Most gardeners from the end of winter begin preparing for the new season. They sow seeds at home to get good planting material. In the cold season the vegetation lacks sunlight. Houseplants also suffer from its deficiency. To help them, apply artificial lights. To do this, install a lamp for seedlings.
The need for additional light
Almost all flower and vegetable crops are heat-loving species. Their activity of growth and development will largely depend on the duration of the light day. With a deficit of sunlight, all photosynthesis processes are slowed down, which leads to plant disease.
To avoid such problems, it is necessary to organize additional lighting for indoor plants, including seedlings. Key requirements for backlighting are:
- level of intensity.
The last indicator is determined by the power of the device used. The distance from the luminaire to the seedlings is also important. With an insufficient amount of light, the root and aboveground parts of plants suffer. If they are deficient, they begin to be pulled upwards, which is why their immunity suffers. The seedling becomes painful and in the future it will not be able to fully develop and give a good harvest.
Features lighting seedlings
Solar natural light, the most familiar to all living things on the planet, combines light waves of different lengths. Part of the spectrum is visible to the human eye, part is not, but all this diversity is important for plants, and waves of different lengths play different roles in different segments of the seedlings life.
- The blue and red part of the spectrum helps the active production of chlorophyll, and the plant, receiving such light, develops faster, which is important for seedlings.
- The orange part of the spectrum is also necessary for growth in the conditions of the room, and also contributes to fruiting.
- Green, like yellow light, is reflected from the foliage and cannot strongly influence its growth, but, as part of natural light, it is also necessary.
- Ultraviolet radiation, which is included in the invisible part of the spectrum, helps to fight against pathogenic bacteria, fungi and other plant diseases, however, in large quantities, ultraviolet light can do more harm than good.
- Infrared radiation is well perceived by seedlings, helps its growth and the formation of lush greenery, but gives no longer light, but heat, and therefore does not always benefit.
Which seedling lamps are better?
Artificial lighting provided by lamps cannot copy the sunlight exactly, but it is fully capable of providing adequate conditions for the rapid growth of any kind of seedlings.
Moreover, thanks to the lamps for the backlighting of seedlings, it became possible to make the vegetation of many plants year-round, to obtain several harvests and to grow plants where previously it was simply impossible, for example, in the polar night or in rooms without windows.
However, this effect can give far from all sources of artificial light.
For example, the most common incandescent lamps are unsuitable for the reason that only 5% of the energy consumed in these lamps becomes light, the rest is converted into heat. Plants under such a lamp are not illuminated, but heated, which leads to thinned sprout sprouts that are at risk of getting burns.
Specialized bulbs for illuminating seedlings should provide their wards with a certain emission spectrum, allowing plants to quickly get up to speed and, in not very comfortable conditions, reach sizes sufficient for planting into the ground. In addition, these light sources are more economical and produce less heat.
Sodium lamp for seedling lighting
There are several types of such lamps. The most popular ones are those produced in the Russian company Reflaks.
These gas-discharge lamps give a warm orange light that does not irritate human eyes, so they can be used not only in greenhouses, but also in residential areas. In addition to Reflax, there are other reliable manufacturers, for example, General Electric, no less well-known OSRAM or Philips. The main consumer of these agrolamps for seedlings is large and small greenhouses. But for home conditions there are samples with a capacity of up to 100 watts.
Reflaks of the DNaZ brand are equipped with a factory mirror reflector and can be considered the best option among analogues. The reflector enhances the luminous flux and directs all the light to the plants. And for high-quality illumination, a gas-discharge light source with a power of 70 watts is enough for a half meter sill.
Sodium agrolamps for seedlings DNaT do not have a mirror reflector, so the lamps of 70 W will have to place one for each meter.
And here sources of the DRiZ brand are better for combining with lamps of DNAZ and DnT. This will give the opportunity to get the most natural range of lighting.
The advantages of domestic reflaks sodium lamps:
- The highest efficiency of the backlight system,
- Long service life
- High price of light sources
- The large size of the lamps themselves,
- The lack of waves in the blue part of the spectrum,
- The need to equip the system with a regulating device.
Today you can find quite a few varieties of special fluorescent lamps to illuminate seedlings:
- The most famous are phytolamps “Fluora”, produced by Osram. To illuminate a shelf with a seedling per meter, one or two 18-watt lamps are sufficient.
- Russian fitolamps with LFU-30 markings have a power of 30 W and can be used one per meter of sill.
