Make additional lighting for seedlings at home is not so difficult. But with what lamps will build backlight? This is a question that requires additional reflection. Let's figure out how to make the backlight with your own hands, and what, actually, to highlight. Additional information - in video and numerous photos.

Optimal selection of lighting

In the February cloudy days, when a thin, weak skeleton of a small seedling, we simply obliged to help him. It is necessary to install an additional "sun". That is, to arrange the lighting devices over the seedlings, so that the light day for the "kids" has increased, and they have more actively risen.

Additional coverage for seedlings can be organized using a daylight lamp

So, what can we offer young seedlings?

1. Incandescent lamps. This is not the best option, because they warm more than shine. Such lighting will be dried by green parts of plants, and even electricity consumed a lot. The only plus is inexpensive lamp itself.
2. Daylight lamps. The thermal radiation of fluorescent lamps is low, it means they can be placed directly above the plants. Lamps are economical and have a long service life. The only minus is low, so for high-quality backlight it will be necessary to use 2-3 lamps at the same time.
3. Mercury and luminescent lamps. Have good light characteristics, work around 5 years. But if they accidentally break, then the mercury pairs contained there will damage not only greens, but also to people. Such lamps need to be recycled after use.
4. Phytolamby. These are the same daylight lamps, only they emit color in a certain light range. It is believed that the plant is actively developing if the light falling on it consists of blue-violet and red-pink rays. Phytolampa gives just such a spectrum, but it is harmful to people, so it needs to be chosen by special reflectors.
5. LED lamps and ribbons. Rapidly gain popularity in vegetables. Their features are a red lighting spectrum, long-term use, low heating temperature and efficiency.

Additional Cardboard Box Lighting

While you choose the best option, it will be useful to get acquainted with the easiest and most economical way to illuminate seedlings.

Tip: Before the "burning garden", find out whether your shoots are really needed. Direct the lighting device at half a drawer with a seedler. If there is no difference between the illuminated and unlit part, then there are enough light. If the difference is essential, then the plants really need an additional lighting system.

1. First you need to measure the size of the container with the seedle.
2. Choose a cardboard box so that it has a little more than your shooter for shoots.
3. Cut off the top and side sides of the box so that there are 1 cm lights left.
4. Film the bottom and side parts of the foil. Fasten it for flights to the stapler, so that the foil is above the side.
5. Put a box with a seedl of a box on the window sill, closer to the light.
6. As a result, seedlings will receive an additional light reflected from the foil.

The method is good, but if you grow a lot of seedlings, then you can not do without lamps.

How many "suites" need a seedlings?

Optimal for the development of tomato shoots, pepper and eggplant is considered illumination from 6 to 8 lux. And more frequently, exotic plants are asked from 10 to 12 lux. For comparison: at the end of February, when the sun pleases us with a light to a maximum of 8 hours a day, lighting in sunny weather - 2 thousand suite. And on cloudy days - 500 suits.

In order to maximize the needs of seedlings, the light day should be about 15 hours with bright lighting. This means that the lamps should not be lit in the morning and in the evening, but throughout the day.

How to arrange the backlight

So that the seedlings rose normally and are not burned, the backlight must be positioned in a special way:

1. The optimal location of the lighting devices is at least 10 cm. From the tops of the plants. When seedlings grow up, the lamps will need to move. 2 options for designs with the ability to change the distance from the plants we will consider below.
2. For any illumination as an additional option, it is better to use the usual foil. It is better to set any surface on which the containers are located with a seedler. The rays of lighting devices, in this case, will be reflected, and highlights the seedlings and below.
3. For any kind of additional lighting, you need to choose reflectors. They will increase the efficiency of the backlight and protect people from constant bright light.

Lighting options at home

What the lamp you did not choose, you need to think about how to install it. You can make the backlight on the windowsill, on the table, on the personally built rack. Some put seedlings on open cabinet shelves, and the lamp is fixed over them.

Tip: If your seedlings are far from the window, the lighting system should work around the clock!

Let's look at the option of creating a special holder for phyto or luminescent lamps. It can be put on a table or any other smooth surface.

