If you’ve ever practiced indoor growing, you know that the LED grow light market offers a wide variety of brands that employ different color spectra to deliver an indoor grow light. As such, there have always been continuous debates among indoor growers on the best grow lights that produce the highest yield.

A common debate subject for growers recently has been the effect of white LED lights on indoor cultivation. While they have traditionally been used for lighting purposes, white LEDs can actually be employed as an indoor grow light as well.

But are white LED grow lights good for growing? In this post, we look at what exactly white LED lights are and try to establish their effectiveness when it comes to indoor plant growth!

Are White LED Grow Lights Good for Plant Growth?

A full spectrum LED will perform better than a similar wattage white LED any time since it uses the most efficient color spectrum needed by plants. Full-spectrum LEDs consist of diodes from 380 to 760nm and include a small number of white diodes to complete the color range.

On the other hand, a white LED grow light lacks some very essential parts of the light spectrum, including UV (ultraviolet) and IR (infrared), as well as far red. Ultraviolet and infrared are outside the visible range and do not exist in white light.

The role of UV diodes is to enhance the production of resin to form more trichomes. This results in healthier plants with better flavor, aroma, and potency. Meanwhile, infrared assists in flowering and stem strength.

These are both missing factors in white LED light, meaning that the LEDs cannot offer plants these useful wavelengths of the light spectrum. The plants will, therefore, produce fewer trichomes and be less potent, aromatic, and lack flavor.

Factors To Choose For Buying A LED Grow Light

Before choosing the full spectrum led grow light look into these important features.

Light proportion

Light proportion or ratio means the present spectrum of your lights. Spectra are essential for growing plants. They make them big and full with flowers and fruits. Usually, they get it from sunlight which helps them with the photosynthesis process. That is why it’s important to horticulture or other plantation. Plants usually prefer yellow, orange, red, blue, and in some cases UV and IR. Your LED grow lights should contain all these spectra.

Light intensity

Another essential factor light intensity that helps to grow plants healthy and colorful. So choose the brightest LED grow light for having good shaped green leafs with big branches. Lack of light can make them leggy and tall. Also, it can turn leafs yellowish too.

Energy-saving and power-efficient

The led grow lights are well known for light intensity in low electricity. But still, some grow light devices can be a headache of your rising electricity bills. So, choose the light that uses less power but ideal for bright lights and full coverage. Your LED grow lights should have the power to produce much light without using high power.

Watts are what matters to plant growth in many ways. Of course, the whole science of plantation and your experience on it does matter too. It can manipulate the illumination intensity, temperature, and nutrients. Cheap led high watts grow lights can increase the growth as well as the whole temperature of your garden. And the electricity cost.

Duration of light

A good quality light should have a long lifespan. Usually, people think cheap lights have a low lifespan, and the expensive one has high. But the price always determines the longevity. So check out its performance rating by real customers. Longevity and good performance are important for your plants. It stays with your plants under all stages of growth.

Maintenance cost

Usually LED lights do not need high maintenance costs. But in some cases, the cheap light will burn out in 3/4 days later after installing. Some use timers also to control the power switch. But, the quality of the light will save your money on maintenance.

High power cooling system

The best grow lights can heat up which bad for the plant and also for the device. So lower temperature is a must for your indoor garden. A lower working temperature light can take care of your plants better than others.

Constant current driver circuit

An ideal LED circuit should supply continuous power. It regulates the intensity as the temperature changes. Lights with bloom & veg mode are great at providing the right intensity for your plants needs.

Does more light equal more yield?
  • You may not realize it, but by asking that question you have touched on one of the biggest discussions in the indoor grow lighting industry, as well as the indoor gardening community. 

When you get into how it all works, light is some amazing stuff. It doesn’t really act like anything else in the world, so it can be difficult to visualize how it works without having something else to use as a comparison or reference. For example, we may imagine light pouring like a liquid or like smoke, until it fills a space up – that’s close, but not quite right. We could describe it as being like radiation, emanating out and being absorbed by anything in its path…a little closer, even, but still not exactly the same thing.

Light has unique properties – in order to determine whether it is as simple as (more light = more growth) or whether dumping all those photons is wasteful or even harmful, we need to better understand how it works in the first place.
