Ordinary plant lamp. Artificial light fluorescent lamps for plant growth and flowering

What lamps can not be used when growing seedlings?

• they strongly heat the air around, which can damage the sprouts,
• dry the air
• low light output - about 10-15 Lm / W,
• no incandescent lamps of blue color required for seedlings.

There are mirror incandescent lamps for plants, such as OSRAM Concentra Spot Natura. Their glass is made with an admixture of neodymium, which absorbs a certain part of the light spectrum (yellow-green), thereby contributing to the photosynthesis of illuminated plants. But still, the efficiency of such lamps is less than that of fluorescent and LED. They are more suitable for spot lighting of 2-3 plants, such as orchids.

It is strictly forbidden to turn on next to plants quartz lamps, including medical household devices "Sun" or lamps that are used in the solarium. One minute is enough for the plants to get severe burns, and not only the seedlings that were purposefully illuminated will die, but also all the house plants in the same room.

What is the difference between "illuminate" and "illuminate"?

If you grow seedlings not on the windowsill, but on special racks or in greenhouses, then the plants need to be “lit” and not “lighted up”. This means that the lighting must be on from morning to evening, from 7 am to 10 pm.

For seedlings grown on the windowsill, additional lighting is needed during the hours when there is no sun.

Rice. 3 photos cvetiksemicvetik: “In my opinion, the distance from the lamp to the plants turned out to be too big. I read somewhere that it should be 25-30 cm. But how to tie the rope again, simpler boxes put some under the seedlings.

What is the difference between ordinary lamps and special phytolamps?

Plants need a wide spectrum of light, containing both red and blue areas. Therefore, lamps for growing plants are produced with a special coating of the bulb. The light output of phytolamps is higher than that of conventional ones, however, the price is also. On the Leroy Merlin website, you can see the current prices, for example, for the most popular phytolamps - fluorescent Osram Fluora 60 cm and 120 cm long (shine with pink light).
The red spectrum is necessary for plants to build up a powerful root system, for more lush flowering and good fruit formation. Blue - for building green mass. Therefore, if your lamp does not have a blue spectrum (for example, an incandescent lamp is used), then the seedlings will stretch.

Is it possible to use household lamps instead of biolamps?

Yes, you can. The main thing is that they are not quartz or incandescent lamps, and do not shine with an excessive thermal effect.
Simmama's experience confirms this:
Michalich:“I have “Flora” on two shelves on my rack, and ordinary lumki on two. Seedlings with "Flora" are slightly larger than with conventional fluorescent lamps. But everywhere everything is growing normally.”
MNBer: "A significant difference in the illumination" Flora "and ordinary lamp I have not noticed. Perhaps this difference is noticeable when professionally growing seedlings and highlighting for a certain time. For ordinary gardeners (for me), ordinary lamps are quite suitable. I have two sets of lights. Now (in early January) one is already working to illuminate the cuttings of chrysanthemums in the morning and in the evening for 1-2 hours. When tomatoes and other one-year-olds go, more light will be needed, and longer. ”

Rice. 4 photos MNBer with two types of lamps.

Mama Lanya: “Two lamps together, in parallel - this is hanging on my window. One lamp - "Flora", the second Osram 36W / 765 (cold white light) ... Separately, I do not use "Flora", only paired with a white glow lamp. I don’t see much effect from her alone.”

Daylight lamps

They are called fluorescent lamps. They are suitable for growing seedlings by non-professional vegetable growers.

Advantages:

• luminous efficiency - 40-50 Lm / W, that is, the efficiency is quite high,
• does not heat up and does not dry the air near the plants,
• large life time,
• cold light, which is necessary especially at an early stage of growth, so that the seedlings do not stretch.

Disadvantages:

• Lamps with a choke with an unreliable starter flicker and make some noise, and also give a few flashes before starting, which reduces the life of the device, but electronic ballasts can be used instead of them - an electronic ballast.
• Do not use at temperatures below +15 +20 degrees. Therefore, when hardening seedlings on a loggia, one must carefully monitor the air temperature.
• There is no red spectrum. It can, in extreme cases, be used together with an incandescent lamp, but it is better with a Flora lamp or (which is most economical and good for plants) with warm glow fluorescent lamps.