You will need:

• wooden bars with dimensions 2 by 4 cm, 1 m long;
• 12 short bars;
• two lamps;
• wire with switch;
• 2 screws 6 cm., And 2 to 4 cm.

Stages of work:

1. The lamp is fixed on a 1 m long board.
2. On both sides to this chalkboard from the sides are the legs. This uses 6 bars.
3. Similarly, you need to install the second lamp. This time, the configuration of the legs is a bit different, for greater stability, and to be able to change the height of the structure.
4. Two struts with lamps need to put a cross-cross, one over the other. For them to place seedlings.

You can make such a thing in 3-4 hours. Plus this mechanism in durability, in which it is possible to change its height, as well as it is easy to transfer if necessary.

You will need:

• boards;
• metal corners;
• means for processing a tree;
• bolts or screws.

Stages of work:

1. Determine the required length and width of the rack. Conveniently, if it is three compartments.
2. Construct open shelves.
3. Each compartment will be covered with a lamp attached at the bottom of the upper compartment.

The convenience of such a shelving is obvious. Shelves for seedlings are located on each other, which saves a place. You can deliver such a shelf anywhere, not necessarily near the window. Lack of design - it will not be possible to change the distance from the lamp to the plant.

Hang the lighting device with your own hands

Attention! How to understand, at what distance is it better to hang the lighting device? Mark your hand under the light bulb surface. If they felt warm, the light source must be moved.

Let's deal with how to hang any purchased lamp if it does not have its own fastening system. You will need:

• 2 hooks with thread;
• 2 chains;
• luminescent, LED or phytolampa.

Stages of work:

1. The special holes in the lamp need to insert two dowels.
2. They screw the hooks with carvings.
3. On the rings hinder two chains.
4. Now we can apply this suspension design on any shelves, bedside tables and windows. It is enough just to hang the chains on some ledge. Adjusting the length of the chain can be raised to the lamp higher as shoots row.

Regardless of your chosen type and method of backlight, your seedlings will receive the maximum amount of light. It means that they will be perfectly developing even in the cold and cloudy months. So, you can please early harvest.

Preface

The backlight for seedling plays the same important role as regular watering and making feeding. We will tell about what lighting devices to use to not harm seedlings, and to maximize its quality.

The optimal period of seedlings is 12 hours a day. To achieve such indicators in February or March is extremely difficult due to a short luminous day, cloudy weather. Therefore, without the help of the backlight it is not necessary. It will help to extend the light day, which is especially important at the initial stages of growth, evenly distribute the flow of light and will not give seedlings to stretch, and will also provide a plant with a necessary color spectrum for vegetation. The main goal when choosing a lighting device - as much as possible to natural lighting. The plant, like a person, needs rest, so the night lighting devices must be turned off.

Backlight for seedlings

The light has spectral division into 12 segments, which in turn are divided into primary, secondary and tertiary colors and shades. Each of these colors affects the plant in different ways. The most important color spectra are red and blue. The Red Light contributes to the active germination of seeds, the development of shoots and synthesis of chlorophyll, and its disadvantage causes dullness and deformation of young seedlings.

Blue light contributes to the braking of the growth of the stem, especially the heating part, preventing that for many gardeners is a big problem. Due to the effects of blue light, cell division occurs, which is why the stem thickens and becomes stronger. Orange, yellow and green colors absolutely do not affect the development of the plant. Conventional incandescent lamps are not suitable for seedlings. They emit only a red-yellow spectrum and heated too quickly, it can lead to burns of plant leaves and diseases.

Despite the large variety of modern lamps for seedlings, fluorescent lamps and tubes are not losing popularity. They have enough warm radiation, they do not overheat, which makes it possible to hang them at a short distance from the plant. The elongated tubes are conveniently placed in the window opening on hooks and adjustable chains. The productivity of such lamps is high. They are capable of working up to 10,000 hours, without reducing the intensity of the light flux.

