Lamps accelerate photosynthesis processes in plant leaves, promoting growth and development

When choosing a reliable, high-quality phytolamp, one proceeds from the goals that need to be achieved. For growing seedlings, a home greenhouse or a winter garden, powerful models with full or multispectrum LEDs, a wide beam angle and bright light are suitable.

For artificial supplementary lighting, the indicators of photosynthetic flow and illumination level are important - the higher they are, the faster the growth and development of plants occurs due to the processes of photosynthesis.

For several pots with indoor plants, a low-power narrow beam with a radiation spectrum - universal bicolor (red and blue) is sufficient. A balanced solution is an LED light bulb with an E27 base, which is screwed into a stationary base from a regular table lamp.

Illumination of seedlings - LED phytolamps for plants. Review. Which one to choose?

TOP 10 Best phytolamps for growing seedlings and indoor plants: choosing which one is better? | Rating + Reviews

Description of 2 and multi-color LED phytolamps

A phytolight is a lamp designed to illuminate plants when there is little or no natural light. It can be monochrome, 2 or multi-color, with the addition of white and ultraviolet.

Look in the picture at the spectrum of light needed by plants. During different periods of growth, plants need light of different colors. The most commonly used are red and blue, and in more expensive models white and ultraviolet. Phytolamps provide lighting with the required spectral composition and brightness.

These lamps use LEDs of different colors as a light source. The color ratio is adjusted by reducing the brightness or turning off unnecessary light sources.

Power is supplied from a ~220V network or an external power source =12V.

If necessary, such a lamp is made from scrap materials and LEDs or LED strips of the required colors - red, 630 nM, and blue, 465 nM. These values are close to the 660 and 445 nM used in factory designs.

It is allowed to use RGB strips and LEDs without connecting the green light.

Consumer Reviews

Before purchasing LED phyto-tape, many people turn to the Internet for help, carefully re-reading the reviews of those who have similar experience in plant growing. At this stage, it is important not to be disappointed in the new technique and to draw the right conclusion based on the opinions of people who have achieved success. To do this, you may have to participate in thematic forums and correspondence. An in-depth study of the issue of organizing lighting based on LED strip will allow you to avoid the mistakes listed above, which then lead to negative reviews.

Every plant grower must understand that even a slight deviation from generally accepted conditions for growing plants can have a bad effect on their development. Incorrectly organized LED lighting is no exception. Therefore, simply exposing flowers to blue and red light is not enough. At a minimum, it is necessary to control the distance from the lamp to the leaves, observe the day and night regime, and be confident in the quality of the phyto-tape used. Only a serious approach to business guarantees positive feedback in the future.

The whole truth about LED phytolamps - 3 advantages and 1 disadvantage

LED phytolamps have advantages over other types of lamps:

LEDs emit light, but, unlike other types of lamps, they do not heat up and do not warm the plants located under them;
arranged evenly above the pots or collected in panels, which prevents the flowers from tilting towards the light;
This is the most economical and durable light source.

The only drawback is the higher price, but it pays off due to energy savings and is gradually decreasing.

LED phytolamps for 2 types of aquariums – freshwater and marine

Look in the picture at the aquarium illuminated by phytolamps. There are also plants (algae) here and they are different in fresh and sea water.

In a freshwater body of water, algae require red and blue colors in a ratio of 5:1. In the sea, salt water absorbs red light, so the deeper the home of the aquarium's inhabitants, the bluer the illumination.

The inhabitants of the aquarium are better influenced by brighter light 8-10 hours a day than weak light 14-16 hours. The origin of most aquarium algae and corals is the tropics, where daylight hours last 12 hours, the period of photosynthesis is no more than 10, and long-term illumination provokes the development of lower algae.

According to the observations of Western aquarists, a decrease in illumination during the day by 1-2 hours has a positive effect on the processes occurring in plants.

The recommended average power of LED lamps is from 0.1-0.3 W/l in aquariums without algae to 0.8 W/l and higher in “Dutch” aquariums with lush vegetation.

LED phytolamps for phalaenopsis orchids – 2 types of lighting

Look in the picture at the phalaenopsis orchids illuminated by phytolights. Lamps must provide diffuse illumination, so one lamp is not enough, regardless of power. They are installed as close to the plants as possible (3-5cm). The choice of color depends on the task facing the plant owner.

Red light stimulates active flowering. To do this, it is enough to turn on the lamps for an hour twice a day, in the morning and in the evening.

Leaves grow in blue light. They should also be turned on in the morning and evening, in the dark, to extend the daylight hours of the plants.

Blue-colored lamps that produce almost no visible light are black lamps.

The best option is a combination of red and blue colors, for the growth of flowers and leaves, and white, which turns on when there is a lack of daylight.

There are two light distribution options:

red and blue lamps shine simultaneously;
A red lamp shines in the morning and evening, and a blue lamp during the day.