It is better to use more powerful lamps - from 18 to 36 watts. The longer the length, the more powerful the lamp. As for the type of light - cold or warm, Mama Lanya writes: “I have Osram 18W / 765 and 18W / 840. These are lamps 60 cm long. If you take a long one (1.2 m), then it will be 36W / 765 or 36W / 840. 765s - with cold white light, 840s - with warm yellowish. I read that at the first stage the seedlings need white light (to grow the root), and at the second stage they need warm yellow - for the green mass. But I don’t strictly observe where I put it, they grow there. I personally (and my seedlings, of course) like the 765s better, perhaps because they seem to have brighter light.

Rice. 5 photos Mama Lanya, Osram 18W/865 60 cm (daylight white).

Mama Lanya shares his experience of growing seedlings at the first stage in the bathroom: “I really like the following: there are no drafts in the bathroom. It's always warm and humid there. There are no scorching sun rays, no batteries. The light of the lamp does not bother anyone. That is, some pluses, and almost no minuses (minuses are electricity and tightness). The lamp turns on and off by itself, according to the timer - from 6:30 to 00:00. It hangs about 5-8 cm from the seedlings. If you need to raise some plants (they can also be different heights) - I put all sorts of boxes and bowls. In general, the lamp hangs on a cord, and the height is easy to adjust. Well, now it's been 2 days since all the seedlings moved to new house(greenhouse with shelves, standing in the room).

Rice. 6 photos Mama Lanya.

It is more profitable to use long lamps, 120 cm each, than 60 cm, since they have more power and total light output. Instead of 4 lamps 60 cm long, 18 W each, it is better to hang 2 long lamps 120 cm each, 36 W. The height varies from 15 cm to 50 cm above the tops of the plants, depending on their photophilous nature. And, of course, it is necessary to mount the lamps for the entire length of the window sill, and not just in the middle.

Calculation of the number of lamps

It is believed that plants need an illumination of about 8000 lux. We consider the area of ​​\u200b\u200bour window sill (or shelving shelf). For example, it is equal to 30 cm x 150 cm = 4500 sq. cm = 0.45 sq.m.
Now we multiply 8000 lx by the area of ​​\u200b\u200bthe window sill, we get that we need 3600 lm. We take into account approximately 30% of the losses from hanging the lamp at a certain height above the plants, we find that we need to provide about 4600 lm. When buying, we look at the luminous flux that the lamp gives, this indicator is indicated on the label in lumens. It turns out that with a lamp luminous flux of 2350 lm, we need to buy two lamps 1200 mm long. This is if the lamp is an ordinary fluorescent lamp, with a power of 36 watts.

Phytolamps have a lower luminous flux, about 1400 Lm, so they will need at least three pieces. Considering the price of phytolamps, it is unprofitable to install them. Calculation of the number of phytolamps from dosya: “I have a fluorescent lamp L-36/77 OSRAM FLUORA. There are two such bulbs in one lamp. And above each shelf hang two lamps. That is, four L-36/77 OSRAM FLUORA bulbs shine on a shelf measuring 1 meter by 0.8 meters.”

LED bulbs

Among the LEDs, there are also those specially adapted for plants, for example, Uniel (18 W) IP40. True, the price for them is higher than for fluorescent phytolamps, about one and a half times.
Ordinary LED lamps can also be used for illumination. Their luminous flux is decent, it reaches 2000-3400 Lm. On the dimensions of our window sill 0.45 sq. m you will need two LWL-3017 2x14 W lamps, each of them has two LEDs. True, they are expensive.
Summer residents from the Sibmum forums do not use LED lighting very actively. Lenochka73 writes: “I saw that LED lamps are used as phyto. But recently I watched a program in the Udachny program, there is a section, a woman is leading - I don’t remember her name, but she is very literate, she said that LEDs have a very narrow spectrum, which each plant has its own, and get into the right range for each plants are very difficult. But in general people use it. A friend of mine grew strawberries from seeds under LED lamps last year.”

Rice. 9 photos of eustoma from ceilingman: “For supplementary lighting, I adapted an LED module - a semi-finished product for LED panels, with a power of 25 watts. We turn it on at dusk and before the end of the day, and in the morning (who got up earlier) until the onset of daylight hours.