Fluorescent lamps for seedlings

The color temperature of fluorescent lamps may differ, and its indicator is always indicated on the package and is denoted by the unit of measurement to (Kelvin). The lower the indicator, the softer the light of the lamp. The yellow shade of the lamp is ranging from 2700 to 3000 K, the cooler tons with a blue tide - 5000-6000 K. For seedlings, it is preferable to use the lamps of daylight, the color temperature of which is in the range of 4000-4500 K.

Among the finished options for highlighting, we recommend the lamp 3 yields of OFZ Based on three luminescent lamps. In addition to lamps, the package includes racks and a panel where lamps are suspended and inserted. The lifting height is adjustable using built-in fasteners, which is very convenient. According to manufacturers, such lamps create illumination at 10,000-15,000 lux, thanks to which you can get a strong and healthy seedlings even in the absence of the sun outside the window.

Today, LED lamps (LED) are actively used in everyday life and production. Many recognize LEDs with the best solution and for growing seedlings on the windowsill. They combine two important spectrum for the plant - red and blue, as a result of their connection, a soft purple shade is obtained. Such a light may be unpleasant for us, however, the plant reacts well to it. LED lamps highlight visible light and minor heat, which allows them to be placed at a minimum distance from the plant without harming it.

LEDs and phytolampa bicolor

The price range of such lamps is varied, it all depends on the quality of the assembly and the power of the LEDs. However, even expensive backlights quickly pay off not only because of the high release of light up to 6000 suites, but also due to energy saving. In addition, such lamps are easy to assemble and operate, they practically do not require any additional devices.

Phytolamba, created on the basis of LEDs, are intended for growing any cultures both at home and in a greenhouse. How not to make a mistake with the choice of phytolamba? First of all, pay attention to the luminaire case or the so-called radiator. It should be made of aluminum or other reliable metal alloy. Such an outer shell testifies to the high power of the lamp and the quality of the luminaire itself. But it is not recommended to choose phytolambamps in a plastic frame with small slots. In such lamps, heat will be collected inside the protective cap, and as a result, the lighting device can overcome and completely fail.

For home use, we recommend purchasing LED lamps Bicolor With the E27 base, which can be inserted into any standard cartridge. Thanks to the protective lens, the lamps have a directed range of action, distributing the light beam strictly to the reserved angle. The number of LEDs may be different. The most popular option is phytolampa Bicolor With 12 LEDs, the power of each light bulb is 3 W. Nine light bulbs of this phytolamba are presented in a red spectrum with a wavelength of 660 nm and three light bulbs in the blue spectrum - 450 nm.

The rated power of such a lamp is 36 W, in practice it consumes only 15-18 W, depending on the lighting intensity.

For convenience of fastening the lamp, we recommend using a cartridge with a clothespin at the end, which allows you to fix the lamp on the bracket or on the shelving shelf. When placing a lamp in the cartridge, it is desirable that it be without a lampsier. So all heat in the radiator will go into an external environment, and not to be assembled inside, which is extremely important in order to avoid overheating. By 1.5 m of the windowsill, we advise you to install two lamps. Bicolor.

Often, lovers ask a question how to make backlight for seedlings? Of course, powerful lamps or complex structures are better to purchase in a specialized store, and for a small window greenhouses you can make your mini-lamp.

Purchase rack for seedling

An alternative to massive lamps will be the tape backlight for seedlings made by their own hands. For its assembly, you will need:

• lED bulbs with red and blue spectrum;
• thermal panel or thermoclay;
• a piece of aluminum, profiles from furniture or any other reducing material for the base;
• power supply or driver;
• cord and fork.

LED bulbs are fastened on the base, pre-applying thermal and thermocons, connect them between themselves using soldering and display a power switch with a switch and fork. The resulting tape can be consolidated by any way convenient for you - bolts, double tape or strong rivets. The system assembled into a single chain can be used. For a powerful light flux, you can make multiple LED tapes.

It is easy to grow seedlings on the windowsill, but sometimes there is not enough space to comfortably place all the plants. In this case, it is advisable to construct special racks or install individual shelves. With the help of such structures, you will be able to save space and arrange the entire seedlings in one place.