When there is insufficient natural light, the white light is turned on twice a day for an hour.

There was no phytolamp yet

Plants love light. Everyone knows this. If the windows of the house do not face the sunny side, then the seedlings turn out to be lethargic and grow poorly. At the same time, the neighbor, who lives in an apartment with windows on the other side, probably has taller and stronger seedlings. Unlike the one that grows on the dark side.

Sometimes it gets worse. The sun shines through some windows in the morning and through others in the afternoon. And so the pallets with seedlings wander around the rooms every day following the sun. Each transfer is a potential opportunity to drop them and break the newly hatched stems.

In spring, when it gets dark early, plants do not receive enough light and do not grow as quickly as we would like. They say that for normal development they need 12-16 hours of light a day. But where can you get them in March-April? There's not even a dozen here. That’s when the idea comes to mind to buy a philolamp and illuminate the plants with it for several hours, when the sun is already below the horizon.

While she was away, my wife moved pallets of seedlings twice a day.

Do-it-yourself phytolamp for plants - 4 stages of assembly

Look at the picture at the homemade phytolamp. If necessary, it is made by hand. Such a product will not be as beautiful as a factory-made one, but it will be much cheaper, and it will help plants grow almost as well.

For manufacturing you will need the following materials:

LEDs. In such designs, special LEDs are used for phytolamps or super-bright ones installed on the radiator. Instead, you can use a large number of low-power tapes of appropriate colors (630 and 465 nM) or RGB tapes.
Base or radiator. When using aluminum or steel strip, these elements are combined.
Power supply. This is a special driver, dimmable power supplies for each color or one unit and switches for groups of LEDs. The power should correspond to the power of the lamps and 20% reserve.
Base. It uses a plastic box or a metal structure that can serve as a radiator. The size should match the length of the bed and not blind people on the street.
Stand for fastening. It is advisable to provide height adjustment. Instead of a stand, it is allowed to hang the phyto-lamp from the ceiling.
Installation wires. Copper strands are used, which are soldered to the LEDs.

The assembly order is as follows:

Check elements for serviceability. The LEDs are checked by a tester, and the tape is checked by applying voltage.
Attach light sources to the base. High-brightness LEDs are attached with bolts and thermal paste, and the tape is secured with an adhesive layer or double-sided tape.
Connect the wires using soldering or connectors.
Attach the base to the stand and adjust the height.

Do-it-yourself phytolamp for plants

Some time has passed

Surely you are already tired of reading lengthy discussions and are waiting for an answer to the main question: to buy or not to buy?

Instead of a direct answer, I'll show you a couple of pictures. This is what your window or table on the balcony will look like, where the seedlings and phytolamp are located. If there is a separate room, then everything is fine. But staying for a long time in a room that is illuminated with such a killer purple light is not an acquired taste:

As for plant benefits, look at these two tomato plants. Surely you can guess which of them was illuminated every evening with a phytolamp, and which was in the “control group” and grew in natural light on the windowsill of another room:

Draw conclusions. I do not “promote” my purchase in any way. The purchased phytolamp, like the OBI store itself, is nothing to me. Why would I embellish something or, on the contrary, denigrate something? Here in the article are just facts.

The advantages are obvious - plants grow faster. The disadvantages are also obvious - the lilac light of the lamp begins to irritate over time. Fortunately, I have the opportunity to put all this gardening in a separate room and close the door. But using a phytolamp in a one-room apartment, in my opinion, is a dubious pleasure.

Phytolamp is a great gift for March 8

Many men are in a depressed and depressed mood on the eve of this wonderful spring holiday. What to give to your wife, mother or just a good friend on March 8th? If your women are interested in growing fruit plants, then they will certainly appreciate the gift. Prices for phytolamps vary. If you want to make one of your family members happy, you can buy a more expensive lamp. If this is just a routine offering, buy a cheaper herbal lamp. The one that screws into a regular base. In any case, such an unexpected and desirable gift for any gardener will certainly be appreciated.

As for me, that's exactly what I did. I presented my wife with a large LED phytolamp from the OBI store. However, you can buy them in other places. For example, order on Ozone.

Giving phytolamps is great! On the one hand, this is not an essential item, so the gardener himself most likely will not buy such a thing for himself. But if someone gave it... In a word, I gave you a tip, and you decide whether it’s worth doing this in your case.

Reviews of Chinese LED phytolamps for plants from Aliexpress - 3 reasons to refuse the purchase

Cheap lamps are sold in China, on Aliexpress and other trading platforms. But with the rise in the dollar exchange rate, the price/quality ratio has worsened. Besides this, there are other reasons:

The parameters do not match those specified. The lamp shines, but its brightness is checked only with a lux meter.
No warranty. Theoretically, it is, but you will have to send the goods to the seller at your own expense and wait a long time for a return.
Poor quality of LEDs, which manifests itself after a few months, when it is too late to refuse the product and demand a refund. This is due to the manufacturer’s desire to save on costs at the expense of quality.

