Artificial lighting for seedlings grown on the windowsill is an absolutely necessary component of care. Organizing this process is more difficult than, for example, providing irrigation 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 window sill seedling light.
Is it possible to do without backlight?
It is not necessary to hope that on the lightest windowsill the seedlings receive the full norm of natural light.
The meager winter sun during a short day is categorically not enough for the normal growth and development of plants.
In addition, the light falling from the window makes the stems stretch in one direction, you have to constantly turn the container.
With a properly positioned lamp, the lighting turns out to be diffused, and the plants stretch upwards. Natural light coming from a well-placed window can be amplified to some level with a foil reflector, but in the morning, evening and on cloudy days, a lamp is indispensable.
What should be the additional lighting of seedlings on the windowsill?
When organizing the illumination of seedlings, three parameters are taken into account:
- Duration
- Intensity
- Light quality (spectrum composition)
light day in winter time it is necessary to extend it so that it is for different plants from 12 hours to 17 hours. The optimal light intensity for most plants is 8000 lux.
With artificial lighting, 6000 lux are achievable, this is to obtain healthy seedling enough.
The spectral composition is especially important. Sunlight contains a full spectrum, artificial should contain the most important components for plants - red and blue.
Red promotes the growth of the plant in length, it is especially necessary for seed germination and for early stages. The blue-violet spectrum intensifies photosynthesis, cells actively divide under its influence, the stem thickens.
It is desirable that the device of the lamp allows you to change qualitative composition light depending on the stage of plant development.
Types of lamps used when growing seedlings on the windowsill
There are many devices for lighting indoor plants, but none of them can completely replace the sun. I have to choose suitable option, taking into account all the advantages and disadvantages, including cost-effectiveness and ease of use.
An ordinary incandescent lamp, as a lamp for seedlings on a windowsill, is not suitable, as it does not give the desired spectrum and emits too much heat.
Fluorescent or the so-called fluorescent lamps give out a certain amount of red in the spectrum, do not emit heat, are economical and durable.
Flaw - low power, To obtain desired level illumination, you have to install a number of such lamps, which is not very convenient.
Phytolamps, quite popular at the moment, also belong to the fluorescent category, but designed specifically for plants and ideal in terms of light quality, they give a violet-pink spectrum - exactly what you need.
For a person, such light is harmful, so phytolamps must be equipped with a reflector - a screen that blocks 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 your own from mirrors or foil fixed to the frame. The matte screen is good because it makes the lighting more uniform.
Sodium metal halide lamps high pressure, for example "Reflux", are produced in several versions, which differ, among other things, in the composition of the spectrum. Some of them provide for the regulation of the level of illumination using a reflector.
The cost of metal halide devices is low, 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 the high power and adequate spectrum.
Lighting LED lamps- a modern, popular and most promising way, combining 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 a basic knowledge of the needs of plants and a little experimentation. It is not difficult to assemble such a lamp with your own hands, then it will be inexpensive. Energy LED lamp consumes three times less than fluorescent, and the service life is more than 10 years.
Manufacturing and installation of LED lamps
To make a device with your own hands, you need to buy the right number of LEDs in the store.
To be able to provide the most complete spectrum, and apply it to different stages cultivation, practitioners are advised to purchase: 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 the alternation of red and blue diodes in a ratio of 2:1. After picking, a softer light is recommended - 1: 1.
Using a soldering iron, the LEDs are combined into a circuit and connected to a power supply that acts as a stabilizer. Using hot glue or bolts, they are attached to the base, which can be, for example, an aluminum bar or a regular ruler.
If you arrange them in two rows, the lighting will turn out to be more uniform. The distance between the elements must be maintained such that the lighting zones overlap slightly, leaving no dark gaps. A cord with a plug and a switch is connected to the power supply.
Installation of fluorescent lamps
Couple fluorescent lamps fix on wooden block about 4 cm thick. An electronic ballast is fixed on its upper surface, in a zone inaccessible to moisture. According to the scheme indicated on it, the lamps are connected by means of contact pads.
