The Benefits Importance of Ultraviolet(uv)  Spectrum Led Grow Lights for Plants

uv plant lights

Ultraviolet UV light is electromagnetic radiation transmitted from the sun at different frequencies and wavelengths. Ultraviolet light has several uses, such as in tanning, photography, cancer treatment, and lighting. This article focuses on the importance and benefit of using ultraviolet light to facilitate the growth of plants.

Usage of ultraviolet light to grow plants

Plants require light to grow. The plants growing outdoors can feed off the natural sun’s energy for photosynthesis. The more plants are exposed to UV lights, the more they absorb all nutrients needed to give a bountiful harvest. Indoor UV lights for plants are necessary for indoor plants to promote photosynthesis depending on the light the plant gets.

Ultraviolet grow lights

Ultraviolet grow lights are essential for individual and commercial growers who cultivate their seedlings indoors. Modern grow lights have been infused with ultraviolet radiation to provide UV wavelengths necessary to increase the plants. The ultraviolet grow lights are required for budding, flowering, absorption of chlorophyll, photosynthesis, and growth of plants.

The lights have different spectrum range that is measured by a nanometer. Where your goal is to heighten chlorophyll absorption to promote photosynthesis, you require blue glow light ranging between 400-520 nanometers. When your goal is to encourage budding and flowering, you must use the red glow light that runs from 610-720 nanometers.

Led grow lights UV

Led grow lights UV give your plants a glow vital to plant development. Manufacturers have produced led lights that have a combination is wavelengths necessary for the plant to grow. Led grow lights UV offer light in different color ranges and wavelengths that plants require for growth, development, and flowering. The led grow lights provide a purple glow, a red glow, a blue glow, a white glow, or a green glow.

The purple glow is a combination of the red and blue wavelengths. The two wavelengths activate the chlorophyll pigment in plants causing photosynthesis upon their absorption by the plant. The blue wavelength contributes to the health of a plant leading to larger plants with a darker green color associated with shorter, thicker stems that grow at an accelerated rate. The red glow wavelength regulates plants’ growth, increasing photosynthesis while leading to tall and long plant stems.

UV lights for indoor plants must have a combination of the red and blue wavelengths to allow indoor plants to bloom as though they are grown outdoors, where they feed off the natural ultraviolet UV light from the sun. The combination of the red and blue light lengths provides the night and day cycle plants need throughout their growth.

White led grow light is a good option for UV lights on plants. The white led grow light is optimal for the environment and ensures plant health. Further, the white glow light is better for vegetative growth, flowering, and fruiting.

Green grow light is especially important for young plants that do not produce adequate amounts of chlorophyll. It provides the young plants with increased chlorophyll pigment responsible for photosynthesis. The green growth light quickly penetrates the plant canopy to reach the lower branches. The light is significant in promoting germination, vegetation, and flowering.

Why you should use led grow lights UV over fluorescent bulbs

  1. Led lights maintain a constant warm temperature without getting too warm over an extended period which is safe for your plants. While they produce warmth, the led lights have a heat sink on their base that cools the bulb. Fluorescent bulbs, on the other hand, make too much heat that is harmful to the environment and the general growth of your plant.
  2. Led lights are safe and non-toxic as they are powered by an electrical current that illuminates due to the tiny diodes in the bulb. Fluorescent bulbs emit mercury vapor to light the bulb. Mercury is a heavy and toxic metal that causes environmental pollution and affects the life of critical organs and plant cells when released into the air.
  3. Led UV plant lights are energy efficient, adjustable, and can be tuned to ensure maximum yields. Plant UV light should be cost and energy efficient while providing maximum yields. Led lights will provide you with a money-saving venture while providing you with products. Fluorescent bulbs are not energy efficient as they produce too much heat that may cause a plant to wither.

UV lights for growing plants indoors

Indoor plants require as much light as their counterparts. Is UV light for indoor plants necessary for a plant to thrive? Generally, plants produce natural sunscreen from the light spectrum, and it is, therefore, necessary to supplement a good portion of UV ultraviolet light. The same is possible by getting a UV plant light or a plant UV lamp to promote the exposure of UV light on plants.