Antalvi used LED spotlights for a small amount of seedlings.

Instructions for collecting fluorescent lamps

Valuable information about self assembly fluorescent lamps shared MNBer: “Girls, I have two lights working: one on the floor, the second on the window. Of the 4 lamps, one is "Flora". The cost of a conventional backlight is about 450 rubles. Reflectors - mirrors from a scoop sideboard (you can use any foil material). These are two ordinary lamps of a warm spectrum (there are also blue cold ones, they are not suitable) 36 W 120 cm long + choke (Feron EB53 electronic ballast 2x36). This is such a thing with long wires 1.2 m. There is an "Epra", it is cheaper. At the ends of the socket-type wires, which are very easily connected to the lamps (the pins on the lamps are inserted into the holes on the sockets) + wire with a plug + electrical tape. A wire with a plug is connected to the chokes by twisting, insulated with electrical tape and inserted into a regular outlet.
I assembled this entire structure myself (and I am a granny, I am 60 years old), without the help of men, I do not involve my son-in-law in gardening. If there is a man in the house, it will take him a couple of minutes to build it. The Flora lamp seems to be better (but, to be honest, I didn’t notice that plants are better under Flora), but the price of one lamp is more than 300 rubles.”

Lamps for seedlings - how to solve the problem of choice and what is better to buy?

In order for the plant to bloom profusely, develop well, it needs a sufficient amount of sunlight. This is needed for natural process photosynthesis - in the plant there is a synthesis of carbohydrates, which are involved in the process of their growth and development. AT summer period the time when house plants receive required amount sunlight, question additional lighting does not occur. However, with the onset of winter, this problem becomes more urgent.

Beginning flower growers, as a rule, highlight home plants with ordinary lamps. But it's completely useless. The leaves are still pale, the plants are few and poorly blooming. After all, it is not able to fully replace the color of the sun. In addition, if you highlight the plants through a conventional lamp. In this case, special luminescent

What lighting to choose

During the period early spring, late autumn and winter, when ornamental plants do not have enough sunlight, electric lighting comes to the rescue. Under the influence of their leaves become brighter and greener. And magnificent abundant flowering lasts much longer.

There are various plant lamps, how to choose the most suitable one?

For a successful year-round cultivation it is necessary to purchase a lighting installation from a specialized store. Their choice is quite extensive. To date, manufacturers offer a variety of lamp-lamps: standing on tripods, wall-mounted, hanging, attached with Velcro and clothespins.

Orange-red and blue-violet rays are considered the most optimal for them. The former promote development. The latter enhance vegetative growth. When choosing fluorescent lamps for plants, it is important to take into account the fact that the blue light energy emitted by the lamp should be a couple of times lower than the red light energy.

It is important to remember that highlighting should be done regularly, and not from time to time. Since periodic lighting can only harm plants, their biorhythms are thus confused.

When choosing a type of lighting for plants, it is important to remember that great importance has not only its intensity, but the emission spectrum. In this case the best option is a spectrum ranging from ultraviolet rays to infrared rays.

Light similar to daylight is given by artificial light sources, but not in the entire spectrum. Everyone knows that chlorophyll is involved in the transformation of light energy into the energy of organic compounds, the best light absorber is the red and blue parts of the spectrum. The plant growth lamp with a red spectrum favors the acceleration of seed germination and the growth of shoots. The growth of green mass at the first stage of plant development is facilitated by blue-violet light.

For plants as light sources, you can use different kinds lamps: incandescent, gas-discharge, light-emitting diodes, and also luminescent lamps for plants. Currently, the latter option is the most popular.

Standard incandescent lamps are the least suitable for these purposes, since they are characterized by low light intensity, orange, red predominate in their spectrum, and which accelerate vertical growth, plants stretch under such lighting.

To the spectrum daylight the closest fluorescent lamps for plants, in addition, unlike incandescent lamps, they are much more economical. Most of the plants develop well under these lamps.

Fluorescent lamps

Their light is as close as possible to natural light, in addition, they practically do not radiate heat. Most importantly, fluorescent lamps for indoor plants, unlike incandescent lamps, consume 4 times less energy.

