WHICH PLANTS ARE SHADOW-LOVING, LIGHT-LOVING AND SHADOW-BEARING – THEIR BACKLIGHT

Supplementing plants in winter

Supplementing plants in winter

The period has come, when the number of sunny days decreased and daylight hours decreased markedly. But the development of our green pets directly depends on its length and light intensity.. By changing the time of the photoperiod (daylight hours), flowers can be maintained in a state of vegetative growth. How to properly organize supplementary lighting of indoor plants, experts will tell.

Useful Tips

  1. To stimulate the flowering of chrysanthemums, kalanchoe, slum berger, punches, begonias Elatior, eternal, many orchids, it is necessary to reduce the length of daylight hours (no more 9-12 hours).
  2. Supplementing the views of long daylight hours (eg, gibiskus), you can artificially prolong their flowering.
  3. If the ornamental plant does not stretch and does not lose the color of the foliage, means, light is enough for him.
  4. The distance from the lamp to the crown of the crown should be as small as possible, but not less 15 cm. When it is doubled, the amount of light decreases by 4 times.
  5. Use a reflector, this increases the illumination of the collection.
  6. Follow, so that the flowers do not overheat from the lamps.
  7. Good, if artificial lighting is not a complete replacement, but only a supplement to sunlight.

SHADOW FLOWERS

Syngonium, epipremnum, scindapsus, philodendron, anthurium, ferns, aspidistra, aglaonema, dwarf ficus and others.

Can do without backlighting.

LOVE FLOWERS

Most of the succulents, almost all bulbous, gas, haworthia, aloe, milkweed, pachypodium, hippeastrum, strelitzia, rosemary, feijoa, laurel noble, citrus fruits, etc..

Requires mandatory backlighting in low light conditions.

SHADOW FLOWERS

Tree ficuses, avocado, eucalyptus, balsam, Saintpaulia, begonia, kalanchoe, callisia, dracena, Schlumberger, cyclamen, most aroids, etc..

Tolerate a temporary lack of light. Backlight is desirable, but not required. They will not die without her, but the crown may lose compactness.

LOAD FOR BALANCE

Artificial light must fall on the plants from above. In this case, they will not waste strength and energy to change the position of the leaves.. To keep growing and blooming, necessary 12-14 hours of continuous lighting. Light intensity, at which a balance is achieved between photosynthesis and respiration for different plants, not the same. for example, light-loving need 5000-10000 lx, shade-tolerant - 700-2000 lx. Create groups of plants with approximately equal illumination.

WITH EXCESS OF LIGHT

When plants are illuminated around the clock, the process of cell growth is inhibited by stretching.

A negative effect can manifest itself as the destruction of chlorophyll, yellowing leaves.

Some lamps increase the ambient temperature, exclude natural daily fluctuations, which also inhibits growth and development.

Unfavorable changes in external factors lead plants to a state of stress, for some species, such a factor is round-the-clock illumination.

AT NIGHT – ALL SLEEP

24-hour plant illumination is undesirable, in most cases even harmful.

for example, in adult specimens, the cyclic alternation of light and darkness is disrupted, what inhibits the process of transition from vegetative to reproductive state - flowering and fruiting.

Choose the optimal length of daylight hours based on the needs of a particular plant, roughly: for tropical species - about 12 hours, for subtropical - 9-14 hours(depending on the season and stage of development).

AVOID SHADING

Illumination intensity drops sharply as you move away from the light source. If there are many plants and they are of different heights, low ones will be shaded and their growth will slow down. What to do?

  1. Trim the taller tops. This will promote the growth of side shoots.. If you want to keep it, bend with an arch and secure with rope. As soon as the buds hatch in the axils of the lateral branches, remove the rope, lest the stem breaks, reaching for the light.
  1. Place low plants on stands.

