Even from school, everyone knows that plants need sunlight. Thanks to the sun, they grow, bloom, bear fruit, produce oxygen, absorbing carbon dioxide through photosynthesis. However, when growing a plant in home or greenhouse conditions, it can suffer due to a lack of sunlight - after all, windows cannot move after the sun. And if they are located on the north side of the room, then this is even worse, since the sun does not look there at all.
The plant becomes sluggish, its growth stops, more abundant watering does not bring the desired result. What to do in this case? There is a solution: the installation of special energy-saving lamps that will extend the daylight hours for your green favorites.
Features of energy-saving lamps
What makes ESL lamps attractive? Consider their main features.
- They have a wide assortment list.
- You can choose the necessary type of lamp depending on the stage of development of the plant (growth, flowering, fruiting).
- They are economical when consuming electricity, and their operating period is quite long.
- No heating during operation.
- For a more convenient choice, they are marked accordingly: during the growth period, it is best to buy lamps marked with the numbers 4200–6400K, and during fruiting period - 2500K or 2700K. The power of the lamps can be 150 or 250 watts.
Phytolamps have several subspecies, in each of which there are devices of varying degrees of power and type of radiation. Let's get to know them better.
- LEDs ESLs of this type are currently in high demand, because they can be used to create lighting that is very close to ideal. They are suitable for both home and greenhouse use. In the line of LED lamps there are varieties with different emission spectra, which means that you can purchase ESL suitable for the stage of development at which your plant is located. Advantages of LEDs: they do not heat up, consume a minimum of electricity, have a long service life. And you can combine in one device lamps of several colors, which will allow you to illuminate several flower pots or beds at the same time.
- Luminescent ESL. This variety is good for growing seedlings, because it has a blue spectrum, which is necessary for photosynthesis.
Choose lamps with a marking of at least 4,500 units, as it is optimal for the formation of plants.
Pluses of fluorescent lamps: economical, give bright lighting, do not heat up. You can choose a longer or shorter lamp. The lighting area depends on the length - the larger it is, the wider the grip.
- Compact fluorescent tubes. Also used to extend daylight hours in greenhouses or living quarters. In the line of these devices there are lamps that are suitable for each of the stages of plant development. For example, for recently sprouted sprouts, you can choose CFLs with markings from 4200K to 6400K, and during active growth, CFLs from 2500K to 2700K are suitable. And for daily use, buy lamps marked 4500K, since it is their light that most resembles sunlight. The advantages of compact fluorescent lamps: low power, but at the same time a high degree of brightness, there is a built-in relay to start the on / off mechanism. They also have a large assortment of devices in this segment, they do not heat up and serve for a long time (about 20 thousand hours).
- Gas discharge. This group of products is not all intended for lighting plants. You can only buy lamps based on sodium, mercury and metal iodides (metal halide). Sodium bulbs are optimal for adult representatives of the home flora, metal halide lamps are for use only in greenhouse premises, since they should be at least 4 meters from the foliage. Mercury lamps are not very popular because of the content of a hazardous substance in them.
To select the optimal variety of energy-saving lighting, it is important to remember that different color spectra of light are needed for different stages of planting development.
When a seedling pecks and grows, it needs blue light. During flowering and fruiting to strengthen the root system and accelerate the ripening of fruits - red. So be sure to consider this when purchasing ESL.
- Look at the markings. The unit of measurement of luminous flux is lumen (lm), respectively, the higher this indicator is, the brighter the light will shine. Focus on the fact that for high-quality lighting per square meter of area you will need 8,000 Lux, a type of lamp DNAT 600 W.
- Consider the proper distribution of lighting devices throughout the room, taking into account the location of your plantings. For example, if you put lights on the sides of flower pots, the plants will stretch in their direction and eventually twist.
To expand the pots is not a good idea, it is best to simply install the lamps so that the light falls from above, then the seedlings will become “slimmer" and will be able to stretch to the full height.
To organize artificial lighting for plants using ESL, you should not only correctly choose a lamp, but also learn how to use it. There are some tips on how to do this.
- In periods when the sun does not spoil its presence too much (the period from mid-autumn to mid-spring), lighting devices must be turned on twice a day: for 2 hours in the morning, and another 2 hours in the evening. In September and October, as well as in April - May, these periods of morning and evening lighting are reduced to an hour.
No need to keep the light on all day and night - in nature there are no places where the sun would shine without interruption, and therefore, at home, plants should “sleep”.
- It is forbidden to install light emitters close to seedlings. The minimum allowable distance is 20 centimeters. And although the ESL does not heat up, too close a location can damage the sheet by drying it. If your plantings are located in such a way that the lighting devices are not far from their surface, choose low-power bulbs.
- In total, the daylight hours of the plant at home should be at least 12 hours in a row.
