Differences Between Purple Grow Light vs White Light

The growth and health of a grow tent depend on proper nourishment. A grower has to maintain a suitable and artificial environment for his plants. The grow light is the most important element of any indoor gardening. The healthy growth of plants largely depends on it. So you have to choose it very carefully. 

Grow light helps the plants of the tent flourish. It is a type of electric fixture that is used as an alternative to sunlight. It ensures detailed and tailored spectrum and luminous efficacy which is necessary for cultivation.

You have to maintain every single element very carefully to create the outside atmosphere for your plants. The lights and their shade should be determined by the type of plant you are planning to cultivate. 

Both purple and white lights are two of the widely used grow light fixtures in an indoor garden.  There are many controversies on the differences between purple grow light and white light. While analyzing the impact of light you have to check out the stage of the plants like germination or fruiting in order to fix the necessary photoperiod for them. 

White and purple light, both have significant parts to play in the field of plans. But you only need one. So you need to have a clear idea about both. Let me tell you a little about both the lights, their functions so that you can clearly make up your mind about purple light vs white light. 

Purple Grow Light

Purple Grow Light

Well, There is a clear scientific explanation behind the effectiveness of purple grow light. Photosynthesis is the most complex and important chemical mechanism that occurs in the green leaves of the tree. The plant of a grow tent produces their food through photosynthesis which is specially directed by the purple grow light. Grow light is most of the time formulated to produce purple light. Why is that? 

When light is made with the mixing LEDs of red and blue it reflects purple color together. 

Horticulturalists say that they try to use purple light in their growing environment to create suitable frequencies for accelerating photosynthesis. 

The two prominent colors that play a crucial part to create purple light have their own effects on the health of the plants. The organic function of the leaves such as the participation of the chloroplast, stem, and overall petiole growth of the plants depends on the red light. Moreover, it helps to generate the reproductive system, flowering, and fruiting of the plants.

The growth and expansion of the organ of the plants are defined by the blue light. Stomatal opening for the processes of Photomorphogenesis, and photosynthesis occurred in the presence of blue light in the growing system. 

Thus, with the help of blue and red light, a purple outcome is produced. This happens to ensure a required amount of necessary lighting frequency to get vegetative growth from the plants.

Best purple grow light 

Purple grow light is a mixing light that the growers used most often in their indoor gardening room to provide the plants UV-A and UV-B. But you have to choose the best purple light for you as the manufacturer might not be cautious about the health of your plants. Check the efficiency of the light or you may purchase it from a trustworthy and renowned shop to avoid the wrong choice. A perfect purple grow light has the following qualities: 

  1. The two prominent colors that are used to make purple light should be measured by experts.it can transfer the light energy into photons so that the plants absorb them for growth.
  2. Mixture 80 to 90 percent red and 10 to 20 percent blue light. 
  3. A premium purple fixture can accelerate the metabolic strength and ensure the rapid growth of your plants.
  4. RED light here is used for the enhancement of the plant. Blue light is used to make plants grow shorter according to the growers requirements. Again, it helps to attain the demanding compactness of the plants.

The purple grows light should be used very carefully for the cultivation as there is a huge impact of light frequencies on the plants. Choose the best one sensibly so that it may not mislead your plants in their crucial stage of growth. Don’t use purple to your plants as it is often unworthy for growing plants. It is also responsible for the reverse impression of purple grow light. 

White light

White light

Basically white light is the mixture white light is a mix of blue, green and red wavelengths. There is no specific white wavelength/ spectrum. 

The common characteristics of white grow light are that lights are eye-soothing and provide slight full-spectrum wavelength to the plants. 

Though it provides nutrition, sometimes it’s not enough for the demand of your plants. Home growers are suggested to use white light in their growing area. It doesn’t change the natural color of the tree. The only downside of white light is it can’t ensure the swift growth and timely flowering of your plants.

White LED Light 

Basically, all white LEDs are truly blue diodes that are covered with a substance called phosphors which change a portion of the blue light into longer, less vigorous wavelength.This type of white lights are mostly made for normal use. 

