Phytolamba for plants illumination.

From the end of November and until the end of April, because of the plants of light, there are not enough tomatoes, cucumbers, peppers are not growing and the crop does not give. This occurs even if they keep them with quite comfortable conditions of humidity and temperature on the windowsill. Only vitluf Yes, the bow on the tramp can carry the lack of light, but feel better, if you turn on the light bulb.
Lamps with mirrors.
20 years ago, when electricity cost cheaply, there were enough plants a couple of luminescent lamps to get fragrant Zelents and Tomatoes for the holidays - by February 23, by the New Year. Today, such a luxury can afford mainly farmers and those owners of household plots that grow vegetables for sale, as they have the costs of the backlight pay off harvest. Let me remind you that in winter, an increase in illumination gives 1% the same increases for products. However, farmers are looking for devices to save on electricity. It is not surprising that energy-intensive lamps in the form of spirals are becoming increasingly distribution.

However, it is necessary not only to save electricity, but also compensate for the shortage of sunlight, and those that are important for normal photosynthesis of plants. It is possible to achieve this with phytolamp. Choosing a lamp type and its work mode primarily depend on the biological features of a plant. Once or two types of their artificial irradiation (lights): assimilative and photoperiodic.

With assimilative irradiation artificial light It is added to the natural level of illumination, which contributes to the normal growth and development of plants. To do this, use lamps that provide greater luminous energy density (rays).
Photoperiodic irradiation controls the plant development cycle, and its results are determined by the duration of the lamps in the dark. In this case, it is important to pay attention to the quality (spectrum) of the emitted light of the light.
Modern phytolamby allow you to use both types electric Slows. The highest photosynthetic efficiency (they emit the light closest in the spectrum to the sunshine) have mirror sodium lamps of high pressure. They provide good light output (up to 150 lm / W), uniform and wide distribution of light flux - the plants seem to be bathed in the rays. Moreover, in the lamps with an internal mirror coating (intravenous flask). For example, the DNA3 / Refluch brand, the properties of the reflective layer practically do not change during the entire service life. And since mirror lamps do not require special mirror reflectors, Dimensions of lamps can be small. Such a lighting system gives 15% of light more than tubular lamps with external metal reflectors. Lamps-DNA3 / RefLU 250 and 400 W are advisable to install in polycarbonate greenhouses of the "Perchina" type, "Volga region", "KUMIT" with a size of 3 × 4, 3 × 6 and 3 × 8 gi, skate height 2 m and with one central Walkway between the beds. LAMPS providing the necessary level of illumination (5000-12000 LCs), respectively, the specified size of the greenhouses should be 2, 4 and 6.
It is necessary to place lamps with lamps at an altitude of 1.5 m at an angle of 15-20 ° with such a calculation so that Normal (a beam coming at an angle of 90 °) from the center of the lamp hit the bottom center of the garden (see scheme). If a three-dimensional greenhouse with a length of 8 m and a height of 3 m, for growing in it from autumn to spring cucumbers and tomatoes, it is necessary at an altitude of 2.7 m above the tracks to place 6 lamps of DNA3 / REFLU with a capacity of 400 W with a pitch of 2.5 m.
For the cultivation of these cultures and seedlings in the conditions of a city apartment, a lamp of the DNA3 / RefLU with a capacity of 100 W, which is strengthened in a movable bracket above sill or seedlings. Such a lamp illuminates an area of \u200b\u200b1.5 sq.m.
On a note:

A modern hairdresser or beauty salon cannot do without specialized cosmetology equipment. Cosmetology using various drugs is a promising direction in the work of the salon business and today it is very popular with customers and specialists of the salons, due to the fact that when using cosmetology equipment, a fast and effective result is achieved.

Contemporary beauty salons equipment It is often used in conjunction with conventional techniques, and this allows clients to provide the maximum quality of correction and care programs.

For sale apparatus with one-functional impact, as well as combines having many functions that combine a set of physical methods.

Equipment for cosmetology from the point of view of functional characteristics, the cost of devices and technological capabilities is very diverse.