As the basis for the shelving, any stable materials, ranging from a metal corner and ending with wooden bars from old furniture. The final design will have a P-shaped form. We connect the frame and shelves using self-tapping screws or bolts. When using wooden bars, we first advise you to first make small holes for bolts with a drill with a diameter of 1 mm, and then slightly expand them with a larger drill of 7-8 mm. This will help avoid tree cracking.. The length and width of the rack will depend on the size of your window opening. Do no more than 3 tiers in height.

Rack for seedlings at home

A backlight for seedlings is installed on each tier, which should not overlap natural lighting on the windowsill. Consider that as the plant increases, the lighting intensity will change, so during the installation of the lamps, chains with fasteners should be provided for a height change. At the initial stage of growth, the illumination should be located at a distance of at least 10 cm, and after the formation of the seedlings - 25-35 cm. The adjustment of light will make it possible to form a strong plant, increase the green mass with a saturated color and prevent pulling out seedlings. And if it seems to you that the light is not enough, we advise you to put a reflective foil.

When choosing a suitable highlighting lamp, give preference to fluorescent or LED linear lamps (LED). Pay attention to the power of the light bulbs, as well as the luminaire case, which must be made of aluminum. Such lamps have insulated LEDs and are not afraid of wet air.

Improve the lighting on the windowsill will also help reflectors that are installed behind the plant. Absolutely any materials can be used as a reflector, capable of passing through themselves and reflect it into an external environment. The simplest and budget option will be the usual Watman or white paper sheets. Strengthen reflection capable and foil paper. Such methods are effective and occupy a minimum of space. Remember, reflectors are able to increase the area of \u200b\u200bdispersion, but not the intensity of the light stream, it is especially felt on cloudy days or when growing seedlings on the north side. That is why such materials must be applied together with phytolampa.

Reading: 4 minutes

No seedlings planted even in the highest-quality primer will not grow if it does not have enough enough light.

To sprouts to grow to spring, they have to plant them in winterWhen the amount of daylight is not enough. It is in this case that they appeal for help.

Is LED illumination possible?

Illumination with the help of LED tape today is not only possible, but also necessary in many cases. It can be purchased in the store, and also make it yourself.

People who care about their future crop will necessarily have a similar system, because it really improves the growth and development processes of normal seedlings.

LEDs provide for the development of sprouts lighting

A certain color spectrum, scattering lighting of LED lamps during the cold season replace sunlight or fill its shortage. That is why the installation of their winter is simply necessary.

What spectrum is better for highlighting?

The luminous spectrum affects seedlings in different ways. This type of lamps creates the necessary range of colors:

1. Blue- promotes the development of the root system.
2. Red- stimulates the growth of the entire plant, as well as the process of its flowering.
3. Pinkhelps to develop leaves and improves the flowering process.

The advantages of such a highlighting

It is considered the most appropriate because it has a number of positive properties:

• The length of their waves is much larger than that of conventional incandescent bulbs. This creates favorable conditions for photosynthesis;
• Produce the light of the necessary brightness, which is their feature;
• Such lamps consume energy much less than ordinary, which allows to save a significant amount of cash;
• Characterized by a small supply voltage, which allows you to install them close to the water source. No threat to others in this case, they do not carry;
• Do not overcame plants because they practically do not heat them;
• Do not possess a stroboscopic effect;
• Ultraviolet, as well as infrared radiation, these lamps do not form, thus creating safe conditions for the development of some seedlings;
• Produced from environmentally friendly materials;
• Are completely fireproof;
• Have a long shelf life (on average, this figure is 50 thousand hours), the light bulbs almost never burn out.

LED-ribbon looks like

A large list of benefits explains the high popularity of this type of highlighting.

The analyzed tape is very easy to use. However, to obtain the best effect and uniform growth of all seedlings, you need to get acquainted with such recommendations:

1. Place tapes necessarily in two rows.
2. It should be borne in mind that all LEDs have a specific lighting cone.
3. To stimulate the root system, as well as growth in width, and not height, a combination of blue and red colors are used. In this case, the number of first must be twice as bigger than the second. This method is best suited for the dive process.
4. The backlight must be installed in such a way that one of the selected colors or a combination can be operated at any time.
5. To safely use such lamps, you need to connect the power supply that can change the voltage in the network up to 12 or 24 V. Only such an indicator is permissible for LED tape. In addition, such a bar transforms alternating current to a permanent.

