In our climatic zone, no cottage is unthinkable without greenhouses. Here are just a glass greenhouse is very heavy and can break, film coating or nonwoven covering material rush to the end of the season, sometimes earlier.
Modern polycarbonate greenhouses do not have these drawbacks, but they are very expensive. Simple alternatives to traditional greenhouse coverings are plastic bottles.
Garbage for the device of greenhouses
Organized waste recycling in our country is just beginning to gain momentum, so large cities are surrounded by huge landfills. The lion’s share of garbage produced is plastic bottles. What we used to send to the urn, can still serve a good service. Conventional plastic soda bottles can be the basis country greenhouse.
This greenhouse has many advantages. The most important thing is its cost. This is one of the most cheap options. It is much stronger than plastic film. Lightweight, unbreakable. It is always easy to repair, replacing the damaged item. Fine keeps warm.
There is a serious disadvantage. It will take some time to collect the required amount. bottles. And you need a lot of patience to assemble the structure. True, all this will pay off handsomely when you are proud to contemplate your offspring and catch the intrigued glances of your neighbors.
You can bottle the bottles in a short time. in places of mass recreation. On the beach or on a city holiday. You can connect to the collection of their friends and neighbors who will be interested to participate in an unusual experiment.
What can be used for the frame
For frame almost any material is suitable. You can choose metal, wood or plastic.
Metallic profile will stand for many years. Metal will provide greenhouse strength and durability. All that is required is to only paint it from time to time, and wash it off from contamination at the end of the season. But to build this frame requires some skills with metal, special tools. The most convenient metal carcass cook.
Tree as the material impresses with its availability and cheapness. It is quite easy to work with him. With proper design, the frame will also be strong enough to withstand wind and snow loads.
Each 
year the wooden base will have to process special antiseptics.
The service life of such a frame will be comparable to the bottle cover. Most likely, you will have to change the coating and frame at the same time.
An alternative to the traditional material is the frame from PVC pipes. They are very light and allow you to make a greenhouse of any shape: not only single or dvukhskatnuyu, but also arched. Perhaps such a framework will require more careful reinforcement to withstand any bad weather.
Preparatory work
Before the construction of greenhouses from plastic bottles it is necessary to develop a design for the future structure. In the drawing, all dimensions are applied, and it is calculated how much material is needed. Must be taken into account stiffening ribwhich will make the greenhouse more durable.
At the preparatory stage, you need to collect a sufficient number of bottles. Not less than one greenhouse 400-600 pieces. Bottles try to take the same size, preferably 1.5 and 2 liters. Carefully removed label.
To make it easier to remove the paper label from the bottle, soak the empty container in warm soapy water for several hours, and then rub it with a metal brush.
When everything is ready, choose a place for future greenhouse. The place of construction should be well lit. 
It is better to have a greenhouse from the southwest side from other buildings and tall trees. For uniform heating, orient the building from east to west.
Greenhouse put on prepared foundation. The simplest option is to make a base from a wooden beam, which is placed directly on the ground. It is suitable for light wood or plastic construction.
For the construction of the metal frame is better to make a major foundation. A trench is dug along the perimeter of the greenhouse. 25 cm in width to the depth of frost penetration, to 50-80 cm.
A sand and gravel pad of 10 cm is laid on the bottom. Formwork is made and cement is poured. The foundation is made flush with the ground, and about 5 rows of masonry are laid on top.
By the same principle, you can make a column foundation. The distance between the columns is set to 1 meter.

Master class on the creation of greenhouses from plastic bottles
Resourceful gardeners have come up with several ways to build greenhouses from plastic containers. The main ones are: greenhouses from whole bottles or plates. Let us consider both options.
Greenhouse from whole plastic bottles
For such a greenhouse, the bottles are put one on one in the form plastic log. Inside the air is preserved, so this greenhouse provides good thermal insulation.
To make the walls and roof of the greenhouse in this way, it is necessary to cut off the bottom of each bottle at the place where the bottle begins to expand. Thus, the hole will be slightly smaller than the maximum diameter of the bottle. Then they sit down one on one as tightly as possible. In the middle for durability, they insert a thin rod or stretch the string.
The finished unit is installed in the wall vertically or horizontally, securing with screws. In the same way make the roof.
Plastic greenhouse
For this design it is necessary to cut each bottle. If you look closely, there are two transverse lines on the bottle that separate its flat part and one longitudinal seam. On these lines is cut flat rectangle (see fig. 1 and 2).
For cutting it is convenient to use a stationery knife or simple scissors. Rectangular plates are sorted by size: from 1, 1.5 and 2-liter bottles.
To align the workpiece can be placed under the press. But this is not necessary, they will even out in the finished product. It is undesirable to iron them with a hot iron, because the plastic is strongly deformed by temperature.
Rectangles are stitched together with overlapping cloths no more 150 cm (otherwise it is inconvenient to work). From the edge of the plate recede a little more 1 cm (Fig. 3). It is important to make this stage as accurate as possible so that the shelter is tight. There are several ways to staple:
- on a sewing machine, if not sorry;
- using a furniture stapler;
- with the help of sewed.
Let us consider the last method in more detail.
- Two identical plates fold the short sides with an overlap of 1.5 cm.
- Pierce them with 3 hot spots with a hot awl. In places of a puncture sheets will melt and stick together.
- As a thread for stitching, you can use a thin wire, cord thread. And the best of the remaining bottles cut into thin long strips of 2-3 cm wide. And stitch them.
- Tie a knot and thread the thread through the holes. Tie knots at the other end.
- Repeat the same procedure with other blanks. To make cloths of the necessary sizes, proceeding from dimensions of the greenhouse. It is necessary to provide a stock of 20 cm.
- For convenience, a stool is placed on two stools from the refrigerator. So sew much easier.
It is possible to cut long thin ribbons from bottles not only with scissors, but also with the help homemade bottle cutter. A simple bottle cutter by lawyer Egorov is made from a piece of ordinary aluminum channel. A plastic tape is always useful in the household as a strong shrink rope.
Finished canvases are fixed to the frame with the help of slats and screws or nails with wide caps.
Canvas need good to pullso that it does not sag. Also the roof and the door are covered. Since the greenhouse is very warm, it is necessary to provide air vents for airing.
Using bottles of different colors, you can adjust the light inside the greenhouse. And decorate it with some kind of ornament. But dark bottles are better not to abuse or use them to cover the north wall. This is especially true of the northern regions of the country where the sun is not enough.
But in the south, where the sun is in abundance, colored bottles will help keep plants from burns.
Greenhouse from plastic bottles is obtained enough solidto withstand the weight of snow in winter. The main thing is to have a strong frame. With a quality build, this shelter will serve not less than 10-15 years. At the same time the cost of consumables minimal, since the main part is literally made of garbage. It is only necessary to show a little diligence.
