are white led lights good for growing

When it comes to smoking weed, there are two types of stoners – growers and buyers. Buyers don’t like growing and growers usually don’t like buying. Once you start smoking weed regularly, you eventually figure out who you are. Most stoners usually start off as buyers but once they start growing their own weed – they become growers for life. Growing weed is a process which involves a lot of emotional investment. You begin to care for the plants that you are growing and you become attached with their growth and their daily needs! It is almost like having a child – and you want to make sure that you are providing the best care for your child.

When it comes to providing the best care for your weed, you need to make sure that you are providing your plants with the best quality of LED grow lights – these lights come in various colors, and it is important to know how your plants react to each of these lights. White LED lights in particular are of quite an importance, but you need to know exactly how and when to make use of this light and more importantly: Are White LED lights good for growing weed?

In this article, we take a closer look at all LED lights, but more specifically, the focus will be on White LED lights and how important they are when it comes to growing your own weed indoors

What Are Grow Lights? Why Are They Useful for Growing Weed?

Grow lights are among the most critical components when it comes to growing weed indoors. Out of all the three natural elements that are needed to grow weed (sunlight, water and air), light is the most important because it provides not only energy but also food to the plants by enabling photosynthesis. However, when you grow your cannabis plants indoors, you need to ensure that they get appropriate lights and heat in an indoors environment which is often hard to emulate. Hence, you need to select the best grow lights which ensure that your plants get the best of lights and heat. 

LED stands for Light Emitting Diodes. For those wondering how these LED lights can emulate the spectrum of light, it is with the help of two different semiconductors. The first of the two creates a negative charge (electrons) while the second type of semiconductors create a positive charge (holes). Other types of lights create light and heat based on different material such as mercury, gas or filaments. However, LEDs have a different way of creating light which is actually way more cost-effective compared to the others. They are also more durable and environment-friendly compared to the incandescent lights. 

The spectrum of lights that LED Grow Lights emit can be of various types: some of them might actually be quite similar to the wavelength of the sun. However, there are others which provide certain specific wavelengths focusing more on the reds or the blues which contribute to the growth of the plants in a specific way. However, here, we will be focusing not on the reds and the blues, but on the whites! Here’s a closer look at White LED lights and why they are important –

Understanding White LED Lights: What Are They?

Now that you understand what LED lights are and why are they important for the growth of your cannabis plant, let us give a closer look to white lights and what makes them so special and so different. 

While there are a number of colors of lights that come into effect when it comes to growing a cannabis plant, white lights are the ones that matter a lot. A white-light spectrum consists of six lights at different wavelengths. These lights are of violet, blue, green, yellow, orange and red colors. Each of these lights is a part of the white-light spectrum at different wavelengths. 

In this, violet light is usually present at 380-450nm, blue light at 450-495nm, green light at 495-570nm, yellow light at 570-590nm, orange light at 590-620nm and finally red light at 620 to 750nm. While most spectrum of lights will have all of these colors but the intensity of the wavelength of the lights will be different.
