Many people wonder: what kind of hemp lamp should be used to illuminate sprouts indoors? Of course, the best lighting for young and adult plants is the sun, which provides ideal conditions during all phases of growth. Therefore, it is so important to create a plant environment that is closest to natural.
The impact of various spectra on the phases of plant growth
As we know from physics, light itself is not a homogeneous substance. In fact, it is a wave in various ranges and frequencies, forming a spectrum of light sometimes invisible to the human eye.
Hemp plants growing in the natural environment, from the entire spectrum of colors, perceive especially strongly long ultraviolet rays, which trigger the synthesis of chlorophyll. This allows the shoot to be most efficiently nourished with vitamins and nutrients for future growth. This spectrum is recommended to be used in the initial stages from the moment the seed hatch, and before it became a small bush.
Another spectral range that has a beneficial effect on plant growth is red light of reduced intensity. It was found that such radiation affects the speed of development, plant height and yield, thereby stimulating photosynthesis inside the plant. What kind of lamps are needed for growing hemp? You should choose options with the characteristics listed above.
Using this knowledge, you can choose the most suitable lamp for growing hemp in closed ground. However, it must be remembered that hemp is a moody plant. Therefore, one should take into account the preferences of the variety relative to the amount of red and blue spectrum at different growth phases.
Lamps play two roles in growing marijuana bushes. First of all, they give light in the necessary ranges and frequencies, which we wrote about above. And secondly, the lamps emit a large amount of heat. This is important because the plant itself grows in hot countries and needs a lot of sun and heat, as well as moisture.
Now we will analyze in detail which lamps are used for growing hemp.
DNT
Arc sodium tube lamp of cylindrical shape. It produces light by heating sodium gas inside the flask, which leads to a glow in the yellow-red spectral spectrum. Such a lamp for growing hemp has proven its worth, as it provides the plant with the necessary heat and light in all phases of growth. At the same time, it is very hot during operation, which can burn the leaves of the plant. The device requires special equipment.
ESL
The energy-saving hemp lamp is suitable only in two color ranges: 2700 K (warm white, the prevalence of the red spectrum) and 6400 K (cold white, the prevalence of the blue spectrum). To achieve maximum results, it is recommended to install both spectra for lighting the bushes. The advantage is a high level of energy saving.
LED phytolamp
Lamps specially designed for growing various plants are able to provide the most comfortable conditions for future bushes, emitting only the necessary color spectrum for the full development of the plant. At the same time, they save energy, serve for a long time, are safe in operation and do not heat up. Such a lamp looks like a lot of bulbs inside a large cartridge. There are several types:
- Bicolor lamps are equipped with only blue and red light bulbs. Such lighting is ideal for the vegetative phase, as it gives the seeds and already hatching sprouts the whole necessary spectrum of light for development.
- In addition to the red and yellow spectrum, multicolor lamps are also equipped with high-beam red light bulbs, which are a secondary color. They are good to use in all life cycles of a plant: from seeds to flowering.
- Full-spectrum lamps contain the entire range of visible color, while the main ones are the same red and blue. Such a lamp is most optimal for all phases of plant growth.
Which lamps for growing hemp are not suitable
Ordinary lamps that we use for indoor lighting are completely unsuitable for growing. They do not emit the necessary spectra of light, without which hemp cannot fully develop. In addition, they produce too much heat, which can damage and burn the leaves, thereby destroying the plant.
Halogen lamps, too, are not suitable for such an occupation, all for the same reasons. There is no necessary spectrum, and strong heating will not produce the desired result in any growth phase.
Household LEDs and energy-saving lamps are not suitable solely for the spectral composition of light.
We hope that this article helped to find out which lamps experienced growers use for growing hemp. This article is for informational purposes only, in no case does it encourage the cultivation of hemp in the Russian Federation, as this is prohibited by law.
