Artificial lighting for seedlings grown on a windowsill is an absolutely necessary component of care. Organizing this process is more difficult than, for example, providing watering or loosening. To illuminate plants correctly, you must first carefully study their needs and characteristics. various types lamps. Let's find out how to choose a lamp for seedlings on the windowsill.
Is it possible to do without backlighting?
There is no hope that the seedlings on the brightest windowsill will receive the full amount of natural light.
The meager winter sun during a short day is absolutely not enough for normal growth and development of plants.
In addition, the light falling from the window causes the stems to stretch in one direction, so you have to constantly turn the container.
With a correctly positioned lamp, the lighting is diffused and the plants stretch upward. Natural light coming from a well-placed window can be enhanced to some level using a foil reflector, but in the morning, evening and in cloudy weather a lamp is indispensable.
What kind of additional lighting should there be for seedlings on the windowsill?
When organizing illumination of seedlings, three parameters are taken into account:
- Duration
- Intensity
- Light quality (spectrum composition)
Daylight hours winter time it is necessary to extend it so that it ranges from 12 hours to 17 hours for different plants. The optimal light intensity for most plants is 8000 lux.
With artificial lighting, 6000 lux is achievable, this is to obtain healthy seedlings enough.
The spectral composition is especially important. Sunlight contains a full spectrum, artificial light must contain the most important components for plants - red and blue.
Red promotes plant growth in length, is especially necessary during seed germination and early stages. The blue-violet spectrum intensifies photosynthesis, cells actively divide under its influence, and the stem thickens.
It is desirable that the design of the lamp allows changing high-quality composition light depending on the stage of plant development.
Types of lamps used when growing seedlings on a windowsill
There are many lighting devices available indoor plants, but none of them can completely replace the sun. You have to choose suitable option, taking into account all the advantages and disadvantages, including efficiency and ease of use.
An ordinary incandescent lamp is not suitable as a lamp for seedlings on a windowsill, as it does not provide the required spectrum and emits too much heat.
Luminescent or so-called fluorescent lamps produce a certain amount of red in the spectrum, do not emit heat, are economical and durable.
Flaw - low power, To obtain required level illumination, you have to install a number of such lamps, which is not very convenient.
Phytolamps, currently quite popular lamps, also belong to the category of fluorescent, but are designed specifically for plants and are ideal in terms of light quality; they produce a violet-pink spectrum - exactly what is needed.
Such light is harmful to humans, so phytolamps must be equipped with a reflector - a screen that screens the lamp from the eyes and at the same time enhances the illumination in the desired area.
You can purchase a ready-made reflector or make it yourself from mirrors or foil attached to a frame. The matte screen is good because it makes the lighting more uniform.
Sodium metal halide lamps high pressure, for example “Reflax”, are available in several versions, differing, among other things, in the composition of the spectrum. Some of them provide regulation of the light level using a reflector.
The cost of metal halide devices is low, and they consume little energy. High-pressure sodium lamps are much more expensive and require a power regulator in addition to them, but the results from their use are very good due to their high power and adequate spectrum.
Lighting LED lamps- a modern, popular and most promising method that combines the advantages of others. The main one is the ability, by combining elements, to obtain light of almost any composition, moreover, powerful and uniform.
With the help of LEDs, you can provide your seedlings with ideal lighting conditions if you have basic knowledge about the needs of plants and experiment a little. It is not difficult to assemble such a lamp with your own hands, and then it will not cost much. Energy LED lamp consumes three times less than fluorescent, and has a service life of more than 10 years.
Manufacturing and installation of LED lamps
To make a device with your own hands, you need to buy the required number of LEDs in the store.
To be able to provide the most complete spectrum, and apply it to different stages cultivation, practitioners advise purchasing: 30 red (3GR-R), 10 white (3HP2c 3800 - 4000K), 10 pure white (4800 - 5300K), 20 blue (3GR-B) LEDs.