- Enrich phytolamps with a mirror reflector and 60 W power almost do not irritate the eyes, but emit a lot of heat and are short-lived.
- Phytolamps for additional lighting of Paulmann seedlings of different, from 40 to 100 W, power almost do not heat up and have a long service life.
- Small size
The disadvantage of the Flora lamp for seedlings from Osram and other representatives of similar light sources is that they all have lilac-pink radiation unnatural for the human eye. Therefore, they are best used only in the presence of a screen or reflector separating the room from the location of the seedlings.
White white fluorescent lamps can also be used for lighting, however:
- They are not too powerful
- In the light there are not enough waves in the red part of the spectrum.
To get a sufficient flow of light, the distance from the luminaire to the tray with seedlings should be from 15 to 35 cm, and two lamps with a minimum capacity of 40 watts will have to be placed on the meter sill.
LED lamps for growing seedlings
For plants, this option is probably one of the best. Using a combination of LEDs that give white, red or blue light, you can get the backlight of maximum efficiency.
At the same time, LED lamps for growing seedlings have high efficiency, are durable, and the spectrum of the entire system can be simply adjusted, given that the needs of seedlings change significantly as they grow.
- Before picking seedlings, the light emitted by blue and red LEDs, set at a ratio of two to one, is better perceived. Abundant blue here activates the growth of the root system, but slightly slows down the stretching of the ground part. The stem is strong with frequent internodes.
- After picking, it is better to reduce the light intensity for several days in order to ensure a rest mode after a stressful transplant. Next, it is necessary to illuminate the seedlings with LED lamps of blue and red in the ratio of 1 to 1.
The only disadvantage of LED-lamps is the high cost of ready-made systems, which, when growing seedlings for personal use, will not pay off in less than a couple of seasons.
Asking what kind of lamp for seedlings is better, you can consider the option that has appeared quite recently - these are induction lamps.
Bispectral light sources can be considered as the most perfect, producing radiation in two parts of the spectrum that are most in demand by plants.
- High efficiency and cost effectiveness
- Universal Spectrum
- The temperature of the lamp does not exceed 75 degrees.
Unfortunately, none of the sources of artificial lighting can completely replace the sun, however, phytolamps for additional lighting of seedlings actually shorten the period of plant growth for planting in the ground. Their quality improves, and the proportion of rejected shoots decreases sharply.
Placing lamps for plants
To improve the efficiency of illumination, it is important to take into account the characteristics of the placement of lamps:
- The higher the temperature of the working lamp, the higher it should be placed above the trays.
- At different stages of growth, plants need different light levels. For example, after sowing trays should be illuminated around the clock, in some cases, changing the color of the LEDs.
- For the greatest effect, you should combine lamps with different characteristics.
To save electricity will reflect the reflectors, reflectors and light screens that can be made independently.
Basic lighting requirements for plants
Many early varieties of plants begin to grow on seedlings in February. For the normal development of seedlings need uniform coverage for ten hours. But to provide such conditions with the help of sunlight at this time is simply impossible. Therefore, experienced gardeners use special lamps.
Select such devices should be relatively basic requirements for seedlings:
- the plant should receive only soft lighting
- during operation, the lamps should not become too hot, raising the air temperature,
- the light device must completely and uniformly illuminate the seedlings,
- the lamp must be at least ten centimeters from the seedlings,
Illumination is measured in lux, and is determined by the amount of light flux falling on one unit of area.
The best level of illumination for seedlings is 8000 Lk. This indicator is necessary light-loving plants. Shade-loving cultures grow better with a light index of 6000Lx.
When growing seedlings in greenhouses used a different number of lighting devices. In the early stages of the development of young cultures, the light is left for twenty hours. For older plants, the light index is reduced. Twelve hours a day is enough for their further development.
Which type to choose
Conventional incandescent bulbs do not give good results when growing seedlings. They quickly heat up and dry out the air. Young plants overheat and become weak. Therefore, special lamps are used for lighting.
Plant lighting sodium lamp
High-pressure sodium lamps are used to illuminate young cultures. Among other lighting devices, they are considered the brightest. The main advantages of the sodium electric light source are:
- ensuring stable light input,
- long rock service
- lighting efficiency when growing seedlings.
These lamps emit yellow-orange light that does not irritate the eyes. Due to this sodium lighting devices can be used at home.
Many lamps are made with special mirror reflectors. With this addition, you can evenly distribute light over a large area.
The disadvantage of such artificial light sources is the high price of the product. Also, the lamp can not be used at voltage surges in the mains.