Today in stores you can see huge selection data lighting fixtures- different power, shape, type of radiation of light waves, type of generated discharge, etc.

It is also worth highlighting energy-saving fluorescent lamps - the most popular and economical.

Distance to plants

Fluorescent lamps must be placed away from decorative deciduous plants at a distance of 30-60 cm, from decorative flowering ones - 20-30 cm. However, if you use this type of lighting as the main one - in chandeliers or sconces, then in this case main principle- not the distance to the lamp, but the sufficiency of light. But if you have large area there are 1-2 devices, then the plants should be placed as close as possible to the lamps, that is, at the distance indicated above.

When the plant is located on one side of the lamp, it is recommended to periodically turn it over.

Characteristics

As a rule, fluorescent lamps are used for growing plants of the LBT or LB day type, since they give cold light. Brands such as LDC and LD are unsuitable for such purposes, since their spectrum can only depress the plant.

Depending on the distance and area of ​​​​the illuminated room, the power of the lamp for indoor plants is selected.

How to properly place a plant lighting lamp

In the process of placement, it is important to remember that if you double the distance to the lamp, then you need to quadruple the intensity of lighting on the plant.

If burn marks begin to appear on the leaves, then the light source is too low, pale leaves and elongated stems indicate that the plant growth lamp is too far away.

Lateral artificial lighting able to bend the stems towards the light, so it is better to highlight from above.

Lighting duration

Since the primary goal is to increase the daylight hours of the plant, then it is necessary to extend it, depending on the natural daylight hours - in the evening and in the morning for 3-4 hours. As a result, the time should be about 6-8 hours. On particularly cloudy days, it is advisable to turn on the lamps for 12 hours.

It is also worth noting that plants require a dormant period, since forced long flowering in winter period depletes them significantly. The exception is plants that bloom in winter.

In order for the plant to develop well, bloom profusely, it needs to receive a sufficient amount of sunlight. This is necessary for the natural process of photosynthesis, when plants synthesize carbohydrates involved in the process of their development and growth. In the summer, when home plants receive a sufficient amount of sunlight, the question of an additional source of lighting is not worth it. But with the onset of winter, the problem becomes urgent.

Many, especially beginner flower growers, try to highlight their green pets with ordinary lamps. But it hardly helps. The leaves remain pale, the stems are thin, the plants bloom poorly and little. And this is understandable, because artificial lighting cannot completely replace sunlight. Especially if you illuminate the plants with ordinary lamps.

They need special lamps. We will talk with you today about which lamps are best for plants to grow all year round. But before choosing a lamp, let's find out what kind of lighting is needed for plants in winter:

What kind of lighting do plants need?

During late autumn, winter and in early spring, when ornamental plants do not receive enough sunlight, electric lighting comes to the rescue. With the help of additional light, their foliage becomes greener, brighter. And plentiful lush bloom lasts longer.

To successfully grow plants all year round, you need to purchase a special lighting installation in a specialized store. Their choice is quite wide. Trade offers a variety of lamps-lamps (pendant, wall, standing on tripods, attached with clothespins and Velcro).

But you need to know that you need to illuminate not from time to time, but regularly. If you turn on the lighting periodically, then you can only harm the plants, as their biorhythms go astray.

The blue-violet and orange-red rays are considered the most useful for them. The former contribute to increased vegetative growth. The second accelerate their development. When choosing a lamp, take into account the fact that the red light energy emitted by the lamp should be a couple of times greater than the blue light emission energy.

Install the lamp from above so that the light from it covers the entire area on which there are home green spaces. But at the same time, make sure that the lamps do not block the leaves from the source of natural light. If there is no other way out, you can place the lamps on the side, but then place them exactly on both sides. Keep in mind that plants are drawn to the light source and therefore may grow unevenly with one-sided lighting.

What lights are best for plants?

Before choosing a lamp, remember that all these devices have their advantages and disadvantages. Let's take a look at them briefly:

Fluorescent lamps are excellent sources of artificial light. Well, evenly illuminate the entire surface, do not get very hot (40-45 ° C). Therefore, they can be placed in close proximity to flower pots.

Fluorescent lamps have a spectrum with a predominance of blue. Therefore, they are best used in combination with incandescent lamps.