From such a set it is convenient to make various combinations in the direction of shifting blue or red. At the beginning of germination, before the picking stage good results shows alternating red and blue diodes in a 2:1 ratio. After picking, a softer light is recommended - 1:1.
The LEDs are combined into a circuit using a soldering iron and connected to a power supply that acts as a stabilizer. Using hot glue or bolts, they are attached to a base, which can be, for example, an aluminum strip or a regular ruler.
If you arrange them in two rows, the lighting will be more uniform. The distance between the elements must be maintained such that the lighting zones slightly overlap, without leaving dark gaps. A cord with a plug and a switch is connected to the power supply.
Installation of fluorescent lamps
Couple fluorescent lamps fixed on wooden block approximately 4 cm thick. Electronic ballast is fixed on its upper surface, in an area inaccessible to moisture. According to the diagram indicated on it, the lamps are connected using contact pads.
The lamps are carefully inserted into clips pre-attached to the bar. It is advisable to equip the lamp with a reflector. It is better to hang the device not on hinges, but on chains, so that you can change the height of its location.
You can connect a store-bought timer to the lamp so that the lighting mode is adjusted automatically.
Lamp arrangement and backlight control
Artificial lighting allows you to place boxes with seedlings in 2 or 3 tiers to make more economical use of space on the windowsill.
For this purpose they are made from wooden beam a rack consisting of a number of shelves. The lamp is suspended above each box, attached to the bottom of the tier above.
The degree of illumination can be adjusted using the distance between the lamp and the seedlings, but it should not be less than 15 cm.
With a lack of light, the stems stretch excessively upward, they are thin and weak; in normal light, they are strong and dense.
As the seedlings grow, the light source will have to be raised; this possibility must be provided for in the design of the lamp and shelving. If the lamp produces heat, it should not be felt by the palm of your hand at the plant level.
There is no point in turning on the lamp when the additional lighting is not noticeable to the eye, this means that there is enough natural light.
In order to obtain early seedlings, the seeds should be planted as early as January–February; the specific timing depends on the type of plant.
To create a healthy, well-developed plant, several conditions must be met:
- temperature regime. Selected taking into account the plant, may have significant fluctuations in readings day and night;
- air humidity indicators, watering and spraying regimes;
- length of daylight hours.
We will not consider how to regulate the first two components in this article, we will only talk about optimal modes light lighting.
Over many hundreds of millions of years, plants have adapted to solar radiation. It is its parameters that are most favorable for them; any deviations will certainly affect their development. Solar radiation consists of visible and invisible waves. Visible waves include light; the invisible spectrum includes infrared and ultraviolet waves, gamma and beta radiation. The absence of at least one component for plants becomes a stressful situation; all gardeners need to know this before choosing lighting lamps.
Currently, there are several fundamentally different types of lamps; sometimes it is difficult to choose among them the best option for illuminating seedlings. The light from which lamps is most favorable for plants?
Rest modern lamps It’s not worth considering; in terms of their performance characteristics, they are significantly inferior to LED ones.

What color should the lighting be for seedlings?
This is a very important topic that deserves detailed consideration. You need to find out all the nuances, and only then start making illumination for the seedlings. You can find recommendations to use monochrome blue and red lamps, only they ensure optimal plant growth.
What really?
Firstly, For the normal development of plants, the entire spectrum of solar radiation is needed, and plants choose which one to use at a given phase of development on their own; over the course of evolution, they have learned to do this much better than man. The plant will never be able to tell which waves are not enough for them and which ones are in excess. It will be possible to notice this only after growth is suppressed, that is, it is too late.
Secondly. Any seedlings before planting in open ground must undergo gradual acclimatization and hardening in the fresh air. Plants get used not only to air temperature, but also to natural light; the hardening process is always stressful. Why add light stress to temperature stress yourself?
