Even the smallest crack or gap in a window can let in a stream of icy air in winter.

From cling film, cut a few pieces of the required size, stack them one on top of the other to create one thick layer, and glue to a place on the window where it blows hard.

2. Do not let the brushes and rollers dry out.



If you have painted, for example, a wall, and are going to continue painting the next day, then to keep the brush and roller soft, wrap them with PVC film (food wrap). The same can be done with a can of paint.

What is there to think! - you can answer. - I'll go to a hardware store, buy a film, and that's it! Hmm, which one exactly?

Full transparency

There are many types of film now. I will not dwell on ordinary polyethylene: everyone knows it. An excellent inexpensive material, suitable for both small shelters and huge greenhouses ... However, only new for now. Some films and the season do not stand up! So the garbage dumps around all the gardens are covered with dirty rags, polyethylene decomposes extremely badly. Maybe, after all, look for a film a little more expensive, but better, so that it can serve at least a few years?

So, what can the industry offer us, summer residents?

1. Reinforced films in which a synthetic mesh is fused into polyethylene. Of course, it is much stronger than usual: it can be pulled over a large greenhouse and not be afraid of either wind or hail. The only “but” is that such films do not come to the fore mechanical strength, but resistance to solar radiation. The worst samples crumble into dust after 2-3 seasons. Apparently, this is why the data on the durability of the reinforced film differ: from 2 to 7 years.

2. Polyethylene films with additives. Their range is very large, but not all supplements are "equally useful," as they say in advertising. Definitely valuable - the introduction of stabilizers into the composition of the material, which protect polyethylene from the damaging effects of sunlight. Such films, although noticeably more expensive than usual, serve many times longer than it (3 years or more). Most often they are pinkish or orange in color, but this is not necessary.

A more complex, but also very useful component of modern films is the phosphor additive. It converts part of the sun's rays from the ultraviolet spectrum into more useful red for plants and infrared radiation. As a result, the processes of photosynthesis in plants are more active, and the yield increases markedly. Such films are called light-transforming. But, when purchasing one, do not forget that it must also be stabilized, otherwise all its advantages will not please you for long.

A film with phosphor additives can be checked by shining an ultraviolet lamp through it. The light from the lamp should change to red.

3. Bubble polyethylene film. We usually meet with her when unpacking something fragile. But such a film is also produced for greenhouse purposes: after all, it transmits enough light, and in terms of outstanding thermal insulation properties, only thick polycarbonate can be compared with it. I think that a small greenhouse or a sunken warm bed, covered with bubble wrap, will be useful for every gardener to get the earliest greenery, as well as seedlings of cabbage, lettuce, asters and other cold-resistant crops. Although it is hardly possible to seriously talk about its durability (with the exception of special varieties).

4. Non-PE films (PVC and others). In my opinion, this is one of the best options. As a rule, they are "rubber" to the touch and have a yellowish or pinkish tint. The strength and durability of these films is beyond praise! I know cases when they kept for 6 years or more without being removed from the greenhouse, and it even happened that the greenhouse itself fell under the weight of snow, and the film - at least henna. Yes, and with stabilizing and light-transforming additives for such films, everything is usually in order. The only downside is the price.

Stress Protection

Or maybe it’s better to replace the film with a non-woven covering material altogether? It is needed both in summer and in winter, and it serves quite a decent time - savings, however!

Nonwovens, of course, have a lot of advantages. They "breathe" and pass moisture well, the plants under them do not overheat. "Non-woven fabric" (especially thick, 40 g / m 2 or more) has better thermal insulation properties than a film, and allows you to more reliably protect plants from frost. Well, and thin (17-40 g / m 2) - although not so warm, it is light, and it can be placed on plants even without a frame. But, alas, from experience, non-woven materials are still more of a material for temporary (including winter) shelters, and not for long-term growing plants. Summer residents of central Russia, who tried to cover stationary greenhouses with them (of course, we are talking about dense varieties of “non-woven” - the thinnest one is not strong enough for this), faced with the fact that their favorite cucumber-tomatoes are pretty lacking in light. The advantages of non-woven materials in hotbeds and greenhouses were truly appreciated only by the southerners, who have nowhere to put the sun. But this does not mean at all that they are not needed: a stock of "non-woven fabric" to protect the garden from spring frosts, "safety net" for sowing and planting seedlings, as well as for sheltering capricious plants for the winter is worth having for every summer resident.

On a note

Another extremely useful property for greenhouses is the so-called “hydrophilic surface”, which modern polymer films can often boast of. In practice, this means that the moisture condensed from the air does not collect on the film into drops and does not fall on the leaves in the form of cold dew, but “sticks” to the surface and gently flows down the walls. Plants in the greenhouse will get sick much less!

Marking secrets (GOST 10354-82)

M- durable film used for the manufacture of transport bags and other packaging.

T- film for the manufacture of technical products, protective shelters, packaging;

ST- dyed or unpainted, stabilized film for greenhouses, greenhouses and other agricultural facilities;

SIC- a stabilized film with an IR radiation adsorbent for covering greenhouses and other agricultural structures, providing an increased greenhouse effect;

CM- for mulching and other similar purposes; uncolored, carbon black-stabilized film (dark);

B, B1- special films for use in land reclamation and water management construction;

SC- film for use in the preservation of feed, etc.; unstabilized;

H- film for the manufacture of packaging and household products; dyed or undyed, stabilized or unstabilised.

It is easy to see that films labeled ST, SIK and separate - N are suitable for greenhouses and greenhouses.

