LED lamps for seedlings. Lamp for seedlings

Spring is a time of great labor. And not only for people. In the most favorable period, taken away by nature for vegetation, plants also work. They sprout through the "shell" of the seed, break out from under the ground, throw out the first pair of leaves. And they grow, grow up tirelessly.

The main condition for active development for all without exception vegetation is a sufficient amount of sunlight, directly affecting the level of photosynthesis.

And since all gardeners and flower growers are in a hurry with the planting of crops and start growing seedlings in the winter months, the lack of natural sunlight is compensated for by a lamp for seedlings.

Let there be light, or Physics is omnipresent

The usual daylight, which is customarily called white, has a wide color spectrum , which is habitual for visual perception of a person and necessary for the life activity of everything .

If you turn to physics and decompose the beam into its components, you can admire the waves of different colors and different lengths and at the same time not see anything unfamiliar. Everything, as in the well-known count: "Every hunter wants to know ..."

All the colors that make up the rainbow are always proportionally present in the sunlight, and most of them are very necessary for plants for quality development and growth.

In the winter gloomy months, when the light day is too short and can not provide plants on the windowsill with the necessary amount of sun for them, careful owners buy or build their own lamps to illuminate the seedlings. Has included - and on a mini-garden the day proceeds.

Offset towards red and blue. Biological necessity

Although vegetation needs light, not all spectral regions perceive it in the same way. After a lot of research, biologists came to the conclusion that most of the representatives of garden and vegetable flora need the blue and red colors of the spectrum.

Red light positively affects the germination of seeds. When the young stem only rises from the ground, it is in a bent position (almost like a baby in the womb). And that the young plant "understand" that it is already above, and not under the ground, and straighten, red light is needed, which can trigger the process of photosynthesis and growth.

The blue region of the spectrum is responsible for cell division, the appearance of new strong sprouts.

On the yellow and green colors, plants practically do not react - they reflect useless elements of the spectrum from the surface of the leaves.

When installing a lamp to illuminate seedlings, it is necessary to take into account the spectral preferences of vegetation and choose those in which the shift of the spectrum is observed in favor of red and blue.

Room greenhouse needs a light bulb

For all the small size of most modern apartments, a gardener-enthusiast-amateur will always find a place to grow seedlings of your favorite crops. As a rule, this honorable role is assigned to the windowsill.

But even when the window sill is full of light in short winter days (it's time for germination), even at the window, plants do not get the amount of sun that would ensure their active growth and development.

Lack of light has a very negative effect on the condition of shoots: they are weak, languid, exhausted, unnaturally long and always strive to bend down.

To avoid such a dull spectacle, it is necessary to provide plants with a source of artificial light immediately after disembarking them into the ground.

The single seed lamp only manages its function if the illuminated area is small. And if the greenhouse does not occupy the sill, but the whole room? Then there should be a lot of lighting. Although gardener, flower growers and complain that LED lamps for seedlings - a very expensive need, another optimal option for providing themselves with quality "tops and roots" has not yet been invented.

Lamps for seedlings: cheap and useless

The natural desire of everyone who grows seedlings for themselves, is to save. Therefore, kulibins for their own greenhouses come up with a variety of ways to ensure a minimum of costs (energy in the first place) during the growing period.

Lamp for seedlings, made by hand - the first of all known options. It is done elementary: you need to screw into the cartridge any light bulb, even the usual one, with a tungsten filament, to highlight the seedlings and wait for the results.

But such haste in the decisions and actions of positive results, alas, will not.

In order to properly highlight the seedlings, it is necessary to understand the laws of biology, discussed above, and to understand which color spectrum is needed for the plant for vegetation.

Lamp for seedlings can not be simply bought in the department of chandeliers and lamps. It is assigned a function more important than just shining, it must influence the growth processes.

Phytolamps: varieties, characteristics

With all the richness of the choice, only three types of phytolamps are recognized as the most optimal in providing strong seedlings, which means a high yield.

The most popular and popular lamps for growing seedlings:

• Luminescent. Attractive in the price aspect, but consume too much electricity.
• Sodium. Lamps in the middle price segment, the percentage of energy consumption they have lower than in luminescent, but the inconvenient bulkiness and the danger of an explosion from moisture are constraining factors in the choice.
• LED lamps for seedlings. The price of the lamp itself is quite high, but afterwards they bring huge savings, because they are durable (their capacity is 6-12 years of continuous operation) and are not energy-consuming (they absorb electricity three times less than luminescent ones), they contain "favorite" plants Radiation - blue and red.

When plants need extra light

Not only is the spectral color important for the active development of plants, but also the intensity and duration of illumination. In the gloomy days, it is not recommended to switch off the lamps for lighting the seedlings altogether.

But too much effort is not necessary, strengthening the daylight is also a lamp. On a fairly bright day, a seedling lamp is used as a kind of tester: it must be turned on to determine the need for illumination. If the illumination is significantly improved at switching on, the lightening should be continued. And if the light in the greenhouse did not increase and the difference before and after the lamp was turned on went unnoticed - there is no need to highlight it, it will only result in energy costs.

Distance between sprout and light source

Here everything is simple: the more power the lamp has for the seedling of seedlings, the farther it must be from the plants.

You can measure the distance using a ruler, of course. But it is not necessary. There is another way that allows the gardener, figuratively speaking, to visit the place of the plant.

You just need to put your hand under the light in the place where it is planned to put a pot with a sprout. If there is a sense of heat - the lamp needs to be removed or raised. With a close location of the light source, the plant will feel uncomfortable.

If the phytolamp seems too expensive

Or it does not even seem like it, but it's true: special lamps intended for dyeing sprouts are really expensive, and not every average gardener can afford this luxury - to look after young seedlings by all the rules.

Sometimes, obeying the instability of financial condition, the rules have to be violated and in search of an answer to the question: "What kind of lamps for seedlings can I use instead of special ones?" - find a number of alternative options.

One of them is the use of the most common, non-phyto-, wide-spectrum LEDs. For plants, they are optimal, because they have the necessary red and blue areas for vegetation, and for humans - too, since they are available in the price aspect.

Making a budget lamp for flowers and seedlings

There is no such gardener who does not like to bother with various adaptations to improve the vegetative functions of his beloved vegetation.

Arrangement of the artificial sun is one of the most important conditions for growth. Therefore, true lovers of the garden and vegetable garden give this issue a maximum of time and attention.

The most primitive seedling lamp for your own hands is created within five minutes. You just need to screw the LED light bulb into a regular cartridge. But this method is for the lazy ones. And the one who was born "a gardener" can not be lazy, so he is working on creating a lighting system a little longer and more seriously - for two hours.

For work you will need:

• 4 angles of 20x20;
• Flexible LED strip with 120 pcs. Lamps with a power of 20 volts / m.

The assembly scheme will only require you to glue the tape with the fixtures to the corners. The budget is about 700 rubles.

Plants will be grateful

In principle, under ordinary light-emitting diodes, all vegetation feels fine: it develops quickly and actively, the notorious first two sheets are thrown out in time.

White LED lamps are excellent in promoting the growth of seedlings of flowers and peppers, since they have a sufficient percentage of blue spectral color. And for tomatoes it is better to choose lamps with red lighting. In a certain phase of development, blue alone is not enough for them.

LEDs are an excellent way for those who contain greenhouses. In the autumn-winter malosolnechny period, thanks to the crumb-bulb, you can collect a pretty decent crop of vegetables and please yourself with the riot of spring flowers.

In additional lighting, plants from the winter garden are also in need. Despite the fact that they are usually placed on verandas and in the most light rooms.