Third. Monochrome LED lamps are much more expensive than ordinary ones. There may be a situation where the backlight will be much more expensive ready seedlings purchased in a store or market. Why then engage in self-cultivation?
LED lamps already have a rather limited spectrum of waves; we advise you to check them before making the backlight. To do this, pass a narrow beam of light through a transparent prism; the output should be a rainbow of all colors and their shades. Such a lamp will create maximum comfortable conditions for seedlings. If these questions are clear, you can start making the lighting yourself.
Step-by-step instructions for making the backlight
First you need to decide on the number of seedlings and their location. It is recommended to place it on the windowsill, in this place the plants will not receive a large number of natural sunlight, which no lamps can fully replace (we talked about this above). It is this situation that we will take as the initial conditions.
Step 1. Calculation and procurement necessary materials. To make the backlight you will need LED lamps, sockets, electrical cables, a switch, and a plug.
For the screen you need to prepare plywood approximately 2 mm thick and foil.
The device must be fixed to telescopic tripod, if it is difficult to find, then you can make your own stop with the ability to move the lamps in height.
There is no need to buy devices that measure illumination; you will have to use the experience of practitioners. For lighting, it is enough to purchase 3 W LED lamps. They can be placed at a distance of 30–40 cm from each other, this will create a fairly powerful luminous flux; the intensity of the flux can be regulated by raising/lowering the lamps. If you plan to plant seedlings of very light-loving plants, you can buy 5–6 W lamps as a reserve.
Step 2. Remove the plastic cover from the llamas, which collects the rays into one stream. In our case, we need diffused light. Depending on the manufacturer, the trim may be screwed or snapped into place.
Step 3. Make a reflector. It will perform two functions: make the light more uniform over the entire area and serve as a frame for fixing electrical fittings. The reflector can be made of plywood, fiberboard or thick cardboard, internal surfaces covered with foil. How to make it?
Important. If the reflector is made of cardboard, then the bottom needs to be strengthened - light bulbs, sockets and electrical cables can deform it. For reinforcement, you can use a thin wooden strip: attach it with reverse side to the cardboard element with a stapler or small nails.
Step 4. Collect everything individual elements reflector. If they are made of plywood, then it is more reliable to assemble them with glue; if they are made of cardboard, then adhesive tape is enough.
Step 5. WITH inside Cover the reflector with foil. You should not try to make it very even; existing bends will further scatter the light.
Step 6. Insert the cartridges into the holes and tighten them with a special mounting nut, check that all components are securely fastened.
After this, you can proceed to connecting electrical cables. No special knowledge is required, but the work should be carried out in compliance with the rules of the PUE. It is advisable to do the wiring from inside the reflector. There are no high temperatures there, there is no need to be afraid of cable overheating, but in such a place electrical contacts children will not be able to get there.
The light bulbs must be connected in parallel; for this you need to use a terminal block. The number of terminals must correspond to the number of cartridges. Before starting the connection, you should prepare the wires; to do this, cut them to length, taking into account the location of each cartridge. Remove the insulation from the ends and prepare the cable for connection. Connect all the lamps one by one and use a tester to check the correct connection. Everything is fine - you can connect a long wire with a plug and a switch. An ordinary 1–2 A pendant switch will do; the power of all light bulbs is very low.
Important note. Carefully check the reliability of the connection; each connecting bolt must be tightened at least twice. All visible connections should be insulated, and access to live wires should be completely excluded.
Install the switch in a place convenient for use; it should always be easily accessible and not interfere with the development of seedlings.
How to use homemade lighting
The development of seedlings depends on the composition of the soil, irrigation scheme, fertilizers used, temperature regime and lighting. Let's focus on the last factor; it is this that can be controlled using backlighting.
As soon as it appears personal experience growing seedlings using lighting, you can independently experiment with different lighting modes.
We have reviewed the manufacture of the most simple option backlight. If you understand in carpentry, then you can make more functional and durable backlight options from wooden slats with several degrees of freedom. They will be adjustable not only in height, but also in the angle of inclination of the lamps.