About what for agriculture transparent polyethylene film is used, everyone knows. This is the cheapest and most affordable material for sheltering plants from rain, wind, hail and frost, for the construction of temporary greenhouses and stationary greenhouses.
Why do you need black greenhouse film? What benefit can it bring to the gardener?

Made of high-pressure polyethylene stabilized with soot, the black greenhouse film differs from the transparent one not only in color, but also in its properties, and, accordingly, in the field of application. As usual, this film is produced in sleeves wound into rolls with a width of one to three meters.
After cutting one of the sides and unfolding, the material becomes twice as wide.

Advice. The polymer is easily cut along the fold with a knife or open scissors. But if you need to unroll a very long sleeve, do not rush to unwind the roll - just cut off one edge with a hacksaw or a fine-toothed circular saw.

To meet any consumer demands, the film is produced in different thicknesses: the minimum is 40 microns, the maximum is 200 microns. But even the thinnest practically does not let sunlight through.
It is this property that is actively used in agriculture and in particular in industrial and household greenhouses.

The price of a black film is much lower compared to other varieties of this material, and the benefits from its use are very tangible, so its use can be considered profitable and practical.

Methods of application in greenhouses

In this chapter, we will not talk about all the applications of the material, although there are many. This includes construction, land reclamation, trade, and agriculture.
We are interested in how it is used in greenhouses and greenhouses. It is clear that black is a completely useless structure, since not a single plant will grow in complete darkness.
However, this property, as well as the ability of the material to accumulate heat and not let moisture through, can be used for good.

Mulching

Mulching is the covering of the soil in order to regulate its temperature and humidity characteristics. This method has been practiced in agriculture for a very long time, but until recently, materials of organic origin served mainly as mulch: humus, peat, straw, dry leaves, mowed and dried grass, sawdust, tree bark, etc.
Today, black film for greenhouses is becoming more and more popular and in demand for this purpose. Its only drawback compared to organics is that it does not improve the composition and structure of the soil, but there are quite a few advantages.

For reference. Organic mulch at the end of the season after harvest is embedded in the ground and rots in it, turning into humus and improving its nutritional properties.

What are these benefits:

  • Stopping the growth of weeds. The absolute opacity of the film does not allow the seeds and roots of weeds remaining in the ground to develop. Their absence has a beneficial effect on the growth of cultivated crops and frees gardeners from regular weeding;
  • Under the black film, mold does not form, which cannot be said about organic mulch;
  • Harmful insects do not start in it, and the impenetrable canvas protects plants from pathogens that are always present in the soil;

  • The film retains moisture better under it, preventing it from evaporating from the surface of the earth, forming a dense airtight crust. If earlier you had to loosen the soil “petrified” after several waterings under tomatoes or cucumbers with your own hands, now you can forget about it.

Other advantages of film mulching include a reduction in water consumption for irrigation and the fact that after it or after rain, the leaves and fruits remain clean, not polluted by the ground.
In fairness, it should be said that it is even more effective to use not a film, but a black spunbond. Possessing similar abilities, it is more durable and durable, besides, it allows water to pass through itself, allowing you to water the beds in any way convenient for you.

Soil warming and warming

Possessing absolute opacity, the black greenhouse film nevertheless attracts the sun's rays to itself, while quickly heating up and transferring heat to adjacent surfaces.
This property is used in greenhouses in the following cases:

  • For early warming up of the soil. As you know, the soil warms up longer than the air.
    In early spring, under a film or other cover in a greenhouse, it can already be quite comfortable for plants, but the earth at this time is still very cold, and at some depth it is completely frozen. To speed up its thawing and heating, they spread a black film, under which these processes go faster.

  • For warming beds. Today, many gardeners have adopted the technology of growing plants in high beds, fenced on all sides.
    If these sides are wrapped with a black film, during the day it will heat up, and at night it will give off heat to the ground.

How to use mulching film

If it is enough to simply spread the film on the ground to warm the soil, pressing its edges, then another instruction must be followed for use as mulch. Firstly, you first need to prepare the soil by adding all the necessary mineral and organic fertilizers to it, carefully digging, leveled.
Then they are made, the width of which depends on the type of crops planted on it. The film is laid on top after careful watering, preferably a few days before planting - so that the ground under it warms up well.

Advice. Choose a material of suitable width so that it does not have to be cut or laid on one bed with two canvases.


Film thickness is important. If the thinnest (40-50 microns) is used to warm the soil, then thicker, stronger and more durable material is taken for mulching.
If it will serve no more than a year, a thickness of 60-80 microns is enough, but if you plant a perennial crop, for example, strawberries, it is better to give preference to a material with a thickness of 100-120 microns. Thicker canvases are not efficient or economical to use, their scope is - construction and other industries.
If you watch the video presented in this article, then even without a description you will understand how to proceed. Everything is very simple: in the film spread on the bed, cuts are made at specified intervals with a sharp knife - cruciform or in the form of the letter V.
By turning the corners inward, you will get square or triangular holes..It is clear that the distance between them is selected depending on what you will plant in the garden, how much free space is required for one adult plant.

Advice.
To speed up the process, especially in the case of mulching over a large area, you can fold the film several times and burn it through with a hot object, obtaining several identical holes at the same time. Then spread it on the bed.

Seedlings are planted in these holes or seeds are sown. To facilitate your work, you can equip a drip irrigation system by connecting a tube with a dropper to each plant.

Conclusion

As you can see, greenhouse black film can bring a lot of benefits if you know how to use it correctly. All the methods described are suitable not only for greenhouses and greenhouses, but also for growing plants in open ground, where the problems of watering, loosening and weed control are even more relevant.