The lamps are carefully inserted into the clips previously fixed on 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.
A store-bought timer can be connected to the luminaire so that the lighting mode is adjusted automatically.
Location of luminaires and backlight control
Artificial lighting allows you to place boxes with seedlings in 2 or 3 tiers to save space on the windowsill.
For this, they are made from wooden beam rack consisting of a number of shelves. A lamp is hung 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 are unnecessarily stretched upwards, 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 should be provided for in the design of the lamp and the rack. If the lamp emits heat, then at the level of plants it should not be felt with the palm of your hand.
It makes no sense to turn on the lamp when the additional illumination is not visible to the eye, this means that there is enough natural light.
In order to receive early seedlings, the seeds should be planted as early as January-February, the specific dates depend on the type of plant.
To create a healthy, well-developed plant, several conditions must be met:
- temperature regime. It is selected taking into account the plant, may have significant fluctuations in readings day and night;
- indicators of air humidity, irrigation and spraying modes;
- day length.
We will not consider how to regulate the first two components in this article, we will only talk about optimal modes light illumination.
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 development. Solar radiation consists of visible and invisible waves. Visible waves include light, 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 summer residents need to know this before choosing lighting lamps.
Currently, there are several fundamentally different types of lamps, sometimes it is difficult to choose the best option among them for illuminating seedlings. The light from which lamps is the most favorable for plants?
Rest modern lamps it is not worth considering, in terms of their performance characteristics they are significantly inferior to LED ones.

What color should be the lighting for seedlings
This is a very important topic that deserves detailed consideration. You need to find out all the nuances, and only then proceed to the manufacture of seedling illumination. You can find recommendations to use monochrome blue and red lamps, only they provide optimal plant growth.
What is real?
Firstly, for the normal development of plants, the entire spectrum of solar radiation is needed, and which one to use at this phase of development, plants choose on their own, during evolution they have learned to do this much better than a man. The plant will never be able to tell which waves are not enough for them, and which are in excess. It will be possible to notice this only after growth inhibition, that is, it is already too late.
Secondly. Any seedling before planting in open ground should 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 on your own?
Third. Monochrome LED lamps are much more expensive than ordinary ones. There may be a situation where the backlight will be much more expensive finished seedlings bought 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 the maximum comfortable conditions for seedlings. If these questions are clear, you can start making the backlight with your own hands.
Step-by-step instructions for making backlight
First, you should decide on the number of seedlings and their location. It is recommended to place it on the windowsill, in this place the plants will be able to receive a large number of natural sunlight, which no lamps can fully replace (we talked about this above). It is this position that we will take as the initial conditions.
Step 1. Calculation and procurement necessary materials. To make the backlight, you will need LED lamps, cartridges, electrical cables, a switch, a plug.
For the screen, you need to prepare plywood about 2 mm thick and foil.
The device must be fixed to telescopic tripod, if it is difficult to find, then you can independently make an emphasis with the ability to move the fixtures in height.
It is not worth buying devices that measure illumination; you will have to use the experience of practitioners. For lighting, it is enough to purchase LED lamps with a power of 3 watts. They can be placed at a distance of 30–40 cm from each other, this will create a fairly powerful light flux, the flux strength is regulated by raising / lowering the lamps. If you plan to plant seedlings of very light-loving plants, then you can buy lamps with a power of 5-6 W in stock.
Step 2 Remove from the lamas a plastic pad that collects the rays in one stream. In our case, diffused light is needed. Depending on the manufacturer, the overlay may twist or sit on the latches.
Step 3 Make a reflector. It will perform two functions: to make the light more uniform over the entire area and to serve as a frame for fixing electrical fittings. The reflector can be made from 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 reinforced - light bulbs, cartridges and electrical cables can deform it. For reinforcement, you can use a thin wooden rail: attach it with reverse side to the cardboard element with a stapler or small carnations.
Step 4 Gather 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, the existing bends will additionally scatter light.
Step 6 Insert the cartridges into the holes and tighten them with a special mounting nut, check the reliability of fastening of all nodes.