Reference. It is better to acquire a device equipped with a current stabilizer, which will save the entire design from voltage drops.

6. In order for such a type of lighting a result, you need to follow how seedlings behave. With their poor development, the lamp must be turned off or changing its color.
7. The duration of the daylight for each type of plants should be selected individually, which also need to be remembered when choosing a similar method.

Make a lamp do it yourself

Homemade lighting device

Make them yourself will not be much difficulty even without any special experience. The main thing is to follow a clear instruction:

1. Clean the ends of the wires and treat them with a special fluid.
2. Secure on wires of matrices, which must first be connected by plus and minus.
3. Place the wires on the LEDs connected to the power supply.
4. Secure LEDs on the plate using glue.

Note. To do this, apply a glue on an epoxy basis.

5. To place the lamps, you need to select the reflective side of aluminum.

How to fix the LED lamp on the panel?

In the event that the installation will be made independently, you need to take care that in the process of care of the seedlings, the tape did not interfere with doing this.

Attention! Connect the tape under consideration directly to the network in which there is 220V cannot.

Fasten the ribbon best on the aluminum panel. The process of its installation is as follows:

• Clean the surface of the panel from dirt and dust, degrease it;
• If necessary, cut into a ribbon of a certain length between the attack;
• From one edge of the tape to remove the protective layer. There is a glue under it, with the help of which will be installed. If there is no pre-applied layer of glue, epoxy and rivets are used for fixing;
• Applying small efforts, fasten the material on the panel, slightly pressing it to the base;

Important! Do not allow ribbons, it may damage it.

• Consolidate the panel in the right place and place saplings under it;
• Observing polarity, connect the ribbon. Otherwise, the diodes will not burn.

Useful video

See the informative video about the independent assembly of the diode tape below:

The highlighting of seedlings with the help of LED ribbon will necessarily give the result. If you wish, it can be easily made or buy in the store. The main thing is not to be afraid to spend money on it, because in the future it will affect your crop.

Competently organized lighting with compliance with the required intensity indicators is one of the most important collaterals for getting a healthy and strong seedlings. In some cases, it turns out to be sufficiently simple daylight, but most situations have to organize additional artificial illumination using lamps. Today manufacturers offer a fairly wide range of similar devices.

For the most part, floral and vegetable crops are thermal-loving plants, growth efficiency and the features of the development of which are largely determined by the duration of the daylight. Light shortage leads to a slowdown in the flow of photosynthesis processes and the emergence of various diseases in seedlings. To avoid listed and associated problems, additional lighting is organized.

Sunlight consists of several waves of different lengths and colors. In order for photosynthesis of plants in accordance with the established norms, it is necessary to organize their backlight with a full-speed light. Along with this, each spectrum performs its important functions.

About them in the table.

Table. The role of light spectra in the development of seedlings

Basic lighting requirements

The key characteristics of the lighting are its duration and level of intensity. The intensity is determined by the power of the lighting device used and the distance between it and the plants. The optimal distance is determined like this: you turn on the lamp and substitute your hand under the light. If it feels warm, the lighting device must be removed slightly.

Normal light level for plants is considered an indicator of 8,000 suite. With the task of providing its provision presented under today's publishing lamps for home seedlings will greatly cope, but additional highlighting will have to be included not only in the morning and in the evening, but also during the day, especially if on the street cloudy weather.

To verify the need to use the lamp, simply turn it on. Noticed a significant change in the level of illumination? In the use of additional backlight there is a need. Do not see a special difference? Illumination can not be used.

Assortment of lamps for seedlings and their main features

A lot of varieties of lighting devices are available on sale, which can be used when growing homemade seedlings. Consider the most popular of them.

Sodium lamps

Among domestic gardeners, the lamps of production of reflax are most popular.