The popular demand has prompted fast innovative advances of the blue LEDs to make white LEDs. Thus, at a cheap rate you can get  effective (white) LEDs.

There are basically three types of white grow light used in grow tents. These are 

  • the mint-white: Slightly greenish hue. 
  • warm-white : Soft reddish hue 
  • Cool-white: Bluish hue. 

The shade of the white LED relies upon the phosphors used to change over the blue light into green, red and far red

One more approach to make white light with LEDs is to mix blue, green and red LEDs.However, , this is generally not done on the grounds that green LEDs are considerably less proficient than red and blue LEDs. 

White light for plants:

White light is used by several types of indoor cultivators. White grow light produces a light wave of many colors. There are some common impacts you might notice in white grow light. These are:

  1. The plants will get many types of spectrums from white to grow light that ensures necessary nutrition to the artificial growing environment.
  2. If you are planning for a short growing plant inside your home white light can be  useful to you. It is able to provide many sorts of shades to the plants.
  3. White light can’t produce any particular color acutely. Sometimes it hampers the flow of necessary elements to the plants. so, you have to combine some other lights to get a better result

Differences between purple grow light vs white light

purple grow light vs white light

There are many manufacturers and functional differences between purple grow light vs white light. A grower has to determine which one he should apply for his plants based on the types and developing level of the cultivation.

Purple LED consists of a combination of above 80% red and 20% of blue lights that provide you an excellent outburst. The efficiency of red light is so acute that it converts electricity into photons to boost photosynthesis. If you want to increase the growth and compactness you can add more blue lights to it. But the combination of these two colors may mislead you to trace out the real color of the plant inside a greenhouse. 

On the other hand, white light is prepared with the amalgamation of 7different colors of the spectrum. Different types of white light emit different lights which are modified by the phosphors used inside the light. Though the white lights are eye-soothing they don’t serve your plants like purple light. 

Another difference between purple grow light vs white light is the formulation of the far-red light effect. This is very necessary for the growth and early flowering of the plants. Far-red white LED lights are really rare. This is the modified version of red light. Since it only has a slight red effect, the plants might grow taller and flower ahead of schedule. But it is absent in the purple light. 

As white light can’t inspire plants in photosynthesis like purple light, the plants’ insight home wants to maintain a lower level of CO2 and a higher level of O2. But purple light is comfortably absorbed by the chlorophyll of your plants. And work perfectly with it. 

 Should I Buy Purple or White Grow light? 

Now, after everything, this is what it comes down to. What should you buy for a healthy growing system? Well, we would suggest buying a light fixture that has a bit of both. 

You will find many LED lights that offer a combination of small white, red and blue leds. You will get the necessary wavelength there. Your plants will thrive under those lights. And another plus is you won’t frequently have to change lights according to the plant’s grow phase. 

Frequently asked the question:

Are purple grow lights better?

Purple grow light ensures the light wave of blue and red that are very helpful for the plant’s metabolism and flowering. That light consumes low energy and temperatures. If you want to have a handy and easy use of grow light for better output, purple grow lights are the better choice for you.

Is white light or purple light better for plants?

 

Both white light and purple light serve your plant’s proper light frequencies. The difference lies in their efficiency. As white light covers up the full spectrum it cannot provide the requirement of a particular light frequency. But purple light ensures the most important demanding color frequencies of plants. 

How is Purple light important for plants?

According to the botanists’ plants react separately in different colors. In comparatively short waved violet or purple color leaves get high energy. It will be helpful for sprouting and vegetation.

Conclusion

There are technical and functional differences and controversies in Purple grow light vs white light. Each light has its own capacity of creating an artificial light spectrum to make the plants comfortable. A cultivator should choose the right one for his plants on the basis of the types, growing stage, and the requirements of the plants. 

Try to examine the health of the plants and have a discussion about the problems of the plants with horticulturalists. Maintain a proper guideline to have a bounce of flowers and fruits from your plantations. And if possible buy a full spectrum LED that offers all the wavelength.