After that, you can proceed to connect the electrical cables. Special knowledge is not required, but the work should be carried out in compliance with the rules of the EIC. It is advisable to make wiring from inside the reflector. There are no high temperatures there, you should not be afraid of overheating of the cables, but in such a place to electrical contacts children cannot reach.
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, for this, cut them to length, taking into account the location of each cartridge. Remove the insulation at the ends and prepare the cable for connection. Connect all the fixtures in turn, using a tester, check the correct connection. Everything is fine - you can connect a long wire with a plug and a switch. An ordinary 1-2 A hanging switch will do, the power of all the bulbs is very small.
Important note. Carefully check the reliability of the connection, each connecting bolt must be tightened at least twice. All visible connections must be insulated, and access to live wires must 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, the irrigation scheme, the fertilizers used, temperature regime and lighting. Let's dwell on the last factor, it is it that can be controlled with the help of backlighting.
As soon as it appears personal experience growing seedlings using backlighting, you can already independently experiment with different lighting modes.
We have considered the manufacture of the most simple option illumination. If you understand in carpentry, then you can make more functional and durable lighting options from wooden slats with several degrees of freedom. They will be regulated not only in height, but also in the angle of inclination of the lamps.
Use for lighting phytolamps
Absolutely new development, the illumination has a narrow wavelength spread for each growth phase. Above in the article, we have already dwelled on this topic a little. If you wish, you can use fitolamps during the manufacture of lighting, but you should not expect a significant improvement in the quality of seedlings. Such lamps are considered an advertising product of manufacturers. Remember the "unique" UFO heaters. For a huge price, ordinary spiral heaters are sold, the cost of which is several orders of magnitude lower, and all performance characteristics and the physical principle of operation are exactly 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 desirable 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 phytolamps on their own: firstly, this is a significant savings for the family budget, and secondly, having studied the characteristics of various artificial light sources, you can choose the most useful combination.
The easiest way to provide light for seedlings is to place them on the windowsill. In order for plants to receive maximum light, they use the simplest device. In normal cardboard box cut off the upper and lower sides, leaving only the side. The sides of the box are covered with foil. Containers with seedlings are placed inside the box, it is desirable that its sides are higher than the containers with vegetation. The whole structure is located on the windowsill.
Sunlight, falling on the foil, is refracted and reflects on the seedlings. This method is economical and simple, but in cloudy weather it is absolutely useless. By itself, the foil will not provide illumination for plants.
Growing under artificial light
The main condition for artificial lighting is the maximum similarity with the radiation spectrum of sunlight.
Necessary for the growth, development of cells and tissues in the natural spectrum are red and blue colors. Before you make a phytolamp with your own hands, you should take into account this fact.
What should be the rack
The rack on which the seedlings will be located, and 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 landings;
- durability.
Lamp selection
To make a phytolamp for plants with your own hands, you need to purchase a lamp that is suitable for its characteristics. Unscrupulous manufacturers call ordinary incandescent lamps phytolamps to increase sales.
When choosing a light source, carefully inspect the packaging, it always indicates the value of the color temperature:
- warm 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 to strengthen the shoots, the formation of peduncles; a value of 6500 has a greater effect on the root system, its development and strengthening. The most popular light bulbs:
- luminescent;
- sodium;
- metal halide;
- LED.
Did you know? The impetus for the appearance of LEDs was the discovery of luminescence by the 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 backlighting are undeniable, most plants need light at least 12 hours a day at the beginning, and daylight hours do not always provide such an opportunity. 
Without light, seedlings will stretch out, all the efforts of the plant will be spent on growth, and not the development of future fruits. Therefore, for a normal step-by-step, as in the natural environment of development, seedlings at home are illuminated.
We make a rack
Do-it-yourself shelving is convenient in every way: right size, material, appearance. The building itself does not take much time. 
So, we buy 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 made, focusing on the length and number of their 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 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 with the help of 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, in addition, combine a different spectrum of glow.