Use for illumination of phytolamps
Absolutely new development, illumination has a narrow spread in wavelength for each growth phase. We already dwelt a little on this topic earlier in the article. If you wish, you can use phytolamps when making the lighting, but you should not expect a significant improvement in the quality of the seedlings. Such lamps are considered a promotional product of manufacturers. Remember the “unique” UFO heaters. Ordinary spiral heaters are sold for a huge price, the cost of which is several orders of magnitude lower, and all the operational characteristics and physical principle of operation are absolutely the same.
Video - Illumination of seedlings with LED lamps
- This is a priority question for both beginners and experienced ones. Light is one of the most important components active growth and healthy cultural development. When providing illumination for seedlings, it is advisable to have an idea of what light spectrum is needed and as close as possible to sunlight.
The simplest backlight
Today, gardeners prefer to make phytolights themselves: firstly, this is a significant saving for the family budget, and secondly, by studying the characteristics of various artificial light sources, you can choose the most useful combination.
The simplest way to provide light for seedlings is to place them on the windowsill. To ensure that plants receive maximum light, use the simplest device. In normal cardboard box cut off the top and bottom sides, leaving only the side ones. The sides of the box are covered with foil. Containers with seedlings are placed inside the box, preferably its sides are higher than the containers with vegetation. This entire structure is located on the windowsill.
Sunlight hitting the foil is refracted and reflected on the seedlings. This method is economical and simple, but in cloudy weather it is absolutely useless. Foil itself will not provide illumination for plants.
Growing under artificial light
The main condition for artificial lighting is maximum similarity to the emission spectrum of sunlight.
Necessary for the growth, development of cells and tissues in the natural spectrum are red and blue colors. Before making a phytolamp with your own hands, you should take this fact into account.
What should the rack be like?
The rack on which the seedlings will be located and the structures with lamps must meet the following criteria:
- strength and stability;
- invulnerability to moisture;
- ease of access to all shelves;
- correspondence of distances between light and plantings;
- durability.
Lamp selection
To make a phytolamp for plants with your own hands, you need to purchase a lamp that has suitable characteristics. To increase sales, unscrupulous manufacturers call ordinary incandescent lamps phytolamps.
When choosing a light source, carefully inspect the packaging; it always indicates the color temperature value:
- warm ones with a red spectrum have an indicator of 2000 K;
- cold with blue - closer to the value of 8000 K.
For example, a lamp with a value of 2700 K helps strengthen shoots and form peduncles; a value of 6500 has a greater effect on the root system, its development and strengthening. The most popular backlight lamps:
- luminescent;
- sodium;
- metal halide;
- LED
Did you know? The impetus for the appearance of LEDs was the discovery of luminescence by Soviet physicist Oleg Losev in 1923. Scientific journals in Germany, where the scientist’s articles were often published, called this discovery Losev Licht. Later in the early 70s, thanks to Losev's discovery, red, yellow and green LEDs appeared. The blue LED was created by Suji Nakamura in 1990.
The advantages of lighting are undeniable; most plants initially need light at least 12 hours a day, and daylight hours do not always provide this opportunity. 
Without light, the seedlings will stretch out, all the plant’s efforts will be spent on growth, and not on the development of future fruits. Therefore, for normal, stage-by-stage development, as in the natural environment, seedlings are illuminated at home.
Making a rack
Building a rack with your own hands is convenient in all respects: right size, material, appearance. The construction itself does not take much time. 
So, let's buy at hardware store bars, thick plywood for shelves, fasteners. You can fasten the parts together with self-tapping screws. The length and width of the shelves are determined based on the length and number of your seedling boxes. For convenience, make a drawing with the necessary measurements.
To work you will need tools:
- hand or circular saw;
- screwdriver;
- drill;
- simple pencil.