Why do you need UV plant grow light?

UV plant grow light is necessary for speeding up the germination of seeds. When planting seedlings, you should avoid planting them in intense lighting. The UV plant grow light is a good start for your seedlings bench. They produce sufficient light for indoor seedlings that do not require a standard light source as they germinate. As a grower who transplants seedlings, you must start with UV plant grow light that does not expose your seedlings to harsh and high-intensity light.

Do UV plant lights work?

UV plant lights are an alternative to natural sunlight that indoor plants cannot access since they are grown indoors, and natural sunlight may not adequately reach them. UV plant light is essential to plants since it helps them protect themselves against sunburns, enrich the fruit’s taste, smell, and color, and aid in germination. UV plant lights emit ultraviolet light, similar to the sun’s, for a happy and healthy plant.

Benefits of UV light

Ultraviolet light benefits are valuable and incredible for farmers. When you expose your plants to UV light, the UV light benefits can easily be spotted where you expose your plants to the perfect balance of UV light. Where UV grow lights for plants are appropriately used, the product is high-quality plants and large yields. The following are the benefit of UV light for plants:

  1. Speed up germination. Plants need light to germinate, and UV light speeds up the process. Seedlings must be exposed to light sources to facilitate their germination. When transplanting a plant, you must move it from a relatively dark or low-intensity light to a more intense light, but you can not move it to the highest intensity to avoid shocking the plant with light. However, the plant best germinates when exposed to UV light in its early stages of germination. Science explains that young seedlings should be exposed to low-intensity of UV light to up germination.
  2. Production of oils and resins. Oils and resins are responsible for the taste and smell of plants. When a plant is exposed to enough UV light, it is more likely to produce the delicious aroma and taste in the fruit that the plant has. UV light is responsible for the smell and taste that plants possess. The resins are responsible for the vibrant colors that create plants’ beauty.
  3. Increased root mass. Most plants absorb nutrients from the ground using the roots. Where a plant is exposed to UV light, it has a more extensive root base which reflects an increase in the minerals and nutrients the plant obtains from the soil. The effect is that the plant can acquire all the essential minerals, vitamins, and nutrients necessary for its growth.
  4. Increased potency. The success of a plant is measured by its harvest. Where there is a bountiful harvest, it is a clear sign of adequate exposure to UV light. Where plants are exposed to UV light, there is an increase in flowering and seed production which is the measure of potency for a plant. A plant UV lamp helps provide an adequate supply of UV light for plant growth.
  5. Increased resistance to fungus, bacteria, and pets. When a plant is exposed to the UV, it creates trichomes as sunscreen to shield itself from harmful UV light. Trichomes produce a sunblock against radiation that could potentially kill the plant. Furthermore, resins perform a protective role by protecting the plant against harm from insects, infections, and fungi.
  6. Promotes healthier, thicker, and taller stems. A tree leads to an increase in photosynthesis upon feeding on the UV light. A plant that has sufficient exposure to UV light has healthier and greener leaves due to an increased amount of chlorophyll. Further, the stems and branches of the tree are strong and can easily branch out, leading to a big healthy plant. The stem grows in length and girth, leading to a healthy plant.

Caution against overexposure

While UV light benefits plants, too much exposure to UV light over a prolonged period causes stunted growth and development. The stunted growth is apparent through the yellowish leaves that are wilting. Further, introducing UV light in the first developmental weeks may reduce the flowering ability of some plants, such as cannabis. It is, therefore, safer for you to introduce the UV light during the final stages of flowering.

Another adverse effect of overexposure to UV light is bleaching and discoloration of the plant cells. The plant loses its green matter, chlorophyll, and results in underwhelming yields. The fruits lose their scent and flavor, leaving them tasteless due to being bleached by the sun.