Sodium lamp for seedling lighting
The effectiveness of fitolamp for seedlings due to the following indicators:
- high power - you can use only two photoluminescent lamps for full lighting of the greenhouse,
When purchasing such a lamp for lighting plants, you should pay attention to the presence of reflectors, the angle of light scattering, power and brightness.
Lamps of this type have a low cost and much better than conventional incandescent bulbs. They create bright lighting and do not get very hot. But the halogen lamps can illuminate the seedlings for a short time, since after a time the level of commitment from them is significantly reduced.
These lamps are mainly used as additional lighting when it is necessary to increase the level of red.
Types of lamps by color
Seedling lighting with LED lamps
For the full development of the plant requires the activity of the photosynthetic reaction. This process can only be achieved with high-quality lighting. Each culture has its own color preferences at different stages of growth. Therefore, lamps for lighting in the process of growing seedlings can vary according to the color spectra.
The importance of lighting
Everyone knows that to grow strong seedlings light is an important component. And in winter and in early spring, when new plants gain strength, the natural sunny day is rather short.
In this case, additional sources of light, such as lamps, come to the rescue. Completing the plants at home should be in accordance with the stage of development and the purpose of cultivation, because the choice must be made consciously.
Each color of the light spectrum has its own characteristic:
- red and blue - stimulate metabolic processes, increase the production of chlorophyll, accelerate photosynthesis,
- orange - speeds up fruiting, is used in winter greenhouses to accelerate the ripening of fruits,
- yellow and green are important colors during growth, they are easily reflected by seedlings,
- ultraviolet - has a bactericidal effect, inhibiting the growth of harmful organisms.
Did you know?For the first time ever lighting of plants with the help of lamps was applied in 1868. This was done by a scientist from Russia, Andrey Famintsin.
Despite the fact that each plant has its own specific requirements for the spectrum of illumination, with its lack of photosynthesis slows down, biomass grows slowly, and seedlings start to hurt. A suitable level of illumination is the limit of 8 thousand lux. Modern technologies, namely the illumination of plants at home, will help to bring seedlings as close as possible to the desired parameters and achieve illumination of 6 thousand lux.
Whether any, or types of lamps for lighting seedlings
Today the market is saturated with various lighting devices that help to get the right amount of light. However, many are interested in how to choose the right device for lighting seedlings and what features are popular models.
Important!Any selected type of lighting to save energy can be provided with light screens. To create them, it is enough to stick on the sides of the container with foil or plain white cardboard.
Some people think that in order for the plants to get the right amount of light and heat, it is enough to hang a few ordinary lamps over the seedlings. However, ordinary devices do not have the necessary color spectrum for full illumination of plants.
Consuming a sufficiently large amount of electricity, they convert only 5% of the light, and the rest is converted into heat. As a result, the plants receive not light, but additional heat and, as a result, overdrying or burns on the leaves are obtained. Therefore, the use of incandescent bulbs is not as effective as the others that are gaining popularity today.
Fluorescent Lamp - one of the best options for receiving an ultraviolet which is so necessary for plants. Due to this effect, intense growth of saturated color seedlings will occur. In whom this color leads to a decrease in the level of pathogenic microbes.
Additional advantages of use are the absence of high temperature at the lamp, which makes it possible to maintain the desired microclimate around the plants. Despite the positive moments, such lamps still have some drawbacks. These include the absence of the required number of waves in the red part of the spectrum.
Also, they do not have much power, and, therefore, a quick result with them cannot be obtained. To obtain the desired result, the distance from the luminaire to the seedlings should be in the range of 20-30 cm. The ideal power is 40 watts.
The use of lamps for additional lighting of plants will allow you to grow arugula, tomatoes, strawberries, green onions, lemon balm and mint at home.
Sodium lamps are considered the brightest in comparison with others. The spectrum of their radiation optimally helps plant growth. They are divided into two types: low and high pressure. The latter are used for supplementing the seedlings at home and accelerating the ripening of fruits.
Some members of this group have a mirror reflector, which allows you to cover a large area, which saves money. Отрицательными моментами использования является сильный нагрев и небезопасность применения, так как при производстве используют ртуть со смесью натрия.
Эти лампы нельзя включать, если присутствуют перепады напряжения больше 10 %. Понижение температуры окружающей среды приводит к снижению эффективности работы таких ламп. Lamp power should be no more than 100 watts.