Benefits of LEDs:- as close as possible to sunlight;
- work without interruptions and defects;
- economical - consume little energy;
- even at a fairly close distance, they do not cause burns to the foliage.
To make your own LED grow light, 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 stay under the sun for the right amount of time. We are talking about those who are in the phase of active growth and need additional lighting, which lamps will help them 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. need 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 the production of chlorophyll, accelerate photosynthesis;
- orange - accelerates fruiting, used in winter to accelerate fruit ripening;
- 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? For the first time, additional illumination of plants with the help of lamps was applied 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, with a lack of it, photosynthesis slows down, biomass slowly grows, and seedlings begin to get sick. 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.
Primary requirements
Having made the decision to independently grow seedlings at home, it is important to know what to look for when choosing additional light sources. Consider how The lamp must meet the following requirements:
- for full growth, it is better to choose devices that emit red or blue;
- the main purpose of the source of additional light should be lighting, and not overdrying 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 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 a surface that is illuminated, and thus feeling the heat.
Will any or types of lamps be suitable for lighting seedlings
Today the market is saturated with 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, it is enough to stick foil or ordinary 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 a few ordinary lamps over the seedlings. However, common appliances do not have the necessary color spectrum for full illumination of plants.
Consuming a fairly large amount of electricity, they convert only 5% of the light, and the rest is converted into heat. As a result, plants do not receive lighting, but additional heat and, as a result, overdrying or burns on the leaves are obtained. Consequently, the use of incandescent lamps is not as efficient as others that are gaining popularity today.
fluorescent
one of best options to obtain ultraviolet radiation, which is so necessary for plants. Due to this effect, intensive growth of seedlings of saturated color will occur. In whom, this color leads to a decrease in the level of pathogenic microbes.An additional advantage of using it is 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 amount waves in the red part of the spectrum.
Also they do not have big power, and hence quick results cannot be obtained 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 watts.
sodium
Sodium lamps are considered the brightest compared to others. The spectrum of their radiation optimally helps the growth of plants. They are divided into two types: low and high pressure. It is the latter that are used to supplement the illumination of seedlings at home and accelerate the ripening of fruits.
Some representatives of this group have a mirror reflector that allows you to illuminate a large area, which saves cash. The downsides of using it are strong heat and unsafe use, since the production uses mercury with a mixture of sodium.
These lamps must not be turned on if voltage fluctuations greater than 10% are present. Temperature drop environment leads to a decrease in the efficiency of such lamps. The power of the lamp should be no more than 100 watts.
Important! Fixtures with sodium lamps it is strictly forbidden to plug into simple sockets. For them, you need to use special equipment, chokes and pulse ignition devices.
LED
LED seedling lamps are gaining popularity among farmers. Use of similar lighting on seedlings leads to the following results:
- reduction in electricity consumption;
- due to minimal heating, the lamp can be placed almost near plants;
- the lamp contains diodes of different colors, which allow you to get red and blue colors at the same time;
- high operational safety minimizes possible losses;
- lack of drying and excessive thermal humidity;
- no minimum infrared radiation.
Phytolamps
Phytolamps are complex devices, their price directly depends on specifications: power, brightness, dimensions, angle and area of illumination, case heating 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 consider all of the above characteristics.
Not a single one will survive without bright light living plant. If we talk about seedlings and seeds, then additional lighting at home can work real miracles. The lack of sunlight in the winter and spring seasons is detrimental to plants. Young stems will, with all their strength, reach for the sun, which is fraught with their thinning. Lack of light can also cause "black legs" or even death of seedlings.
Of great importance is, with the help of which lamps additional lighting of plants is provided. An overly bright lamp will burn them out, and ordinary incandescent lamps consume a huge amount of electricity.
Some seeds need to be planted already in the last weeks of January. This season in our latitudes is characterized by the minimum amount sunny days, which pushes gardeners to install additional illumination of vegetation at home. It takes a little effort and time, but the result will be colossal.
Benefits of backlighting:
- An increase in the duration of daylight hours, which is necessary for early distillation.
