Do not expect a good harvest without Agriculture Fixtures Light. You can burn a lamp with the wrong spectrum and / or intensity for at least 24 hours and end up with a “donut hole”. In order for the plant to live well, it is worth choosing the right light bulb for it. Today we’ll talk about which lamps are suitable for the vegetative stage.
Plants are able to distinguish between orange-red and blue-violet light rays. Thanks to this, they can navigate in time and turn on or off the corresponding enzymatic processes.
What spectrum of light is needed for plant growth?
During the growing season, the maximum growth of the plant occurs with the help of Agriculture Fixtures Light. The root system stems, leaves are actively developing, the plant is gaining green mass. Chlorophyll production is in full swing and the plant produces as much greenery and foliage as genetically possible as long as light, carbon dioxide, food and water are not limited.
Studies have shown that two pigment systems of photoreceptors work in plants:
- One of them is based on the blue-green pigment phytochrome, which reacts to red light.
- The second system provides absorption of the blue-violet part of the spectrum, and the yellow pigment, cryptochrome, works here.
Blue rays stimulate cell division, which leads to active growth and development of leaves and stems. Therefore, at the vegetative stage of growth, it is important to focus on Agriculture Fixtures Light. Daylight hours for greenhouses increase at this stage to 18 hours per day.
Color temperature for vegetative growth period
The unit of light is the wavelength. The wavelength function in the optical range is called color temperature. Color temperature is measured on the Kelvin scale. The blue spectrum corresponds to values of the order of 4500 K and above.
What lamps to use during the growing season?
Of course, you can successfully grow everything on an HPS lamp alone. Many growers recognize it as the best in terms of price-quality ratio. However, its radiation lies in the red spectrum, which means that it does not fully satisfy the needs of the vegetative stage. For best results, it is recommended to combine sodium lamps with vegetative lamps.
Consider Agriculture Fixtures Light that is most suitable for use during the growing season.
Agriculture Lights: LED lamps (LED)
Modern light-emitting diodes in LED-lamps and LED lamps for plants cover all spectrums of light and can be used in crop production both for the period of vegetative growth of plants and for flowering.
LED lamps absolutely do not emit heat, so you can save on ventilation. On the other hand, a large number of LEDs mounted on a single panel get very hot. Therefore, coolers are provided in the design. True, they do not always cope with the temperature, and individual LEDs can burn out.
Agriculture Fixtures Light: Number of LED lamps per m2
In order to calculate the number of lamps, you need to know the following parameters:
- Grow-box length
- Grow-box width
- The intensity of light needed to grow a plant
- The amount of luminous flux produced by the LED lamp
Formula:
(grow-box area * light intensity) / lamp luminous flux value
The value of the luminous flux is indicated by the manufacturer in the instructions for use of the lamp. You can also use special calculators to calculate the required number of lamps, which also take into account the height of the installation. You can easily find them on the Internet.
Currently, there is a heated debate among growers about the advantages and disadvantages of LED lamps, because they are expensive, and the benefits of using them are not completely clear.
Agriculture Fixtures Light: Fluorescent lamps (fluorescent lamps)
They are also fluorescent. The division of luminescence into fluorescence and phosphorescence is outdated and has acquired the conditional meaning of a qualitative characteristic of the duration of luminescence.
General purpose fluorescent lamps are widely used for lighting in offices and schools. And the lamp, which is suitable for the needs of crop production, is distinguished by a special coating on the glass bulb. Thanks to this coating, radiation in the spectral range of blue and red light is enhanced.
We see this glow as pink-violet and not very pleasing to the eye. Usually such lamps are marked “For plants.
Pay attention to the color temperature of the lamp
Since these Agriculture Fixtures Light generates less heat than high voltage lamps. They can be placed close to plants – at a distance of 5-10 cm. Like high pressure lamps, fluorescent lamps require the use of ballast. The total lamp power per 1 square meter of growing area should be at least 250 watts.
How to arrange lighting?
You have familiarized yourself with what lamps for growing plants are, and you probably already know which version of light sources to choose for your own conditions. Now we will briefly tell you about how best to organize the backlight so as not to harm the flora in the house. Proper illumination of the indoor plant world
- The first thing to consider is the height of Agriculture Fixtures Light from the fixtures to the leaves. The minimum distance should be 15 cm if the plant is light-loving and 55 cm if it is shade-tolerant. In addition, the light should fall on flower pots or seedlings (or aquarium flora) strictly at right angles. Otherwise, the plants will reach for the light and take on an ugly shape.
- Secondly, each specific type of representative of the flora requires its own specific light spectrum. Some flowers need the blue spectrum, some the red spectrum. You should first ask florists or read on the Internet about the requirements for growing your favorite plant, and then choose the right lamps.
- Thirdly, if for some reason you have not found a light bulb with suitable light output and spectrum characteristics. You can organize combined lighting, for example, with Agriculture Fixtures Light lamps simultaneously with Phyto-lamps, etc.
Summary Agriculture Fixtures Light
So we told you which lamps are suitable for lighting and growing indoor plants. We draw your attention to the fact that HPS grow lights, which have a light output of 80 to 100 Lm / W, will be the best options for the home in terms of price and efficiency.
If it’s possible to splurge a little more, it’s better to opt for LED grow lights, which are still superior to the sodium bulbs previously used in greenhouses and greenhouses!