Important!Lamps with sodium lamps is strictly prohibited to include in the simple outlet. For them, you need to use special equipment, chokes and pulse-incendiary devices.
LED lamps for seedlings are gaining popularity among summer residents and farmers. Using similar lighting on seedlings leads to the following results:
- reduction of electricity consumption,
- due to minimal heating, the lamp can be placed practically near the plants,
- In the lamp are diodes of different colors, which allow you to get red and blue colors at the same time,
- high operational safety minimizes potential losses,
- lack of drying and excessive thermal humidity,
- lack of minimum infrared radiation.
Lighting seedlings with LED lamps will accelerate photosynthesis in plants due to a different glow.
Phytolamps are complex devices, their price depends on the technical characteristics: power, brightness, dimensions, angle and area of illumination, heating of the case and service life. Deciding to purchase such a device and being in search of information on how to choose fitolampa for seedlings, it is important to consider all the above characteristics.
These light sources are considered to be convenient to use, quite economical and do not require additional cooling. Several fitolamps will completely replace all lighting in any greenhouse. The disadvantage of using a purple lamp is that this light can cause people a headache.
Did you know?The plant needs alternation of light and dark periods. So, you need to periodically turn on and off the lighting. The ratio should be chosen depending on the type of plant.
Excessive light is also undesirable, as is its disadvantage. As a result of glut The following situations may occur:
- leaves lose their natural color
- flowering occurs very quickly
- leaves may become covered with burn-like spots, and they frown and die.
To prevent this, follow the lighting. In case of need rearrange devices.
Knowing the basic parameters of the choice, questions regarding the proper selection of the lamp should not arise. Compliance with all the rules of the post-lighting will allow you to get good planting material and, as a result, a high yield.
Which is best to choose the type of lamp?
There are many advantages of pre-lighting devices, and it is rather difficult to overestimate their role in the process of seedling growth.
First, artificial insolation completely imitates the flow of sunlight, therefore it contributes to the gradual development of a young seedling in the same way as it does with natural light from the sun.
Secondly, due to good additional lighting, the plants will grow “correctly”, without deviations and interruptions. Many summer residents ask about whether it is possible not to use lamps for home seedlings? The experts' answers boil down to the conclusion that it is not desirable to leave developing plants without artificial lighting. If you neglect them, such seedlings can stretch, and the leaves will be pale and underdeveloped. In some cases, the deformation of the base of young plants can be observed. On the yield is greatly affected.
And thirdly, with very early growing of seedlings (petunia flowers, begonia, sabo cloves, lobelia, vegetables - late pepper varieties, celery, potatoes and black onion from seeds), prolongation of daylight by artificial insolation is very necessary.
What should I expect from a seedling lamp? How to choose the right technology? What should I look for when choosing plant lighting? Such questions are often asked by summer residents and gardeners. To begin with, it is necessary to determine the main types of appliances that are used in the modern dacha-garden economy:
The list does not contain ordinary incandescent bulbs. They cannot be used for highlighting seedlings. It is too energy consuming, they do not provide the desired radiation and emit too much heat. Some summer residents do combine them with other types of lighting, but this does not always provide the desired result.
Effective fitolampa for seedlings
The most effective phyto lamps for growing seedlings:
- LED lightening.
- Sodium lamps.
LED seedlings . Buy them, today, is not difficult. The stores presented a wide selection of them. They emit a special light to illuminate the rapidly growing sprouts during the winter short days. Many researches of scientists prove that one or another spectral colors affect the metabolic processes of plants in different ways. Such a lamp for illuminating seedlings should have strictly regulated ranges in order to most accurately replace the natural rays of sunlight. The main colors from the spectrum are blue and red. The wavelength of the blue spectrum should be 460 nm., And the length of the red - 660 nm. LEDs have exactly these colors in their pure form, and they significantly improve the photosynthesis of plants.
The basis of effective phyto-lighting this way are LED lamps. For seedlings it is best to use certified products. Buy such devices only in stores where you can request an official document. Experts say that phyto lamps for seedlings are the most progressive method of lighting up. Reviews of many gardeners say that using this technology, you can combine the spectra for any culture. Varieties of LEDs a huge amount. This allows you to combine the desired radiation.
The indisputable advantage of this innovative technology is cost-effectiveness and the ability to create a backlighting of seedlings with LED lamps with their own hands. To do this, you need to buy a base - special phyto-LEDs or ready-made devices (E27), and a power supply unit (driver). You also need a cable with a cross section of at least 0.75, for three cores, a cap (if you use ready-made lamps), and a plug for connecting to the power network. Such lighting is made very simple. It is necessary to connect all components to one circuit by soldering with a soldering iron and insulate the exposed places with electrical tape.