LIGHTING AND LIGHTING OF PLANTS IN HOME CONDITIONS – FLOWER TIPS


Nuances of lighting plants at home

Creating a mini-vegetable garden on the window in winter, not to do without additional lighting. It is also important to observe the temperature regime.. Only onions and watercress grow well without a lamp.. But with supplementary lighting, vitamins accumulate in greens more.

  1. Light is one of the main conditions for the life and development of plants, after all without it photosynthesis is impossible, when organic matter is formed from water and carbon dioxide. As soon as loops appear on the surface of the soil, urgently rearrange boxes with crops or cups under the lamp (it must be installed at a height 10 cm from plants). Raise the lamp gradually as needed..
  2. The first 3-5 days seedlings need to be illuminated around the clock. Seedlings at an early stage of development do not yet have roots., which means, she cannot take food from the earth, but still has to get it from outside. It is at the expense of light that young sprouts will feed at the beginning of their journey., will form chunky. Roots are formed in a few days, and then the night light is not required. On average, the seedlings are illuminated to 14-16 hours.
  3. After the emergence of seedlings, you need to reduce the night temperature.. Plants breathe at any time of the day, and a large supply of food is consumed in the process. Let's assume, that your seedlings do not have enough light, which means, that with poor photosynthesis, nutrients are not formed enough. At night, when breathing, they are quickly consumed., and nothing is left for growth (here's a frail seedling).

When the night temperature drops, we create conditions, in which the plant breathes less intensively, which means, and spends less food.

WHICH LIGHTS ARE SUITABLE FOR INDOOR FLOWERS

pleases, that there are more opportunities to provide indoor plants with artificial lighting. But the more difficult it is sometimes to choose the best option for lamps. We have prepared for you a "guide" to the most common.

Conventional incandescent light bulbs with tungsten filament Low light output, because more 90% all the energy consumed goes to heat, drying plant leaves. uneconomical. When hit by drops of water burst. May come in handy, eg, in a showcase with tropical plants for heating and lighting, but need a thermostat
Fluorescent low power, therefore, they are mounted in several pieces and be sure to install reflectors. Tolerates dirt and water droplets when spraying plants. Affordable. Little heat dissipation. energy saving. Use cold spectrum lamps, as from a warm plant they stretch
Phytolamps LED (LED) Better for photosynthesis (selected light waves), than previous, however, their lilac-pink glow is unnatural to human eyes.. Therefore, in residential premises, these special lamps are equipped with an external mirror reflector.
Arc mercury luminescent physiological (DRLF) They shine brightly and powerfully. Use in residential areas is prohibited due to eye exposure.. Suspended in greenhouses in the industrial cultivation of seedlings, in winter gardens, greenhouses
Arc sodium mirror (DNAZ) Favorable spectrum for photosynthesis, stable luminous flux. Equipped with a built-in mirror reflector, allowing all the light to be directed to the plants. Orange-yellow glow does not irritate the eyes, what is important when using lamps in living rooms. The disadvantages include the high price and bulky control device.

Lighting my indoor plants in winter with LED and fluorescent lights

5 thoughts on “Correct supplementary lighting of indoor plants – which are shade-tolerant and which are light-loving”

  1. Zoya BELOUSOVA, r. Karaganda

    In winter I add light to the plants, even if they stand on a sunny windowsill. I use LEDs in a multi-track table lamp and phytolamps with a bracket. I take into account the radiation spectrum, the frequency and amount of light depending on the plant and the season. Large and light-loving flowers hibernate under a powerful lamp on 75 W long 1 m, seedlings and cuttings - on 38 W with blue-red glow. Pelargoniums in the loggia are comfortable under LED lighting. I light up adult plants in the morning and evening by 2-3 o'clock. During the day they grow in natural light - south side and sunny loggia. Cuttings and seedlings stand in the room, where does the backlight work 12-14 hours.

