What Kind Of Bulbs You Need For Sprouts | Gardeners Info

In order to grow strong and healthy seedlings, it is not enough just to water and fertilize a few times. Young plants need 12-14 hours of sunlight daily for normal growth, otherwise the seedlings start to stretch out, their stems become long and too thin.

But unfortunately in most Russian regions during the seedling growing period from the end of January to the end of March the light day is short, and in addition, cloudy weather prevails there. Therefore, seedlings should be additionally illuminated to create all conditions for normal growth and development. But to buy a lamp to light seedlings is not easy. And you need to know which bulb to choose so that your plants will get the light they need.

Why the extra light for your seedlings

Brouting the seedlings usually takes place in March, and seeds of a number of flowers have to be planted even earlier, in February.

The light day is still too short at this time, about 8 hours or less, resulting in lack of light for proper growth and development of the seedlings. And the lack of light leads to seedling wilting: the foliage becomes pale and weak, the seed may not germinate at all, or the seedlings that emerge are too weak and do not develop well.

What the light should be

Additional light will be beneficial to seedlings if it meets the following requirements:

    1. У дополнительного освещения должна быть определенная продолжительность. Different types of seedlings require a certain length of daylight hours, which should be considered when using supplemental lighting. For example, some types of flowers may bloom with 13-14 hours of light, while others only need 10 hours.

      1. Have the right intensity. Different types of seedlings require different light intensities, from weak (3,000 lux) to bright (10,000 lux).

      1. The frequency of additional lighting, since plants are also lit a certain amount of time in natural conditions, not 24/7.
      2. It is not only necessary to combine all these factors correctly, but also to combine them accordingly. Therefore, the correct change of night and day must be secured when arranging supplementary lighting. This is why light-loving plants should not be extra-lighted with weak lamps - they will get sick even if the daylight hours are long enough.

      In order for the plants to develop normally, they need a certain spectral composition of extra light. The spectrum is conventionally divided into the following types:

      1. Warm (with long waves, red and orange). The orange-colored rays are 620-595 nm, the red-colored rays are 720-600 nm. And the temperature is usually 2700-3000 K.
      2. Cold (with short waves, blue and violet colors). Their wavelength is 490-380 nm. The temperature may be 4000-6500 K.

      The two parts of the spectrum are necessary for seedling growth and development, but they may have different effects on seedlings. On bulbs designed to provide extra light for seedlings, certain numbers are placed; the higher this number, the cooler the light.

      It is best to select lamps for growing seedlings with a certain spectrum in which 1/10 part is red and the rest is blue.

      The red type of spectrum activates chlorophyll formation, also affects rapid root development, promotes better fruit and bud formation.

      The blue type of the spectrum aims to activate protein synthesis in crops as well as chlorophyll production, promotes better formation of vegetative mass, laying of new stems.

      What are the lamps for seedlings

      The main types of lamps with their advantages and disadvantages are described below.

      LED lamps

      All the criteria needed for seedling post-lighting are embodied in LED lamps that are most often used for seedling post-lighting. One of the main advantages of such devices is that they consume 3 times less electricity than conventional bulbs in chandeliers. Usually the warranty period of such devices - at least 100 & nbsp;000 hours.

      There are bicolor LED lamps, which should be used to enhance plant growth, if the room has other sources of light (in a greenhouse or in greenhouse conditions). And full-spectrum LED lamps should be used where other light sources are absent or insufficient.

      This type of lamp has many advantages over other types of lamps:
      • such devices are economical and use several times less electricity than conventional bulbs;
      • they have the best combination of spectra, blue and red, necessary for active growth and development of seedlings;
      • they contain fire protection devices so the bulbs can be left on even when the house is empty;
      • easy and easy to use;
      • long-life usage;
      • the bulbs are safe and environmentally friendly for the seedlings.

      The main drawback of such lamps according to gardeners is their high cost. However, they last a very long time, so they pay for themselves in that time and when the bulbs fail, they are simply replaced with new ones.

      Natrium

      These high pressure lamps create soft and warm red type lighting, close in saturation to the natural spectrum. This type of lamp is gas discharge, with sodium vapor burned in a special cylindrical glass tube.

      This type of lamp is used in large area rooms - greenhouses or greenhouses. For home use these lamps are unprofitable: they cost too much and do not pay back even in 5-6 years when growing seedlings at home.