It is recommended, for more efficient illumination of seedlings with LED lamps and concentration of radiation, to make a small box of cone-shaped plywood, and to cover the walls with a reflective material (foil, nickel-plated metal plates). Complementing the seedlings with the help of LED phytolamps will help each summer resident to improve its quality and yield indicators in the future.Fluorescent lamps. For seedlings, this type of lighting is considered the most common and affordable. They serve for quite a long time, and it is not difficult to replace them. They have the shape of a glass tube, the walls of which are coated on the inside with a ball of a special substance called phosphor (phosphorus is its basis). It contributes to the conversion of energy into light rays. An inert argon gas and a small portion of mercury are pumped inside under high pressure, which, when heated, creates vapors that are dangerous to human health. That is why fluorescent lamps for seedlings after working out should not be broken or opened. They are sent to specialized enterprises for the processing and disposal of hazardous compounds.
The advantage of fluorescent lamps is their size. Different lengths allow you to choose a suitable seedling lamp. At home, apply short and medium. They can be installed on window sills or hung from the ceiling. Under them, trays are usually constructed so that light emission is sufficient. Lamps for seedlings with your own hands can be mounted from plywood or fiberboard plates. This will save money on the purchase of ready-made fixtures. The hand-made device in terms of functionality is not inferior to production analogues. To improve the quality of the scattering of rays, the inner part is covered with a foil ball.
The designs for daylight lamps are simple. Many are interested in the question - how to make a lamp for seedlings? It is enough to cook all the ingredients:
- Measure and scale the material in such a way that the lamp of the chosen length fits there.
- The sides of the box should be trapezoidal, and the body of the lamp resemble a cut cone. All parts can be fixed with wood glue or small metal corners.
- When the box is mounted, caps and starters are attached to the sides with screws or superglue. The power supply can be installed on the roof of the lamp.
- The inner surface should be pasted over with foiled paper or clean foil. For this you can use food foil.
- When the whole structure is ready, it is necessary to equip it with a cable with a plug for mains supply. After that, you can use it for its intended purpose.
It is necessary to install fluorescent lamps for additional lighting of seedlings at a height of 25-40 cm above the surface with placed trays. The distance must be adjusted, so it is recommended to make suspensions for lamps from flexible material. Many gardeners for this choose chains of metal, which is easy to manage and adjust the height.
Lamps are widely used to illuminate daylight seedlings in large greenhouses and greenhouses of agrotechnical enterprises, for which the cultivation of young saplings and garden crops is listed as a business. They allow you to cover quite large areas, providing the necessary light for many young plants. They are mounted very easily among themselves. You can buy ready-made lamps with built-in fluorescent lamps. In some enterprises, custom-made lamps are used, which are made under the ergonomics of industrial premises and best of all provide young plants with the necessary light.Sodium lamps. One of the safest for the eyes and human health, are used for lightening seedlings, both at home and on an industrial scale (large greenhouses). Sodium lamps are best suited for additional lighting of seedlings with a power not exceeding 100 watts. They emit mainly the red-orange spectrum of light. It is necessary for plants during flowering and the appearance of ovaries. They are very economical and long serve the benefit of the dacha economy.
The structure of the device is very complicated. It consists of a base, a glass cylinder and a burner (a cylindrical discharge tube). Inside the glass balloon are mercury and sodium vapor, which is ignited by creating an arc. During the heating of the sodium vapor using xenon stirring gas, a high pressure is created. The result of this process is the emission of orange or golden white shades.
The starting of the lamps is carried out under the activation of the electromagnetic or electronic starter. It can also be used IZU (pulse igniting device), which is sold with the device. Due to the relative bulkiness, many gardeners refuse to use sodium lamps, but they are very effective in complementary lighting of seedlings.
Energy saving lamps for seedling lighting
Current trends in the field of agrotechnical allow using energy-saving lamps for growing seedlings. At home, use ordinary household fixtures or create a special box with built-in plinths.
It should be noted that the main advantage of this technology is bispectrality (the ability to select and combine several types of lamps to ensure the emission of the required colors of the spectrum). Thus, it is possible to provide the plant with the following sources:
- By day. Ultraviolet radiation is necessary for plant illumination throughout the entire development period. Also, it is used as additional lighting of seedlings at any time of the day.