How to use UV plant lights

A plant UV lamp can be used in your grow room to promote the growth of your plants. UV lamps for plants must be carefully selected to ensure you have the perfect wavelength of UV lights for your plants to yield fruit. Consider the following factors before using UV grow lights.

  1. The needs of your plant. Plants need light to grow, but some plants which do not produce resins will require less exposure. It would be best to determine whether your plant benefits from UV light to have resins so that you put the UV plant lights where there is sufficient light for resin production.
  2. The space available. While your plants require light, if you place the UV plant lights too close to the plant, the UV light will likely bleach the plant’s leaves, leaving it wilted and not bearing fruits. You must place the lights at a safe and slightly distant location away from the plant.
  3. Safety precautions. The goal is to avoid overexposure of your plants to the UV light. Too much of anything is poisonous, and the same works for plants and UV light. Overexposure will cause stunted growth; therefore, you must implement measures to avoid the destruction.
  4. Cost. Remember the installation and maintenance costs of incorporating a UV system and the wavelength range necessary for your plants.

Ultraviolet grow lights

Three types of UV light can be consumed by both plants and animals. UVA is produced by the sun in the natural environment where the plant grows. It is ingrained in the plant’s DNA and valuable for indoor growth.

UVB is released by the sun, and each plant has a different reaction. Primarily, it protects plants against microorganisms and boosts the terpenes and color of the plants. Further, it is an additional indoor UV for plants. UVC is the harshest of light. It is not produced by grow lights and can easily damage a plant’s DNA, so it is not used for plants.

Technology has evolved; therefore, artificial lights are infused with UV plant grow light. UV grow lights for plants promote optimal health and development. UV light plant growth can also be obtained from artificial lights with the UV spectrum. Artificial led lights contain the UV light wavelengths that promote your plant’s growth. Ensure that you select a reputable led grow light that does not include the UV-C wavelengths that are dangerous for your plants.

Plant UV lamp

Plants need ample lighting to reach their highest potential. When sunlight is not enough, you should supplement it by using plant UV lamps to greatly benefit your plant’s growth. A plant UV lamp is a preferable grow light that supplies your plants with the right amount of UV light. The lamp provides ultraviolet light to grow plants, strengthen them, and speed up germination.

Take caution in hanging the plant lamp because if you place it too close to your plants, it increases the risk of bleaching them due to exposure to UV lights. The plant UV lamp should supply wavelengths of UV light necessary for your plants. The selection is unique to your needs because if you require fruits, you need the red glow light, and you will require the blue grow light for thicker stems.

How to set up and light an indoor plant growing area with ultraviolet light to grow plants

The first step is to identify the location of your indoor garden. Ensure that you select a space to dedicate to your plants, either in plant pots or in seedlings’ bedding. The second step is to decide on the plant you are growing and to plant it in the bedding or pots, leaving space for pruning. The final step is to purchase and fix the bulb that will provide UV light for the plants. Ensure that you have good bulbs that can illuminate the growing area and avoid too many UV light sources, as they will harm your plant and cause withering.

Safety Precautions where one has ultraviolet grow lights

Just like you should never stare into the sun, you should never directly look into the grow lights. The intensity of the UV light could cause irreversible harm to your eyes. Your eyesight will be grateful when you protect your eyes from electromagnetic radiation using safety glasses. You will moreover need to protect your skin against any prolonged exposure.

Even upon a short burst of contact, ensure that you always have safety equipment. While grow lights do not have UVC, it is crucial to take care of your body, eyes, and skin or plants since it is not an essential requirement to flourish.

Caring for your plant grow light

The general rule is that a plant should receive light for at least sixteen hours and be in darkness for eight hours daily. Your grow light should, therefore, not be kept on for twenty-four hours a day; it needs its rest just as much as you and your plant do.

The light should be positioned overhead as it mimics the sunlight to provide light to all the leaves and sides of the plant. Place the overhead plant lamp at least twenty-four inches above your plant. The regular checks and maintenance include dusting the light lamp, wiping it with a dry cloth, and changing batteries.