Since you will not need a rack all year round, giving it the most aesthetic appearance, at other times it can be used as an interior item, for example, under books or decorative trinkets. 
In order to be able to move it from place to place, you can give it mobility using special wheels for furniture.
Today, among gardeners, LED lamps are considered the most popular lighting for seedlings; they are easy to make with your own hands, and you can also combine different spectrums of light.
Advantages of LEDs:- as close to sunlight as possible;
- operate without interruptions or defects;
- economical - consume little energy;
- even at a fairly close distance they do not cause burns to foliage.
To make an LED lamp for seedlings with your own hands you will need: - blue and red diodes;
- thermal paste;
- aluminum or any other profile for fastening;
- power supply, cord and plug;
- soldering iron and solder;
- bolts.
Natural lighting occupies one of the first places in the life of all living organisms, but not all living things can move in order to be under the sun for the required amount of time. We will talk about those who are in a phase of active growth and need additional lighting, which lamps for them will help provide.
The importance of lighting
Everyone knows that light is an important component for growing strong seedlings. And in winter and in early spring When new plants are gaining strength, the natural sunny day is quite short.
In this case, additional light sources, such as lamps, come to the rescue. necessary in accordance with the stage of development and the purpose of cultivation, therefore the choice must be made consciously.
Each color of the light spectrum has its own characteristics:
- red and blue - stimulate metabolic processes, increase chlorophyll production, accelerate photosynthesis;
- orange - accelerates fruiting, used in winter to accelerate the ripening of fruits;
- yellow and green are important colors during growth and are easily reflected by seedlings;
- ultraviolet - has a bactericidal effect, inhibiting the growth of harmful organisms.
Did you know? Illumination of plants using lamps was first used in 1868. This was done by a scientist from Russia Andrei Famintsin.
Despite the fact that each plant has its own specific requirements for the light spectrum, if there is a lack of light, photosynthesis slows down, biomass grows slowly, and seedlings begin to get sick. A suitable illumination level is 8 thousand lux. Modern technologies, namely illumination of plants at home, will help to bring the seedlings as close as possible to the desired parameters and achieve illumination of 6 thousand lux.
Primary requirements
Having decided to grow your own seedlings at home, it is important to know what to look for when choosing additional light sources. Let's consider how The lamp must meet the following requirements:
- for full growth, it is better to choose devices that emit red or blue light;
- the main purpose of the additional light source should be lighting, and not drying out and increasing the air temperature;
- the rays of light should be soft;
- The container must be illuminated evenly and completely.
To obtain high-quality seedlings, you need to correctly calculate the duration of additional illumination, which will depend on the power of the device, as well as the distance from it to the surface. You can check the thermal radiation of the device by placing your hand on the surface that is illuminated, and thus feeling the heat.
Are any or types of lamps suitable for lighting seedlings?
Today the market is saturated with different lighting fixtures, which help to get the right amount of light. However, many are interested in how to choose the right device for illuminating seedlings and what features popular models have.
Important! Any selected type of lighting can be equipped with light screens to save energy. To create them, just stick foil or regular white cardboard on the sides of the container.
Some people think that in order for the plants to receive the right amount of light and heat, it is enough to hang several ordinary lamps over the seedlings. However, ordinary devices do not have the necessary color spectrum for complete illumination of plants.
Consuming a fairly large amount of electricity, they convert only 5% of the light, and convert the rest into heat. As a result, the plants do not receive light, but additional heat and, as a result, overdrying or burns on the leaves occur. Therefore, the use of incandescent lamps is not as efficient as others that are gaining popularity today.
Luminescent
one of optimal options to obtain ultraviolet light, which is so necessary for plants. Thanks to this effect, intensive growth of seedlings of rich color will occur. In whom, this color leads to a decrease in the level of pathogenic microbes.Additional advantages of use are the absence high temperature near the lamp, which makes it possible to maintain the desired microclimate around the plants. Despite the positive aspects, such lamps still have some disadvantages. These include the absence required quantity waves in the red part of the spectrum.