      What kind of bulbs you need for sprouts | Gardeners Info

      There are several types of these lamps:

      1. DHat: these lamps are arc-shaped and provide a powerful and intense stream of light. One such light source illuminates a large area, so it is advantageous to use them in greenhouse conditions.
      2. Dna3 has a cylindrical shape, covered inside with a special layer that reflects light. But these devices are not very powerful, so they are not usually used for growing seedlings and plants.
      3. DRI or DRI3 are advanced lighting devices of the latest generation. They are very powerful, so they can provide illumination for greenhouses with a large area. These sodium lamps are safe to use and resistant to electrical fluctuations. Their lifespan is quite long, but they are difficult to repair or replace parts.

      Основными advantages of such light fixtures are as follows:

      • fixtures are economical and durable;
      • optimal spectrum;
      • high efficiency.

      The main disadvantage of sodium lamps is the excessive heat radiation. While for large-area greenhouses this phenomenon does not have much effect on soil drying, at home it is not only the soil that dries out, but also the seedlings themselves. In addition, the devices consume a sufficient amount of electricity, which is an additional expense.

      Luminescent

      Daylight lamps are most commonly used for supplemental illumination of cultivated plant seedlings grown at home. They are compact and economical since they consume little electricity, but their light is sufficient for the growth and development of seedlings.

      What kind of bulbs you need for sprouts | Gardeners Info

      There are several categories of such lighting devices:

      • Universal type, therefore not only used when growing plants, and their spectrum is different from what is needed;
      • Special type. Their surface is covered with a special coating, thanks to which the spectrum required for the development of seedlings is created;
      • compact ones. These lamps are of various sizes, so one may choose a lighting device for illumination of any room.

      But such fluorescent light negatively affects the retina, so such lighting devices are installed either in greenhouse conditions or in isolated rooms.

      What lamps are not recommended for seedling lighting

      Ordinary incandescent lamps are not used for seedling lighting because they strongly heat up and dry out the air in the room, which harms the seedlings, not too much power - not more than 15 Lm/W, and their spectrum lacks the blue tone, which is important for the growth and development of seedlings.

      Also do not include quartz lamps, including medical or those designed for tanning beds, to light the seedlings. Even 60 seconds of this lamp is enough to cause severe burns on the leaves and other parts of the seedlings. Not only seedlings are killed by these lamps but also other indoor plants in the room.

      How to make an illuminated space for seedlings with bulbs with your own hands

      You can make additional lighting for seedlings using different kinds of lamps as well as make plants illuminated without any light fittings.

      Building up illumination without lamps

      This kind of illumination is very easy to do if you have a cardboard box and foil at hand. You have to remove the top and sides of the box, leaving small rims. Such a construction should be wrapped with foil and installed behind the containers with plants. The sun's rays will fall through the glass on the foil and be reflected on the sprouts. This will illuminate the seedlings evenly on all sides.

      This type of illumination is affordable and economical and illuminates the plants effectively. However, if the number of seedlings is large or the weather is cloudy, such a device cannot compensate for the lack of light.

      Lamp light

      First prepare a place for the containers with seedlings - make a window sill, hang or attach light fixtures - hooks or \"lugs\" made by yourself, make wiring from the socket to the place of additional light.

      Before the place where seedlings will grow, it is best to install fluorescent lamps with a special sputtering, which will provide the seedlings with the necessary red and blue light. These lamps should be placed over a window sill or shelf so that the light from them hits all the plants.

      You may also use special violet-pink spectrum phytolamps for additional seedling light, they are the best lights for growing seedlings. However, this light is harmful to the human eye, so a special reflector is attached to them.

      Tips for lighting seedlings

      The main thing when growing seedlings is to inspect the sprouts regularly, paying attention to the following:

      • what is the size of the internodes--not too big and thin;
      • whether the coloring of the leaves has become too pale;
      • suddenly the lower leaves have become yellow and withered;
      • the seedlings have begun to lean toward the window.

      All these symptoms indicate one thing: the seedlings are lacking sunlight and need to start extra light immediately.

      It is also important when using different types of seedling lamps not to use low-powered ones when illuminating greenhouses and greenhouses, but too powerful ones when raising seedlings at home.

      How, how much and when to illuminate seedlings. What should be the distance to the lamp.

      When growing seedlings in winter-spring time you should not neglect extra light, otherwise the plants will grow frail and weak, will be sick for a long time after transplanting to a permanent place, and their yield will be much lower than that of healthy specimens. It is just as important to use the types of bulbs that will not harm the growing seedlings, but on the contrary will activate the growth of the vegetative mass and root system.