The key positive qualities of sodium lamps include the following points:

• high highlighting performance;
• ensuring a stable stream of light;
• impressive service life;
• creation in general favorable conditions for the normal flow of photosynthesis processes.

The main disadvantage is relatively high cost.

The table provides information about the main representatives of the range.

Table. Popular sodium lamp models

Fluorescent lamps

Cold lighting is emitted, similar to the natural daytime. Characterized by weak power, which forces them to install them in an increased quantity. In addition, to the number of flaws of fluorescent lamps, the small content of red light in the spectrum should be attributed.

Having calculated the required amount of lamps, we use the following dependence: each 1 m length of the window sill with seedlings is served by the lamp with the 80-watt or two 40-65-watt lamps.

Important! Do not use the luminescent lamps of the LDC and LDs - plants to illuminate the fluorescent lamps react poorly to the light emitted by such devices.

Phytolampa

Fitolampa multiple marks use the greatest popularity among gardeners.

1. Fluora from OSRAM. Fixtures with a capacity of 18 W fit. To make a 1 m windowsill, have enough one or two such lamps.

   

2. LFU-30. Characterized with a capacity of 30 W. One lamp is enough to maintain a platform 40x70 cm.

   

3. Enrich. Comparatively weakly irritate the eyes, but are characterized by small (on average up to 6 months) service life. In addition, such lamps are very highly heated by the leaves of seedlings, which is not the best reflected in its condition.

   

4. Paulmann. May have different power. From the nearest analogues are distinguished by almost zero heating, which eliminates the risk of overheating seedlings, as well as an impressive service life.

   

5. Phytosvet-d. Category LED appliances. Suitable for both use at home and for use in greenhouses.

   

The key advantages of all phytolamp are as follows:

• high efficiency;
• compactness;
• the impressive indicators of environmental friendliness, efficiency, durability and security in general.

The disadvantage is reduced to the lilac-pink color of the glow, which is not the best way reflected in the state of the human eye and his health. In residential premises such lamps are allowed to use solely in a complex with an outer mirror reflector.

Is it possible to use ordinary light bulbs?

As it becomes clear from the above information, for seedlings you can use lamps of many variety of types, but each of the options has its weaknesses.

The question arises: is it necessary to buy additional lighting devices? Is it impossible to do with ordinary household incandescent bulbs?

It is impossible. Such lighting will be ineffective and simply useless. According to averaged data, incandescent lamps with traditional tungsten thread transform no more than 5 percent of energy. Everything else is simply warm. In addition, the spectrum of light of such lamps is not suitable for plants: they will rehabilitate, to burn, stretch out and in general is not necessary to form as it should.

Now you know which lamps can be used with seedlings with independent cultivation. Harvesting you!

Video - What lamps are needed for seedlings

Since the seedling plant is often produced at the end of winter, when the duration of the daylight is still not enough to ensure a full photosynthesis, the question arises about the additional backlight of the home greenhouse.

In the range of specialized stores for the garden and the garden there are so-called phytolambuses - LED complexes for highlighting seedlings in greenhouses. From other sources of artificial light (the same incandescent lamps), they differ in greater disposal efficiency due to the fact that the rays of different spectrals are equally missed:

• blue;
• red;
• purple.

Photosynthesis (the process that causes the growth and development of plants) and the photomorphogenesis (the process of rising fruits) reaches a peak when exposed to light rays with a length of about 660 nm. This indicator is provided by a combination of red and blue light waves in a 3/1 ratio. Most phytolamps offered in the market are characterized by this ratio of light waves.

Another advantage of the LED lamps is their economy - the power consumption of such sources is several times lower than that of conventional incandescent lamps. In addition, LEDs burn out much less often.

The main minus of such sources of additional light is their price. High-quality phytolambuses are not suiced, with small volumes of the planting of home greenhouses, the harvest with such expenses may not pay off. But if you make the LED backlight itself, savings compared with the purchase of finished phytolamp will be significant.

Is it possible to assemble phytolamps yourself?

