heat-loving plants can be planted in it. Such a structure has several obvious advantages:

protection from wind, draft and rain;
optimal microclimate;
the seedlings gradually get used to the conditions of the street;
it is convenient to care for plants;
ease of installation.

It often happens that the small area of the site does not allow you to place a full-fledged greenhouse on it. In a small area, you can install a compact and practical mini greenhouse. Sooner or later, the grown seedlings will have to be transplanted into open ground conditions, but the greenhouse will always become a cozy home for other plants (greenery, carrots, beets, flowers). They don't need a lot of space: they feel great in a mini greenhouse too.

Varieties of mini greenhouses

There are many varieties of mini greenhouses. They can be of different shapes and sizes.

Mini greenhouse at home

As a rule, it is placed on a windowsill, and crops begin to grow in early spring. Some plants are sown in winter as well. The main purpose of the application is to accelerate the development of plants so that in spring or summer they can be planted in open soil.

In appearance, home buildings are no different from street buildings, except for their dimensions. Reduced copies of street models on an arc frame are very popular. There are greenhouses consisting of several tiers or floors. As a simple option, use ordinary wooden boxes covered with polyethylene film.

Portable plank construction

This is a wooden box without a bottom, but with a film or glass lid. The box can be moved anywhere at any time. It is used when crops planted in the ground are threatened by spring frosts. Vegetables, berries and flowers take root well in an outdoor portable greenhouse.

Recessed or Belgian greenhouse

To create a Belgian greenhouse, you will need to dig a trench and reinforce its walls with piping. A garden bed with fertile land is made out in the trench. The structure is covered with a lid. The material for it is a film or polycarbonate. Fertile soil is an ideal heat insulator, but if necessary, you can additionally insulate the structure with biofuel.

Advice!

Belgian greenhouses are most often made with pitched roofs. This saves space on the site.

Mini greenhouse "Butterfly"

The Butterfly model got its name from the design features of the doors. If both of them are fully open, the structure becomes like a butterfly with spread wings. Since the greenhouse flaps open on both sides, it provides easy access to the plants at any time. The size of the "Butterfly" can be anything, but most often these are attractive small-sized structures.

Greenhouse "Snail" or "Breadbasket"

This little greenhouse exactly repeats the design of a real bread bin. Its semicircular sash is fully raised up. At the same time, it slides behind the fixed part of the semicircular roof. Plants are easy to care for, and the structure does not take up much space.

Balcony greenhouses (shelf)

For the manufacture of a "shelf" greenhouse use an old cabinet or rack. The wall from the back is removed from the cabinet, and the resulting void is tightened with polyethylene. A door is equipped in front, which often looks like an ordinary piece of film. The door is fixed with a rail or magnets. Such a greenhouse resembles a shop window. It is transparent, and this allows you to constantly observe the plants. It can be used to grow greens and vegetables all year round.

Wall mounted mini greenhouse

It is always placed against the wall of a house or outbuilding. The greenhouse is compact and can be an excellent solution when the suburban area is very small, and it is impossible to place even a small "Butterfly" on it. This design has a pitched roof. It will have to be regularly cleaned of snow.

Important!

For a wall mini-greenhouse, you need to choose the southern wall of the house so that the plants receive enough heat and light.

Mini greenhouse from a plastic bottle

You can make several mini-greenhouses from ordinary bottles if you don't want to buy wooden boxes and fiddle with plastic wrap. You will need a 2 liter plastic bottle. A rectangular hole is cut into it. The resulting door is bent, then the bottle is filled with earth and plant seeds are planted in the container. The greenhouse door must be tightly closed, fixing it with tape. As soon as the seeds germinate, airing can be started to get more oxygen for the plants.

Mini greenhouse from an old barrel or can

Do not throw away your old can or barrel. They can be used to make an excellent greenhouse of a classic shape. To do this, cut several holes in a barrel or can. The holes should be made so that it is convenient to care for the seedlings. After the holes are ready, a dense material is attached on top in the form of a tarp or double polyethylene. Four screws will be enough for fastening. It is better to use a tarp because the plastic will quickly fray from the wind.

Mini greenhouse from window frames

This is a heavy structure, so you need to build a foundation for it. Frames must be carefully prepared before installation. They are cleaned of old paint and covered with stain or drying oil. To make the frame, you need one rack and two straps - the lower and the upper. It is better to make the floor concrete, with a layer of waterproofing, and the roof - gable. Despite some difficulties, the advantage of a product made from window frames is that its basic elements can be obtained free of charge.

Advice!

Frames should be matched to the same size and shape, otherwise it will be difficult to fit them together during assembly.

Materials for making

When building a simple mini-greenhouse, the following materials are used:

plastic;
metal profile;
wood;
polyethylene film;
polycarbonate sheets;
agrofiber;
glass.

An arched greenhouse needs a flexible frame. Frame arcs are made of plastic or metal. Among gardeners there are craftsmen who manage to make a semicircular frame from wood.

The tree looks very nice, but it is prone to decay. Metal or plastic looks more prosaic, but they are more practical. Their disadvantages are that the plastic bends, and the metal is subject to corrosion. When using metal, the situation can be corrected: treat it with an anti-corrosion agent and paint it. Unlike metal, plastic does not corrode, but it is more fragile and costs much less. Most often, a box for portable models is made of wood.

Now you need to deal with the materials that are used for cladding. A good material is agrofiber. It transmits light and creates a good microclimate in the greenhouse. Agrofibre is very dense and porous, has the ability to pass moisture, and keep heat inside. The material is easy to wash, and if stored carefully, it will last for many years.

Often in vegetable gardens you can see greenhouses covered with polyethylene of different thicknesses. The film is easy to use. It creates a microclimate for plants no worse than other materials, but it cannot be called durable. In bad weather, especially in strong winds, it breaks quickly, so it needs to be changed every two to three seasons.

Is a material that many gardeners like. It is lightweight and durable. It can be used to cover both a small greenhouse and a full-fledged greenhouse. Working with polycarbonate is a pleasure: it is easy to cut and process. It can be given any desired shape. Products from it look beautiful and neat.