Also they do not have high power, and therefore quick results You can't get it with them. To obtain the desired result, the distance from the lamp to the seedlings should be within 20–30 cm. The ideal power is 40 W.
Sodium
Sodium lamps are considered the brightest compared to others. Their emission spectrum optimally supports plant growth. They are divided into two types: low and high pressure. It is the latter that are used to add additional lighting to seedlings at home and accelerate the ripening of fruits.
Some representatives of this group have a mirror reflector, which allows illumination of a large area, which saves cash. The negative aspects of use are strong heating and unsafe use, since mercury and a mixture of sodium are used in production.
These lamps cannot be turned on if there are voltage drops of more than 10%. Temperature drop environment leads to a decrease in the efficiency of such lamps. The lamp power should be no more than 100 W.
Important! Lamps with sodium lamps It is strictly forbidden to plug into simple sockets. For them, you need to use special equipment, chokes and pulsed ignition devices.
LED
LED lamps for seedlings are gaining popularity among farmers. Using similar lighting on seedlings leads to the following results:
- reduction of electricity consumption;
- thanks to minimal heating, the lamp can be placed almost near the plants;
- the lamp contains diodes of different colors, which allow you to obtain red and blue colors at the same time;
- high operational safety minimizes possible losses;
- absence of drying and excessive thermal humidity;
- no minimum infrared radiation.
Phytolamps
Phytolamps are complex devices, their price directly depends on technical characteristics: power, brightness, dimensions, angle and area of illumination, heating of the body and service life. Having decided to purchase such a device and being in search of information on how to choose a phytolamp for seedlings, it is important to take into account all of the above characteristics.
Without bright light, nothing can survive living plant. If we talk about seedlings and seeds, then additional lighting at home can work real miracles. A lack of sunlight in winter and spring is detrimental to plants. Young stems will stretch towards the sun with all their might, which can lead to their thinning. Lack of light can also cause “black leg” or even death of seedlings.
It is of great importance which lamps are used to provide additional illumination for plants. Too bright a lamp will burn them, and ordinary incandescent lamps consume a huge amount of electricity.
Some seeds need to be planted in the last weeks of January. This time of year in our latitudes is characterized by minimum quantity sunny days, which pushes gardeners to install additional lighting for vegetation at home. It will take very little effort and time, but the result will be colossal.
Benefits of supplementary lighting:
- Increasing the duration of daylight hours, which is necessary for early forcing.
- Ensuring uniform illumination of vegetation, which prevents strong stretching of stems and the appearance of various pathologies.
- The correct spectrum guarantees the seedlings the full formation of young and fragile stems into mature, strong crops.
- Illuminated plants are hardy and are not exposed to infections and dangerous microorganisms.
- The harvest obtained from one stem grows.
Having convinced themselves of the need to install lighting, gardeners begin to think about what kind of lamp they should use. An ordinary light bulb is not suitable for these purposes; its light is incomplete and does not give the required effect. The lighting should closely resemble the natural spectrum of sunlight.
The spectral layout of light has the following effects on plants:
- Red spectrum. Promotes growth and development of the root system. The fruits begin to actively form and ripen.
- Blue-violet spectrum. Inhibits too rapid growth of the stem cellular level. Stimulates stem cell division. As a result, the plant does not stretch, deteriorate or become thin.
- Green, yellow and orange spectra. Does not have a significant effect on seedlings.
All spectra together produce strong effect, they affect the growth and development of vegetation. Ordinary light bulbs do not have the required range of colors. But especially for gardeners who grow seeds at home on their own, there are special lamps for seedlings.
How to organize lighting for seedlings at home with your own hands
To organize the lighting yourself, you must first build a space for seedlings. You can select a separate window sill, build a small shelving unit, or free up a table near the window. The next step will be to develop mounting methods for the lamps. These can be hooks or small “ears”. The main thing in this matter is convenience and reliability. The final stage An electrical cord from the network or generator will follow. Once all the preparations are done, it's time to start working on the lamps.