- Ensuring uniform illumination of vegetation, which prevents strong stem elongation and the appearance of various pathologies.
- The correct spectrum guarantees seedlings the full formation of young and fragile stems to adult strong crops.
- Illuminated plants are hardy, not exposed to infections and dangerous microorganisms.
- The crop obtained from one stem grows.
Convinced of the need to install a backlight, 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 desired effect. The backlight should resemble the natural spectrum of sunlight as much as possible.
The spectral layout of light has the following effects on plants:
- Red spectrum. Promotes the growth and development of the root system. Fruits begin to actively form and ripen.
- Blue-violet spectrum. Inhibits too rapid growth of the stem on cellular level. Stimulates stem cell division. As a result, the plant does not stretch, does not deteriorate and does not become thinner.
- 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 necessary spectrum 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 backlight with your own hands, 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 is to develop mounting methods for lamps. It can be hooks or small "ears". The main thing in this business is convenience and reliability. final stage an electrical cord from the network or generator will follow. When all the preparations are done, it's time to tackle the lamps.
For illumination, lamps can be used: DNaZ, LEDs and metal halide. These light bulbs are often used to provide plants with additional lighting in greenhouses. large sizes. For home use, it is better to purchase LED, fluorescent or phytolamps.
Read more about the types of lamps that are suitable for indoor seedling lighting:
- Phytolamps. Ideal Solution to illuminate the stems. The pink-violet spectrum is dangerous for the human body, so special reflectors must be installed with these lamps.
- High pressure sodium lamps. Give the seedlings a uniform warm light. Require the installation of special power regulators. The price of products can hit your pocket hard.
- LED light bulbs. Available to every gardener, economical and have a lot of advantages over their counterparts.
- Fluorescent lamps. They are poor in the red spectrum, therefore, among those listed, they occupy the last line in the list. Use them only when absolutely necessary.
For an ordinary gardener in an apartment, it is best to install the backlight with LED bulbs. This option is the most economical, safe, efficient and easy to implement. What are the other advantages of this type of lamps, and how to build a 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 a lot of positive aspects. For example, when making a lamp at home, you can combine two effective spectra. It turns out almost the perfect light bulb for plants.
- LEDs can be found in any building or hardware supermarket. In addition, their price is quite affordable. If the lamp burns out, replacing it will not become an unbearable burden for the average gardener in our country. The cost of the LED pays off very quickly.
- Working diode lamps will not be reflected in any way on the bill for the consumed electricity. At the same time, the amount of light they provide to vegetation is in no way inferior to other types of lamps. For the harmonious growth of seedlings, about six thousand lux are required. Diodes quietly give out this indicator.
- Last on our list, but not least for the average gardener, is ease of installation and ease of use.
How to make a DIY LED grow light
Making a simple ribbon lamp is quite simple. To do this, you need the 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 in a hardware store);
- LEDs are blue and red.
In order for the red and blue spectrum to evenly affect the plant, distribute it on the base in the following order: two red, one blue, and so on.
The elements are connected by soldering, output to the power supply, plug and switch. The tape is fixed to the prepared surface with the help of bolts, rivets. Perfectly holds the construction of double tape. The last step is to assemble a single circuit with a block, wire, switch and plug.

Phytolamps for additional illumination of plants at home
Outwardly, phytolamps resemble LED ones. Their main difference is the spectrum of the produced glow, 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's important to follow the rules.
- Be sure to observe the frequency of highlighting: day and night. A sharp change or shift in the schedule is fraught with poor development and complete death of vegetation.
- The gap between the light bulb and the plant follows an inverse quadrant law. This means that if you remove the lamp to a distance four times smaller, the intensity of the light received by the vegetation will decrease by a factor of sixteen.
- If it is possible to arrange vegetation near windows facing south, this will increase the efficiency of supplementary lighting. In addition, it will save on electricity.
- Study the lighting regimen 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 love to be in the shade. most time.
- Take 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 a must.
It is important to remember that natural Sun rays no light bulb will replace it.
