Applications and Benefits of LED Grow Lights for Vegetables

LED grow lights for vegetables enable people to grow a wide variety of crops in greenhouses and other indoor gardens. The environmental friendly source of artificial light helps the farmers to save on energy costs without compromising the quality of the vegetables. In addition to the energy savings, the LED grow lights provide more favorable conditions for better crop growth and yields.

These are ideal for growing vegetable almost anywhere indoors regardless of the weather and outdoor conditions. Further, they are also used during off seasons. Even in areas where the external outdoor conditions are favorable for plant growth, starting the vegetable in the indoor facilities ensures healthier and strong seedlings.

Compared to the conventional lights, the LED grow lights for vegetables are more superior both in the running costs and effectiveness. Although they may appear expensive initially, they have a longer lifespan and hence more cost effective in the long run

Why do you need LED grow lights for vegetables?

Traditionally, farmers have relied on nature to provide the plants with water, light, some nutrients and other ingredients for growth. However, this has a drawback in that when the conditions such as weather are not favorable, the farmers produce little or no yields from their crops. In addition, urbanization and converting of arable land to towns have also reduced the available farming land.

The global climatic changes have also had an impact on the weather patterns, which has now become unpredictable or unreliable for farming purposes.

These and other factors have necessitated the need for alternative farming technologies such as the greenhouses and other forms of indoor farming. In these facilities, the farmers are able to control the conditions to support the growth of certain crops. The farmers provide the growth medium such as soil or others for hydroponics, nutrients, water, light, and others.

In some cases, especially for greenhouses, the natural light is adequate. However, there some indoor environments which do not get sufficient amount of light for the proper growth of the plants. This could be greenhouses, partially or totally enclosed or during the winter and other seasons when the daylight is shorter. If all the cases, the right amount of artificial light can be applied for a specific duration.

Although there are several types of grow lights, the LED is superior to the other forms of lamps. This is because of the ability to  tailor it to produce the light spectrum that the plant requires. They are also more energy efficient and reliable. The other lamps produce a light comprising of the wavelengths the vegetable require, plus others which usually goes to waste.

Generally, the LEDs are more flexible and able to produce many types of light and more specifically what the plants require.

Where LED grow lights for vegetable are commonly used

  • For indoor farms that cannot get enough light from the windows or open spaces.
  • In greenhouses during the winter season when there is less sunshine
  • In indoor gardens that are totally enclosed and have little or no source of natural light,
  • For city dwellers who want to grow their vegetables indoors, in the garage, basement etc.
  • Indoor gardens where farmers grow the starter vegetable plants before transplanting them in the outdoor gardens. For example, the farmers may use the indoor garden during the winter and then transfer them to the outdoor garden during the spring.

Benefits of LED grow lights for vegetables

Other than the energy savings the LED grow lights have several other benefits that make them ideal for most farmers. These include

Gives farmers ability to grow vegetables off season

The LED grow lights for vegetables allow farmers to cultivate and harvest the any most types of crops indoors. This is usually necessary when the outside conditions are unfavorable, such as during off-season or winter.

Easy to control

When using the LED grow lights, the farmer needs to switch off the lights during the night since the plants still require some darkness for proper growth. The switching can be either manual by hand or automatic where a timer controls the lights according to a set program.

Better vegetable growth and yields

Since they are flexible and highly customizable, the manufacturers have been able to produce LED grow lights for vegetables that produce the color or wavelength matching the crop requirements. This makes it possible for farmers to mimic the peak growing conditions for any vegetable hence the ability to get the maximum yields efficiently.

Ability to provide full light spectrum

It is much easier for manufacturers to make an LED grow light that produces a full light spectrum  to meet the needs of the vegetable in all the life stages. One fixture will have different bulbs and controls to allow the farmer adjust the light and suit any stage of the plant’s growth. As such, grow LEDs provides the appropriate light for the vegetative, growth, flowering stages as well as cloning.

Longer Lifespan

With a lifespan of about 50,000 hours, the LED grow lights will last several years before a replacement is required. As such, they have little maintenance needs and costs.

No Interference

The LED grow lights do not require ballasts. For this reason, they do not emit the electromagnetic waves that can interfere with other equipment in the vicinity. As such the indoor garden can be placed anywhere, including inside the house.

Better placement opportunities for vertical gardens

The LED bulbs have smaller physical sizes and can be assembled in thinner fixtures. Consequently, these will only take little space and is ideal for stacked indoor farms when a farmer can layer in a small space. This has the benefit of increasing yields while maximizing the other conditions such as the temperature, humidity.


More target light and less heat

The LED grow lamps produces more targeted light and less heat. This is in contrast to the other types of bulbs which produce both light and a considerable amount of heat. Too much heat is undesirable since it decreases the growth rate and may even damage the vegetables.

The high efficiency in the LED grow bulbs ensures that the vegetables receive exactly what they require and that there is no excess heat to hinder their growth. This means that they can grow and blossom better.


Growing the vegetable in the indoor gardens using the LED grow lights has several advantages compared to other sources of artificial light. First, the LEDs have economical, efficiency and environmental benefits.

The LEDs, in general, consumes less power and at the same time produces less heat compared to the lamps. In addition, the LED grow lights for vegetables provide the ideal blend of light wavelengths for the optimum growth and yield.