For illumination, lamps can be used: DNA3, LEDs and metal halide. These bulbs are often used to provide additional lighting to plants in greenhouses. large sizes. For home use, it is better to purchase LED, fluorescent or phytolamps.
More information about the types of lamps that are suitable for home lighting of seedlings:
- Phytolamps. The perfect solution for additional illumination of stems. The pink-violet spectrum is dangerous for the human body, so special reflectors must be installed along with these lamps.
- High pressure sodium lamps. Give seedlings uniform warm light. Requires installation of special power regulators. The price of products can hit your pocket hard.
- LED light bulbs. They are accessible to every gardener, economical and have many advantages over their counterparts.
- Fluorescent lamps. They are poor in the red spectrum, so among those listed they occupy the last line in the list. Use them only when absolutely necessary.
For an ordinary gardener, it is best to install lighting in an apartment with LED bulbs. This option is the most economical, safe, effective and easy to implement. What are the other advantages of this type of lamps, and how can you build full-fledged lighting for plants at home?
What are the advantages of LED lamps
- LEDs have gained immense popularity due to good lighting. In addition, they do not increase the temperature of the air around them. Such lighting gives the gardener many positive aspects. For example, when making a lamp at home, you can combine two effective spectrums. The result is an almost ideal light bulb for plants.
- LEDs can be found in any construction or hardware supermarket. In addition, their price is quite affordable. If the lamp burns out, replacing it will not become an overwhelming burden for the average gardener in our country. The cost of the LED pays off very quickly.
- Working diode lamps will not affect your electricity bill in any way. At the same time, the amount of light they provide to vegetation is in no way inferior to other types of lamps. For harmonious growth of seedlings, about six thousand lux is required. Diodes quietly give out this indicator.
- Last on our list, but not least for ordinary gardeners, is ease of installation and ease of operation.
How to make an LED lamp for seedlings with your own hands
Making a simple strip light is quite simple. To do this you will need the following elements:
- plug and wire;
- power supply or driver that will provide uninterrupted voltage;
- base for the lamp (any wooden or plastic base: ruler, furniture profile, plinth);
- special thermal paste or a more expensive option - hot melt adhesive (found at a hardware store);
- blue and red diodes.
In order for the red and blue spectrum to evenly affect the plant, it should be distributed on the base in the following order: two red, one blue, and so on.
The elements are connected by soldering, connected to the power supply, plug and switch. The tape is secured to the prepared surface using bolts and rivets. Double tape holds the structure in place perfectly. The last step is to assemble a single circuit with a block, wire, switch and plug.

Phytolamps for supplementary illumination of plants at home
Externally, phytolamps resemble LED ones. Their main difference is the spectrum of the glow produced, which in phytolamps is pink-violet. The light should fall directly on the plants from above. The backlight height must be adjusted manually.

In order not to destroy the plants and get a strong and strong seedlings, it is important to follow the rules.
- It is imperative to observe the frequency of illumination: day and night. A sharp change or shift in the schedule is fraught with poor development and complete destruction of vegetation.
- The gap between the light bulb and the plant obeys the inverse quadrant law. This means that if the lamp is removed to a distance four times smaller, the intensity of light received by vegetation will decrease by sixteen times.
- If it is possible to place vegetation near windows facing south, this will increase the effectiveness of additional lighting. In addition, this will save on electricity.
- Study the additional lighting regime for the seedlings you are growing. Each type of plant needs a certain amount of light. The duration of photoperiods is also different for everyone. Vegetables need light during the day. There are plants that like to be in the shade most time.
- Please pay attention Special attention lighting seedlings on days when there is no sun at all. If the windows are on the north side, then home lighting is simply necessary.
It is important to remember that natural Sun rays no light bulb can replace it.