On the horticultural forums can be stumbled upon the themes describing the creation of phytolamps with their own hands using LED tapes or individual LEDs recorded on a metal profile. But to gather such a backlight for seedlings, it is necessary to understand well in electrical engineering. The main complexity is to assemble the source of the current from the resistor and the stabilizer (instead you can buy a special driver, but then the cost of the design will be significantly higher). It is easier to collect phytolampa with your own hands on a simplified scheme from ready-made LED Laps, which can be bought at any lighting shop.

Materials and tools for assembly:

• lED lamps of red and blue on 3 LEDs;
• fragment of the chipboard of a rectangular shape;
• cartridges for LED lamps (the amount must correspond to the number of lamps);
• drill;
• screwdriver;
• soldering iron;
• fasteners;
• cord with a fork.

Stages assembly construction

The assembly of the system of artificial illumination of plants by LEDs according to this scheme does not provide anything complicated. We consistently perform the following actions:

1. On a LISP Sheet Pencil Place the Installation Places of Future Lamps and with Drills Drill a hole in the center of each of them for further posting.
   
   
2. Using a screwdriver, fix cartridges for lamps in marked places.
   
   
3. We screw the lamps into the cartridges, after removing the diffusers from them and we convene all the electrical wiring elements in series using soldering.
   
   
4. Complete the assembly of the electrical circuit with a cord with a fork. Now you can spend a test start of the design. Well, if for these purposes there is a laboratory power supply with the ability to submit voltage less than 220V.
   
   
5. After making sure the lighting system works, you can connect it to the main network and mount directly above the seedler.

Backlight for seedlings based on LED matrices

The above describes the process of assembling the seedlings of seedlings from individual LEDs. Such systems are effective for individual boxes with seedlings a la "Babushkin Balcony". For lighting seedlings in large volumes (mini-greenhouse), it is better to use homemade backlight systems based on LED matrices. The cost of building such a device will be higher than in the first case, but still incommensurate with expenses for the purchase of ready-made phytolamps for mini-greenhouses. The basis of such a system - LED matrices for plants with a double spectrum.

You will need the following components:

• lED matrices - 4 pcs;
• old processor radiator;
• connectors for LED matrices;
• drill;
• termoklay;
• fasteners (screws);
• computer fan for 12V;
• screwdriver.

Step-by-step assembly instructions:

1. Using drills, we plan 8 holes on the housing 8 holes for fixing LED matrices.
   
   
2. We install on the drill drill under the thread with the M2 diameter and we drill the outlined places. The depth of the holes must correspond to the size of the screws.
3. With screws and thermoclauses, we perform the fastening of matrices to the radiator housing in the planned locations. First we apply a small amount of glue on the base of the matrix and gently apply it to the place of the mount, then screw the screws.
   
   
4. Now we can consistently connect all the LED mitrix with connectors and set the connector to which the current source will be mounted (LED driver).
   
   
5. We connect the driver to the connector and check our design to work.
   
   
6. The final stage of the assembly of phytolamba on LED matrices is connected to a 12V fan electrical network. Without it, our radiator will quickly overheat.

Checking the effectiveness of the draft system

Whatever the backlight system of seedlings you have not chosen - factory or homemade, the principles of checking its effectiveness are the same. The main evaluation criterion is the appearance of the seedlings:

1. If in some parts of the greenhouse, the stems of stem, unequal length, which means plants lack light. The solution to the problem can be the additional lighting of the site (try moving the profile with fixed LEDs closer to seedlings).
2. Straight, as on the selection of stalks with bright green leaves, indicate that plants are completely enough light. Reduce or increase the lighting intensity in this case should not be.
3. If the sheets become sluggish, cough, most likely the backlight system will strongly "fries." Try to reduce the number of LED panels. To determine if there is no overheating, hurt your hand over the tops of seedlings. If you feel that it takes out, then you have moved heated.
4. Remember that for each culture there is its own light mode. Determine when you need to turn off the backlight, the plants themselves will help. Take a look at their sheets: if they start closing (stretch vertically) - it means it is time to stew light. To freely check boxes with the seedle, not only in the dark, but also on cloudy days.