Some flower growers buy aquarium lamps for illumination. But I want to warn you right away that there will be no sense from them, since they are not suitable for potted plants.

Incandescent lamps are best used together with fluorescent ones, since they do not have a blue-violet component in their spectrum (unlike fluorescent ones).

The most suitable for green spaces are special phyto-lamps. They have the most suitable emission spectrum for them - a maximum of blue and red. Although the light output of phyto-lamps is slightly lower than that of white and daylight lamps.

What to choose in the store?

Phyto-lamps Paulmann © (power 40, 60 and 100 W). They are very convenient to use, as they have a base of the usual size and are screwed into an ordinary cartridge. Their glass is covered with a special layer that prevents the leaves of plants from overheating.

Flora-Glo luminescent phytolamps manufactured by Hagen. They glow with a soft, delicate pink light. Just two of these lamps are enough to provide necessary lighting plants and grow them all year round.

If the necessary phyto-lamps are not on sale, you can use ordinary lamps sold in stores, namely:

Discharge lamps that have a high, intense luminous flux. Due to the mixtures of gases that fill the flask, there is a variation in color and radiation flux. From their diversity, for better growth, development all year round, choose fluorescent, mercury. Suitable metal halide, high pressure sodium lamps.

Fluorescent lamps can also be used in the absence of a phyto-lamp. They are inexpensive, and they can be used for other household purposes. But they have a very small luminous flux, a lack of the necessary spectrum, and it is not enough for photosynthesis. Therefore, it will be better for the development of plants if several of these lamps are used for lighting at once. Good luck, dear flower growers!

The basis of highlighting is the change of periods: day and night. Schedule immediately build a clear, without a sharp change in the length of lighting, otherwise it will negatively affect the growth of plants.

Very carefully you need to choose the distance between the light source and the seedlings. The radiation power operates on the basis of the inverse square law. Therefore, to increase the intensity of light by 4 times, you need to move the lamp to a distance less than 2 times. To save energy and increase efficiency, it is better to place seedlings in the area of ​​\u200b\u200bthe southern windows.

Every plant needs an appropriate regimen. For example, vegetable seedlings need natural light, other plants choose partial shade. If the windows of your apartment face the north side, then your seedlings will need additional lighting.

There is a very simple way to improve lighting. You just need to use reflective screens (foil roll, mirrors, pure white cardboard), covering the boxes with seedlings with them. inside premises.

Remember that the sun's rays will never replace artificial light. Therefore, if possible, it is better to refuse winter cultivation. The ideal time for the growth of young shoots is the period from March to April.

What are the lamps for growing seedlings

So, why can't plants be illuminated with an ordinary lamp? Because it has an incomplete set of spectrum, and seedlings need full coverage.

For example, the blue spectrum is needed to restrain the growth of the stem and stimulate timely cell division (blocks excessive stretching of the plant), and the red spectrum activates the growth and formation of roots. The entire set of spectra has a positive effect on the full development and size of the young.

That is why special lamps were developed for lovers to grow seedlings with their own hands. Such lamps have the following varieties:

• Phytolamps. They have a pink-violet spectrum, which is ideal for plants, but very harmful to human health. Such lamps must be equipped with special reflectors.
• Sodium metal halide. They have their minus - too little blue. In this regard, the full development of plants is inhibited, and they hatch with great difficulty. In addition, these lamps necessarily require an additional device-power regulator.
• Luminescent. Fairly affordable and quite effective. Minus - too cold light gives too poor a red spectrum.
• Classic (incandescent). More suitable for heating a room than for lighting. The most economical option.
• LED. Great for backlighting. As an additional plus, you can call a long service life.

The cost of lamps depends on their type, configuration, manufacturer. average cost lamps ranges from 900 to 2,500 rubles.

sodium

Sodium lamps are best used to illuminate seedlings in the last stages of cultivation. The light of these lamps has a positive effect on the process of flowering and the formation of ovaries. But at the time of plant growth, it can accelerate the stretching of the stems.

Attention! Such lamps should never be directly connected to the socket. They require special equipment.