    All lamps are installed on top and should not be heated. The distance from them to plants is from 10 see to 45 cm, optimal - 20-25 cm. Best emission spectra: blue (for seedlings) and red (for flowering and ripening fruits). With a lack of light, the leaves become small, turn yellow, dry up - noticed on those pelargoniums, which remain in the corners and the lighting from the lamps does not reach them. However, brown spots appear on the plates from its excess., flowers fall. I put specimens with a high crown away from the lamp. I raise it over the seedlings and cuttings as the pets grow older.

  2. Гемантус белоцветковыйдополню
    Оптимальное место для него — западный или восточный подоконник. На южном летом растение следует притенять, защищая от прямых солнечных лучей и перегрева; полив — обильный. Можно выносить гемантус в полутень на открытый воздух (balcony, garden), но нужно защитить от осадков и сквозняков.

    В период роста до начала цветения (цветет продолжительно с лета до осени) растение подкармливают каждые 2-3 weeks of complex fertilization. Луковицы гемантуса зацветают в возрасте 3-х лет.

  3. Многие хотят, чтобы и зимой у них шикарно цвели, eg, сенполии или фаленопсисы, но при этом пренебрегают досвечиванием. А ведь питомцам катастрофически не хватает света. Повесьте над подоконником хотя бы одну агролампу и любуйтесь крепкими цветущими розетками.
    Если растения пребывают в состоянии относительного покоя в прохладной лоджии или на подоконнике, то дополнительный свет им не нужен. Для них включаю лампу в конце января, чтобы поддержать здоровье и внешний вид.

    Чаще мы сосредоточены на выборе лампы по мощности. Но сейчас подобрать нужную по различным таблицам нет проблем. Я прежде всего обращаю внимание на график спектра. У одной лампы можно видеть преобладание синего, который отвечает за развитие корневой системы (рассада или черенок получаются компактными, do not stretch). Но для взрослых растений, чтобы они зацвели или дали урожай, нужно больше красного. Вот почему пользуюсь двумя лампами на разных этапах развития.

    СВЕТ ДЛЯ ДОМАШНИХ ЦВЕТОВ

    На улице зима, и всем так не хватает солнышка, особенно нашим растениям. Некоторые мы отправили на отдых, другие вытягиваются и сохнут. Если для нас недостаток света — причина сезонной хандры, то цветам солнце нужно для питания. Поэтому питомцам дорога — под лампы и светильники.
    Наши зеленые любимцы нуждаются в лучах красного и синего спектра. Причем оптимальная интенсивность освещения для них человеческому глазу всегда кажется чересчур яркой (как в операционной). Исходя из этих особенностей и нужно подбирать источники света. Самые распространенные — лампы накаливания Они не очень подходят для растений, так как в спектре их излучения мало синих цветов, имеют слабую светоотдачу, сильно нагреваются.
    Если все же используете такие лампы для досвечивания, проведите тест — поднесите руку к листьям растения. Вы должны почувствовать тепло, но не жар!
    Для обеспечения наших питомцев нужным количеством света более приспособлены люминесцентные приборы: у них выше светоотдача, низкое тепловое излучение и большой срок службы. Однако есть и недостаток — почти полное отсутствие красных лучей в спектре.

    Поэтому хорошо использовать сразу эти два вида ламп. Именно под таким комбинированным освещением как-то под Новый год у меня зацвел душистый табак, посеянный на рассаду еще в июле. Запах новогодней елки удивительно смешивался с чарующим ароматом летних садовых цветов.

  5. Лариса ИЛЬИНА, r. Vitebsk

    Лампы над цветами включаю по вечерам до середины марта. На стеллажах подвешены длинные, в виде трубок: над полками длиной 120 cm and width 40 см — по одной люминесцентной на 40 W. Для особо требовательных к свету (citrus, фикус Бенджамина, gibiskus, myrtle) — по две светодиодных на 19 W. Высота над кронами — 10-20 cm. Хотя эти лампы не сильно нагреваются, контролирую рукой (особенно цокольные части), чтобы листья не получили ожоги.