Reviews about the seller should be treated with caution. Most shortcomings are not identified immediately, but after some time, when a positive assessment has already been given.

Installation height of phytolights

How to choose a phytolamp

The optimal values for plants are wavelengths in the blue spectrum of 420-460 nm and in the red spectrum of 630-670 nm. The spectrogram on the lamp packaging shows the peak values; when selecting a lamp, this indicator is checked first.

The choice of shape depends on how much area needs to be illuminated. For spot lighting, plinth phytolamps are suitable; for shelves and window sills, it is more effective to choose a linear phytolamp.

The type of connection depends on where the device will be installed and determines ease of use. There are mobile options - battery-powered phytolamps, and stationary ones - base lamps, ready-made lamps with standard 220 V power supply, connected via a USB adapter or switchgear.

The durability of the luminaires is determined by the presence of built-in cooling radiators. They also take into account the ease of operation and maintenance and economic factors - feasibility, price of a phytolamp for plants and energy consumption.

Top phytolamps will allow you to evaluate the advantages and disadvantages of each type.

It is also important to know 3 nuances

There are 3 nuances taken into account when choosing a phytolight:

too bright light is harmful, as is its lack, so the illumination should be checked with a lux meter or calculated based on the power of the lamps per unit area;
plants are drawn to light, so it should be located evenly above them;
the required distance to the plants is 25-40cm, so the lamp must be raised as they grow;

3 nuances taken into account when choosing a phytolight

How to avoid 3 mistakes

There are mistakes that inexperienced electricians make when choosing and installing LED phytolights:

Incorrect color ratio. Different plants at different periods of growth need light of a different spectrum and it must be changed during the growing process.
Insufficient power supply. It should exceed the power of LEDs by 20%.
Install the lamps so that when watering they get water. This will lead to a short circuit and failure of the device.

LED phyto-lamps. Are they really good for plants?

A friend of mine needs to grow a certain plant at home (hussars, keep quiet!). To do this, he asked me to order a phyto-lamp. My stories that she was unlikely to help in the difficult task of growing a capricious sprout did not convince him. I ordered a pair of LED lamps, which arrived in a little over two weeks. From all the variety in the store, I chose products with 80 LEDs, base 27, 220 V. The lamps arrived each in their own box.

The matrix is assembled on 2835 SMD LEDs, which are arranged in a circle and are not covered by anything (probably so that part of the spectrum is not absorbed).

The diameter of the substrate is 50 mm. The length of the lamp including the base is 55 mm.

30 LEDs are blue and the rest (50) are red.

How useful such lamps are for plants is written on the product page.

With an input voltage of 200 V, the lamp consumes about 0.023 A. That is. power is about 4 W. I have nothing to measure brightness with. But in the bins there was “corn” for the same 4 W with ordinary white LEDs. Assessing the illumination using a mobile lux meter, I can say that they provide approximately the same amount of light. As you can see in the photo, near the LEDs there are two contacts with the signs “+” and “-” (I tried to desolder the matrix, sloppy traces of soldering are visible.). The voltage on them turned out to be 93 V, with the same incoming 200. This, of course, is strange to bring unprotected contacts out. But the current there is so weak that when I touched it with dry fingers, I didn’t feel anything.

During operation, the LEDs heat up to 60 degrees. Of course, it’s very interesting what driver is inside. But, unfortunately, I was unable to disassemble the lamp without destroying the housing. It looks like the matrix is glued to the body. And since the lamp was purchased for a friend, I did not break it. However, apparently, no stabilizer is used in the driver. When the input voltage changed from 170 to 220 V, the voltage at the contacts also floated from 92 to 94.5 V.

Actually, there were many descriptions of similar lamps. But I went further and conducted a growing experiment to understand how effective it is. To test this, I decided to do the following: sow some grass in three separate pots. One of them should be illuminated with a phyto-lamp, the second with a lamp with conventional LEDs, and the third should be illuminated with natural light from the window. I don’t know what went wrong, but the mixture of barley and wheat sprouted in only one pot! This is despite the fact that the same soil and approximately the same amount of seeds were poured into everything. Well. I had to experiment with only one pot. I made a pipe out of cardboard so that the light from the window would not fall on the plants. There are two holes on the side for ventilation. I placed the lamp under review on top. And he began to wait).

The lights were turned on every day for about 10 hours. The result of the experiment after two weeks is in the photo below. This is the final tuft of grass.

The cat was delighted with the fresh greens.

Before this, he also enjoyed gnawing on leaves of cyperus and green onions.

All that was left after his raid.

I'm not a botanist, and perhaps my conclusions will not be very correct, but it seems to me that the lamp fulfills its functions quite well. At least the sprouts grown without access to sunlight or any other light felt great.