Advantages:

• Increased intensification of radiation, which has a beneficial effect on photosynthesis;
• luminous flux stability;
• duration of service life;
• yellow-orange glow that does not cause irritation of the eye membrane. This factor allows the use of these lamps even in residential areas.

Disadvantages:

• high price;
• the need for an additional regulatory mechanism.

Phytolamp

The spectrum of colors of these lamps allows housewives to grow beautiful and strong seedlings. Phytolamps are often used in greenhouses and greenhouses.

Advantages:

• profitability;
• efficiency;
• compactness;
• durability;
• environmental friendliness;
• security.

Disadvantages:

The pink-lilac glow that these types of lamps emit is unnatural for human eyes, and therefore sometimes causes headaches. Use in residential areas is only permitted with the installation of a mirrored external reflector.

Metal halide sodium lamps

These artificial light sources need additional devices to fully work. This fact significantly increases their cost.

The advantage is increased efficiency, and the disadvantage is a slight deficit in the blue spectrum.

Fluorescent lamps

Fluorescent lamps have a full spectrum, which is of particular value for improved growth and full development of plants. When buying, ask the seller for the conditions for connecting the lamp. Some of them can be turned on directly, and some require a ballast (additional device). Of the advantages, only cold light can be called.

The disadvantages are as follows:

• low power (you need to install several at once);
• low red light component when emitted;
• fragility.

classic lamps

Some owners are trying to save money, so they illuminate the seedlings with ordinary incandescent lamps (with a tungsten filament). Such a process is not only inefficient, but also basically useless.

There are reasons for this, contained in the features of these lamps, namely:

1. Only five percent of energy from all radiation, turns into a luminous flux. The rest, ninety-five percent, is converted into a thermal component. That is, such light sources heat the room better than illuminate.
2. The radiation spectrum does not meet the needs of seedlings, so it has a detrimental effect. Under such conditions, the stem is excessively stretched in the sprouts, the biomass dries up, and the leaves get burnt.

LED

To date, LED lamps for growing seedlings are considered the most optimal and balanced choice.

Ideal illumination is carried out due to the following factors:

• Low power consumption. The lamp itself does not overheat, so you can safely place it as close to the seedlings as you like. This will not be detrimental to your plants.
• Thrift.
• Durability.
• LEDs do not overheat the soil. This means that the frequency of watering can be significantly reduced, because the earth will not dry out for quite a long time.
• The ability to get a purple color, which, although not useful to human eyes, is excellent for sprouts. LED lights you need to select, taking into account at what stage of development your plant is. For earlier steps, a large number of it is blue, and less reddish. If you mix these shades, you get the desired purple.

How to make a lamp with your own hands - step by step instructions

Modern shops and garden centers will offer you an incredible amount various lamps for growing seedlings that guarantee the right spectrum, the necessary duration and intensity of lighting. But with a little imagination and a little physical effort, you can easily make such a lamp yourself.

To create the simplest design, you will need a couple of wooden blocks and a few fluorescent lamps. So, step by step instructions:

• Take four wooden bars, the length of four of them should be one hundred centimeters and one - 80 cm.
• Prepare screws: short and long.
• Attach the fluorescent lamps ( right amount) on a piece of wood, eighty centimeters long.
• Then, connect two wooden blocks, in the form of the letter "L". With the other two, do the same. For fasteners, you can use screws or ordinary PVA glue.
• Install on top, between the two "L", a beam with a lamp, and carefully fix it.
• As a result, you should get a hut. It is under it that your seedlings are established.

Of course, as lighting, you can choose absolutely any design. Remember that by growing the plants yourself, you will be completely sure that they are free of various chemicals and pests.

An additional plus is that the built lighting mechanism can be used repeatedly. That is, collect seeds from the harvest in a timely manner in the fall, and grow healthy and strong seedlings in the spring.

Outcome

Vegetable and flower sprouts are heat-loving plants, so their formation directly depends on the length of daylight hours. Under low light conditions, the process of photosynthesis begins to slow down, the growth of biomass is inhibited, and the seedlings begin to get sick.

Therefore, if you want to get healthy and strong seedlings, provide the young growth with proper and high-quality lighting. Remember that you have to make an effort if you want to enjoy the aromas of flowers and the taste of vegetables collected from your garden in the summer.
