Reviews and tests of products

St. Petersburg State Agrarian University 2012.
... Observations have shown..
... night temperature under the film was 2-3°C higher. At 10 o'clock the temperature under the film was  1-4°C higher due to higher light transmission. During the day, the heating under the film was 2.7°C with a maximum temperature of 34.3°C, under the polycarbonate 2.1°C and 31.0°C...
... humidity  during the day was  на 6-12 % 6-12% lower than under polycarbonate...

Summary:

1. In greenhouses under the film SVETLITSA TM  more favorable climate for plants is formed. Plants are compact, and fruiting begins earlier due to a more significant influx of solar radiation.
   
2. Previous experiments have shown that the film SVETLITSA TM - can be used in greenhouses for 7-8 years, slightly dusted at the end of the season, and restores translucency after winter.
3. After 3-5 years of operation, polycarbonate loses more than half of its transparency in greenhouses; it is mainly used as a side fence as insulation.

We have been buying SVETLITSA™ GROUND mulching film since 2016, and we are very satisfied with the quality of this product. The film is strong and perfectly stretches. It is easy to install, the film is well stretched, and takes the shape of the beds.

In our experience, this mulch film withstands winters very well, lies for several seasons without losing its properties, it does not crack or deform. Compared to previously used films, we can emphasize the strength and durability of the SVETLITSA™ GROUND film.

When selling seedlings, we always recommend using SVETLITSA™ GROUND film to our customers. Most importantly, those who use it are just as satisfied with the quality. We express our gratitude to your production for excellent and high-quality products.

Sincerely, Elena and Sergey Borisov.

We have been using photo-degradable film for grafting of " Shar" company for about five years. The film is of good quality, elastic, does not tear when tying grafts. When cutting by hand (i.e., with a knife) on the edges of a strip of film, there are always invisible "to the eye" micro-irregularities, along with ordinary polyethylene film and films from other materials usually rip.

With grafting film, this problem does not arise because it is elastic and, at the same time, strong enough. Thanks to its ability to break down in the light, this film eliminates such a time-consuming operation as removing the strapping.

If you tie the grafts correctly, i.e., tie them as tightly as possible, but not stretching the film to the end (it largely depends on the width of the tapes), then the seedling, even with strong growth in a month, does not get overstretched. Just for this month, the film breaks down (in spring grafting).

The only disadvantage of this grafting film is its stickiness. When the tapes are collected in a bundle, they sometimes stick together. But the company "Shar" successfully tries to get rid of this disadvantage.

Now "Shar" company cuts grafting tape into spools of the required width. In our opinion, the best width of grafting tapes for a fruit nursery is 20 mm. The cutting width depends on the thickness of the rootstock and grafting. The best film thickness is 100 µm. A thinner film can be suitable for thin rootstock, it is more elastic but at the same time loses a lot in strength.

Our nursery is very grateful to the company "Shar" for paying attention to such an area of agriculture as nursery farming and producing an excellent film for grafting. We are not aware of any analogs of this film in Russia.