- Warm (red). Indispensable during the active flowering phase.
- Cold (blue). The colors of this spectrum are necessary at the initial stage of plant development - seed germination and the emergence of the first shoots.
One of the most effective energy-saving technologies for lightening seedlings are induction devices.Induction lamps . Often you can hear the question of which lamp for growing seedlings is best suited? More recently, another technology for lighting up young plants has appeared - induction (gas ionization using electromagnetic radiation). The light source is a plasma, which is created as a result of magnetic induction. Such devices can be considered as one of the most advanced, since they emit the two most sought-after colors from the spectrum (blue and red). They are also called bispectral (bicolor lamp for seedlings). In addition, induction lamps can heat up to 70 ° C. This advantage contributes to providing heat to the plants.
The choice of plant lighting technology for plants is a very important component of the quality growth and development of young plants. Seedlings under the lamp develops faster, especially during periods of short winter days or when there is a lack of daylight in greenhouses.
Principles of placement of seedlings lamps
There are several rules for installing a particular kind of seedling lamp. Illumination of plants should be carried out so that it does not harm them, but on the contrary, it helps. What should be done and what is most important to pay attention to when installing lamps:
- You can not install the backlight seedlings from the sides of the trays or containers. This can affect the evenness of the stems. All plants stretch to the light, therefore, with lateral artificial lighting, they can be deformed, bend down, bend. If the lighting is already mounted by this method, it is necessary to remove it and reinstall it so that the light is at the top.
- It is not allowed to install light sources far from seedlings. A sign of not respecting the distance (excess) are elongated stems and pale leaves. In this case, it is recommended to reduce this distance by about a third.
- Installing fixtures too close is also not recommended. This can lead to burns on the surface of the leaves of plants. If such signs show up, it is necessary to immediately increase the distance between the artificial light and the seedlings.
What lamp for seedlings to choose? To do this, it is recommended to view a short review of the most popular types of these devices from reliable manufacturers.
Overview of seedling lamps
To date, many manufacturers create a large selection of fixtures for illuminating seedlings. LED lamps, for example, are used quite recently, since this technology is only developing, but it has already found its use in gardening. This innovative method has the properties of bispectarism, which allows plants to provide the influence of two spectra at once, which are so necessary at the initial level of development of a young sprout. What to buy a lamp to illuminate the seedlings?
According to experts and experienced gardeners, the best LED (LED) lamps are:
- Philips . Leading global manufacturer of lighting equipment. Practically any device of this company can be suitable for lightening seedlings. The best model is the Philips MAS LEDtube.
- Electrum . The Swiss brand is also represented on the market for lighting seedlings. The best models of lamps: Electrum T8 24W G13 4000 (linear), 1.5W LC-4 GU 4 (capsular).
- Bellson . A Chinese manufacturer that has won its share of the lighting market niche. Top models: T8 LED G13 (linear lamp), LED G53, Industry E
- STARLIGHT . Another leading manufacturer of Chinese lighting products. Offers its products in more than 40 countries around the world. The best model for seedlings is the following model: Eco LT8-1040,
LED lamps for growing seedlings are very high quality, economical and durable. They are easy to install, so creating high-quality lighting does not make any special difficulties.
Among gas discharge sodium lamps - Reflaks for seedlings is the best solution. They stand out because they have a good effect on plants and do not irritate the eyes. They can equip their greenhouse or place in the house, which is allocated for seedlings, without any difficulties with his own hands. Bulbs are screwed into the usual base. The only drawback is that they require a pulse igniter, which is sold in the kit. Buy lamps for seedlings Reflax can be in any store lighting equipment. Many people are interested in the price of such light sources. It should be noted that the price of Reflaks seedlings is about 7,500 rubles.
The German manufacturer, Osram, is also engaged in the production of sodium devices, which represents the opportunity to purchase the best version of the device - the Plantastar 600W sodium lamp with E40 base.
Among the fluorescent lamps also have their own leaders. One of the best is the 18-watt Fluora. This lamp for growing seedlings, which you can buy in online stores, has worked well in many international exhibitions and forums. For additional lighting of plants, it is sufficient to install two such lamps per 1 m 2. It is one of the best in its niche market. Лампа Флора для рассады получила многочисленные отзывы дачников и сертификаты качества международных экспертов.
Также фитолюминесцентные лампы от производителя под названием PAULMANN пользуются большим спросом. Особенно в тренде модели от 40 до 100 Вт. Они слабо нагреваются и могут долго прослужить.
